Description

Application Launch Methods and Devices

[0001] This application claims priority to Chinese Patent Application No. 202411215330.2, filed on August 30, 2024, entitled “Application Launching Method and Apparatus”, the entire contents of which are incorporated herein by reference. Technical Field

[0002] This application relates to the field of terminal technology, specifically to an application launch method and apparatus. Background Technology

[0003] When not in use for an extended period, the device's system will enter a low-power mode, and the display will turn off to conserve power. If the user has configured security authentication, the device will automatically enter a lock screen state when the screen is off. To use the device, a password verification or other steps will be required to access the system desktop.

[0004] To facilitate the quick activation of frequently used applications in screen-off scenarios, some manufacturers have introduced quick wake-up functions to launch specific applications rapidly, enabling more convenient human-computer interaction. However, because quick wake-up functions in screen-off mode cannot simultaneously recognize identity information, security authentication is required again when accessing applications involving personal privacy, such as contacts, chat software, and photo albums, resulting in an unsmooth user experience. Summary of the Invention

[0005] This application provides an application launch method and apparatus that allows users to quickly launch a specific application with just one operation when the terminal device is in a screen-off and locked state, balancing security and convenience and providing users with a smooth interactive experience.

[0006] In a first aspect, an application launch method is provided, the method comprising: on a first interface of a terminal device, acquiring a first movement trajectory of a user on the screen of the terminal device, the first movement trajectory passing through the fingerprint sensing area of ​​the terminal device, the first interface being the interface of the terminal device in a screen-off and locked state; and responding to the first movement trajectory, presenting a second interface, the second interface being the interface of the application corresponding to the first movement trajectory.

[0007] This application provides an application launch method in which the user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be acquired at the same time as the movement trajectory. The user only needs to operate once to quickly launch a specific application, which balances security and convenience and brings a smooth interactive experience to the user.

[0008] The first interface includes, but is not limited to, an interface where the terminal device is completely black, an interface where the terminal device displays only the time in a black screen state, an interface where the terminal device displays only the date in a black screen state, an interface where the terminal device displays only a specified image in a black screen state, an interface where the terminal device displays only a music progress bar in a black screen state, and an interface where the terminal device displays only volume control in a black screen state. Optionally, the time on the interface can be in numerical form or in graphic form, such as time displayed in the form of a clock. Optionally, the first interface can also be a combination of the above-mentioned display interfaces. For example, the first interface can be an interface where the terminal device displays only the time and date in a black screen state, or an interface where the terminal device displays only a music progress bar and volume control in a black screen state; this application does not limit this.

[0009] The fingerprint sensing area is the area on the screen of a terminal device used to sense the user's fingerprint. When the user's finger is located in the fingerprint sensing area and in contact with the screen, the terminal device can acquire the user's fingerprint, which can be used to unlock the terminal device's system.

[0010] The movement trajectories in this application embodiment include, but are not limited to, sliding along different directions, numbers, English characters, and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circles, triangles, hearts, etc. The first, second, third, fourth, and fifth movement trajectories in this application embodiment are all the above-mentioned movement trajectories.

[0011] This application allows for the pre-setting of the correspondence between movement tracks and applications. Optionally, one movement track can correspond to one application, or multiple movement tracks can correspond to one application; this application does not impose any limitations on this. For example, movement track "S" corresponds to launching the photo album application, movement tracks "W" and "L" correspond to quickly launching the contacts application, and movement track "M" corresponds to launching the music player application.

[0012] In one possible implementation scenario, the mapping between movement trajectory and application can be pre-configured before the terminal device leaves the factory. For example, this can be communicated to the user through the instruction manual, allowing the user to quickly launch a specific application based on the mapping between movement trajectory and application. For instance, movement trajectory "S" corresponds to launching the photo album application, movement trajectories "W" and "L" correspond to quickly launching the contacts application, and movement trajectory "M" corresponds to launching the music playback application.

[0013] The second interface is the user interface of the application, including but not limited to the main interface of the application and the sub-interfaces of the application that can be switched to by buttons on the main interface.

[0014] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: on the first interface, acquiring a second movement trajectory of the user on the screen, the second movement trajectory passing through the fingerprint sensing area; in response to the second movement trajectory, presenting a third interface, the third interface being a failure prompt interface.

[0015] Users can register at least one preset fingerprint and at least one preset movement trajectory while the terminal device is in use. Each preset movement trajectory corresponds to the quick launch of an application. If the similarity between the fingerprint acquired by the terminal device and the preset fingerprint is greater than a first preset matching threshold, the fingerprint match is successful; if the similarity is less than or equal to the first preset matching threshold, the fingerprint match fails. Similarly, if the similarity between the movement trajectory acquired by the terminal device and the preset movement trajectory is greater than a second preset matching threshold, the movement trajectory match is successful; if the similarity is less than or equal to the second preset matching threshold, the movement trajectory match fails.

[0016] If fingerprint matching fails, the terminal device can display a third interface. For example, if fingerprint matching fails and the second movement trajectory matching also fails, the terminal device displays a third interface. Alternatively, if fingerprint matching fails but the second movement trajectory matching succeeds, the terminal device displays a third interface.

[0017] In some possible implementations, the third interface may include failure message text or failure message icons. For example, failure message text may include, but is not limited to, "Unlock failed," "Operation failed," "Try again," and "Error." Failure message icons may include, but are not limited to, failure animations and "×" symbols.

[0018] This application provides an application launch method that can present a third interface when the user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0019] In conjunction with the first aspect, in some implementations of the first aspect, the third interface includes a fingerprint matching failure prompt interface, a movement trajectory matching failure prompt interface, or a prompt to re-enter the information interface.

[0020] The fingerprint matching failure prompt interface can include text prompts such as "Fingerprint matching failed", "Fingerprint matching error", "Input error", "Fingerprint recognition failed", "Recognition failed", etc., and may also include patterns such as "×".

[0021] The motion trajectory matching failure prompt interface can include text prompts such as "motion trajectory matching failure", "motion trajectory matching error", "input error", "motion trajectory recognition failure", "recognition failure", "gesture recognition failure", etc., and may also include patterns such as "×".

[0022] The prompt to re-enter the password can include prompts such as "Please re-enter", "Enter again", or "Try again", or it can directly display the password input button.

