Description

[0001] This application is a divisional application of the invention patent application filed on June 8, 2018, with application number 201810588098.5 and invention title "Input Device with Trackball". Technical Field

[0002] This invention relates to a computer mouse. Background Technology

[0003] Computer input devices are ubiquitous in modern culture and are typically used to convert human-induced analog input (e.g., touch, click, movement, touch gestures, button presses, scroll wheel rotations, etc.) into digital signals for computer processing. Input devices can include any means capable of providing data and control signals to a computing system. Some non-limiting examples of input devices include computer mice, trackballs, keyboards, remote controls, game controllers, joysticks, etc. Some non-limiting examples of computing systems include desktop computers, laptops, tablets, smartphones, personal digital assistants (PDAs), wearable devices (e.g., smartwatches, glasses), etc.

[0004] Computer mice are the most commonly used input devices; however, for various reasons, a growing number of users prefer trackballs. For example, trackballs are typically stationary and require less battery power because they generally do not involve power-intensive processing using motion sensors, accelerometers, etc. Since trackballs do not move, they require less surface space and can be used on almost any surface. Some ergonomic advantages include reduced muscle fatigue during prolonged use (e.g., less movement in the shoulders, arms, and wrists) and the ability to be used with both hands in certain situations. Despite these advantages, further improvements in ergonomic design are still needed. Summary of the Invention

[0005] In some embodiments, a computer mouse includes: a housing having a bottom surface; and a trackball disposed within the housing, wherein the bottom surface of the housing may include a first planar region, a second planar region, and a ridge common to both the first and second planar regions and separating the first and second planar regions. The first and second planar regions may lie on different planes. The computer mouse may be configured to rest on a work surface during operation. In some cases, the computer mouse may be configured such that when the first planar region of the bottom surface is parallel to the work surface, the computer mouse tilts at a first angle relative to the work surface, and when the computer mouse is configured such that the second planar region of the bottom surface is parallel to the work surface, the computer mouse tilts at a second angle relative to the work surface. In some embodiments, when the computer mouse is configured such that the first planar region of the bottom surface is parallel to the work surface, the computer mouse tilts at zero degrees relative to the work surface, and when the computer mouse is configured such that the second planar region of the bottom surface is parallel to the work surface, the computer mouse tilts at 20 to 30 degrees relative to the work surface. In some cases, the computer mouse may be combined with a trackball controller.

[0006] In another embodiment, the computer mouse may include a platform coupled to the bottom surface of the housing, wherein the platform rests on a working surface. When the computer mouse is configured such that a first planar region of the bottom surface is parallel to the working surface, the first planar region may rest on and be flush with a first portion of the platform. When the computer mouse is configured such that a second planar region of the bottom surface is parallel to the working surface, the second planar region may rest on and be flush with a second portion of the platform. In some cases, the platform may be held on the working surface as the computer mouse pivots about a ridge between a first angle and a second angle relative to the working surface. In some aspects, the computer mouse may further include: a first set of magnets disposed in a first planar region of the housing; and a second set of magnets disposed in a second planar region of the housing, wherein the platform may be made of metal.

Some embodiments may include a hinge disposed along the ridge on the bottom surface and hingedly coupled to the platform, wherein the platform remains hingedly coupled to the platform as the computer mouse pivots about the ridge between a first angle and a second angle relative to the working surface. The computer mouse may include a scroll wheel, wherein the ridge and the scroll wheel can be linearly offset by 12 to 14 degrees, and in some cases, the ridge can be configured to linearly align with the user's forearm when the user uses the computer mouse.

In some embodiments, the computer mouse may further include a platform coupled to the bottom surface of the housing for resting on the work surface, wherein when the computer mouse is configured such that the first planar region of its bottom surface is parallel to the work surface, the first planar region rests on and is flush with a first portion of the platform, and when the computer mouse is configured such that the second planar region of its bottom surface is parallel to the work surface, the second planar region rests on and is flush with a second portion of the platform. The platform can be held on the work surface as the computer mouse pivots about a ridge between a first angle and a second angle relative to the work surface.

