Technical Field

[0004] The present disclosure relates generally to biometric authentication and, more particularly, to interfaces and techniques for enrollment and authentication of biometric characteristics. Background Art

[0005] Using electronic devices to perform biometric authentication, such as face, iris, or fingerprint, is a convenient and effective way to authenticate users of electronic devices. Biometric authentication allows devices to quickly and easily verify the identity of any number of users. Summary of the Invention

[0006] However, some technologies for implementing biometric authentication using electronic devices are often cumbersome. For example, some existing technologies, such as those involving facial recognition, require the user to align the biometric features almost perfectly in the same way during both registration and each iteration of the authentication. Deviations from the alignment of the biometric features often lead to negative false positives. Therefore, the user may need to perform multiple iterations of biometric authentication unnecessarily, or may not want to use biometric authentication at all. For another example, some existing technologies rely only on a two-dimensional representation of the biometric features. Therefore, the authentication of the user is optionally limited by the failure to analyze one or more three-dimensional features of the biometric features, and may also require the user to perform additional iterations of the biometric authentication unnecessarily. In view of the aforementioned deficiencies, the existing technologies require more time than necessary, which wastes the user's time and device energy. This latter consideration is particularly significant in the operation of battery-powered devices.

[0007] Therefore, the present technology provides a faster and more efficient method and interface for implementing biometric authentication for electronic devices. Such methods and interfaces optionally supplement or replace other methods for implementing biometric authentication. Such methods and interfaces reduce the cognitive burden on users and produce a more efficient human-computer interface. For battery-powered computing devices, such methods and interfaces save power and increase the time interval between battery charges. Such methods and interfaces also reduce the number of unnecessary, irrelevant or repeated inputs required at computing devices (such as smart phones and smart watches).

For example, electronic devices need to provide convenient and effective methods for registering one or more parts of a biometric feature. As another example, electronic devices need to provide fast and intuitive techniques for selectively accessing secure data based on biometric authentication. As another example, electronic devices need to provide fast and intuitive techniques for enabling device functions based on biometric authentication.

[0154] Although the following description uses the terms "first," "second," and the like to describe various elements, these elements should not be limited by these terms. These terms are merely used to distinguish one element from another. For example, a first touch may be named a second touch, and similarly, a second touch may be named a first touch, without departing from the scope of the various embodiments described. Both the first touch and the second touch are touches, but they are not the same touch.

[0155] The terms used in the description of the various embodiments described herein are only for the purpose of describing specific embodiments and are not intended to be limiting. As used in the description of the various embodiments described and in the appended claims, the singular forms "a" and "the" are intended to also include plural forms unless the context clearly indicates otherwise. It will also be understood that the terms "and / or" used herein refer to and encompass any and all possible combinations of one or more items in the associated listed items. It will also be understood that the terms "includes," "including," "comprises," and / or "comprising" when used in this specification specify the presence of stated features, integers, steps, operations, elements, and / or parts, but do not exclude the presence or addition of one or more other features, integers, steps, operations, elements, parts, and / or their groupings.

[0156] The term "if" is optionally interpreted to mean "when," "upon," or "in response to determining," or "in response to detecting," depending on the context. Similarly, the phrases "if it is determined that," or "if [stated condition or event] is detected" are optionally interpreted to mean "upon determining that," or "in response to determining that," or "upon detecting [stated condition or event]," or "in response to detecting [stated condition or event]," depending on the context.

[0157] Embodiments of electronic devices, user interfaces for such devices, and processes associated with using such devices are described herein. In some embodiments, the device is a portable communication device, such as a mobile phone, that also includes other functions, such as a PDA and / or music player functions. Exemplary embodiments of portable multifunction devices include, but are not limited to, the Apple Watch from Apple Inc. (Cupertino, California). Devices, iPod equipment, and Device. Other portable electronic devices, such as laptops or tablets with touch-sensitive surfaces (e.g., touch screen displays and / or touch pads), are optionally used. It should also be understood that in some embodiments, the device is not a portable communication device, but rather a desktop computer with a touch-sensitive surface (e.g., touch screen displays and / or touch pads).

[0158] In the following discussion, an electronic device including a display and a touch-sensitive surface is described. However, it should be understood that the electronic device optionally includes one or more other physical user interface devices, such as a physical keyboard, mouse, and / or joystick.

[0159] The device typically supports a variety of applications, such as one or more of the following: a drawing application, a rendering application, a word processing application, a website creation application, a disk editing application, a spreadsheet application, a gaming application, a telephony application, a video conferencing application, an email application, an instant messaging application, a fitness support application, a photo management application, a digital camera application, a digital video camera application, a web browsing application, a digital music player application, and / or a digital video player application.

[0160] Various applications executed on the device optionally use at least one common physical user interface device, such as a touch-sensitive surface. One or more functions of the touch-sensitive surface and corresponding information displayed on the device are optionally adjusted and / or varied for different applications and / or adjusted and / or varied within the respective applications. In this way, the common physical architecture of the device (such as the touch-sensitive surface) optionally supports the various applications with a user interface that is intuitive and clear to the user.

[0161] Attention is now turned to embodiments of portable devices having touch-sensitive displays. Figure 1A is a block diagram illustrating a portable multifunction device 100 with a touch-sensitive display system 112 according to some embodiments. Touch-sensitive display 112 is sometimes referred to as a "touch screen" for convenience, and is sometimes referred to as or referred to as a "touch-sensitive display system." Device 100 includes memory 102 (which optionally includes one or more computer-readable storage media), a memory controller 122, one or more processing units (CPUs) 120, peripheral device interfaces 118, RF circuitry 108, audio circuitry 110, a speaker 111, a microphone 113, an input / output (I / O) subsystem 106, other input control devices 116, and external ports 124. Device 100 optionally includes one or more optical sensors 164. Device 100 optionally includes one or more contact force sensors 165 for detecting the intensity of contacts on device 100 (e.g., a touch-sensitive surface such as touch-sensitive display system 112 of device 100). Device 100 optionally includes one or more tactile output generators 167 for generating tactile output on device 100 (e.g., on a touch-sensitive surface such as touch-sensitive display system 112 of device 100 or touchpad 355 of device 300). These components optionally communicate via one or more communication buses or signal lines 103.

[0162] As used in this specification and claims, the term "intensity" of a contact on a touch-sensitive surface refers to the force or pressure (force per unit area) of a contact (e.g., a finger contact) on the touch-sensitive surface, or to a surrogate (surrogate) for the force or pressure of a contact on the touch-sensitive surface. The intensity of a contact has a range of values ​​that includes at least four different values ​​and more typically includes hundreds of different values ​​(e.g., at least 256). The intensity of a contact is optionally determined (or measured) using various methods and various sensors or combinations of sensors. For example, one or more force sensors below or adjacent to the touch-sensitive surface are optionally used to measure the force at different points on the touch-sensitive surface. In some implementations, force measurements from multiple force sensors are combined (e.g., weighted averaged) to determine an estimated contact force. Similarly, the pressure-sensitive tip of a stylus is optionally used to determine the pressure of the stylus on the touch-sensitive surface. Alternatively, the size of the contact area detected on the touch-sensitive surface and / or its change, the capacitance of the touch-sensitive surface adjacent to the contact and / or its change, and / or the resistance of the touch-sensitive surface adjacent to the contact and / or its change are optionally used as a surrogate for the force or pressure of the contact on the touch-sensitive surface. In some embodiments, the surrogate measurement of the contact force or pressure is used directly to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is described in units corresponding to the surrogate measurement). In some embodiments, the surrogate measurement of the contact force or pressure is converted into an estimated force or pressure, and the estimated force or pressure is used to determine whether an intensity threshold has been exceeded (e.g., the intensity threshold is a pressure threshold measured in units of pressure). Using the intensity of the contact as an attribute of the user input allows the user to access additional device functionality that would otherwise be inaccessible to the user on a smaller device with limited physical area, which is used to display an indication (e.g., on a touch-sensitive display) and / or receive user input (e.g., via a touch-sensitive display, touch-sensitive surface, or physical / mechanical controls such as knobs or buttons).

[0163] As used in this specification and claims, the term "tactile output" refers to a physical displacement of a device relative to a previous position of the device, a physical displacement of a component of a device (e.g., a touch-sensitive surface) relative to another component of the device (e.g., a housing), or a displacement of a component relative to the center of mass of the device that will be detected by a user using the user's sense of touch. For example, when a device or a component of the device is in contact with a surface that is touch-sensitive to a user (e.g., a finger, palm, or other part of the user's hand), the tactile output generated by the physical displacement will be interpreted by the user as a tactile sensation that corresponds to a perceived change in a physical characteristic of the device or component of the device. For example, movement of a touch-sensitive surface (e.g., a touch-sensitive display or trackpad) is optionally interpreted by the user as a "press click" or "release click" on a physical actuation button. In some cases, the user will feel a tactile sensation, such as a "press click" or "release click," even when the physical actuation button associated with the touch-sensitive surface that was physically pressed (e.g., displaced) by the user's movement does not move. As another example, even when the smoothness of the touch-sensitive surface does not change, movement of the touch-sensitive surface may optionally be interpreted or sensed by the user as "roughness" of the touch-sensitive surface. Although such interpretation of touch by the user will be limited by the user's individualized sensory perception, many sensory perceptions of touch are common to most users. Therefore, when a tactile output is described as corresponding to a specific sensory perception of a user (e.g., "press click," "release click," "roughness"), unless otherwise stated, the tactile output generated corresponds to a physical displacement of the device or a component thereof that would generate the sensory perception of a typical (or average) user. Providing tactile feedback to the user using tactile output enhances the operability of the device and makes the user-device interface more efficient (e.g., by helping the user provide appropriate input and reducing user errors when operating / interacting with the device), thereby further reducing power usage and extending the battery life of the device by enabling the user to use the device more quickly and efficiently.

[0164] In some embodiments, the tactile output pattern specifies characteristics of the tactile output, such as the amplitude of the tactile output, the shape of the motion waveform of the tactile output, the frequency of the tactile output, and / or the duration of the tactile output.

[0165] When a device (e.g., one or more tactile output generators that generate tactile outputs via movement of a movable mass) generates tactile outputs with different tactile output patterns, the tactile outputs can induce different tactile sensations to a user holding or touching the device. While a user's senses are based on their perception of the tactile outputs, most users will be able to discern changes in the waveform, frequency, and amplitude of the tactile outputs generated by the device. Therefore, the waveform, frequency, and amplitude can be adjusted to indicate to the user that different actions have been performed. Thus, tactile outputs with tactile output patterns designed, selected, and / or arranged to simulate the characteristics (e.g., size, material, weight, stiffness, smoothness, etc.); behavior (e.g., oscillation, displacement, acceleration, rotation, extension, etc.); and / or interaction (e.g., collision, adhesion, repulsion, attraction, friction, etc.) of objects in a given environment (e.g., a user interface including graphical features and objects, a simulated physical environment with virtual boundaries and virtual objects, a real physical environment with physical boundaries and physical objects, and / or any combination thereof) can, in some cases, provide helpful feedback to the user, reducing input errors and improving the user's efficiency in operating the device. In addition, tactile output is optionally generated to correspond to feedback that is unrelated to the simulated physical properties (such as input threshold or object selection). Such tactile output will provide helpful feedback to the user in some cases, which reduces input errors and improves the efficiency of the user's operation of the device.

[0166] In some embodiments, a tactile output with a suitable tactile output pattern serves as a prompt for an event of interest in the user interface or behind the screen in the device. Examples of events of interest include activation of an affordance (e.g., a real or virtual button or toggle switch) provided on the device or in the user interface, the success or failure of a requested operation, reaching or crossing a boundary in the user interface, entering a new state, switching input focus between objects, activating a new mode, reaching or crossing an input threshold, detecting or recognizing a type of input or gesture, and the like. In some embodiments, a tactile output is provided to serve as a warning or prompt for an upcoming event or result that would otherwise occur unless a change in direction or interrupt input is detected in a timely manner. Tactile output is also used in other contexts to enrich the user experience, improve the accessibility of the device for users with visual or motor difficulties or other accessibility needs, and / or improve the efficiency and functionality of the user interface and / or device. Optionally, the tactile output is compared with audio input and / or visual user interface changes, which further enhances the user's experience when the user interacts with the user interface and / or device, and facilitates better transmission of information about the state of the user interface and / or device, and reduces input errors and improves the efficiency of the user's operation on the device.