[0023] This application provides an application launch method that can present a third interface when the user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0024] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: on the first interface, acquiring a third movement trajectory of the user on the screen, the third movement trajectory passing through the fingerprint sensing area; in response to the third movement trajectory, presenting a fourth interface, the fourth interface being the desktop homepage of the terminal device.

[0025] The home screen of a terminal device is typically the interface a user sees on the screen when they first start the device. This home screen can include one or more of the following: application icons, application folders, application widgets, wallpaper, search bar, bottom navigation bar, and theme animations.

[0026] If fingerprint matching is successful but third movement trajectory matching fails, the terminal device can display a fourth interface.

[0027] This application provides an application launch method that can securely unlock the terminal device and display the terminal device's home screen when fingerprint matching is successful but movement trajectory matching fails. Compared to traditional swipe unlock without security protection, this method adds fingerprint verification, improves security, and protects user privacy. Furthermore, compared to the traditional fingerprint pressing unlock method, this unlocking method is more in line with users' mobile phone usage habits and can bring a better interactive and responsive experience.

[0028] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: on the first interface, acquiring a fourth movement trajectory of the user on the screen, the fourth movement trajectory passing through the fingerprint sensing area; in response to the fourth movement trajectory, presenting a fifth interface, the fifth interface being the application interface displayed by the terminal device before the screen is turned off.

[0029] If fingerprint matching is successful but movement trajectory matching fails, the terminal device can display a fifth interface. This fifth interface represents the application interface displayed on the screen before the screen turned off. For example, if the user was viewing the photo album before the screen turned off, the fifth interface would be the photo album application's interface. If the user was using a chat application before the screen turned off, the fifth interface would be the chat application's interface.

[0030] In one possible implementation scenario, if the time the terminal device is in a screen-off state is greater than a preset time threshold, then if fingerprint matching is successful but movement trajectory matching fails, the terminal device will display a fourth interface; if the time the terminal device is in a screen-off state is less than or equal to the preset time threshold, then if fingerprint matching is successful but movement trajectory matching fails, the terminal device will display a fifth interface.

[0031] This application provides an application launch method that, even when fingerprint matching is successful but movement trajectory matching fails, can securely unlock the terminal device and display the application interface used before the device screen was turned off. Compared to traditional swipe-to-unlock without security protection, this method adds fingerprint verification, improves security, and protects user privacy. Furthermore, compared to the traditional fingerprint-pressing unlock method, this unlocking method is more in line with users' mobile phone usage habits, providing a better interactive and responsive experience.

[0032] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: on the first interface, acquiring a fifth movement trajectory of the user on the screen, the fifth movement trajectory passing through the fingerprint sensing area; and in response to the fifth movement trajectory, presenting the first interface.

[0033] In the event of fingerprint matching failure, the terminal device can display the first interface. For example, if fingerprint matching fails and the second movement trajectory matching also fails, the terminal device displays the first interface. Alternatively, if fingerprint matching fails but the second movement trajectory matching succeeds, the terminal device displays the first interface. Even after obtaining the fifth movement trajectory within the first interface, the terminal device still displays the first interface. This can be understood as the terminal device's screen remaining unresponsive in the event of fingerprint matching failure.

[0034] This application provides an application launch method in which the terminal device does not react in the event that the user's fingerprint matching fails, thereby preventing unauthorized users from using the locked terminal device and ensuring the security and privacy of the terminal device.

[0035] In conjunction with the first aspect, in some implementations of the first aspect, obtaining the user's first movement trajectory on the screen of the terminal device includes: obtaining the first movement trajectory of the user on the screen of the terminal device through single-finger operation or multi-finger operation.

[0036] It should be understood that the movement trajectory obtained in the embodiments of this application is not limited to the movement trajectory obtained by a single finger, but can also be the movement trajectory obtained by multi-finger operation. The movement trajectory in the embodiments of this application includes, but is not limited to, sliding along different directions, numbers, English characters and special symbols, such as "W", "M", "S", "C", "V", "||", "|", "<", ">", "&", "8", circles, triangles, hearts, etc.

[0037] For example, users can obtain movement trajectories such as "W", "M", "S", "C", "V", "|", "<", ">", "&", "8", circle, triangle, and heart through single-finger operation. Users can obtain movement trajectories such as "||", "|||", "||||", "LL", "JJ", "ZZ", and heart through multi-finger operation.

[0038] This application provides an application launch method, which allows users to quickly launch a specific application by obtaining a first movement trajectory through single-finger or multi-finger operation. The launch gestures are highly selectable, enriching the types of applications that can be launched quickly.

[0039] In conjunction with the first aspect, in some implementations of the first aspect, the method further includes: obtaining the correspondence between the first movement trajectory input by the user and the application.

[0040] Users can pre-enter the mapping between movement tracks and applications on their terminal devices. Optionally, one movement track can correspond to one application, or multiple movement tracks can correspond to one application; this application does not impose any limitations on this. For example, movement track "S" corresponds to launching the photo album application, movement tracks "W" and "L" correspond to quickly launching the contacts application, and movement track "M" corresponds to launching the music player application.

[0041] This application provides an application launch method in which users can pre-record the correspondence between movement trajectory and application on the terminal device. Subsequently, when the terminal device is in a state of screen-off and lock, users can use a variety of different movement trajectories to open the corresponding application, thus enriching the types of applications that can be launched quickly.

[0042] In conjunction with the first aspect, in some implementations of the first aspect, the screen of the terminal device integrates a fingerprint sensor, which is used to acquire the user's fingerprint.

[0043] For example, the fingerprint sensor can be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc., and the fingerprint sensor can be located under the screen of the terminal device. When the user's finger swipes across the fingerprint sensing area, the terminal device can acquire the user's fingerprint through the fingerprint sensor.

[0044] This application provides an application launch method in which the user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be acquired at the same time as the movement trajectory. The user only needs to operate once to quickly launch a specific application, which balances security and convenience and brings a smooth interactive experience to the user.

[0045] In conjunction with the first aspect, in some implementations of the first aspect, the screen of the terminal device integrates a touch chip, which is used to acquire the first movement trajectory.