[0010] In another embodiment, the computer mouse may include: a first set of magnets disposed in a first planar region of the housing; and a second set of magnets disposed in a second planar region of the housing, wherein the platform may be made of metal.

The computer mouse may include a trackball and / or a scroll wheel, wherein a ridge may be linearly offset from the scroll wheel by 12 to 14 degrees, and the ridge may be configured to linearly align with the user's forearm when the user uses the computer mouse.

[0011] In some embodiments, a computer mouse includes: a housing having a bottom surface; and a platform coupled to the bottom surface of the housing for resting on a work surface, the platform including a first portion and a second portion, wherein the bottom surface of the housing may include a first planar region, a second planar region, and a ridge common to both the first and second planar regions and separating the first and second planar regions.

[0029] Embodiments of the present invention generally relate to input devices. More specifically, some embodiments relate to adjustable computer input devices with a trackball.

[0030] In the following description, numerous examples and details are set forth for illustrative purposes to provide an understanding of embodiments of the invention. However, it will be apparent to those skilled in the art that certain embodiments may be practiced without some of these details, or by modifications or equivalents thereof.

[0031] In some implementations, the input device (e.g., a computer mouse) may include a trackball and may be adjustable to accommodate different hand positions, thereby improving ergonomics. The bottom surface of the input device rests on the working surface and may be wedge-shaped to include a first planar region and a second planar region located on different planes separated by a common ridge. The input device may be configured to rest on the first planar region to position the input device at a first angle (e.g., zero degrees) relative to the surface, or the input device may be tilted such that it rests on the second planar region to position the input device at an angle (e.g., 20 degrees), thereby reducing strain on the user's wrist. The input device may include a platform that can serve as an interface between the bottom surface of the input device and the working surface, such as those discussed further below. Figure 4A and Figure 4B As shown. For example, the platform can be connected via a magnet (see, for example, see...). Figure 3 ), hinges (for example, see Figure 5 A friction-fit connection is made to the bottom surface of the input device, such that a first planar region or a second planar region rests on the platform, allowing the input device to be configured at different angles relative to the working surface. In some cases, the user can tilt the input device back and forth along the ridge between the first and second planar regions on the platform. Some embodiments also include ergonomic enhancements, which include a ridge and rollers offset by a preferred distance (e.g., 12 to 14 degrees), and the ridge separating the first and second planar regions is linearly aligned with the user's forearm, which can reduce muscle fatigue and certain repetitive use injuries. Many variations, modifications, and alternative embodiments will be understood by those skilled in the art, some of which are presented in the following description and figures.

[0032] Figure 1AAn adjustable computer input device 100 with a trackball according to certain embodiments is shown. The input device 100 may include a housing 110, a trackball 120, a scroll wheel 130, a left button 122, a right button 124, a back / forward button 132 (also referred to as a “side” button 132 or simply “button 132”), a main selection button 133, a precision tracking button 134, a light-emitting diode (LED) 136, and a platform 140 (not shown in this view). The housing 110 may be a base that can accommodate, support, and contain some or all of the components of the input device 100 and serve as the main user interface to support the user's hand and contact the work surface (directly or indirectly through the platform 140), as will be understood by those skilled in the art. Many embodiments described herein refer to input devices. It should be understood that, except when referring to “conventional” computer mice, etc., the input devices described in the embodiments of this disclosure may include computer mice with trackballs, computer input devices, trackball devices, etc.

[0033] The trackball 120 may include any suitable trackball tracking technology, including mechanical tracking systems, optical tracking systems, infrared (IR) tracking systems, laser tracking systems, etc. A mechanical tracking system may include a trackball supported by two or more vertical encoding axes and a third support track that physically tracks the movement of the ball and translates that movement into, for example, the movement of a cursor on a digital display (e.g., a computer monitor). Optical and IR tracking systems may use various LEDs (e.g., red, IR, etc.) that can reflect light from the surface of the trackball onto a complementary metal-oxide-semiconductor (CMOS) sensor (or other suitable sensor) to track the movement of the trackball. The optical and IR sensors, in addition to the trackball, cannot have moving parts. The system may employ other elements including trackball holding hardware, one or more lenses, etc. A laser tracking system may employ a laser diode that generates a beam of light that can be focused onto the surface of the trackball, which reflects the light back to the sensor that calculates the motion. Many variations, modifications, and alternative implementations will be understood by those skilled in the art.