[0167] Figures 4C to 4EA set of sample tactile output patterns are provided that can be used, individually or in combination, as is or through one or more transformations (e.g., modulation, amplification, truncation, etc.) to generate suitable tactile feedback in various scenarios for various purposes (such as those described above and those described with respect to the user interfaces and methods discussed herein). This example of a control panel for tactile output shows how a set of three waveforms and eight frequencies can be used to generate an array of tactile output patterns. In addition to the tactile output patterns shown in the figure, each of these tactile output patterns is optionally adjusted in amplitude by changing the gain value of the tactile output pattern, as shown, for example, for Figures 4F to 4H 80Hz, FullTap 200Hz, MiniTap 80Hz, MiniTap 200Hz, MicroTap 80Hz, and MicroTap 200Hz, each of which is shown with a gain of 1.0, 0.75, 0.5, and 0.25. Figures 4F to 4H As shown, changing the gain of a tactile output pattern changes the amplitude of the pattern without changing the frequency of the pattern or changing the shape of the waveform. In some embodiments, changing the frequency of the tactile output pattern also results in a lower amplitude because some tactile output generators are limited by how much force can be applied to the movable mass, so the higher frequency movement of the mass is constrained to a lower amplitude to ensure that the acceleration required to generate the waveform does not require forces outside the operating force range of the tactile output generator (e.g., the peak amplitude of FullTap at 230 Hz, 270 Hz, and 300 Hz is lower than the amplitude of FullTap at 80 Hz, 100 Hz, 125 Hz, and 200 Hz).

[0168] Figures 4C to 4H The waveform of the tactile output pattern represents the tactile output pattern relative to the neutral position (e.g., x zero ) versus time, through which the movable mass passes to generate a tactile output having the tactile output pattern. For example, Figure 4C The first set of tactile output patterns shown (e.g., the "FullTap" tactile output pattern) each have a waveform that includes oscillations having two complete cycles (e.g., oscillations that start and end at a neutral position and pass through the neutral position three times). Figure 4D The second set of tactile output patterns shown (e.g., the "MiniTap" tactile output patterns) each have a waveform that includes an oscillation having one complete cycle (e.g., an oscillation that begins and ends at a neutral position and passes through the neutral position once). Figure 4EThe third set of tactile output patterns shown (e.g., "MicroTap" tactile output patterns) each have a waveform that includes an oscillation with half a complete cycle (e.g., an oscillation that begins and ends at a neutral position and does not pass through the neutral position). The waveforms of the tactile output patterns also include starting and ending buffers that represent gradual acceleration and deceleration of the movable mass at the beginning and end of the tactile output. Figures 4C to 4H The example waveforms shown include x and y representing the maximum and minimum extents of movement of the movable mass. min and x max For larger electronic devices with larger movable masses, the minimum and maximum degrees of movement of the mass may be larger or smaller. Figures 4C to 4H The examples shown describe movement of a mass in 1 dimension, but similar principles can also be applied to movement of a movable mass in two or three dimensions.

[0169] like Figures 4C to 4E As shown, each tactile output pattern also has a corresponding characteristic frequency, which affects the "pitch" of the tactile sensation felt by the user from the tactile output having that characteristic frequency. For continuous tactile output, the characteristic frequency represents the number of cycles (e.g., cycles per second) that the movable mass of the tactile output generator completes in a given time period. For discrete tactile output, a discrete output signal is generated (e.g., having 0.5, 1, or 2 cycles), and the characteristic frequency value specifies how fast the movable mass needs to move to generate a tactile output having that characteristic frequency. Figure 4C-4H As shown, for each type of tactile output (e.g., defined by a corresponding waveform, such as FullTap, MiniTap, or MicroTap), higher frequency values ​​correspond to faster movement of the movable mass and, therefore, generally, to shorter tactile output completion times (e.g., including the time required to complete the number of cycles of the discrete tactile output plus the start and end buffer times). For example, a FullTap with a characteristic frequency of 80 Hz takes longer to complete than a FullTap with a characteristic frequency of 100 Hz (e.g., in Figure 4F, 35.4ms vs. 28.3ms). In addition, for a given frequency, a tactile output with more cycles in its waveform at the corresponding frequency takes longer to complete than a tactile output with fewer cycles in its waveform at the same corresponding frequency. For example, a 150Hz FullTap takes longer to complete than a 150Hz MiniTap (e.g., 19.4ms vs. 12.8ms), and a 150Hz MiniTap takes longer to complete than a 150Hz MicroTap (e.g., 12.8ms vs. 9.4ms). However, for tactile output modes with different frequencies, this rule may not apply (e.g., a tactile output with more cycles but a higher frequency may take a shorter amount of time to complete than a tactile output with fewer cycles but a lower frequency, and vice versa). For example, at 300Hz, FullTap takes the same amount of time as MiniTap (e.g., 9.9ms).

[0170] like Figures 4C to 4E As shown, the tactile output pattern also has a characteristic amplitude, which affects the amount of energy contained in the tactile signal or the "intensity" of the tactile sensation that the user can feel through the tactile output having the characteristic amplitude. In some embodiments, the characteristic amplitude of the tactile output pattern refers to an absolute or normalized value representing the maximum displacement of the movable mass relative to the neutral position when generating the tactile output. In some embodiments, the characteristic amplitude of the tactile output pattern can be adjusted according to various conditions (e.g., customized based on user interface context and behavior) and / or preconfigured metrics (e.g., input-based metrics, and / or user interface-based metrics), such as by a fixed or dynamically determined gain factor (e.g., a value between 0 and 1). In some embodiments, an input-based metric (e.g., an intensity change metric or an input speed metric) measures a characteristic of the input during the period that triggers the generation of the tactile output (e.g., the rate of change of the characteristic intensity of the contact in a press input or the rate of movement of the contact on the touch-sensitive surface). In some embodiments, a user interface-based metric (e.g., a boundary-crossing velocity metric) measures a characteristic of a user interface element (e.g., the speed at which the element moves across a hidden or visible boundary in the user interface) during a user interface change that triggers generation of a tactile output. In some embodiments, a characteristic amplitude of the tactile output pattern can be "envelope" modulated, and the peaks of adjacent cycles can have different amplitudes, where one of the waveforms shown above is further modified by multiplying by an envelope parameter that changes over time (e.g., from 0 to 1) to gradually adjust the amplitude of a portion of the tactile output over time as the tactile output is generated.

[0171] Although Figures 4C to 4ESpecific frequencies, amplitudes, and waveforms are shown in the sample tactile output patterns for illustrative purposes, but tactile output patterns with other frequencies, amplitudes, and waveforms can also be used for similar purposes. For example, a waveform with between 0.5 and 4 cycles can be used. Other frequencies in the range of 60 Hz to 400 Hz can also be used.

[0172] It should be understood that device 100 is only one example of a portable multifunction device and that device 100 optionally has more or fewer components than shown, optionally combines two or more components, or optionally has a different configuration or arrangement of the components. Figure 1A The various components shown are implemented in hardware, software, or a combination of both, including one or more signal processing and / or application specific integrated circuits.

[0173] Memory 102 optionally includes high-speed random access memory and optionally includes non-volatile memory, such as one or more disk storage devices, flash memory devices, or other non-volatile solid-state memory devices. Memory controller 122 optionally controls access to memory 102 by other components of device 100.

[0174] The peripheral device interface 118 can be used to couple the input peripheral devices and output peripheral devices of the device to the CPU 120 and the memory 102. The one or more processors 120 run or execute various software programs and / or instruction sets stored in the memory 102 to perform various functions of the device 100 and process data. In some embodiments, the peripheral device interface 118, the CPU 120, and the memory controller 122 are optionally implemented on a single chip such as the chip 104. In some other embodiments, they are optionally implemented on separate chips.

[0175] RF (radio frequency) circuitry 108 receives and transmits RF signals, also known as electromagnetic signals.

However, the touch screen 112 displays visual output from the device 100, whereas a touch-sensitive trackpad does not provide visual output.

[0183] In some embodiments, the touch-sensitive display of the touch screen 112 is as described in the following applications: (1) U.S. patent application No. 11 / 381,313, entitled “Multipoint Touch Surface Controller,” filed on May 2, 2006; (2) U.S. patent application No. 10 / 840,862, entitled “Multipoint Touchscreen,” filed on May 6, 2004; (3) U.S. patent application No. 10 / 903,964, entitled “Gestures For Touch Sensitive Input Devices,” filed on July 30, 2004; (4) U.S. patent application No. 11 / 048,264, entitled “Gestures For Touch Sensitive Input Devices,” filed on January 31, 2005; (5) U.S. patent application No. 11 / 054,965, entitled “Mode-Based Graphical User Interfaces For Touch Sensitive Input Devices,” filed on January 18, 2005 (6) U.S. Patent Application No. 11 / 228,758, filed September 16, 2005, entitled “Virtual Input Device Placement On A Touch Screen User Interface”; (7) U.S. Patent Application No. 11 / 228,700, filed September 16, 2005, entitled “Operation Of A Computer With A Touch Screen Interface”; (8) U.S. Patent Application No. 11 / 228,737, filed September 16, 2005, entitled “Activating Virtual Keys Of A Touch-Screen Virtual Keyboard”; and (9) U.S. Patent Application No. 11 / 228,768, filed March 3, 2006, entitled “Multi-Functional Hand-Held All of these applications are incorporated herein by reference in their entirety.

[0184] The touch screen 112 optionally has a video resolution exceeding 100 dpi. In some embodiments, the touch screen has a video resolution of about 160 dpi. The user optionally uses any suitable object or appendage, such as a stylus, a finger, or the like, to contact the touch screen 112. In some embodiments, the user interface is designed to work primarily through finger-based contacts and gestures, which may not be as precise as stylus-based input due to the larger contact area of ​​a finger on the touch screen. In some embodiments, the device converts rough finger-based input into precise pointer / cursor positions or commands for performing the user's desired action.

[0185] In some embodiments, in addition to the touch screen, the device 100 optionally includes a touchpad (not shown) for activating or deactivating specific functions. In some embodiments, the touchpad is a touch-sensitive area of ​​the device that, unlike the touch screen, does not display visual output.

The optical sensor 164 receives light from the environment projected through one or more lenses and converts the light into data representing an image. In conjunction with the imaging module 143 (also called a camera module), the optical sensor 164 optionally captures still images or video. In some embodiments, the optical sensor is located on the rear of the device 100, facing away from the touch screen display 112 on the front of the device, enabling the touch screen display to be used as a viewfinder for still and / or video image acquisition. In some embodiments, the optical sensor is located on the front of the device, allowing the user to optionally capture an image of the user while viewing other video conference participants on the touch screen display for video conferencing. In some embodiments, the position of the optical sensor 164 can be changed by the user (e.g., by rotating the lens and sensor in the device housing), allowing a single optical sensor 164 to be used with the touch screen display for both video conferencing and still and / or video image acquisition.

[0188] Device 100 optionally also includes one or more contact intensity sensors 165 . Figure 1A A contact force sensor is shown coupled to force sensor controller 159 in I / O subsystem 106. Contact force sensor 165 optionally includes one or more piezoresistive strain gauges, capacitive force sensors, electrical force sensors, piezoelectric force sensors, optical force sensors, capacitive touch-sensitive surfaces, or other force sensors (e.g., sensors for measuring the force (or pressure) of a contact on a touch-sensitive surface). Contact force sensor 165 receives contact force information (e.g., pressure information or a surrogate for pressure information) from the environment. In some embodiments, at least one contact force sensor is juxtaposed with or adjacent to a touch-sensitive surface (e.g., touch-sensitive display system 112). In some embodiments, at least one contact force sensor is located on the back of device 100, opposite touch screen display 112 located on the front of device 100.

[0189] Device 100 optionally also includes one or more proximity sensors 166 . Figure 1AA proximity sensor 166 is shown coupled to the peripherals interface 118. Alternatively, the proximity sensor 166 is optionally coupled to the input controller 160 in the I / O subsystem 106. The proximity sensor 166 is optionally implemented as described in the following U.S. patent applications: No. 11 / 241,839, entitled “Proximity Detector In Handheld Device”; No. 11 / 240,788, entitled “Proximity Detector In Handheld Device”; No. 11 / 620,702, entitled “Using Ambient Light Sensor To Augment Proximity Sensor Output”; No. 11 / 586,862, entitled “Automated Response To And Sensing Of User Activity In Portable Devices”; and No. 11 / 638,251, entitled “Methods And Systems For Automatic Configuration Of Peripherals”, which are hereby incorporated by reference in their entirety. In some embodiments, when the multifunction device is placed near the user's ear (e.g., when the user is on a phone call), the proximity sensor turns off and disables the touch screen 112.