[0046] Optionally, a fingerprint sensor can also be used to acquire the user's movement trajectory on the screen. In one possible implementation scenario, the terminal device's screen integrates a large fingerprint sensor, which can simultaneously acquire the user's movement trajectory on the screen and their fingerprint.

[0047] This application provides an application launch method in which the user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be acquired at the same time as the movement trajectory. The user only needs to operate once to quickly launch a specific application, which balances security and convenience and brings a smooth interactive experience to the user.

[0048] In conjunction with the first aspect, in some implementations of the first aspect, the step of presenting the second interface in response to the first movement trajectory includes: acquiring the user's fingerprint when the first movement trajectory passes through the fingerprint sensing area; and presenting the second interface when the user's fingerprint successfully matches a preset fingerprint and the first movement trajectory successfully matches a preset movement trajectory.

[0049] A successful match between the user's fingerprint and a preset fingerprint indicates that the similarity between the user's fingerprint data acquired by the terminal device and the preset fingerprint is greater than a first preset matching threshold. A successful match between the first movement trajectory and a preset movement trajectory indicates that the similarity between the first movement trajectory acquired by the terminal device and the preset movement trajectory is greater than a second preset matching threshold. The preset fingerprint can be pre-registered by the user on the terminal device. The preset movement trajectory can be pre-registered by the user on the terminal device or be a factory-configured feature.

[0050] This application provides an application launch method in which the user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, and the user's fingerprint can be acquired at the same time as the movement trajectory. The user only needs to operate once to quickly launch a specific application, which balances security and convenience and brings a smooth interactive experience to the user.

[0051] In a second aspect, a computer device is provided, comprising a data acquisition module for acquiring a first movement trajectory of a user on the screen of a terminal device, wherein the first movement trajectory passes through a fingerprint sensing area of ​​the terminal device, and the first interface is the interface of the terminal device in a screen-off and locked state; and a decision module for responding to the first movement trajectory to present a second interface, wherein the second interface is the interface of an application corresponding to the first movement trajectory.

[0052] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is further configured to acquire, on the first interface, the second movement trajectory of the user on the screen, the second movement trajectory passing through the fingerprint sensing area; the decision module is further configured to respond to the second movement trajectory and present a third interface, the third interface being a failure prompt interface.

[0053] In conjunction with the second aspect, in some implementations of the second aspect, the third interface includes a fingerprint matching failure prompt interface, a movement trajectory matching failure prompt interface, or a prompt to re-enter the information interface.

[0054] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is further configured to acquire, on the first interface, a third movement trajectory of the user on the screen, the third movement trajectory passing through the fingerprint sensing area; the decision module is further configured to respond to the third movement trajectory and present a fourth interface, the fourth interface being the desktop homepage of the terminal device.

[0055] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is further configured to acquire, on the first interface, a fourth movement trajectory of the user on the screen, the fourth movement trajectory passing through the fingerprint sensing area; the decision module is further configured to respond to the fourth movement trajectory and present a fifth interface, the fifth interface being the application interface displayed by the terminal device before the screen is turned off.

[0056] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is further configured to acquire, on the first interface, the fifth movement trajectory of the user on the screen, the fifth movement trajectory passing through the fingerprint sensing area; the decision module is further configured to present the first interface in response to the fifth movement trajectory.

[0057] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is specifically used to: acquire the first movement trajectory of the user on the screen of the terminal device through single-finger operation or multi-finger operation.

[0058] In conjunction with the second aspect, in some implementations of the second aspect, the acquisition module is further configured to obtain the correspondence between the first movement trajectory input by the user and the application.

[0059] In conjunction with the second aspect, in some implementations of the second aspect, the screen of the terminal device integrates a fingerprint sensor for acquiring the user's fingerprint.

[0060] In conjunction with the second aspect, in some implementations of the second aspect, the screen of the terminal device integrates a touch chip, which is used to acquire the first movement trajectory.

[0061] In conjunction with the second aspect, in some implementations of the second aspect, the decision module is specifically used to: acquire the user's fingerprint when the first movement trajectory passes through the fingerprint sensing area; and present the second interface when the user's fingerprint successfully matches a preset fingerprint and the first movement trajectory successfully matches a preset movement trajectory.

[0062] The beneficial effects of the second aspect and any possible implementation of the second aspect correspond to the beneficial effects of the first aspect and any possible implementation of the first aspect, which will not be elaborated further.

[0093] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort should fall within the scope of protection of this application.

[0094] In the embodiments of this application, the words "exemplary," "for example," etc., are used to indicate that they are examples, illustrations, or descriptions. Any embodiment or design that is described as "exemplary" in this application should not be construed as being more preferred or advantageous than other embodiments or design options. Specifically, the use of the term "exemplary" is intended to present the concept in a concrete manner.

[0095] The business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. As those skilled in the art will know, with the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0096] References to "one embodiment" or "some embodiments" as described in this specification mean that one or more embodiments of this application include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0097] Hereinafter, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.

[0098] In this application, "at least one" means one or more, and "more than one" means two or more. "And / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can mean: A alone, A and B simultaneously, and B alone, where A and B can be singular or plural. The character " / " generally indicates that the preceding and following related objects are in an "or" relationship. "At least one of the following" or similar expressions refer to any combination of these items, including any combination of single or plural items. For example, at least one of a, b, or c can mean: a, b, c, ab, ac, bc, or abc, where a, b, and c can be single or multiple.

[0099] When not in use for an extended period, the device's system will enter a low-power mode, and the display will turn off to conserve power. If the user has set up security authentication methods such as password, fingerprint, face, or pattern recognition, the device will automatically enter a lock screen state when the screen is off. To use the device, a password verification or other steps are required to access the system desktop.

[0100] To facilitate the quick wake-up of frequently used applications in screen-off scenarios, some manufacturers have introduced a quick wake-up function to enable more convenient human-computer interaction. However, because the quick wake-up function in screen-off mode cannot simultaneously recognize identity information, security authentication is required again when accessing applications involving personal privacy, such as contacts, chat software, and photo albums, resulting in an unsmooth experience.

[0101] With the widespread adoption of fingerprint recognition technology in mobile devices, people are gradually getting used to using their fingerprints to unlock their systems and access their desktops. However, currently, fingerprint recognition devices are generally separate from the screen and are only used for system unlocking and secure payments.