[0034] The scroll wheel 130 may include any suitable functionality, including but not limited to freewheel scrolling, ratchet scrolling, clutch scrolling, tilt functionality, click capability (e.g., pressable to contact a sensor to obtain a "button press"), etc. The left button 122 and right button 124 may include separate keypads or may be integrated into the housing, as discussed in U.S. Patent Application 15 / 453,744, the entire contents of which are incorporated herein by reference for all purposes. Any number of buttons, touch sensors, or other user interface elements may be incorporated into the input device 100. For example, some embodiments may include a one-dimensional touch-sensitive slider or a two-dimensional touch-sensitive touchpad. Button 132 may be preset to have a specific function (e.g., back / forward, next page, previous page, etc.) or may be any suitable function that can be assigned to the user.

[0035] The main selection button 133 can be used to switch between multiple operating systems and cross-platform operation on multiple main computing devices. For example, the input device 100 can be used with running... The first main computing device running the operating system and running Mac The operating system wirelessly pairs a second master computing device, wherein the master selection button 133 causes the input device 100 to switch control between the first and second master devices. This is further discussed in application 14 / 884,381, the entire contents of which are incorporated herein by reference for all purposes. In some embodiments, such as those described in U.S. Patent Application 15 / 226,770, the entire contents of which are incorporated herein by reference for all purposes, the input device 100 may be “mobile for use.” The precision tracking button 134 (or “button 134”) may be configured to enhance trackball tracking by varying the tracking speed of the sensor to increase dots per inch (DPI) performance, which may be advantageous for certain applications. The LED 136 may be designated to illuminate for any suitable purpose, including indicating master switching, DPI setting, charging indicator, etc. The input device 100 may use any suitable wireless connectivity—including Bluetooth Low Energy Logitech IR or other suitable radio frequencies (RF) – and connected to one or more main computing devices, as will be understood by those skilled in the art.

[0036] Figure 1B An adjustable computer input device 100 with a trackball displayed in a neutral configuration, according to some embodiments, is shown. A platform 140 and a charging port 138 can be observed from this perspective view. The charging port 138 can be a coupling device via hardwired connection (e.g., USB-C, USB-Mini, USB-U, USB-3, FireWire, etc.). or Interfaces for charging one or more energy storage devices (e.g., batteries) disposed in housing 110, such as connectors; data ports for communicating with a main computing device (e.g., a portable computer, a desktop computer, a tablet computer, etc.); or combinations thereof. See at least the following references. Figure 3 As shown and described, the platform 140 supports the bottom of the input device 100, including a first planar region 314 and a second planar region 316. (Return to reference) Figure 1B The input device 100 is configured such that the second planar region 316 of the bottom portion of the housing 110 rests on the platform 140, thereby causing the input device 100 to tilt at 0 degrees from its resting working surface. Figure 1C The diagram illustrates an input device 100 configured such that a first planar region 314 of the bottom portion of the housing 110 rests on a platform 140, causing the input device 100 to tilt at a 20-degree angle from its resting working surface. In some embodiments, other angles may be achieved. For example, the bottom surface (e.g., the first planar region 314) may be configured to allow the input device 100 to tilt at smaller angles (e.g., 5 to 15 degrees) and larger angles (e.g., 25, 30, 35 degrees, etc.). Those skilled in the art will benefit from this disclosure to understand its many variations, modifications, and alternative implementations.