[0190] Device 100 optionally also includes one or more tactile output generators 167 . Figure 1AA tactile output generator is shown coupled to a tactile feedback controller 161 in the I / O subsystem 106. The tactile output generator 167 optionally includes one or more electroacoustic devices such as speakers or other audio components, and / or electromechanical devices that convert energy into linear motion such as motors, solenoids, electroactive polymers, piezoelectric actuators, electrostatic actuators, or other tactile output generating components (e.g., components that convert electrical signals into tactile outputs on the device). The contact force sensor 165 receives tactile feedback generation instructions from the tactile feedback module 133 and generates tactile outputs on the device 100 that can be felt by the user of the device 100. In some embodiments, at least one tactile output generator is juxtaposed or adjacent to a touch-sensitive surface (e.g., touch-sensitive display system 112) and optionally generates tactile outputs by moving the touch-sensitive surface vertically (e.g., inward / outward toward the surface of the device 100) or laterally (e.g., back and forth in the same plane as the surface of the device 100). In some embodiments, at least one tactile output generator sensor is located on the back of the device 100, opposite the touch screen display 112 located on the front of the device 100.

[0191] Device 100 optionally also includes one or more accelerometers 168 . Figure 1A An accelerometer 168 is shown coupled to the peripherals interface 118. Alternatively, the accelerometer 168 is optionally coupled to the input controller 160 in the I / O subsystem 106. The accelerometer 168 optionally implements as described in the following U.S. Patent Publication: U.S. Patent Publication 20050190059, entitled "Acceleration-based Theft Detection System for Portable Electronic Devices" and U.S. Patent Publication 20060017692, entitled "Methods And Apparatuses For Operating A Portable Device Based On An Accelerometer," both of which are incorporated herein by reference in their entirety. In some embodiments, information is displayed in a portrait view or a landscape view on the touch screen display based on analysis of data received from one or more accelerometers. Device 100 optionally includes a magnetometer (not shown) and a GPS (or GLONASS or other global navigation system) receiver (not shown) in addition to accelerometer 168 for obtaining information about the position and orientation (e.g., portrait or landscape) of device 100.

[0192] In some embodiments, the device 100 also includes one or more fingerprint sensors (or communicates with them). The one or more fingerprint sensors are coupled to the peripheral device interface 118. Alternatively, the one or more fingerprint sensors are optionally coupled to the input controller 160 in the I / O system 106. However, in a common embodiment, a secure dedicated computing hardware (e.g., one or more processors, memories, and / or communication buses) with additional security features is used to perform fingerprint recognition operations in order to enhance the security of the fingerprint information determined by the one or more fingerprint sensors. As used herein, a fingerprint sensor is a sensor that is capable of distinguishing fingerprint features of the ridges and valleys of the skin (sometimes called "minutive features"), such as those found on human fingers and toes. The fingerprint sensor can use any of a variety of technologies to distinguish fingerprint features, including but not limited to: optical fingerprint imaging, ultrasonic fingerprint imaging, active capacitance fingerprint imaging, and passive capacitance fingerprint imaging. In some embodiments, in addition to distinguishing fingerprint features in a fingerprint, the one or more fingerprint sensors are also capable of tracking the movement of fingerprint features over time, thereby determining / characterizing the movement of the fingerprint over time on the one or more fingerprint sensors. Although the one or more fingerprint sensors may be separate from the touch-sensitive surface (e.g., touch-sensitive display system 112), it should be understood that in some embodiments, the touch-sensitive surface (e.g., touch-sensitive display system 112) has a spatial resolution high enough to detect fingerprint features formed by individual fingerprint ridges and is used as a fingerprint sensor instead of or in addition to the one or more fingerprint sensors. In some embodiments, the device 100 includes a set of one or more orientation sensors for determining the orientation of a finger or hand on or adjacent to the device (e.g., the orientation of a finger over one or more fingerprint sensors). Additionally, in some embodiments, in addition to or in place of the fingerprint sensor, the set of one or more orientation sensors is used to detect rotation of a contact that is interacting with the device (e.g., in one or more of the methods described below, instead of using a fingerprint sensor to detect rotation of a fingerprint / contact, the set of one or more orientation sensors is used to detect rotation of a contact that includes a fingerprint, with or without detecting features of the fingerprint).

[0193] In some embodiments, the characteristics of the fingerprint and the comparison between the characteristics of the detected fingerprint and the characteristics of the stored fingerprint are performed by secure dedicated computing hardware (e.g., one or more processors, memory, and / or communication buses) separate from the processor 120 to improve the security of the fingerprint data generated, stored, and processed by the one or more fingerprint sensors. In some embodiments, the characteristics of the fingerprint and the comparison between the characteristics of the detected fingerprint and the characteristics of the registered fingerprint are performed by the processor 120 using a fingerprint analysis module.

[0194] In some embodiments, during the registration process, the device (e.g., a fingerprint analysis module or an independent security module in communication with the one or more fingerprint sensors) collects biometric information about one or more fingerprints of the user (e.g., identifying the relative positions of multiple nodes in the user's fingerprint). After the registration process has been completed, the biometric information is stored at the device (e.g., in a secure fingerprint module) for later use in authenticating the detected fingerprint. In some embodiments, the biometric information stored at the device excludes an image of the fingerprint and also excludes information from which the image of the fingerprint can be reconstructed, so that the image of the fingerprint does not inadvertently become available when the security of the device is compromised. In some embodiments, during the authentication process, the device (e.g., a fingerprint analysis module or an independent security module in communication with the one or more fingerprint sensors) determines whether the finger input detected by the one or more fingerprint sensors includes a fingerprint that matches a fingerprint previously registered by collecting biometric information about the fingerprint detected on the one or more fingerprint sensors (e.g., identifying the relative positions of multiple nodes in the fingerprint detected on the one or more fingerprint sensors) and compares the biometric information corresponding to the detected fingerprint with the biometric information corresponding to the registered fingerprint. In some embodiments, comparing the biometric information corresponding to the detected fingerprint with the biometric information corresponding to the registered fingerprint includes comparing the types and positions of nodes in the biometric information corresponding to the detected fingerprint with the types and positions of nodes in the biometric information corresponding to the registered fingerprint. However, the determination as to whether the finger input includes a fingerprint that matches a previously registered fingerprint registered using the device is optionally performed using any of a variety of well-known fingerprint authentication techniques to determine whether the detected fingerprint matches the registered fingerprint.

[0195] Device 100 optionally also includes one or more depth camera sensors 175 . Figure 1A A depth camera sensor is shown coupled to a depth camera controller 169 in the I / O subsystem 106. The depth camera sensor 175 receives data projected from the environment through the sensor. In conjunction with the imaging module 143 (also referred to as a camera module), the depth camera sensor 175 is optionally used to determine depth maps for different portions of the image captured by the imaging module 143. In some embodiments, the depth camera sensor is located on the front of the device 100 so that images of the user with depth information can be used for different functions of the device, such as video conferencing, capturing selfies with depth map data, and authenticating users of the device. In some embodiments, the position of the depth camera sensor 175 can be changed by the user (e.g., by rotating the lens and sensor in the device housing) so that the depth camera sensor 175 can be used with the touch screen display for both video conferencing and still image and / or video image acquisition.

[0196] In some embodiments, the software components stored in memory 102 include an operating system 126, a communication module (or instruction set) 128, a contact / motion module (or instruction set) 130, a graphics module (or instruction set) 132, a text input module (or instruction set) 134, a global positioning system (GPS) module (or instruction set) 135, and an application (or instruction set) 136. In addition, in some embodiments, memory 102 ( Figure 1A ) or memory 370( Figure 3 ) storage device / global internal state 157, such as Figure 1A and Figure 3 The device / global internal state 157 includes one or more of the following: an active application state indicating which applications, if any, are currently active; a display state indicating what applications, views, or other information occupy various areas of the touch screen display 112; a sensor state including information obtained from the device's various sensors and input control devices 116; and position information regarding the device's position and / or posture.

[0197] The operating system 126 (e.g., Darwin, RTXC, LINUX, UNIX, OS X, iOS, WINDOWS, or an embedded operating system such as VxWorks) includes various software components and / or drivers for controlling and managing general system tasks (e.g., memory management, storage device control, power management, etc.) and facilitating communication between various hardware components and software components.

[0198] The communication module 128 facilitates communication with other devices via one or more external ports 124 and also includes various software components for processing data received by the RF circuitry 108 and / or the external ports 124. The external ports 124 (e.g., Universal Serial Bus (USB), FireWire, etc.) are suitable for coupling directly to other devices or indirectly through a network (e.g., the Internet, wireless LAN, etc.). In some embodiments, the external ports are connected to (trademark of Apple Inc.) devices.

[0199] The contact / motion module 130 optionally detects contact with the touch screen 112 (in conjunction with the display controller 156) and other touch-sensitive devices (e.g., a trackpad or physical click wheel). The contact / motion module 130 includes various software components for performing various operations related to contact detection, such as determining whether contact has occurred (e.g., detecting a finger down event), determining the strength of the contact (e.g., the force or pressure of the contact, or a surrogate for the force or pressure of the contact), determining whether there has been movement of the contact and tracking the movement on the touch-sensitive surface (e.g., detecting one or more finger drag events), and determining whether the contact has ceased (e.g., detecting a finger lift event or contact break). The contact / motion module 130 receives contact data from the touch-sensitive surface. Determining the movement of a contact point optionally includes determining the rate (magnitude), velocity (magnitude and direction), and / or acceleration (change in magnitude and / or direction) of the contact point, the movement of which is represented by a series of contact data. These operations are optionally applied to a single point of contact (e.g., a single-finger contact) or multiple points of contact simultaneously (e.g., "multi-touch" / multiple-finger contact). In some embodiments, the contact / motion module 130 and display controller 156 detect contact on the touchpad.

[0200] In some embodiments, the contact / motion module 130 uses a set of one or more intensity thresholds to determine whether an action has been performed by a user (e.g., to determine whether a user has "clicked" an icon). In some embodiments, at least a subset of the intensity thresholds are determined based on software parameters (e.g., the intensity thresholds are not determined by the activation threshold of a particular physical actuator and can be adjusted without changing the physical hardware of the device 100). For example, a mouse "click" threshold for a touchpad or touchscreen can be set to any one of a large range of predefined thresholds without changing the touchpad or touchscreen display hardware. In addition, in some embodiments, a software setting is provided to the user of the device for adjusting one or more intensity thresholds in a set of intensity thresholds (e.g., by adjusting individual intensity thresholds and / or by utilizing a system-level click on an "intensity" parameter to adjust multiple intensity thresholds at once).

[0201] The contact / motion module 130 optionally detects gesture input from the user. Different gestures on the touch-sensitive surface have different contact patterns (e.g., different motions, timings, and / or intensities of the detected contacts). Thus, gestures are optionally detected by detecting specific contact patterns. For example, detecting a finger tap gesture includes detecting a finger press event and then detecting a finger lift (lift-off) event at the same location (or substantially the same location) as the finger press event (e.g., at the location of an icon). As another example, detecting a finger swipe gesture on the touch-sensitive surface includes detecting a finger press event, then detecting one or more finger drag events, and then detecting a finger lift (lift-off) event.

[0202] The graphics module 132 includes various known software components for rendering and displaying graphics on the touch screen 112 or other display, including components for changing the visual impact (e.g., brightness, transparency, saturation, contrast, or other visual attributes) of the displayed graphics. As used herein, the term "graphics" includes any object that can be displayed to a user, including, but not limited to, text, web pages, icons (such as user interface objects including soft keys), digital images, videos, animations, etc.

[0203] In some embodiments, the graphics module 132 stores data representing graphics to be used. Each graphic is optionally assigned a corresponding code. The graphics module 132 receives one or more codes specifying the graphics to be displayed from an application program or the like, along with coordinate data and other graphic attribute data, if necessary, and then generates screen image data for output to the display controller 156.

[0204] Haptic feedback module 133 includes various software components for generating instructions used by tactile output generator 167 to produce tactile output at one or more locations on device 100 in response to user interaction with device 100 .

[0205] Text input module 134, which is optionally a component of graphics module 132, provides a soft keyboard for entering text in various applications (e.g., contacts 137, email 140, IM 141, browser 147, and any other application requiring text input).

[0206] The GPS module 135 determines the location of the device and provides this information for use in various applications (e.g., to the phone 138 for use in location-based dialing; to the camera 143 as picture / video metadata; and to applications that provide location-based services, such as the weather widget, the local yellow pages widget, and the map / navigation widget).

Additional descriptions of online video applications can be found in U.S. provisional patent application 60 / 936,562, filed on June 20, 2007, entitled “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” and U.S. patent application 11 / 968,067, filed on December 31, 2007, entitled “Portable Multifunction Device, Method, and Graphical User Interface for Playing Online Videos,” the contents of which are hereby incorporated by reference in their entirety.