[0102] Achieving both efficient and secure unlocking and quick application launch simultaneously has become a pressing need. In this embodiment, the user's movement trajectory on the screen passes through the fingerprint sensing area of ​​the terminal device, allowing the acquisition of the user's fingerprint while simultaneously acquiring the movement trajectory. The user only needs one operation to quickly launch a specific application, balancing security and convenience and providing a smooth interactive experience.

[0103] The methods provided in this application can be applied to terminal devices such as mobile phones, tablets, wearable devices, in-vehicle devices, augmented reality (AR) / virtual reality (VR) devices, laptops, ultra-mobile personal computers (UMPCs), netbooks, and personal digital assistants (PDAs). This application does not impose any restrictions on the specific type of terminal device.

[0104] For example, Figure 1 shows a schematic diagram of the structure of terminal device 100. Terminal device 100 may include a processor 110, an external memory interface 120, an internal memory 121, a universal serial bus (USB) interface 130, a charging management module 140, a power management module 141, a battery 142, an antenna 1, an antenna 2, a mobile communication module 150, a wireless communication module 160, an audio module 170, a speaker 170A, a receiver 170B, a microphone 170C, a headphone jack 170D, a sensor module 180, buttons 190, a motor 191, an indicator 192, a camera 193, a display screen 194, and a subscriber identification module (SIM) card interface 195, etc. The sensor module 180 may include a pressure sensor 180A, a gyroscope sensor 180B, a barometric pressure sensor 180C, a magnetic sensor 180D, an accelerometer sensor 180E, a distance sensor 180F, a proximity sensor 180G, an ultrasonic sensor 180H, a temperature sensor 180J, a touch sensor 180K, an ambient light sensor 180L, a bone conduction sensor 180M, etc.

[0105] It is understood that the structures illustrated in the embodiments of this application do not constitute a specific limitation on the terminal device 100. In other embodiments of this application, the terminal device 100 may include more or fewer components than illustrated, or combine some components, or split some components, or have different component arrangements. The illustrated components may be implemented in hardware, software, or a combination of software and hardware.

[0106] Processor 110 may include one or more processing units, such as: application processor (AP), modem processor, graphics processing unit (GPU), image signal processor (ISP), controller, memory, video codec, digital signal processor (DSP), baseband processor, and / or neural network processing unit (NPU), etc. Different processing units may be independent devices or integrated into one or more processors.

[0107] The controller can serve as the central nervous system and command center of the terminal device 100. The controller can generate operation control signals based on the instruction opcode and timing signals to control the fetching and execution of instructions.

[0108] The processor 110 may also include a memory for storing instructions and data. In some embodiments, the memory in the processor 110 is a cache memory. This memory can store instructions or data that the processor 110 has just used or that are used repeatedly. If the processor 110 needs to use the instruction or data again, it can retrieve it directly from the memory. This avoids repeated accesses, reduces the waiting time of the processor 110, and thus improves the efficiency of the system.

The first interface may also be an interface in which the terminal device displays only the help button when the screen is black. The above examples should not be construed as limiting this application.

[0184] The fingerprint sensing area is the area on the screen of a terminal device used to sense the user's fingerprint. When the user's finger is located in the fingerprint sensing area and in contact with the screen, the terminal device can acquire the user's fingerprint, which can be used to unlock the terminal device's system.

[0185] 320, responding to the first movement trajectory, presents the second interface.

[0186] In response to the first movement trajectory, a second interface is displayed on the screen of the terminal device. The second interface is the interface of the application corresponding to the first movement trajectory.

[0187] In one possible implementation, the second interface is presented when the user's fingerprint obtained by the terminal device is successfully matched with a preset fingerprint and the first movement trajectory is successfully matched with a preset movement trajectory.

[0188] The first movement trajectory includes, but is not limited to, swiping in different directions, numbers, English characters, and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circles, triangles, hearts, etc. This application can pre-set the correspondence between movement trajectories and applications. Optionally, one movement trajectory can correspond to one application, or multiple movement trajectories can correspond to one application; this application does not limit this. In one possible implementation scenario, the correspondence between movement trajectories and applications can also be pre-configured before the terminal device leaves the factory. For example, the user can be informed through the instruction manual, and the user can quickly launch a specific application based on the correspondence between the movement trajectory and the application. For example, movement trajectory "S" corresponds to launching a photo album application, movement trajectories "W" and "L" correspond to quickly launching a calculator application, movement trajectory "6" corresponds to launching a text messaging application, and movement trajectory "V" corresponds to launching a chat application.

[0189] The second interface is the user interface of the application, including but not limited to the main interface of the application and the sub-interfaces of the application that can be switched to by buttons on the main interface.

[0190] Figure 5 is a schematic diagram of a second interface presented in response to a first movement trajectory according to an embodiment of this application. The terminal device obtains the user's first movement trajectory "S" under the first interface. The fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the photo album application.

[0191] Figure 6 is a schematic diagram of another response to the first movement trajectory and the presentation of the second interface provided in the embodiment of this application. The terminal device obtains the user's first movement trajectory "W" under the first interface. The fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the counter application.

[0192] Figure 7 is a schematic diagram of another response to the first movement trajectory and the presentation of the second interface provided in the embodiment of this application. The terminal device obtains the user's first movement trajectory "6" under the first interface. The fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the SMS application.

[0193] Figure 8 is a schematic diagram of another response to the first movement trajectory and the presentation of the second interface provided by the embodiment of this application. The terminal device obtains the user's first movement trajectory "V" under the first interface. The fingerprint and the first movement trajectory are successfully matched, and the second interface is presented. The second interface is the user interface of the chat application.

[0194] Figure 9 is a schematic diagram of the movement trajectory provided in an embodiment of this application.

[0195] The first movement trajectory, second movement trajectory, third movement trajectory, fourth movement trajectory, and fifth movement trajectory in the embodiments of this application can be collectively referred to as movement trajectories.