[0037] The various examples, descriptions, and corresponding figures described throughout this document are collectively referred to as a main computing device without explicitly specifying a type (e.g., a portable computer). It should be understood that a main computer can be any suitable computing device, including but not limited to desktop computers, portable computers, tablet computers or “tablet” computers, smartphones, personal digital assistants, wearable devices (e.g., smartwatches, smart glasses), smart devices, vehicles, or any other suitable computing device. A main computer may include a machine-readable medium (not shown) configured to store computer code, such as mouse driver software, which can be executed by a processor (e.g., see processor 210) to control various aspects of the main computer via input device 100.

[0038] In some embodiments, the input device 100 may be configured to provide control signals for motion tracking (e.g., xy motion based on manual trackball manipulation), touch and / or gesture detection (e.g., on a touch-sensitive portion of the input device 100), orientation detection, power management capabilities, input detection (e.g., buttons, scroll wheels, etc.), output functions (e.g., LED control, haptic feedback, etc.), or any of a number of additional features as understood by one of ordinary skill in the art.

[0039] Figure 2A simplified block diagram of a system 200 for operating an input device 100 according to certain embodiments is shown. System 200 may include a processor 210, an input detection block 220, a motion tracking block 230, a power management block 240, and a communication block 250. Each of system blocks 220 to 250 may be in electrical communication with the processor 210. System 200 may also include additional systems, not shown or discussed, to avoid obscuring novel features described herein.

[0040] In some embodiments, processor 210 may include one or more microprocessors (μCs) and may be configured to control the operation of system 200. Alternatively, processor 210 may include one or more microcontrollers (MCUs), digital signal processors (DSPs), etc., having supporting hardware, firmware (e.g., memory, programmable I / O, etc.) and / or software, as will be understood by those skilled in the art. Alternatively, MCUs, μCs, DSPs, etc., may be configured in other system blocks of system 200. For example, communication block 250 may include a local processor to control communication with the host computing device (e.g., via Bluetooth, Bluetooth LE, RF, IR, hardwired, ZigBee, Z-Wave, Logitech Unifying, or other communication protocols). In some embodiments, multiple processors may enable additional performance characteristics (e.g., speed and bandwidth) in system 200. It should be noted that while multiple processors may improve system performance, they are not necessary and are not critically related to the operation of the embodiments described herein.

[0041] In some aspects, input detection block 220 can control the detection of buttons (e.g., left / right buttons or "main" buttons 122, 124; buttons 132, 134; scroll wheel 130, etc.), scroll wheel and / or trackball manipulation (e.g., rotation detection), sliders, switches, touch sensors (e.g., one-dimensional and / or two-dimensional touchpads), etc. In some embodiments, input detection block 220 can detect when a keypad, button, scroll wheel, etc., is pressed with sufficient force, causing the keypad, button, scroll wheel to contact and activate a force sensor (e.g., an actuator). The force sensor can generate a corresponding control signal (e.g., a human-machine interface (HID) signal) to control a main computing device communicatively coupled to input device 100 (e.g., "left click" exemplified on a computer). Alternatively, the functionality of input detection block 220 can be included in or combined with processor 210.

[0042] In some embodiments, the input detection block 220 can detect touches or touch gestures on one or more touch-sensitive surfaces on the input device 100. The input detection block 220 may include one or more touch-sensitive surfaces or touch sensors. Touch sensors typically include sensing elements adapted to detect signals such as direct contact, electromagnetic or electrostatic fields, or beams of electromagnetic radiation. Touch sensors can typically detect changes in received signals, the presence of a signal, or the absence of a signal. Touch sensors may include a source for emitting the detected signal, or the signal may be generated by a secondary source. Touch sensors may be configured to detect the presence of an object at a distance from a reference area or point (e.g., <5 mm), the presence of an object in contact with the reference area or point, or a combination thereof. Some embodiments of the input device 100 may or may not utilize touch detection or touch sensing capabilities.