[0245] Each of the modules and applications described above corresponds to an executable instruction set for performing one or more of the functions described above and the methods described in this patent application (e.g., the computer-implemented methods and other information processing methods described herein). These modules (e.g., instruction sets) do not have to be implemented as separate software programs, processes, or modules, and thus various subsets of these modules are optionally combined or otherwise rearranged in various embodiments. For example, a video player module is optionally combined with a music player module into a single module (e.g., Figure 1A In some embodiments, the memory 102 optionally stores a subset of the above modules and data structures. In addition, the memory 102 optionally stores additional modules and data structures not described above.

[0246] In some embodiments, device 100 is a device that performs operations on a predefined set of functions on it solely through a touch screen and / or a touch pad. By using the touch screen and / or the touch pad as the primary input control device for operating device 100, the number of physical input control devices (e.g., push buttons, dials, etc.) on device 100 is optionally reduced.

[0247] A predefined set of functions that are exclusively performed through the touch screen and / or trackpad optionally includes navigation between user interfaces. In some embodiments, the trackpad, when touched by the user, navigates the device 100 from any user interface displayed on the device 100 to a main menu, home menu, or root menu. In such embodiments, the touchpad is used to implement a "menu button." In some other embodiments, the menu button is a physical push button or other physical input control device, rather than a touchpad.

[0248] Figure 1B is a block diagram illustrating exemplary components for event processing according to some embodiments. In some embodiments, memory 102 ( Figure 1A ) or memory 370( Figure 3 ) includes an event classifier 170 (e.g., in the operating system 126) and a corresponding application 136-1 (e.g., any one of the aforementioned applications 137 to 151, 155, 380 to 390).

[0249] Event classifier 170 receives event information and determines the application 136-1 and the application view 191 of application 136-1 to which the event information is to be delivered. Event classifier 170 includes an event monitor 171 and an event dispatcher module 174. In some embodiments, application 136-1 includes an application internal state 192 that indicates one or more current application views displayed on touch-sensitive display 112 when the application is active or executing. In some embodiments, device / global internal state 157 is used by event classifier 170 to determine which application(s) is currently active, and application internal state 192 is used by event classifier 170 to determine the application view 191 to which the event information is to be delivered.

[0250] In some embodiments, the application internal state 192 includes additional information, such as one or more of the following: resumption information to be used when the application 136-1 resumes execution, user interface state information indicating information being displayed by the application 136-1 or ready to be displayed by the application, a state queue for enabling the user to return to a previous state or view of the application 136-1, and a redo / undo queue of previous actions taken by the user.

[0251] Event monitor 171 receives event information from peripherals interface 118. The event information includes information about sub-events (e.g., a user touch on touch-sensitive display 112 as part of a multi-touch gesture). Peripherals interface 118 transmits information it receives from I / O subsystem 106 or sensors such as proximity sensor 166, accelerometer 168, and / or microphone 113 (via audio circuit 110). The information that peripherals interface 118 receives from I / O subsystem 106 includes information from touch-sensitive display 112 or a touch-sensitive surface.

[0252] In some embodiments, event monitor 171 sends requests to peripheral device interface 118 at predetermined intervals. In response, peripheral device interface 118 transmits event information. In other embodiments, peripheral device interface 118 transmits event information only when there is a significant event (e.g., receiving an input above a predetermined noise threshold and / or receiving an input for more than a predetermined duration).

[0253] In some embodiments, the event classifier 170 also includes a hit view determination module 172 and / or an active event identifier determination module 173.

[0254] When the touch-sensitive display 112 displays more than one view, the hit view determination module 172 provides software procedures for determining where within one or more views a sub-event has occurred. A view consists of controls and other elements that a user can see on the display.

[0255] Another aspect of the user interface associated with an application is a set of views, sometimes also referred to herein as application views or user interface windows, in which information is displayed and touch-based gestures occur. The application views (of the respective application) in which a touch is detected optionally correspond to programmatic levels within the application's programmatic or view hierarchy. For example, the lowest-level view in which a touch is detected is optionally referred to as a hit view, and the set of events recognized as correct input is optionally determined based at least in part on the hit view of the initial touch that started the touch-based gesture.

[0256] Hit view determination module 172 receives information related to sub-events of touch-based gestures. When an application has multiple views organized in a hierarchy, hit view determination module 172 identifies the hit view as the lowest view in the hierarchy where the sub-events should be processed. In most cases, the hit view is the lowest-level view in which the initiating sub-event (e.g., the first sub-event in a sequence of sub-events that form an event or potential event) occurs. Once a hit view is identified by hit view determination module 172, the hit view typically receives all sub-events related to the same touch or input source for which it was identified as the hit view.

[0257] Active event recognizer determination module 173 determines which view or views within the view hierarchy should receive a particular sequence of sub-events. In some embodiments, active event recognizer determination module 173 determines that only the hit view should receive a particular sequence of sub-events. In other embodiments, active event recognizer determination module 173 determines that all views that include the physical location of the sub-event are actively participating views, and therefore determines that all actively participating views should receive a particular sequence of sub-events. In other embodiments, even if a touch sub-event is completely confined to an area associated with one particular view, views higher in the hierarchy will still remain actively participating views.

[0258] Event dispatcher module 174 dispatches event information to event recognizers (e.g., event recognizer 180). In embodiments that include active event recognizer determination module 173, event dispatcher module 174 delivers the event information to the event recognizer determined by active event recognizer determination module 173. In some embodiments, event dispatcher module 174 stores the event information in an event queue, which is retrieved by corresponding event receiver 182.

[0259] In some embodiments, operating system 126 includes event classifier 170. Alternatively, application 136-1 includes event classifier 170. In yet another embodiment, event classifier 170 is a standalone module or part of another module stored in memory 102, such as contact / motion module 130.

[0260] In some embodiments, application 136-1 includes multiple event handlers 190 and one or more application views 191, each of which includes instructions for handling touch events that occur within a corresponding view of the application's user interface. Each application view 191 of application 136-1 includes one or more event recognizers 180. Typically, the corresponding application view 191 includes multiple event recognizers 180. In other embodiments, one or more of event recognizers 180 are part of a separate module, such as a user interface toolkit (not shown) or a higher-level object from which application 136-1 inherits methods and other properties. In some embodiments, the corresponding event handler 190 includes one or more of the following: a data updater 176, an object updater 177, a GUI updater 178, and / or event data 179 received from an event classifier 170. Event handler 190 optionally utilizes or calls data updater 176, object updater 177, or GUI updater 178 to update the application internal state 192. Alternatively, one or more of the application views in application view 191 include one or more corresponding event handlers 190. Additionally, in some embodiments, one or more of data updater 176, object updater 177, and GUI updater 178 are included in the corresponding application view 191.

[0261] A corresponding event identifier 180 receives event information (e.g., event data 179) from event classifier 170 and identifies an event from the event information. Event identifier 180 includes an event receiver 182 and an event comparator 184. In some embodiments, event identifier 180 also includes metadata 183 and at least a subset of event delivery instructions 188 (which optionally include sub-event delivery instructions).

[0262] The event receiver 182 receives event information from the event classifier 170. The event information includes information about sub-events such as touches or touch movements. Depending on the sub-event, the event information also includes additional information, such as the location of the sub-event. When the sub-event involves the movement of a touch, the event information optionally also includes the rate and direction of the sub-event. In some embodiments, the event includes the device rotating from one orientation to another (e.g., from a portrait orientation to a landscape orientation, or vice versa), and the event information includes corresponding information about the current orientation of the device (also referred to as the device posture).

[0263] The event comparator 184 compares the event information with predefined event or sub-event definitions and determines the event or sub-event based on the comparison, or determines or updates the state of the event or sub-event. In some embodiments, the event comparator 184 includes an event definition 186. The event definition 186 includes the definition of an event (e.g., a predefined sequence of sub-events), such as event 1 (187-1), event 2 (187-2), and other events. In some embodiments, the sub-events in event (187) include, for example, touch start, touch end, touch move, touch cancel, and multi-touch. In one example, the definition of event 1 (187-1) is a double-click on a displayed object. For example, a double-click includes a first touch (touch start) of a predetermined duration on the displayed object, a first lift-off (touch end) of a predetermined duration, a second touch (touch start) of a predetermined duration on the displayed object, and a second lift-off (touch end) of a predetermined duration. In another example, the definition of event 2 (187-2) is a drag on a displayed object. For example, a drag includes a touch (or contact) of a predetermined duration on a displayed object, movement of the touch on the touch-sensitive display 112, and lift-off of the touch (touch end). In some embodiments, the event also includes information for one or more associated event handlers 190.

[0264] In some embodiments, event definition 187 includes definitions of events for corresponding user interface objects. In some embodiments, event comparator 184 performs a hit test to determine which user interface object is associated with a sub-event. For example, in an application view displaying three user interface objects on touch display 112, when a touch is detected on touch-sensitive display 112, event comparator 184 performs a hit test to determine which of the three user interface objects is associated with the touch (sub-event). If each displayed object is associated with a corresponding event handler 190, the event comparator uses the result of the hit test to determine which event handler 190 should be activated. For example, event comparator 184 selects an event handler that is associated with the sub-event and the object that triggered the hit test.

[0265] In some embodiments, the definition of the corresponding event 187 also includes a delay action that delays the delivery of the event information until it has been determined whether the sub-event sequence does or does not correspond to the event type of the event identifier.

[0266] When a corresponding event recognizer 180 determines that a sequence of sub-events does not match any event in event definitions 186, the corresponding event recognizer 180 enters the event impossible, event failed, or event ended state, after which subsequent sub-events of the touch-based gesture are ignored. In this case, other event recognizers (if any) that remain active for the hit view continue to track and process sub-events of the ongoing touch-based gesture.

[0267] In some embodiments, the corresponding event recognizers 180 include metadata 183 having configurable properties, flags, and / or lists that indicate how the event delivery system should perform sub-event delivery for actively participating event recognizers. In some embodiments, metadata 183 includes configurable properties, flags, and / or lists that indicate how event recognizers interact or can interact with each other. In some embodiments, metadata 183 includes configurable properties, flags, and / or lists that indicate whether sub-events are delivered to different levels in a view or programmatic hierarchy.

[0268] In some embodiments, when one or more specific sub-events of an event are identified, the corresponding event recognizer 180 activates an event handler 190 associated with the event. In some embodiments, the corresponding event recognizer 180 delivers event information associated with the event to the event handler 190. Activating an event handler 190 is different from sending (and deferred sending) sub-events to the corresponding hit view. In some embodiments, the event recognizer 180 throws a flag associated with the identified event, and the event handler 190 associated with the flag receives the flag and performs a predefined process.

[0269] In some embodiments, event delivery instructions 188 include sub-event delivery instructions that deliver event information about a sub-event without activating an event handler. Instead, the sub-event delivery instructions deliver the event information to an event handler associated with the sub-event sequence or to an actively participating view. The event handler associated with the sub-event sequence or with the actively participating view receives the event information and performs a predetermined process.

[0270] In some embodiments, data updater 176 creates and updates data used in application 136-1. For example, data updater 176 updates phone numbers used in contact module 137 or stores video files used in video player module. In some embodiments, object updater 177 creates and updates objects used in application 136-1. For example, object updater 177 creates new user interface objects or updates the location of user interface objects. GUI updater 178 updates the GUI. For example, GUI updater 178 prepares display information and sends the display information to graphics module 132 for display on a touch-sensitive display.

[0271] In some embodiments, event handler 190 includes or has access to data updater 176, object updater 177, and GUI updater 178. In some embodiments, data updater 176, object updater 177, and GUI updater 178 are included in a single module of the corresponding application 136-1 or application view 191. In other embodiments, they are included in two or more software modules.

[0272] Figure 1C is a block diagram illustrating a tactile output module according to some embodiments. In some embodiments, the I / O subsystem 106 (e.g., the tactile feedback controller 161 ( Figure 1A ) and / or other input controller 160 ( Figure 1A ))include Figure 1C At least some of the example components shown. In some embodiments, the peripheral device interface 118 includes Figure 1C At least some of the example components shown.

[0273] In some embodiments, the tactile output module includes a tactile feedback module 133. In some embodiments, the tactile feedback module 133 aggregates and combines tactile output of user interface feedback from software applications on the electronic device (e.g., feedback in response to user input corresponding to the displayed user interface and prompts and other notifications indicating the execution of operations or the occurrence of events in the user interface of the electronic device). The tactile feedback module 133 includes one or more of a waveform module 123 (for providing waveforms for generating tactile output), a mixer 125 (for mixing waveforms, such as waveforms in different channels), a compressor 127 (for reducing or compressing the dynamic range of the waveform), a low-pass filter 129 (for filtering out high-frequency signal components in the waveform), and a thermal controller 131 (for adjusting the waveform according to thermal conditions). In some embodiments, the tactile feedback module 133 is included in the tactile feedback controller 161 ( Figure 1AIn some embodiments, a separate unit of the tactile feedback module 133 (or a separate specific implementation of the tactile feedback module 133) is also included in the audio controller (e.g., Figure 1A In some embodiments, a single haptic feedback module 133 is used to generate the audio signal and to generate the waveform of the tactile output.