[0196] The movement trajectories in this application include, but are not limited to, swiping in different directions, numbers, English characters, and special symbols, such as "W", "M", "S", "C", "||", "|", "V", "<", ">", "&", "8", circles, triangles, hearts, etc. Each pattern in Figure 9 can be a movement trajectory, meaning that users can quickly launch the corresponding application by drawing patterns in the grids on the screen when the terminal device is off and locked. It should be understood that the movement trajectory patterns in Figure 9 are merely examples and should not be construed as limiting this application.

[0197] Figure 10 is a schematic diagram of the movement trajectory obtained by the user through single-finger operation or multi-finger operation according to an embodiment of this application.

[0198] When the terminal device is off and locked, the user can slide on the screen using a single finger or multiple fingers. The terminal device will collect the user's movement trajectory and fingerprint. In Figure 10(a), the user obtains a triangular movement trajectory using a single finger; in Figure 10(b), the user obtains a "W" shaped movement trajectory using a single finger; in Figure 10(c), the user obtains a "|||" shaped movement trajectory using three fingers; and in Figure 10(d), the user obtains a heart-shaped movement trajectory using two fingers.

[0199] Figure 11 is a schematic diagram of the movement trajectory and identification area provided in the embodiments of this application.

[0200] The terminal device acquires the user's fingerprint through the fingerprint sensing area and the user's movement trajectory through the movement trajectory recognition area. The fingerprint sensing area and the movement trajectory recognition area can be the same area or different areas.

[0201] For example, a fingerprint sensor can simultaneously recognize fingerprints and movement trajectories. The screen of the terminal device can integrate a fingerprint sensor to simultaneously acquire the user's fingerprint and movement trajectories in the area of ​​the screen where the fingerprint sensor operates. In this case, the area of ​​the screen where the fingerprint sensor operates serves as both the fingerprint sensing area and the movement trajectory recognition area.

[0202] For example, fingerprint recognition can be achieved by a fingerprint sensor, and movement trajectory recognition can be achieved by a touch chip. The screen of the terminal device can integrate both a fingerprint sensor and a touch chip simultaneously, so that the user's fingerprint can be acquired in the area of ​​the screen where the fingerprint sensor operates, and the user's movement trajectory can be acquired in the area of ​​the screen where the touch chip operates. In this case, the area of ​​the screen where the fingerprint sensor operates is the fingerprint sensing area, and the area where the touch chip operates is the movement trajectory recognition area. It should be understood that when the fingerprint sensing area and the movement trajectory recognition area are different areas, the two areas can be in an inclusive relationship, a partially overlapping relationship, or a separate relationship.

[0203] The starting position of the movement trajectory can be within the fingerprint sensing area, the movement trajectory recognition area, or a non-recognition area. The ending position of the movement trajectory can also be within the fingerprint sensing area, the movement trajectory recognition area, or a non-recognition area. This application does not restrict the specific starting and ending positions of the movement trajectory, as long as at least part of the movement trajectory falls within the movement trajectory recognition area and the movement trajectory passes through the fingerprint sensing area. The non-recognition area includes all areas on the terminal device's screen other than the movement trajectory recognition area and the fingerprint sensing area.

[0204] In Figure 11(a), the fingerprint sensing area and the motion trajectory recognition area belong to the same area, and the area of ​​this area is smaller than the screen area of ​​the terminal device. The motion trajectory "W" falls entirely within this area. In Figure 11(b), the fingerprint sensing area and the motion trajectory recognition area belong to the same area, and the area of ​​this area is equal to the screen area of ​​the terminal device. The motion trajectory "○" falls entirely within this area. In Figure 11(c), the fingerprint sensing area and the motion trajectory recognition area belong to different areas. The areas of both the fingerprint sensing area and the motion trajectory recognition area are smaller than the screen area. The fingerprint sensing area is contained within the motion trajectory recognition area. The starting position of the motion trajectory "|" is within the motion trajectory recognition area, and the ending position of the motion trajectory "|" is within the non-recognition area. In Figure 11(d), the fingerprint sensing area and the motion trajectory recognition area belong to different areas. The area of ​​the motion trajectory recognition area is equal to the screen area. In Figure 11(e), the fingerprint sensing area and the motion trajectory recognition area are different areas. The areas of both the fingerprint sensing area and the motion trajectory recognition area are smaller than the screen area. They are two separate areas. The starting position of the motion trajectory "|" is within the motion trajectory recognition area, and the ending position of the motion trajectory "|" is within the fingerprint sensing area. In Figure 11(f), the fingerprint sensing area and the motion trajectory recognition area are different areas. The areas of both the fingerprint sensing area and the motion trajectory recognition area are smaller than the screen area. They partially overlap. The starting and ending positions of the motion trajectory "V" are both within the non-recognition area.

[0205] Figure 12 is an exemplary flowchart of another application launch method provided in an embodiment of this application.

[0206] 1210, on the first interface, obtain the second movement trajectory.

[0207] On the first interface of the terminal device, the user's second movement trajectory on the terminal device screen is acquired. The second movement trajectory passes through the fingerprint sensing area of ​​the terminal device.

[0208] For a description of the first interface, please refer to Figure 4. For a description of the second movement trajectory, please refer to Figure 9. This application will not repeat the description.

[0209] 1220, responding to the second movement trajectory, presents the third interface.

[0210] In response to the second movement trajectory, a third interface is displayed on the terminal device's screen; the third interface is a failure prompt interface.

[0211] If fingerprint matching fails, the terminal device can display a third interface. For example, if fingerprint matching fails and the second movement trajectory matching also fails, the terminal device displays a third interface. Alternatively, if fingerprint matching fails but the second movement trajectory matching succeeds, the terminal device displays a third interface.

[0212] The third interface may include failure message text or failure message images. For example, failure message text includes, but is not limited to, "Unlock failed," "Operation failed," "Try again," and "Error." Failure message images include, but are not limited to, failure animations and "×" symbols.

[0213] The third interface includes a fingerprint matching failure prompt interface, a movement trajectory matching failure prompt interface, or a prompt to re-enter the password. The fingerprint matching failure prompt interface may include text prompts such as "Fingerprint matching failed," "Fingerprint matching error," "Input error," "Fingerprint recognition failed," or "Recognition failed," and may also include an "×" icon. The movement trajectory matching failure prompt interface may include text prompts such as "Movement trajectory matching failed," "Movement trajectory matching error," "Input error," "Movement trajectory recognition failed," "Recognition failed," or "Gesture recognition failed," and may also include an "×" icon. The prompt to re-enter the password may include prompts such as "Please re-enter," "Enter again," or "Try again," or may directly display the password input button.