[0043] Input detection block 220 may include touch and / or proximity sensing capabilities. Some examples of touch / proximity sensor types may include, but are not limited to, resistive sensors (e.g., carbon-loaded standard air-gap 4-wire plastics with different electrical characteristics depending on pressure (FSR), interpolated FSR, etc.), capacitive sensors (e.g., surface capacitance, self-capacitance, mutual capacitance, etc.), optical sensors (e.g., IR grating matrix, laser-based diodes coupled to a photodetector that measures the transit time of the optical path, etc.), acoustic sensors (e.g., piezoelectric buzzers coupled to microphones to detect modifications to wave propagation patterns associated with the touch point, etc.).

[0044] The motion tracking block 230 can be configured to track the movement of the trackball 120 on the input device 100. In some embodiments, the motion tracking block 230 can track the movement of the trackball 120 via any suitable tracking system, including but not limited to mechanical tracking systems, optical tracking systems, IR tracking systems, laser tracking systems, etc., as referred to above. Figure 1A Further discussion is needed. In alternative embodiments, the input device 100 can also utilize additional motion tracking hardware to track the movement of the input device 100 along the underlying working surface. In such embodiments, the motion tracking block 230 can use an imaging array of optical sensors, such as LEDs or photodiodes, to detect the movement of the input device 100 relative to the underlying surface. The input device 100 may optionally include motion tracking hardware utilizing coherent (laser) light. In some embodiments, one or more optical sensors are disposed on the bottom side of the input device 100 (not shown). The motion tracking block 230 can provide position data (e.g., XY coordinate data) or lift detection data. For example, the optical sensors can detect when the user lifts the input device 100 off the working surface and can send this data to the processor 210 for further processing.

[0045] In some implementations, accelerometers can be used for motion detection. Accelerometers can be electromechanical devices (e.g., microelectromechanical systems (MEMS) devices) configured to measure accelerating forces (e.g., static and dynamic forces). One or more accelerometers can be used to detect three-dimensional (3D) positioning. For example, 3D tracking can utilize a triaxial accelerometer or two biaxial accelerometers (e.g., in a "3D air mouse"). Accelerometers can further determine whether the input device 130 has been lifted off the surface and provide motion data that may include the velocity, physical orientation, and acceleration of the input device 100. In some implementations, gyroscopes can be used instead of or in combination with accelerometers to determine motion or the orientation of the input device.

[0046] In some implementations, one or more accelerometers and / or gyroscopes may be incorporated into the input device 100 to detect when the input device 100 is configured in a neutral configuration (see, for example, see...). Figure 4A ) or tilted configuration (see, for example, see Figure 4B This can be useful, for example, to notify users that they may want to switch from a neutral to a tilted configuration to reduce wrist strain after prolonged use (e.g., more than one hour of use). In some cases, notifications can be performed via sound, LEDs, haptic feedback, or other feedback mechanisms or combinations thereof on the input device 100, through software operating on the display of the main computing device. Touch detection (e.g., capacitive sensing), biometrics, or supplementary devices (e.g., a webcam) can be used to detect when a user is engaging the input device to determine usage time and whether a switch in orientation (between neutral and tilted orientation) should be suggested. Many variations, modifications, and alternative implementations will be appreciated by those skilled in the art.

[0047] Power management block 240 can be configured to manage power distribution, recharging, power efficiency, etc., for input device 100. In some embodiments, power management block 240 may include a battery (not shown), a USB-based charging system for the battery (not shown), power management devices (e.g., a low-dropout regulator—not shown), and a power grid within system 200 to supply power to each subsystem (e.g., communication block 250, etc.). In some embodiments, the functionality provided by power management block 240 may be incorporated into processor 210. Alternatively, some embodiments may not include a dedicated power management block. For example, functional aspects of power management block 240 may be included in or combined with another block (e.g., processor 210).

[0048] According to some implementations, communication module 250 may be configured to provide the ability to communicate with a host computing device or other devices and / or peripheral devices. Communication module 250 may be configured to provide wireless connectivity (e.g., radio frequency (RF), Bluetooth, BLE, IR, ZigBee, Z-Wave, Logitech Unifying, etc.) to the host computer or other wireless devices. System 200 may include a hardwired connection (e.g., USB, FireWire, etc.) to the host computer. For example, input device 100 may be configured to receive a Universal Serial Bus (USB) cable to enable bidirectional electronic communication with the host computer or other external devices. Some implementations may utilize different types of cables or connection protocol standards to establish hardwired communication with other entities.