[0274] In some embodiments, the haptic feedback module 133 also includes a trigger module 121 (e.g., a software application, operating system, or other software module that determines that a tactile output is to be generated and initiates a process for generating the corresponding tactile output). In some embodiments, the trigger module 121 generates a trigger signal that is used to initiate (e.g., by the waveform module 123) the generation of a waveform. For example, the trigger module 121 generates the trigger signal based on a preset timing standard. In some embodiments, the trigger module 121 receives the trigger signal from outside the haptic feedback module 133 (e.g., in some embodiments, the haptic feedback module 133 receives the trigger signal from a hardware input processing module 146 located outside the haptic feedback module 133) and relays the trigger signal to other components within the haptic feedback module 133 (e.g., the waveform module 123) or a software application that triggers an operation (e.g., using the trigger module 121) based on activation of a user interface element (e.g., an application icon or an enable representation within an application) or a hardware input device (e.g., a home button or an intensity-sensitive input surface, such as an intensity-sensitive touch screen). In some embodiments, the trigger module 121 also (e.g., from Figure 1A and Figure 3 In some embodiments, the trigger module 121 responds to the tactile feedback module 133 (or the trigger module 121 in the tactile feedback module 133) (e.g., Figure 1A and Figure 3 The tactile feedback module 133 in receives the tactile feedback instruction and generates a trigger signal.

[0275] Waveform module 123 receives as input a trigger signal (e.g., from trigger module 121) and, in response to receiving the trigger signal, provides a waveform for generating one or more tactile outputs (e.g., a waveform selected from a predefined set of waveforms designated for use by waveform module 123, such as those described below with reference to Figures 4C to 4D waveforms described in more detail).

[0276] The mixer 125 receives waveforms as input (e.g., from the waveform module 123) and mixes the waveforms together. For example, when the mixer 125 receives two or more waveforms (e.g., a first waveform in a first channel and a second waveform in a second channel that at least partially overlaps with the first waveform), the mixer 125 outputs a combined waveform corresponding to the sum of the two or more waveforms. In some embodiments, the mixer 125 also modifies one or more of the two or more waveforms to emphasize a particular waveform relative to the rest of the two or more waveforms (e.g., by increasing the scale of the particular waveform and / or reducing the scale of the other waveforms in the waveforms). In some cases, the mixer 125 selects one or more waveforms to remove from the combined waveform (e.g., when there are waveforms from more than three sources that have been requested to be output simultaneously by the tactile output generator 167, the waveform from the oldest source is discarded).

[0277] Compressor 127 receives waveforms (e.g., combined waveforms from mixer 125) as input and modifies these waveforms. In some embodiments, compressor 127 reduces these waveforms (e.g., based on the tactile output generator 167 ( Figure 1A ) or 357( Figure 3 ) such that the tactile output corresponding to these waveforms is reduced. In some embodiments, compressor 127 limits the waveforms, such as by imposing a predefined maximum amplitude on the waveforms. For example, compressor 127 reduces the amplitude of the waveform portion that exceeds a predefined amplitude threshold, while maintaining the amplitude of the waveform portion that does not exceed the predefined amplitude threshold. In some embodiments, compressor 127 reduces the dynamic range of the waveforms. In some embodiments, compressor 127 dynamically reduces the dynamic range of the waveforms such that the combined waveform remains within the performance specifications of tactile output generator 167 (e.g., force and / or movable mass displacement limits).

[0278] Low-pass filter 129 receives a waveform (e.g., a compressed waveform from compressor 127) as input and filters (e.g., smoothes) the waveform (e.g., removes or reduces high-frequency signal components in the waveform). For example, in some cases, compressor 127 may include extraneous signals (e.g., high-frequency signal components) in the compressed waveform that interfere with generating tactile output and / or exceed the performance specifications of tactile output generator 167 when generating tactile output based on the compressed waveform. Low-pass filter 129 reduces or removes such extraneous signals in the waveform.

[0279] Thermal controller 131 receives a waveform (e.g., a filtered waveform from low-pass filter 129) as input and adjusts the waveform based on the thermal condition of device 100 (e.g., based on an internal temperature detected within device 100, such as the temperature of haptic feedback controller 161, and / or an external temperature detected by device 100). For example, in some cases, the output of haptic feedback controller 161 varies based on temperature (e.g., in response to receiving the same waveform, haptic feedback controller 161 generates a first tactile output when haptic feedback controller 161 is at a first temperature and generates a second tactile output when haptic feedback controller 161 is at a second temperature different from the first temperature). For example, the magnitude (or amplitude) of the tactile output may vary based on temperature. To reduce the effects of temperature changes, the waveform is modified (e.g., the amplitude of the waveform is increased or decreased based on temperature).

[0280] In some embodiments, the tactile feedback module 133 (e.g., trigger module 121) is coupled to the hardware input processing module 146. In some embodiments, Figure 1A Other input controllers 160 in the embodiment include a hardware input processing module 146. In some embodiments, the hardware input processing module 146 receives input from a hardware input device 145 (e.g., Figure 1A In some embodiments, the hardware input device 145 is any input device described herein, such as a touch-sensitive display system 112 ( Figure 1A )、Keyboard / Mouse 350( Figure 3 )、Touchpad 355( Figure 3 ), other input or control devices 116 ( Figure 1A ) or a strength-sensitive home button. In some embodiments, the hardware input device 145 consists of a strength-sensitive home button rather than a touch-sensitive display system 112 ( Figure 1A )、Keyboard / Mouse 350( Figure 3 ) or touchpad 355( Figure 3 ). In some embodiments, in response to input from a hardware input device 145 (e.g., an intensity-sensitive home button or a touch screen), the hardware input processing module 146 provides one or more trigger signals to the tactile feedback module 133 to indicate that user input that meets predefined input criteria has been detected, such as input corresponding to a "click" (e.g., a "press click" or a "release click") on the home button. In some embodiments, the tactile feedback module 133 provides a waveform corresponding to a home button "click" in response to input corresponding to a home button "click", thereby simulating the tactile feedback of pressing a physical home button.

[0281] In some embodiments, the tactile output module includes a tactile feedback controller 161 (e.g., Figure 1A 145 ). In some embodiments, the tactile feedback controller 161 is coupled to a plurality of tactile output generators and selects one or more tactile output generators from the plurality of tactile output generators and sends a waveform to the selected one or more tactile output generators for generating a tactile output. In some embodiments, the tactile feedback controller 161 coordinates a tactile output request corresponding to activation of the hardware input device 145 and a tactile output request corresponding to a software event (e.g., a tactile output request from the tactile feedback module 133), and modifies one or more of the two or more waveforms to emphasize a particular waveform relative to the remaining waveforms of the two or more waveforms (e.g., by increasing the scale of the particular waveform and / or reducing the scale of the remaining waveforms of the waveforms to prioritize the tactile output corresponding to activation of the hardware input device 145 over the tactile output corresponding to the software event).

[0282] In some embodiments, as Figure 1C As shown, the output of tactile feedback controller 161 is coupled to the audio circuitry of device 100 (e.g., Figure 1A 100 ) and provides the audio signal to the audio circuit of device 100. In some embodiments, haptic feedback controller 161 provides both a waveform for generating a tactile output and an audio signal for providing an audio output along with generating the tactile output. In some embodiments, haptic feedback controller 161 modifies the audio signal and / or the waveform (for generating the tactile output) so that the audio output and the tactile output are synchronized (e.g., by delaying the audio signal and / or the waveform). In some embodiments, haptic feedback controller 161 includes a digital-to-analog converter for converting the digital waveform into an analog signal, which is received by amplifier 163 and / or tactile output generator 167.

[0283] In some embodiments, the tactile output module includes an amplifier 163. In some embodiments, the amplifier 163 receives a waveform (e.g., from the tactile feedback controller 161), amplifies the waveform, and then sends the amplified waveform to the tactile output generator 167 (e.g., the tactile output generator 167 ( Figure 1A ) or 357( Figure 3)). For example, amplifier 163 amplifies the received waveform to a signal level that meets the physical specifications of tactile output generator 167 (e.g., to a voltage and / or current required by tactile output generator 167 to generate a tactile output such that the signal sent to tactile output generator 167 generates a tactile output corresponding to the waveform received from haptic feedback controller 161) and sends the amplified waveform to tactile output generator 167. In response, tactile output generator 167 generates a tactile output (e.g., by displacing the movable mass back and forth in one or more dimensions relative to the neutral position of the movable mass).

[0284] In some embodiments, the tactile output module includes a sensor 169 coupled to the tactile output generator 167. The sensor 169 detects the state or state change (e.g., mechanical position, physical displacement, and / or movement) of the tactile output generator 167 or one or more components of the tactile output generator 167 (e.g., one or more moving components for generating a tactile output, such as a membrane). In some embodiments, the sensor 169 is a magnetic field sensor (e.g., a Hall effect sensor) or other displacement and / or motion sensor. In some embodiments, the sensor 169 provides information (e.g., the position, displacement, and / or movement of one or more components in the tactile output generator 167) to the tactile feedback controller 161, and, based on the information about the state of the tactile output generator 167 provided by the sensor 169, the tactile feedback controller 161 adjusts the waveform output from the tactile feedback controller 161 (e.g., the waveform optionally sent to the tactile output generator 167 via the amplifier 163).

[0285] It should be understood that the above discussion of event handling for user touches on a touch-sensitive display also applies to other forms of user input utilizing input devices to operate the multifunction device 100, and not all user input is initiated on a touch screen. For example, mouse movement and mouse button presses, optionally in conjunction with single or multiple keyboard presses or holddowns; contact movement on a trackpad, such as taps, drags, scrolls, etc.; stylus input; movement of the device; spoken commands; detected eye movement; biometric input; and / or any combination thereof, are optionally used as input corresponding to sub-events defining the event to be recognized.

[0286] Figure 2A portable multifunction device 100 with a touch screen 112 is shown according to some embodiments. The touch screen optionally displays one or more graphics within a user interface (UI) 200. In this embodiment, and in other embodiments described below, a user can select one or more of the graphics by, for example, making gestures on the graphics using one or more fingers 202 (not drawn to scale in the figures) or using one or more styluses 203 (not drawn to scale in the figures). In some embodiments, selection of the one or more graphics occurs when the user breaks contact with the one or more graphics. In some embodiments, the gesture optionally includes one or more taps, one or more swipes (from left to right, from right to left, up and / or down), and / or rolling of a finger that has made contact with the device 100 (from right to left, from left to right, up and / or down). In some implementations or in some cases, inadvertent contact with a graphic does not select the graphic. For example, a swipe gesture that sweeps over an application icon optionally does not select the corresponding application when the gesture corresponding to selection is a tap.

[0287] The device 100 optionally also includes one or more physical buttons, such as a "home" or menu button 204. As previously described, the menu button 204 is optionally used to navigate to any application 136 in a set of applications that are optionally executed on the device 100. Alternatively, in some embodiments, the menu button is implemented as a soft key in a GUI displayed on the touch screen 112.

[0288] In some embodiments, the device 100 includes a touch screen 112, a menu button 204, a push button 206 for turning the device on / off and for locking the device, one or more volume adjustment buttons 208, a subscriber identity module (SIM) card slot 210, a headset jack 212, and a docking / charging external port 124. The push button 206 is optionally used to turn the device on / off by pressing the button and holding it in the depressed state for a predefined time interval; to lock the device by pressing the button and releasing it before the predefined time interval has elapsed; and / or to unlock the device or initiate an unlocking process. In an alternative embodiment, the device 100 also accepts speech input for activating or deactivating certain functions via the microphone 113. The device 100 also optionally includes one or more contact force sensors 165 for detecting the intensity of contact on the touch screen 112, and / or one or more tactile output generators 167 for generating tactile output for the user of the device 100.