[0214] Figure 13 is a schematic diagram of a third interface presented in response to a second movement trajectory according to an embodiment of this application. The terminal device acquires the user's second movement trajectory "6" on the first interface. Fingerprint matching fails, and a third interface is presented. In Figure 13(a), the third interface displays the failure message "Slide to unlock"; in Figure 13(b), the third interface displays the failure messages "Use face recognition to unlock XX", "Please face the screen to verify your face", and "Use password"; in Figure 13(c), the third interface displays the failure message pattern "×"; in Figure 13(d), the third interface displays the failure message "Please enter password" and a password input button; in Figure 13(e), the third interface displays the failure message "Application fast launch failed, please try again" and a failure message pattern; in Figure 13(f), the third interface displays the failure message "Recognition failed". It should be understood that after the terminal device acquires the user's second movement trajectory on the first interface, any screen different from the first interface that is not unlocked and displayed on the screen can be considered a failure message interface, i.e., the third interface. The third interface is not limited to the examples described above.

[0215] Figure 14 is an exemplary flowchart of another application startup method provided in an embodiment of this application.

[0216] 1410, on the first interface, obtain the third movement trajectory.

[0217] On the first interface of the terminal device, the user's third movement trajectory on the terminal device screen is acquired. The third movement trajectory passes through the fingerprint sensing area of ​​the terminal device.

[0218] For a description of the first interface, please refer to Figure 4. For a description of the third movement trajectory, please refer to Figure 9. This application will not repeat the description.

[0219] 1420, responding to the third movement trajectory, presents the fourth interface.

[0220] In response to the third movement trajectory, a fourth interface is displayed on the terminal device's screen, which is the terminal device's desktop homepage.

[0221] If fingerprint matching is successful but third movement trajectory matching fails, the terminal device can display a fourth interface.

[0222] The home screen of a terminal device is typically the interface a user sees on the screen when they first start the device. This home screen can include one or more of the following: application icons, application folders, application widgets, wallpaper, search bar, bottom navigation bar, and theme animations.

[0223] Figure 15 is a schematic diagram of a fourth interface presented in response to a third movement trajectory according to an embodiment of this application. The terminal device acquires the user's third movement trajectory "8" on the first interface. If fingerprint matching is successful, or if the third movement trajectory matching fails, the fourth interface is presented. In Figure 15(a), the fourth interface includes multiple applications and a bottom navigation bar; in Figure 15(b), the fourth interface includes a search bar and multiple application widgets; in Figure 15(c), the fourth interface includes a search bar, multiple application widgets, and multiple applications; in Figure 15(d), the fourth interface includes multiple applications, application widgets, and a bottom navigation bar; in Figure 15(e), the fourth interface includes multiple applications, a search bar, and a bottom navigation bar; in Figure 15(f), the fourth interface includes a search bar and multiple applications.

[0224] The method for presenting a fourth interface in response to a third movement trajectory provided in this application can also be used for slide-to-unlock on terminal devices, allowing users to securely unlock the device without being aware of the fingerprint module. Compared to traditional slide-to-unlock without security protection, it adds fingerprint verification, improving security and protecting user privacy. Furthermore, compared to the traditional fingerprint-pressing unlock method, this unlocking method is more in line with users' mobile phone usage habits, providing a better interactive and responsive experience. Optionally, slide-to-unlock can also be combined with system desktop switching animations to present richer visual effects, enhancing the user's unlocking interaction experience.

[0225] Figure 16 is an exemplary flowchart of another application startup method provided in an embodiment of this application.

[0226] 1610, on the first interface, obtain the fourth movement trajectory.

[0227] On the first interface of the terminal device, the user's fourth movement trajectory on the terminal device screen is acquired. The fourth movement trajectory passes through the fingerprint sensing area of ​​the terminal device.

[0228] For a description of the first interface, please refer to Figure 4. For a description of the fourth movement trajectory, please refer to Figure 9. This application will not repeat the description.

[0229] 1620, responding to the fourth movement trajectory, presents the fifth interface.

[0230] In response to the fourth movement trajectory, a fifth interface is displayed on the terminal device's screen. The fifth interface is the application interface displayed on the terminal device before the screen is turned off.

[0231] If fingerprint matching is successful but the fourth motion trajectory matching fails, the terminal device can display a fifth interface. This fifth interface represents the application interface displayed on the screen before the screen turned off. For example, if the user was viewing the photo album before the screen turned off, the fifth interface would be the photo album application's interface. If the user was using a chat application before the screen turned off, the fifth interface would be the chat application's interface.

[0232] In one possible implementation scenario, if the time the terminal device is in a screen-off state is greater than a preset time threshold, then if fingerprint matching is successful but movement trajectory matching fails, the terminal device will display a fourth interface; if the time the terminal device is in a screen-off state is less than or equal to the preset time threshold, then if fingerprint matching is successful but movement trajectory matching fails, the terminal device will display a fifth interface.

[0233] Figure 17 is a schematic diagram of presenting a fifth interface in response to a fourth movement trajectory according to an embodiment of this application. The terminal device acquires the user's fourth movement trajectory "L" on the first interface. If fingerprint matching is successful, or if the fourth movement trajectory matching fails, and the screen-off time is less than or equal to a preset time threshold, the fifth interface is presented. In Figure 17(a), the fifth interface is the user interface of the camera application displayed on the screen before the screen turns off; in Figure 17(b), the fifth interface is the user interface of the album application displayed on the screen before the screen turns off; in Figure 17(c), the fifth interface is the user interface of the memo application displayed on the screen before the screen turns off.

[0234] The method for presenting a fifth interface in response to a fourth movement trajectory provided in this application embodiment can also be used for slide-to-unlock on terminal devices, allowing users to securely unlock the device without being aware of the fingerprint module's presence. Compared to traditional slide-to-unlock without security protection, it adds fingerprint verification, improving security and protecting user privacy. Furthermore, compared to the traditional fingerprint-pressing unlock method, this unlocking method is more in line with users' mobile phone usage habits, providing a better interactive and responsive experience. Optionally, slide-to-unlock can also be combined with system desktop switching animations to present richer visual effects, enhancing the user's unlocking interaction experience.