[0049] While some systems may not be explicitly discussed, they should be considered as part of system 200, as will be understood by those skilled in the art. For example, system 200 may include a bus system for transmitting power and / or data to and from different systems therein. In some embodiments, system 200 may include a storage subsystem (not shown). The storage subsystem may store one or more software programs to be executed by a processor (e.g., in processor 210). It should be understood that “software” can refer to a sequence of instructions that, when executed by a processing unit (e.g., processor, processing device, etc.), causes system 200 to perform certain operations of the software program. These instructions may be stored as firmware residing in read-only memory (ROM) and / or an application stored in media memory, which may be read into memory for processing by the processing device. The software may be implemented as a single program or a collection of single programs and may be stored in non-volatile memory and copied, in whole or in part, to volatile working memory during program execution. The processing device may retrieve program instructions to be executed from the storage subsystem to perform various operations as described herein (e.g., software-controlled automatic spring adjustment, etc.).

[0050] It should be understood that System 200 is intended to be illustrative, and many variations and modifications are possible, as will be understood by those skilled in the art. System 200 may include other functions or capabilities not specifically described herein (e.g., mobile phone, Global Positioning System (GPS), power management, one or more cameras, various connection ports for connecting external devices or accessories, etc.). While System 200 is described with reference to specific blocks (e.g., input detection block 220), it should be understood that these blocks are defined for understanding certain embodiments of the invention and do not imply that the embodiments are limited to a specific physical arrangement of the parts. The individual blocks do not need to correspond to physically different components. Blocks may be configured to perform various operations, for example, by programming a processor or providing appropriate processing, and the various blocks may or may not be reconfigurable depending on how the initial configuration was obtained. Embodiments of the invention can be implemented in a variety of devices, including electronic devices implemented using any combination of circuitry and software. Furthermore, aspects and / or portions of System 200 may be combined with or operated in combination with other subsystems as informed by the design. For example, power management 240 may be combined with processor 210 rather than being used as a separate entity.

[0051] Figure 3 A multi-planar bottom surface and platform structure according to certain embodiments are illustrated. Input device 300 may include housing 310 and a bottom surface of housing 310, the bottom surface including a first planar region 314, a second planar region 316, and a ridge 312, the ridge 312 being shared by the first planar region 314 and the second planar region 316 and separating the first planar region 314 from the second planar region 316. Platform 340 is configured to be coupled to one of the first and second planar regions according to the configuration of input device 300. For example, in a neutral configuration, the second planar region 316 is coupled to platform 340, such as... Figure 4A As shown. When in the tilted configuration, the first planar region 314 is connected to the platform 340, as... Figure 4B As shown. In this way, the first planar region 314 can be located on a different plane than the second planar region 316 to achieve different tilts of the input device 300.

[0052] In some aspects, the ridge 312 may include a coupling guide 318 disposed thereon to receive a portion 342 of the platform 340, which may be referred to as a protrusion 342. The coupling guide 318 can be used to assist in aligning the platform 340 onto the bottom surface of the input device 300. For example, configuring the protrusion 342 to fit within the coupling guide 318 can properly align the platform 340 with the bottom portion of the housing defined by the first planar region 314 and the second planar region 316. In some cases, as the input device 300 pivots about the ridge located between the first planar region 314 and the second planar region 316, the coupling guide 318 retains the protrusion 342 coupled to the platform 340, such as... Figures 4A to 4B As shown. The first planar region 314 may correspond to a first angle (e.g., 20 degrees) relative to the working surface, and the second planar region 316 may correspond to a second angle (e.g., 0 degrees) relative to the working surface. The platform 340 may be made of metal (e.g., steel, nickel, or other ferromagnetic metal), plastic, or other suitable compound. In some cases, the connecting guide 318 may be a recess along the ridge 312.