[0289] Figure 33 is a block diagram of an exemplary multifunction device with a display and a touch-sensitive surface according to some embodiments. The device 300 does not have to be portable. In some embodiments, the device 300 is a laptop computer, a desktop computer, a tablet computer, a multimedia player device, a navigation device, an educational device (such as a children's learning toy), a gaming system, or a control device (e.g., a home controller or an industrial controller). The device 300 typically includes one or more processing units (CPUs) 310, one or more network or other communication interfaces 360, a memory 370, and one or more communication buses 320 for interconnecting these components. The communication bus 320 optionally includes circuits (sometimes referred to as a chipset) that interconnect system components and control communications between system components. The device 300 includes an input / output (I / O) interface 330 having a display 340, which is typically a touch screen display. The I / O interface 330 also optionally includes a keyboard and / or mouse (or other pointing device) 350 and a touchpad 355, a tactile output generator 357 for generating tactile output on the device 300 (e.g., similar to the above referenced devices). Figure 1A The tactile output generator 167 described above), sensor 359 (e.g., optical sensor, acceleration sensor, proximity sensor, touch sensor and / or contact intensity sensor (similar to the above reference Figure 1A The memory 370 includes high-speed random access memory, such as DRAM, SRAM, DDR RAM, or other random access solid-state memory devices; and optionally includes non-volatile memory, such as one or more magnetic disk storage devices, optical disk storage devices, flash memory devices, or other non-volatile solid-state storage devices. The memory 370 optionally includes one or more storage devices located remotely from the CPU 310. In some embodiments, the memory 370 stores data related to the portable multifunction device 100 ( Figure 1A ) or a subset thereof. In addition, memory 370 optionally stores additional programs, modules, and data structures not present in memory 102 of portable multifunction device 100. For example, memory 370 of device 300 optionally stores a drawing module 380, a presentation module 382, ​​a word processing module 384, a website creation module 386, a disk editing module 388, and / or a spreadsheet module 390, while portable multifunction device 100( Figure 1A )'s memory 102 optionally does not store these modules.

[0290] Figure 3Each element in the above-mentioned elements in is optionally stored in one or more memory devices of the memory device mentioned previously.Each module in the above-mentioned modules corresponds to the instruction set for performing the above-mentioned functions.Above-mentioned modules or programs (for example, instruction set) need not be implemented as independent software programs, processes or modules, and therefore the various subsets of these modules are optionally combined or otherwise rearranged in various embodiments.In some embodiments, memory 370 optionally stores the subset of above-mentioned modules and data structure.In addition, memory 370 optionally stores additional modules and data structure not described above.

[0291] Attention is now turned to an embodiment of a user interface, optionally implemented on, for example, portable multifunction device 100 .

[0292] Figure 4A An exemplary user interface is shown for a menu of applications on portable multifunction device 100 according to some embodiments. A similar user interface is optionally implemented on device 300. In some embodiments, user interface 400 includes the following elements, or a subset or superset thereof:

[0293] One or more signal strength indicators 402 of one or more wireless communications, such as cellular signals and Wi-Fi signals;

[0294] Time 404;

[0295] Bluetooth indicator 405;

[0296] Battery status indicator 406;

[0297] A tray 408 with icons for commonly used applications, such as:

[0298] o an icon 416 of the phone module 138 labeled “Phone,” which optionally includes an indicator 414 of the number of missed calls or voice messages;

[0299] o an icon 418 of the email client module 140 labeled “Mail,” which optionally includes an indicator 410 of the number of unread emails;

[0300] o An icon 420 labeled "Browser" of the browser module 147; and

[0301] o an icon 422 labeled “iPod” for the video and music player module 152 (also referred to as the iPod (trademark of Apple Inc.) module 152); and

[0302] Icons for other apps, such as:

[0303] o Icon 424 of the IM module 141 labeled “Messages”;

[0304] o Icon 426 labeled “Calendar” of calendar module 148;

[0305] o Icon 428 labeled “Photos” of the image management module 144;

[0306] o an icon 430 labeled “Camera” of the camera module 143;

[0307] o Icon 432 labeled “Online Video” of the online video module 155;

[0308] o Icon 434 labeled "Stock Market" of the Stock Market widget 149-2;

[0309] o an icon 436 labeled “Map” of the map module 154;

[0310] o Icon 438 labeled “Weather” of the Weather widget 149-1;

[0311] o Icon 440 labeled “Clock” of the Alarm Clock widget 149-4;

[0312] o an icon 442 labeled “Fitness Support” of the fitness support module 142;

[0313] o An icon 444 of the notepad module 153 labeled "Notepad"; and

[0314] o An icon 446 labeled “Settings” for a settings application or module that provides access to settings for the device 100 and its various applications 136.

[0315] It should be pointed out that Figure 4A The icon labels shown are exemplary only. For example, icon 422 for video and music player module 152 is labeled "Music" or "Music Player." Other labels are optionally used for various application icons. In some embodiments, the label of a respective application icon includes the name of the application corresponding to the respective application icon. In some embodiments, the label of a particular application icon is different from the name of the application corresponding to the particular application icon.

[0316] Figure 4B A touch-sensitive surface 451 (eg, touch screen display 112) is shown having a touch-sensitive surface 451 (eg, touch screen display 112) that is separate from a display 450 (eg, touch screen display 112). Figure 3 tablet or trackpad 355) of the device (e.g., Figure 3Device 300 also optionally includes one or more contact intensity sensors (e.g., one or more of sensors 359) for detecting intensity of contacts on touch-sensitive surface 451 and / or one or more tactile output generators 357 for generating tactile output for a user of device 300.

[0317] Although some of the examples below will be given with reference to input on a touch screen display 112 (where the touch-sensitive surface and display are combined), in some embodiments, the device detects input on a touch-sensitive surface that is separate from the display, such as Figure 4B In some embodiments, the touch-sensitive surface (e.g., Figure 4B 451) has a main axis (e.g., Figure 4B 453) corresponding to the main axis (for example, Figure 4B According to these embodiments, the device detects a position corresponding to a corresponding position on the display (e.g., Figure 4B , 460 corresponds to 468 and 462 corresponds to 470 ) at contact with touch-sensitive surface 451 (e.g., Figure 4B 460 and 462 in FIG. 4 ). Thus, on a touch-sensitive surface (e.g., Figure 4B 451) and the display of the multi-function device ( Figure 4B When the user interface 450 in FIG. 1 is separated, the user input detected by the device on the touch-sensitive surface (e.g., contacts 460 and 462 and their movement) is used by the device to manipulate the user interface on the display. It should be understood that similar methods are optionally used for other user interfaces described herein.

[0318] In addition, although the following examples are primarily given with reference to finger inputs (e.g., finger contacts, single-finger tap gestures, finger swipe gestures), it should be understood that in some embodiments, one or more of these finger inputs are replaced by input from another input device (e.g., mouse-based input or stylus input). For example, a swipe gesture is optionally replaced by a mouse click (e.g., instead of contact), followed by movement of the cursor along the path of the swipe (e.g., instead of movement of the contact). For another example, a tap gesture is optionally replaced by a mouse click when the cursor is over the location of the tap gesture (e.g., instead of detecting the contact, followed by ceasing to detect the contact). Similarly, when multiple user inputs are detected simultaneously, it should be understood that multiple computer mice are optionally used simultaneously, or mice and finger contacts are optionally used simultaneously.

[0319] Figure 5AAn exemplary personal electronic device 500 is shown. The device 500 includes a body 502. In some embodiments, the device 500 may include a body 502 relative to the devices 100 and 300 (e.g., Figures 1A to 4B ) some or all of the features described in . In some embodiments, device 500 has a touch-sensitive display screen 504, referred to hereinafter as touch screen 504. Alternatively or in addition to touch screen 504, device 500 also has a display and a touch-sensitive surface. As with devices 100 and 300, in some embodiments, touch screen 504 (or touch-sensitive surface) optionally includes one or more intensity sensors for detecting the intensity of applied contact (e.g., touch). The one or more intensity sensors of touch screen 504 (or touch-sensitive surface) can provide output data representing the intensity of the touch. The user interface of device 500 can respond to touches based on their intensity, which means that touches of different intensities can invoke different user interface operations on device 500.

[0320] Exemplary techniques for detecting and processing touch intensity are found, for example, in the following related patent applications: International Patent Application Serial No. PCT / US2013 / 040061, entitled “Device, Method, and Graphical User Interface for Displaying User Interface Objects Corresponding to an Application,” filed on May 8, 2013, published as WIPO Patent Publication No. WO / 2013 / 169849; and International Patent Application Serial No. PCT / US2013 / 069483, entitled “Device, Method, and Graphical User Interface for Transitioning Between Touch Input to Display Output Relationships,” filed on November 11, 2013, published as WIPO Patent Publication No. WO / 2014 / 105276, each of which is hereby incorporated by reference in its entirety.

[0321] In some embodiments, the device 500 has one or more input mechanisms 506 and 508. Input mechanisms 506 and 508 (if included) can be physical. Examples of physical input mechanisms include push buttons and rotatable mechanisms. In some embodiments, the device 500 has one or more attachment mechanisms. Such attachment mechanisms (if included) can allow the device 500 to be attached to, for example, hats, glasses, earrings, necklaces, shirts, jackets, bracelets, watchbands, bracelets, pants, belts, shoes, wallets, backpacks, etc. These attachment mechanisms allow the user to wear the device 500.

[0322] Figure 5B An exemplary personal electronic device 500 is shown. In some embodiments, the device 500 may include a Figure 1A 、 Figure 1B and Figure 3 Some or all of the components described. Device 500 has a bus 512 that operatively couples an I / O portion 514 to one or more computer processors 516 and a memory 518. The I / O portion 514 can be connected to a display 504, which can have a touch-sensitive component 522 and optionally a strength sensor 524 (e.g., a contact strength sensor). In addition, the I / O portion 514 can be connected to a communication unit 530 for receiving application and operating system data using Wi-Fi, Bluetooth, near-field communication (NFC), cellular, and / or other wireless communication technologies. Device 500 may include input mechanisms 506 and / or 508. For example, the input mechanism 506 is optionally a rotatable input device or a depressible input device and a rotatable input device. In some examples, the input mechanism 508 is optionally a button.

[0323] In some examples, input mechanism 508 is optionally a microphone. Personal electronic device 500 optionally includes various sensors, such as a GPS sensor 532, an accelerometer 534, an orientation sensor 540 (e.g., a compass), a gyroscope 536, a motion sensor 538, and / or combinations thereof, all of which are operatively connected to I / O portion 514.

[0324] The memory 518 of the personal electronic device 500 may include one or more non-transitory computer-readable storage media for storing computer-executable instructions that, when executed by one or more computer processors 516, may cause the computer processors to perform the following techniques, including process 800 ( FIG. 8 ), process 1000 ( FIG. 10 ), process 1200 ( FIG. 12 ), process 1400 ( FIG. 14 ), process 1600 ( FIG. 16 ), process 1800 ( FIG. 18 ), process 2000 ( FIG. 20 ), process 2200 ( FIG. 22 ), process 2500 ( FIG. 25 ), process 2700 ( FIG. 27 ), process 2900 ( FIG. 29 ), process 3100 ( FIG. 31 ), process 3300 ( FIG. 32 ), process 3400 ( FIG. 33 ), process 3500 ( FIG. 34 ), process 3600 ( FIG. 35 ), process 3700 ( FIG. 37 ), process 3800 ( FIG. 38 ), process 3900 ( FIG. 39 ), process 4000 ( FIG. 40 ), process 4100 ( FIG. 41 ), process 4200 ( FIG. 42 ), process 4300 ( FIG. 44 ), process 4400 ( FIG. 45 ), process 4500 ( FIG. 46 ), process 4600 ( FIG. 47 ), process 4700 ( FIG. 48 ), process 4800 ( FIG. 49 ), process 4900 ( FIG. 50 ), process 5100 ( FIG. 51 ), process 5200 ( FIG. 52 ), process 5300 ( FIG. 54 Figure 33 ) and process 3500( Figure 35), 3700 (Figure 37), 3900 (Figure 39), 4100 (Figure 41), 4300 (Figure 43). Computer-readable storage media can be any medium that can tangibly contain or store computer-executable instructions for use by or in conjunction with instruction execution systems, devices, and apparatuses. In some examples, the storage medium is a transient computer-readable storage medium. In some examples, the storage medium is a non-transitory computer-readable storage medium. Non-transitory computer-readable storage media may include, but are not limited to, magnetic storage devices, optical storage devices, and / or semiconductor storage devices. Examples of such storage devices include magnetic disks, optical disks based on CD, DVD, or Blu-ray technology, and persistent solid-state memory such as flash memory, solid-state drives, and the like. The personal electronic device 500 is not limited to Figure 5B components and configurations, but may include other components or additional components in a variety of configurations.

[0325] As used herein, the term "indicator" refers to an indication that is optionally provided on device 100, 300, and / or 500 ( Figure 1A 、 Figure 3 and Figures 5A to 5B ) on a display screen of a computer. For example, an image (e.g., an icon), a button, and text (e.g., a hyperlink) optionally each constitute an affordance.