[0235] Figure 18 is an exemplary flowchart of another application startup method provided in an embodiment of this application.

[0236] 1810, on the first interface, obtain the fifth movement trajectory.

[0237] On the first interface of the terminal device, the user's fifth movement trajectory on the terminal device screen is acquired. The fifth movement trajectory passes through the fingerprint sensing area of ​​the terminal device.

[0238] For a description of the first interface, please refer to Figure 4. For a description of the fifth movement trajectory, please refer to Figure 9. This application will not repeat the description.

[0239] At 1820, in response to the fifth movement trajectory, the first interface is displayed.

[0240] In response to the fifth movement trajectory, the first interface is displayed on the screen of the terminal device. The first interface is the interface of the terminal device when the screen is off and locked.

[0241] If fingerprint matching fails, the terminal device can display the first interface, meaning the screen display remains unchanged. For example, if fingerprint matching fails and the fifth movement trajectory matching also fails, the terminal device displays the first interface. Alternatively, if fingerprint matching fails but the fifth movement trajectory matching succeeds, the terminal device displays the first interface.

[0242] Figure 19 is a schematic diagram of presenting a first interface in response to a fifth movement trajectory according to an embodiment of this application. The terminal device obtains the user's fourth movement trajectory "M" on the first interface; fingerprint matching fails, but the first interface is still displayed. Figure 20 is a schematic diagram of presenting a first interface in response to a fifth movement trajectory according to another embodiment of this application. The terminal device obtains the user's fourth movement trajectory "N" on the first interface; fingerprint matching fails, but the first interface is still displayed.

[0243] Figure 21 is an exemplary flowchart of another application launch method provided in an embodiment of this application.

[0244] 2110, Users can enter preset fingerprints and preset movement trajectories.

[0245] Users can register at least one preset fingerprint and at least one preset movement trajectory corresponding to an application while the terminal device is in use. Each preset movement trajectory corresponds to the quick launch of an application. For example, preset movement trajectory "S" corresponds to the quick launch of the photo album application, preset movement trajectory "W" corresponds to the quick launch of the contacts application, and preset movement trajectory "C" corresponds to the quick launch of the music player application.

[0246] In one possible implementation, the process of a user registering a preset fingerprint is as follows: (1) The user opens the settings application on the terminal device; (2) In the settings, find "Security and Privacy" or a similar option; (3) Select "Fingerprint Recognition" or "Fingerprint and Password" or a similar option; (4) The system may ask the user to enter a device password or pattern to confirm identity; (5) The user selects "Add Fingerprint" or a similar option; (6) The user follows the on-screen instructions to gently place their finger on the fingerprint sensor multiple times until the system successfully registers the fingerprint. The fingerprint is not limited to a complete fingerprint, but can also be a part of a fingerprint, such as the fingerprint of the fingertip.

[0247] In one possible implementation, the process of a user entering the relationship between a preset movement trajectory and an application is as follows: (1) The user opens the settings application on the terminal device; (2) In the settings, find the relevant options such as "accessibility" or "gesture control"; (3) Select "add gesture" or a similar option; (4) The user can customize the preset movement trajectory and associated applications. The preset movement trajectory can be customized by drawing letters, numbers or symbols, etc., and the application associated with the preset movement trajectory can be selected, such as "S" associated with the photo album application, "W" associated with the address book application, and "C" associated with the music playback application.

[0248] 2120, the acquisition module collects fingerprints and movement trajectories.

[0249] On the first interface of the terminal device, the terminal device collects the user's fingerprint and the user's movement trajectory on the screen.

[0250] The first interface is the interface of the terminal device in the screen-off and locked state. The screen-off and locked state of the terminal device means that when the user is inactive for a period of time, the device screen will turn off to save power and the screen will be locked to prevent unauthorized access.

[0251] For example, a user's fingerprint can be collected using a fingerprint sensor, or the user's movement trajectory on the screen can be collected using a fingerprint sensor or a TPIC. Optionally, the fingerprint sensor can be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc.

[0252] It should be understood that during the process of a user's finger swiping on the screen, it is not required that all points of the movement trajectory be within the fingerprint sensing area, but the movement trajectory of the finger must pass through the fingerprint sensing area at least once in order to collect fingerprint data and ensure subsequent fingerprint verification.

[0253] In one possible implementation, the terminal device can remind the user that if they want to quickly wake up a specified application while the screen is off and locked, the movement trajectory of their finger must pass through the fingerprint sensing area on the screen, and circle the fingerprint sensing area on the user interface to remind the user, as shown in Figure 22.

[0254] It should be understood that there are no special requirements on the order of collecting movement trajectories and fingerprints in this application embodiment; they can be collected in parallel or sequentially.

[0255] For a detailed description of the movement trajectory, fingerprint sensing area, and movement trajectory recognition area, please refer to the descriptions in Figures 9 to 11, which will not be repeated here.

[0256] 2130, presenting the first interface, second interface, third interface, fourth interface, or fifth interface.

[0257] The user fingerprint collected in step 2120 is matched with the fingerprint entered by the user in step 2110. If the similarity between the fingerprint collected by the terminal device and the preset fingerprint is greater than a first preset matching threshold, the fingerprint match is successful; if the similarity between the fingerprint collected by the terminal device and the preset fingerprint is less than or equal to the first preset matching threshold, the fingerprint match fails. In the case of collecting multiple user fingerprints (e.g., multi-finger gestures), as long as at least one fingerprint has a similarity greater than the first preset matching threshold with the fingerprint entered by the user in step 2110, the fingerprint match is successful; otherwise, the fingerprint match fails.

[0258] The movement trajectory collected in step 2120 is matched with the preset movement trajectory entered by the user in step 2110. If the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is greater than the second preset matching threshold, the movement trajectory matching is successful; if the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is less than or equal to the second preset matching threshold, the movement trajectory matching is unsuccessful.