[0053] Some implementations may also include a magnet 350 located on a first platform 314 and a magnet 352 located on a second platform 316, magnetically coupled to the platform being made of a ferromagnetic material (e.g., steel). In some aspects, such as in the case of a platform made of a non-ferromagnetic material (e.g., aluminum, plastic, etc.), additional magnets may be used to magnetically couple to magnets on the bottom surface of the input device 300. For example, a magnet 354 may be embedded in a position on the platform 340 such that when the input device 300 is placed in an inclined configuration (e.g., tilted at 20 degrees), the magnet 354 is magnetically coupled to the magnet 350 in the first planar region 314. Similarly, a magnet 356 may be embedded in a position on the platform 340 such that when the input device 300 is placed in a neutral configuration (e.g., tilted at 0 degrees), the magnet 356 is magnetically coupled to the magnet 532 in the second planar region 316. Magnets 350, 352, 354, and 356 can each be a single magnet or a group of magnets (e.g., multiple magnets).

[0054] Magnets can be used to increase the holding force (magnetic force) between the platform 340 and the bottom of the input device 300 (i.e., the first planar region 314 / second planar region 316), so that users who place their hands on the input device 300 during use will not unintentionally cause switching between neutral and tilted configurations. That is, according to some embodiments, the weight of a user's hand typically does not provide sufficient force to switch configurations during normal use. Thus, the user will have to apply additional force to pivot the input device 300 between the configurations. The amount of force required to switch between neutral and tilted configurations can depend on the number of magnets used and their position on the input device and / or platform 340 (e.g., the further the magnets 350 / 352 are positioned from the ridge 312, the greater the force required to break the magnetic coupling between the magnets and the platform). In some embodiments, the number and / or position of the magnets are designed such that a force of approximately 700g toward one side or the other of the input device 300 causes the input device 300 to switch from one configuration (e.g., a neutral configuration) to another configuration (e.g., a tilted configuration). Studies have shown that breaking the magnetic bond between the magnet and the platform to switch from one configuration to another preferably requires approximately 650g to 750g. In embodiments where the magnetic bond is approximately 400g to 500g, the user experience tends to feel that the switch is too easy, which may lead to unintentional transitions between configurations. In embodiments where the magnetic bond (i.e., the strength of the bond between the magnet and the platform) is approximately 800g to 900g, the user experience tends to feel that the transition is too difficult (requiring too much force) to make the transition between configurations. The weight of an average-sized hand provides approximately 200g to 300g of force (typically ~250g), so some exemplary embodiments can be configured to receive an additional 400g (total 700g) before overcoming the magnetic bond. Those skilled in the art will understand its many variations, modifications, and alternative implementations.

[0055] Alternatively or additionally, other coupling means may be used to attach the bottom of housing 310 to platform 340. For example, certain reusable adhesives (e.g., glue, rubber, tape, etc.) may be used on the bottom surface of housing 310 (e.g., on the first planar region 314 / second planar region 316), on platform 340, or on both the bottom surface and platform 340. Some embodiments may utilize hardware such as quick-release tabs to achieve and release the coupling between platform 340 and one of the first planar regions 314 or second planar regions 316 in one step. In some cases, during normal use (e.g., when the user rests their hands on input device 300), frictional engagement (e.g., frictional engagement between protrusion 342 and coupling guide 318) may provide sufficient friction to keep the input device in its current configuration (e.g., neutral or tilted configuration). In some implementations, a hinge (e.g., along the ridge 312) can be used to make the connection between the platform 340 and the housing 310 more durable, while still allowing the input device 300 to pivot between configurations. The hinge can also provide sufficient friction to allow any number of tilt angles of the input device 300 to be achieved, because the friction is strong enough to hold the input device 300 in place under normal operating use (e.g., under the weight of the user's hand), as shown below. Figure 5 Further described. In alternative embodiments, three planar regions may be employed. For example, the middle planar region may provide a third angle relative to the working surface, allowing the input device 300 to be configured with three different tilt angles (e.g., 0 degrees, 20 degrees, and 30 degrees). Many variations, modifications, and alternative embodiments will be understood by those skilled in the art. It should be noted that the input device 300 may include the input device 100 or throughout this disclosure (e.g., from...). Figures 1A to 9 Any other input device described herein, including some or all of its features (e.g., scroll wheel 130, buttons 122, 124, etc.) and operational characteristics (e.g., pivoting between a neutral and tilt configuration), or input device 100 or throughout this disclosure (e.g., from...). Figures 1A to 9 Any other input device described may include some or all of the features and operating characteristics of input device 300 such that any inventive concept shown and described in the drawings will be understood by one of ordinary skill in the art, and thus the disclosure may be mixed and matched.