[0326] As used herein, the term "focus selector" refers to an input element that indicates the current portion of a user interface with which a user is interacting. In some implementations that include a cursor or other position marker, the cursor acts as a "focus selector" such that when the cursor is over a particular user interface element (e.g., a button, window, slider, or other user interface element), a focus selector is displayed on a touch-sensitive surface (e.g., Figure 3 Touchpad 355 or Figure 4B In the event that an input (e.g., a press input) is detected on the touch-sensitive surface 451 in FIG, the particular user interface element is adjusted according to the detected input. In the case of a touch screen display (e.g., a touch screen display) that enables direct interaction with user interface elements on the touch screen display Figure 1A touch-sensitive display system 112 or Figure 4AIn some implementations of the touch screen 112 in FIG. 1 , a detected contact on the touch screen acts as a “focus selector” such that when input (e.g., a press input by the contact) is detected at the location of a particular user interface element (e.g., a button, window, slider, or other user interface element) on the touch screen display, the particular user interface element is adjusted according to the detected input. In some implementations, the focus moves from one area of ​​the user interface to another area of ​​the user interface without corresponding movement of a cursor or movement of a contact on the touch screen display (e.g., by using a tab key or arrow keys to move the focus from one button to another); in these implementations, the focus selector moves according to the movement of the focus between different areas of the user interface. Regardless of the specific form the focus selector takes, the focus selector is generally a user interface element (or contact on the touch screen display) that is controlled by the user to deliver the user's intended interaction with the user interface (e.g., by indicating to the device the element of the user interface with which the user desires to interact). For example, when a press input is detected on a touch-sensitive surface (e.g., a touchpad or touch screen), the position of a focus selector (e.g., a cursor, contact, or selection box) over a corresponding button will indicate that the user intends to activate the corresponding button (rather than other user interface elements shown on the device display).

[0327] As used in the specification and claims, the term "characteristic intensity" of a contact refers to a characteristic of the contact based on one or more intensities of the contact. In some embodiments, the characteristic intensity is based on multiple intensity samples. The characteristic intensity is optionally based on a predefined number of intensity samples or a set of intensity samples collected during a predetermined time period (e.g., 0.05 seconds, 0.1 seconds, 0.2 seconds, 0.5 seconds, 1 second, 2 seconds, 5 seconds, 10 seconds) relative to a predefined event (e.g., after contact is detected, before contact is detected to be lifted off, before or after contact begins to move, before contact ends, before or after contact is detected to increase in intensity, and / or before or after contact is detected to decrease in intensity). The characteristic intensity of a contact is optionally based on one or more of the following: the maximum value of the intensity of the contact, the mean value of the intensity of the contact, the average value of the intensity of the contact, the value at the top 10% of the intensity of the contact, the half-maximum value of the intensity of the contact, the 90% maximum value of the intensity of the contact, etc. In some embodiments, the duration of the contact is used in determining the characteristic intensity (e.g., when the characteristic intensity is the average value of the intensity of the contact over time). In some embodiments, the feature strength is compared to a set of one or more strength thresholds to determine whether the user has performed an operation. For example, the set of one or more strength thresholds optionally includes a first strength threshold and a second strength threshold. In this example, a contact whose feature strength does not exceed the first threshold results in a first operation, a contact whose feature strength exceeds the first strength threshold but does not exceed the second strength threshold results in a second operation, and a contact whose feature strength exceeds the second threshold results in a third operation. In some embodiments, a comparison between the feature strength and one or more thresholds is used to determine whether to perform one or more operations (e.g., whether to perform the corresponding operation or to abandon the corresponding operation) rather than to determine whether to perform the first operation or the second operation.

[0328] Figure 5C Detecting multiple contacts 552A-552E on touch-sensitive display 504 using multiple intensity sensors 524A-524D is shown. Figure 5C Also included is an intensity graph that shows the current intensity measurements of intensity sensors 524A-524D relative to intensity units. In this example, the intensity measurements of intensity sensors 524A and 524D are both 9 intensity units, and the intensity measurements of intensity sensors 524B and 524C are both 7 intensity units. In some implementations, the cumulative intensity is the sum of the intensity measurements of multiple intensity sensors 524A-524D, which in this example is 32 intensity units. In some embodiments, each contact is assigned a corresponding intensity, which is a portion of the cumulative intensity. Figure 5D554. The cumulative strength assigned to contacts 552A-552E based on their distance from the center of force 554 is shown. In this example, each of contacts 552A, 552B, and 552E is assigned a strength of the contact of 8 strength units of the cumulative strength, and each of contacts 552C and 552D is assigned a strength of the contact of 4 strength units of the cumulative strength. More generally, in some embodiments, each contact j is assigned a corresponding strength Ij that is a portion of the cumulative strength A according to a predefined mathematical function Ij=A·(Dj / ΣDi), where Dj is the distance of the corresponding contact j from the center of force, and ΣDi is the sum of the distances of all corresponding contacts (e.g., i=1 to the last) from the center of force. The reference may be performed using an electronic device similar to or identical to device 100, 300, or 500. Figures 5C to 5D In some embodiments, the characteristic intensity of the contact is based on one or more intensities of the contact. In some embodiments, the intensity sensor is used to determine a single characteristic intensity (e.g., a single characteristic intensity of a single contact). It should be noted that the intensity map is not part of the displayed user interface, but is included in the Figure 5C-5D To help readers.

[0329] In some embodiments, a portion of a gesture is identified for determining the characteristic strength. For example, the touch-sensitive surface optionally receives a continuous swipe contact that transitions from a starting position and reaches an end position where the contact strength increases. In this example, the characteristic strength of the contact at the end position is optionally based only on a portion of the continuous swipe contact, rather than the entire swipe contact (e.g., only the portion of the swipe contact at the end position). In some embodiments, a smoothing algorithm is optionally applied to the intensity of the swipe contact before determining the characteristic strength of the contact. For example, the smoothing algorithm optionally includes one or more of the following: an unweighted sliding average smoothing algorithm, a triangular smoothing algorithm, a median filter smoothing algorithm, and / or an exponential smoothing algorithm. In some cases, these smoothing algorithms eliminate narrow peaks or dips in the intensity of the swipe contact to achieve the purpose of determining the characteristic strength.

[0330] The intensity of the contact on the touch-sensitive surface is optionally characterized relative to one or more intensity thresholds, such as a contact detection intensity threshold, a light press intensity threshold, a deep press intensity threshold, and / or one or more other intensity thresholds. In some embodiments, the light press intensity threshold corresponds to an intensity at which the device will perform an operation typically associated with clicking a button of a physical mouse or touchpad. In some embodiments, the deep press intensity threshold corresponds to an intensity at which the device will perform an operation different from the operation typically associated with clicking a button of a physical mouse or touchpad. In some embodiments, when a contact is detected with a characteristic intensity below the light press intensity threshold (e.g., and above a nominal contact detection intensity threshold, contacts below the nominal contact detection intensity threshold are no longer detected), the device will move the focus selector in accordance with the movement of the contact on the touch-sensitive surface, without performing an operation associated with the light press intensity threshold or the deep press intensity threshold. Generally speaking, unless otherwise stated, these intensity thresholds are consistent between different groups of user interface illustrations.

[0331] An increase in contact feature intensity from an intensity below a light press intensity threshold to an intensity between the light press intensity threshold and the deep press intensity threshold is sometimes referred to as a "light press" input. An increase in contact feature intensity from an intensity below a deep press intensity threshold to an intensity above the deep press intensity threshold is sometimes referred to as a "deep press" input. An increase in contact feature intensity from an intensity below a contact detection intensity threshold to an intensity between the contact detection intensity threshold and the light press intensity threshold is sometimes referred to as detecting a contact on the touch surface. A decrease in contact feature intensity from an intensity above the contact detection intensity threshold to an intensity below the contact detection intensity threshold is sometimes referred to as detecting a contact lifted from the touch surface. In some embodiments, the contact detection intensity threshold is zero. In some embodiments, the contact detection intensity threshold is greater than zero.

[0332] In some embodiments described herein, one or more operations are performed in response to detecting a gesture that includes a corresponding press input or in response to detecting a corresponding press input performed using a corresponding contact (or multiple contacts), wherein the corresponding press input is detected at least in part based on detecting an increase in the intensity of the contact (or multiple contacts) to above a press input intensity threshold. In some embodiments, the corresponding operation is performed in response to detecting an increase in the intensity of the corresponding contact to above the press input intensity threshold (e.g., a "down stroke" of the corresponding press input). In some embodiments, the press input includes an increase in the intensity of the corresponding contact to above the press input intensity threshold and a subsequent decrease in the intensity of the contact to below the press input intensity threshold, and the corresponding operation is performed in response to detecting a subsequent decrease in the intensity of the corresponding contact to below the press input threshold (e.g., an "up stroke" of the corresponding press input).

[0333] Figure 5E-5HDetection of a gesture is shown, the gesture comprising contact 562 with an intensity from below Figure 5E Light press intensity threshold in L ”) increases to a value higher than Figure 5H The deep press intensity threshold in D ”). On the displayed user interface 570 including application icons 572A-572D displayed in the predefined area 574, a cursor 576 is displayed over the application icon 572B corresponding to application 2, and a gesture performed using contact 562 is detected on the touch-sensitive surface 560. In some embodiments, the gesture is detected on the touch-sensitive display 504. The intensity sensor detects the intensity of the contact on the touch-sensitive surface 560. The device determines that the intensity of the contact 562 is above the deep press intensity threshold (for example, “IT D ”) reaches a peak above. Contact 562 is maintained on touch-sensitive surface 560. In response to detecting the gesture, and according to the intensity rising to the deep press intensity threshold (e.g., “IT D ”) above contact 562, displays reduced-scale representations 578A-578C (e.g., thumbnails) of documents recently opened for Application 2, as shown in FIG. Figure 5F-5H In some embodiments, the intensity is a characteristic intensity of the contact compared to one or more intensity thresholds. It should be noted that the intensity map for contact 562 is not part of the displayed user interface, but is included in the Figure 5E-5H To help readers.

[0334] In some embodiments, the display of representations 578A-578C includes animation. For example, representation 578A is initially displayed near application icon 572B, as shown in FIG. Figure 5F As the animation progresses, representation 578A moves upward and representation 578B is displayed near application icon 572B, as shown. Figure 5G Then, representation 578A moves upward, 578B moves upward toward representation 578A, and representation 578C is displayed near application icon 572B, as shown in FIG. Figure 5H In some embodiments, the animation progresses according to the intensity of contact 562, as shown in FIG. Figure 5F-5G , where representations 578A-578C appear and decrease as the intensity of contact 562 moves toward a deep press intensity threshold (e.g., “IT D In some embodiments, the intensity according to which the animation progresses is the characteristic intensity of the contact. The reference may be performed using an electronic device similar to or identical to device 100, 300, or 500. Figure 5E-5H The operation described.

[0335] In some embodiments, the device employs intensity hysteresis to avoid unexpected inputs, sometimes referred to as "jitter," where the device defines or selects a hysteresis intensity threshold that has a predefined relationship to a press input intensity threshold (e.g., the hysteresis intensity threshold is X intensity units lower than the press input intensity threshold, or the hysteresis intensity threshold is 75%, 90%, or some reasonable proportion of the press input intensity threshold). Thus, in some embodiments, a press input includes an increase in the intensity of the corresponding contact to above the press input intensity threshold and a subsequent decrease in the intensity of the contact to below a hysteresis intensity threshold corresponding to the press input intensity threshold, and a corresponding operation is performed in response to detecting that the intensity of the corresponding contact subsequently decreases to below the hysteresis intensity threshold (e.g., an "upstroke" of the corresponding press input). Similarly, in some embodiments, a press input is detected only when the device detects that the contact intensity increases from an intensity equal to or below the hysteresis intensity threshold to an intensity equal to or above the press input intensity threshold and, optionally, that the contact intensity subsequently decreases to an intensity equal to or below the hysteresis intensity, and a corresponding operation is performed in response to detecting the press input (e.g., an increase in contact intensity or a decrease in contact intensity, depending on the circumstances).

[0336] For ease of explanation, a description of an operation performed in response to a press input associated with a press input intensity threshold or in response to a gesture including a press input is optionally triggered in response to detecting any of the following: contact intensity increasing above the press input intensity threshold, contact intensity increasing from an intensity below a hysteresis intensity threshold to an intensity above the press input intensity threshold, contact intensity decreasing below the press input intensity threshold, and / or contact intensity decreasing below a hysteresis intensity threshold corresponding to the press input intensity threshold. Additionally, in examples where an operation is described as being performed in response to detecting that the intensity of the contact decreases below the press input intensity threshold, the operation is optionally performed in response to detecting that the intensity of the contact decreases below a hysteresis intensity threshold that corresponds to and is less than the press input intensity threshold.

[0337] As used herein, an "installed application" refers to a software application that has been downloaded to an electronic device (e.g., device 100, 300, and / or 500) and is ready to be launched (e.g., become open) on the device. In some embodiments, a downloaded application becomes an installed application using an installer program that extracts program portions from the downloaded software package and integrates the extracted portions with the computer system's operating system.