[0259] Figure 23 is a schematic diagram of the terminal device responding to movement trajectory and presenting different interfaces according to the embodiments of this application. In the first interface, the terminal device acquires the user's movement trajectory "W". If both fingerprint and movement trajectory matching are successful, the second interface is presented. In the first interface, the terminal device acquires the user's movement trajectory "W" but fingerprint matching fails. Regardless of whether the movement trajectory matching is successful, the third or first interface is presented. In the first interface, the terminal device acquires the user's movement trajectory "W" and fingerprint matching is successful but movement trajectory matching fails, presenting the fourth or fifth interface. In this case, the user's operation is equivalent to unlocking the device with a fingerprint while swiping the screen. In one possible implementation scenario, if the terminal device is in a screen-off state for a period longer than a preset time threshold, the fourth interface is presented if fingerprint matching is successful but movement trajectory matching fails. If the terminal device is in a screen-off state for a period less than or equal to the preset time threshold, the fifth interface is presented if fingerprint matching is successful but movement trajectory matching fails.

[0260] For a description of the first interface, second interface, third interface, fourth interface and fifth interface, please refer to Figures 4 to 9, 13, 15, 17 and 19, which will not be repeated in this application.

[0261] In some possible implementations, if the number of fingerprint matching failures exceeds a preset threshold, the terminal device can be set to enter a lost mode.

[0262] Figure 24 is an exemplary flowchart of another application launch method provided in an embodiment of this application.

[0263] 2410, A finger was detected falling on the screen.

[0264] When the terminal device is in a state where the screen is off and locked, and the user's finger lands on the trajectory recognition area or fingerprint sensing area, step 2420 is executed.

[0265] 2420, collect fingerprints and movement trajectories.

[0266] When the device screen is off and locked, users can swipe on the screen using one or more fingers. The device collects the user's fingerprint and the movement trajectory on the screen. In other words, the device can collect the fingerprint of one or more fingers, and the movement trajectory obtained through single-finger or multi-finger operations.

[0267] For example, a fingerprint sensor can be used to collect a user's fingerprint, while a fingerprint sensor or a touch panel integrated circuit (TPIC) can be used to collect the user's movement trajectory on the screen. The fingerprint sensor can be a capacitive fingerprint sensor, an ultrasonic fingerprint sensor, an optical fingerprint sensor, etc.

[0268] In one possible implementation, the terminal device can use a large-area fingerprint sensor to collect the user's fingerprint while capturing the movement trajectory of the user's finger, enabling the system to be unlocked with a single operation and directly launching a pre-set application, thus balancing security and convenience and providing the user with a smooth interactive experience.

[0269] For a detailed description of the movement trajectory, fingerprint sensing area, and movement trajectory recognition area, please refer to the descriptions in Figures 9 to 11, which will not be repeated here.

[0270] 2430, Determine if the fingerprint matches.

[0271] The terminal device matches the user fingerprint collected in step 2420 with a preset fingerprint. If the similarity between the fingerprint collected by the terminal device and the preset fingerprint is greater than a first preset matching threshold, the fingerprint match is successful; if the similarity between the fingerprint collected by the terminal device and the preset fingerprint is less than or equal to the first preset matching threshold, the fingerprint match fails. When multiple user fingerprints are collected, as long as at least one fingerprint has a similarity greater than the first preset matching threshold, the fingerprint match is successful; otherwise, the fingerprint match fails, and the method execution ends.

[0272] 2440, unlock and turn on the screen.

[0273] The terminal device unlocks and the screen lights up.

[0274] 2450, determine if the movement trajectory matches.

[0275] The movement trajectory collected in step 2420 is matched with the preset movement trajectory. If the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is greater than the second preset matching threshold, the movement trajectory matching is successful. If the similarity between the movement trajectory collected by the terminal device and the preset movement trajectory is less than or equal to the second preset matching threshold, the movement trajectory matching fails, and the execution of the method ends.

[0276] It should be understood that there are no special requirements on the order of fingerprint matching (2430) and movement trajectory matching (2450) in this embodiment of the application; they can be matched in parallel or sequentially. This example should not be construed as a limitation of this application.

[0277] 2460, launch the corresponding application.

[0278] Once the user's fingerprint and movement trajectory are successfully matched, the application associated with the movement trajectory is launched. The correspondence between the movement trajectory and the application can be pre-entered by the user or configured by the terminal device before leaving the factory.

[0279] For example, the movement trajectory is "W", which launches the Contacts app; the movement trajectory is "||", which launches the Camera app; and the movement trajectory is "7", which launches the Weather app.

[0280] The application launch method according to embodiments of this application has been described above. The apparatus and device according to embodiments of this application are described below with reference to Figures 25 and 26. It should be understood that the descriptions of the method embodiments correspond to the descriptions of the apparatus embodiments; therefore, any parts not described in detail can be referred to the foregoing method embodiments.

[0281] Figure 25 is a structural example diagram of a computer device 2500 provided in an embodiment of this application. This computer device 2500 may possess the functions of the terminal device in the above method embodiments and can be used to execute the steps performed by the functions of the terminal device in the above method embodiments. This function can be implemented by hardware, or by software or hardware executing corresponding software. The hardware or software includes one or more modules corresponding to the above functions.

[0282] In one possible implementation, the computer device 2500 includes an acquisition module 2510 and a decision module 2520. The acquisition module 2510 and the decision module 2520 are coupled to each other.

[0283] The acquisition module 2510 is used to acquire the user's movement trajectory on the screen of the terminal device under the first interface of the terminal device, and to execute 310 in the method of Figure 3, 1210 in the method of Figure 12, 1410 in the method of Figure 14, 1610 in the method of Figure 16, 1810 in the method of Figure 18, 2120 in the method of Figure 21 and 2420 in the method of Figure 24.

[0284] The decision module 2520 is used to respond to the movement trajectory, display the corresponding interface on the screen, and execute some or all of the steps in the methods shown in Figures 3, 5 to 8, 12 to 21, and 23 to 24.

[0285] Figure 26 illustrates a terminal device 2600 provided in an embodiment of this application. As shown, the terminal device 2600 includes at least one processor 2610 and a transceiver 2620. The processor 2610 is coupled to a memory and is used to execute instructions stored in the memory to control the transceiver 2620 to transmit and / or receive signals.

[0286] Optionally, the terminal device 2600 also includes a memory 2630 for storing instructions.