[0338] As used herein, the term "open application" or "executing application" refers to a software application that has persisted state information (e.g., as part of device / global internal state 157 and / or application internal state 192). An open or executing application is optionally any of the following types of applications:

[0339] The active application, which is currently displayed on the display of the device on which the application is being used;

[0340] Background applications (or background processes) that are not currently displayed but whose processes are being processed by one or more processors; and

[0341] • A suspended or dormant application that is not running but has state information stored in memory (volatile and non-volatile, respectively) that can be used to resume execution of the application.

[0342] As used herein, the term "closed application" refers to a software application that does not retain state information (e.g., the state information of a closed application is not stored in the device's memory). Thus, closing an application includes stopping and / or removing the application's application process and removing the application's state information from the device's memory. Generally speaking, while in a first application, opening a second application does not close the first application. When the second application is displayed and the first application ceases to be displayed, the first application becomes a background application.

[0343] Attention is now turned to an embodiment of a user interface ("UI") and associated processes implemented on an electronic device, such as portable multifunction device 100, device 300, or device 500.

[0344] Figure 6 Example devices connected via one or more communication channels to participate in a transaction according to some embodiments are shown. One or more example electronic devices (e.g., devices 100, 300, and 500) are configured to optionally detect input (e.g., specific user input, NFC field) and optionally transmit payment information (e.g., using NFC). The one or more electronic devices optionally include NFC hardware and are configured to support NFC.

[0345] The electronic device (e.g., devices 100, 300, and 500) is optionally configured to store payment account information associated with each of one or more payment accounts. The payment account information includes, for example, one or more of the following: a person's name or company name, a billing address, a login name, a password, an account number, an expiration date, a security code, a phone number, a bank associated with the payment account (e.g., an issuing bank), and a card network identifier. In some examples, the payment account information includes an image, such as a photo of a payment card (e.g., a photo taken by the device and / or received by the device). In some examples, the electronic device receives user input including at least some payment account information (e.g., receiving a user-entered credit card number, debit card number, account number, or shopping card number and expiration date). In some examples, the electronic device detects at least some payment account information from an image (e.g., of a payment card captured by a camera sensor of the device). In some examples, the electronic device receives at least some payment account information from another device (e.g., another user device or a server). In some examples, the electronic device receives payment account information from a server associated with another service (e.g., an application for renting or selling audio files and / or video files) for which the user or user device's account has previously made purchases or for which payment account data is identified.

[0346] In some embodiments, a payment account is added to an electronic device (e.g., devices 100, 300, and 500) so that the payment account information is securely stored on the electronic device. In some examples, after a user initiates such a process, the electronic device transmits the payment account information to a transaction coordination server, which then communicates with a server operated by the account's payment network (e.g., a payment server) to ensure the validity of the information. The electronic device is optionally configured to receive a script from the server that allows the electronic device to program the account's payment information onto a secure element.

[0347] In some embodiments, communication between devices 100, 300, and 500 facilitates transactions (e.g., general transactions or specific transactions). For example, a first electronic device (e.g., 100) may be used as a configuration device or a management device and may send new or updated payment account data (e.g., information about a new account, updated information about an existing account, and / or warnings about an existing account) to a second electronic device (e.g., 500). As another example, a first electronic device (e.g., 100) may send data to a second electronic device, wherein the data reflects information about a payment transaction facilitated at the first electronic device. The information optionally includes one or more of the following: the payment amount, the account used, the time of purchase, and whether to change the default account. The second device (e.g., 500) optionally uses such information to update the default payment account (e.g., based on a learning algorithm or explicit user input).

[0348] Electronic devices (e.g., 100, 300, 500) are configured to communicate with each other via any of a variety of networks. For example, the devices communicate using a Bluetooth connection 608 (e.g., including a traditional Bluetooth connection or a Bluetooth low energy connection) or using a WiFi network 606. Communications between user devices are optionally regulated to reduce the likelihood of inappropriate sharing of information between devices. For example, communication regarding payment information requires that the communicating devices be paired (e.g., associated with each other via explicit user interaction) or associated with the same user account.

[0349] In some embodiments, an electronic device (e.g., 100, 300, 500) is used to communicate with a point-of-sale (POS) payment terminal 600, which optionally supports NFC. The communication is optionally carried out using various communication channels and / or technologies. In some examples, the electronic device (e.g., 100, 300, 500) uses an NFC channel 610 to communicate with the payment terminal 600. In some embodiments, the payment terminal 600 uses a peer-to-peer NFC mode to communicate with the electronic device (e.g., 100, 300, 500). The electronic device (e.g., 100, 300, 500) is optionally configured to transmit a signal to the payment terminal 600 that includes payment information of a payment account (e.g., a default account or an account selected for a particular transaction).

[0350] In some embodiments, continuing with the transaction includes transmitting a signal including payment information of an account (such as a payment account). In some embodiments, continuing with the transaction includes reconfiguring the electronic device (e.g., 100, 300, 500) to respond as a contactless payment card (such as an NFC-enabled contactless payment card) and then transmitting the account credentials via NFC to, for example, a payment terminal 600. In some embodiments, after transmitting the account credentials via NFC, the electronic device is reconfigured not to respond as a contactless payment card (e.g., requiring authorization before being reconfigured to respond as a contactless payment card via NFC again).

[0351] In some embodiments, the generation and / or transmission of the signal is controlled by a security element in an electronic device (e.g., 100, 300, 500). Before releasing the payment information, the security element optionally requires specific user input. For example, the security element optionally requires: detecting the electronic device being worn, detecting button presses, detecting password input, detecting touch, detecting one or more option selections (e.g., option selections received when interacting with an application), detecting fingerprint signatures, detecting voice or voice commands, and / or detecting gestures or movements (e.g., rotation or acceleration). In some examples, if a communication channel (e.g., NFC communication channel) with another device (e.g., payment terminal 600) is established within a limited time period from detecting the input, the security element releases the payment information so that it is transmitted to another device (e.g., payment terminal 600). In some examples, the security element is a hardware component that controls the release of security information. In some examples, the security element is a software component that controls the release of security information.

[0352] In some embodiments, the protocols associated with transaction participation depend on, for example, the device type. For example, the conditions for generating and / or transmitting payment information may be different for a wearable device (e.g., device 500) and a phone (e.g., device 100). For example, the generation conditions and / or transmission conditions for a wearable device include detecting that a button has been pressed (e.g., after security verification), while the corresponding conditions for a phone do not require a button press, but rather require detection of a specific interaction with an application. In some embodiments, the conditions for transmitting and / or releasing payment information include receiving specific input on each of a plurality of devices. For example, the release of payment information optionally requires detection of a fingerprint and / or passcode at a device (e.g., device 100), and detection of a mechanical input (e.g., a button press) on another device (e.g., device 500).

[0353] Payment terminal 600 optionally uses the payment information to generate a signal for transmission to payment server 604 to determine whether the payment is authorized. Payment server 604 optionally includes any device or system configured to receive payment information associated with a payment account and determine whether the proposed purchase is authorized. In some examples, payment server 604 includes a server of an issuing bank. Payment terminal 600 communicates with payment server 604 directly or indirectly via one or more devices or systems (e.g., a server of an acquiring bank and / or a server of a card network).

[0354] Payment server 604 optionally uses at least some of the payment information to identify a user account from a database of user accounts (e.g., 602). For example, each user account includes payment information. The account is optionally located by locating an account with specific payment information that matches the information from the POS communication. In some examples, payment is denied when the provided payment information is inconsistent (e.g., the expiration date does not correspond to the credit card number, debit card number, or shopping card number) or when no account includes payment information that matches the information from the POS communication.

[0355] In some embodiments, the user account data also identifies one or more limits (e.g., credit limit); current or previous balances; previous transaction dates, locations, and / or amounts; account status (e.g., active or frozen); and / or authorization instructions. In some examples, the payment server (e.g., 604) uses this data to determine whether to authorize a payment. For example, the payment server may deny payment when the purchase amount added to the current balance would cause the account limit to be exceeded, when the account is frozen, when the previous transaction amount exceeds a threshold, or when the number or frequency of previous transactions exceeds a threshold.

[0356] In some embodiments, the payment server 604 responds to the POS payment terminal 600 with an indication of whether the proposed purchase is authorized or denied. In some examples, the POS payment terminal 600 transmits a signal to the electronic device (e.g., 100, 300, 500) to identify the result. For example, when the purchase is authorized (e.g., via a transaction coordination server that manages a transaction application on the user device), the POS payment terminal 600 sends a receipt to the electronic device (e.g., 100, 300, 500). In some cases, the POS payment terminal 600 presents an output (e.g., a visual output or an audio output) indicating the result. The payment may be transmitted to the merchant as part of the authorization process, or may be transmitted later.

[0357] In some embodiments, the electronic device (e.g., 100, 300, 500) participates in a transaction that is completed without involving the POS payment terminal 600. For example, upon detecting that the mechanical input has been received, the secure element in the electronic device (e.g., 100, 300, 500) releases the payment information to allow an application on the electronic device to access the information (e.g., and transmit the information to a server associated with the application).

[0358] In some embodiments, the electronic device (e.g., 100, 300, 500) is in a locked state or an unlocked state. In the locked state, the electronic device is powered on and is operable, but it is prevented from performing a predefined set of operations in response to user input. The predefined set of operations optionally includes navigating between user interfaces, activating or deactivating a predefined set of functions, and activating or deactivating certain applications. The locked state can be used to prevent unconscious or unauthorized use of some functions of the electronic device, or to activate or deactivate some functions on the electronic device. In the unlocked state, the electronic device 100 is powered on and is operable, and is not prevented from performing at least a portion of a predefined set of operations that cannot be performed when in the locked state.

[0359] When the device is in the locked state, the device is said to be locked. In some embodiments, the device in the locked state is optionally responsive to a restricted set of user inputs, including input corresponding to an attempt to transition the device to the unlocked state or input corresponding to turning the device off.

[0360] In some examples, a security element (e.g., 115) is a hardware component (e.g., a secure microcontroller chip) configured to securely store data or algorithms so that the device cannot access the securely stored data without the correct authentication information from the user of the device. Keeping the securely stored data in a security element separate from other storage devices on the device prevents access to the securely stored data, even if other storage locations on the device are compromised (e.g., by malicious code or other attempts to compromise information stored on the device). In some examples, the security element provides (or releases) payment information (e.g., account number and / or transaction-specific dynamic security code). In some examples, the security element provides (or releases) payment information in response to the device receiving authorization, such as user authentication (e.g., fingerprint authentication; password authentication; detecting two presses of a hardware button when the device is in an unlocked state and, optionally, while the device has been continuously on the user's wrist since unlocking the device by providing authentication credentials to the device, wherein the continued presence of the device on the user's wrist is determined by periodically checking that the device is in contact with the user's skin). For example, the device detects a fingerprint at the device's fingerprint sensor (e.g., a fingerprint sensor integrated into a button). The device determines whether the fingerprint matches the registered fingerprint. Based on the determination that the fingerprint matches the registered fingerprint, the secure element provides (or releases) the payment information. Based on the determination that the fingerprint does not match the registered fingerprint, the secure element forgoes providing (or releasing) the payment information.

[0361] Attention is now turned to an embodiment of a user interface ("UI") and associated processes implemented on an electronic device, such as portable multifunction device 100, device 300, or device 500.

[0362] Figures 7A to 7S Exemplary user interfaces are shown for providing an instructional tutorial for enrolling a biometric feature on an electronic device (e.g., device 100, device 300, or device 500) according to some examples. The user interfaces in these figures are used to illustrate the processes described below, including the process in FIG. 8 .

Figures 7A to 7SIn the illustrative example shown in , electronic device 700 is a smartphone. In other examples, electronic device 1500 can be a different type of electronic device, such as a wearable device (e.g., a smartwatch). Electronic device 700 has a display 702, one or more input devices (e.g., a touch screen, buttons, a microphone for display 1502), and a wireless communication radio. In some examples, the electronic device includes multiple cameras. In some examples, the electronic device includes only one camera. In some examples, the electronic device includes one or more biometric sensors (e.g., biometric sensor 703), which optionally include a camera, such as an infrared camera, a thermal imaging camera, or a combination thereof. In some examples, one or more of the biometric sensors is a biometric sensor (e.g., a facial recognition sensor), such as those described in U.S. Serial No. 14 / 341,860, entitled “Overlapping Pattern Projector,” filed on July 14, 2014, U.S. Publication No. 2016 / 0025993, and U.S. Patent No. 9,098,931, entitled “Scanning Projects and Image Capture Modules For 3D Mapping,” each of which is hereby incorporated by reference in its entirety for any purpose. In some examples, the electronic device includes a depth camera, such as an infrared camera, a thermal imaging camera, or ...