[0056] Figure 4AAn input device 400 arranged in a neutral configuration according to certain embodiments is shown. The input device 400 is shown in a simplified outline in the upper figure to depict how the housing 410 is configured relative to the platform 440 and the underlying working surface. The lower figure presents a more detailed visual illustration of different views of the relationship between the platform 440 and the housing 410. Referring to this outline view, the platform 440 may be coupled to the bottom portion of the housing 410 at a second planar region 416, thereby placing the input device 400 in a neutral configuration. That is, the second planar region 416 rests on and is flush with a portion of the platform 440 and configured parallel to the working surface. As described above, the ridge 412 may be a pivot point when the housing 410 pivots between the neutral and tilted configurations. The ridge 412 may include a coupling guide 418 to receive a protrusion 442, which can be used in either configuration to properly align the platform 440 with the bottom of the housing 410, as referenced above. Figure 3 Further discussion is needed. In some embodiments, the protrusion 442 and the connecting guide 418 may be omitted. See also... Figure 4A As shown in the figure below, the second planar region 416 is connected to the platform 440 such that the input device 400 is in a neutral configuration (e.g., at a zero-degree angle relative to the platform 440 and / or the working surface below), and a portion of the platform 440 does not contact the first planar region 414, which can expose the lower side of the housing 410 (i.e., the first planar region 414).

[0057] Figure 4B An input device 400 arranged in a tilted configuration according to certain embodiments is shown. Similar to... Figure 4A Input device 400 Figure 4B The figure above shows a simplified outline to depict how the housing 410 is configured relative to the platform 440 and the working surface below. Figure 4B The following diagram presents a more detailed visual illustration of the relationship between platform 440 and housing 410 from different perspectives. (See reference...) Figure 4B The outline diagram shows that platform 440 can be coupled to the bottom portion of housing 410 at a first planar region 414, thereby placing input device 400 in an inclined configuration. That is, the first planar region 414 rests on and is flush with a portion of platform 440 and configured parallel to the working surface. As described above, ridge 412 may include coupling guide 418 to receive protrusion 442, which can be used to properly align platform 440 with the bottom of housing 410 in either configuration. In some embodiments, protrusion 442 and coupling guide 418 may be omitted. (Refer to...) Figure 4BAs shown in the figure below, the first planar region 414 is coupled to the platform 440 such that the input device 400 is positioned in an inclined configuration (e.g., at a 20-degree angle relative to the platform 440 and / or the working surface below), and a portion of the platform 440 does not contact the second planar region 416, which exposes the lower side of the housing 410 (i.e., the second planar region 416). It should be noted that although 0-degree and 20-degree inclinations are described in the various embodiments herein, those skilled in the art will benefit from this disclosure to understand that other designs with different inclinations (e.g., 0 to 30 degrees) are possible.

[0058] Figure 5 An adjustable input device 500 with a hinge structure 550 and a trackball according to some embodiments is shown. The input device 500 may be similar to input devices 100, 300, and 400, except that a hinge structure 550 is added along a ridge-like portion of the lower side of the housing 510. The hinge structure 550 may be configured to attach a platform 540 to the bottom side of the housing 510, but still allow the platform 540 to rotate freely (or with resistance) between a neutral configuration and a tilted configuration as described above (i.e., the platform 540 may be hinged to the ridge-like portion). The hinge structure 550 may include a flange 556 connecting the hinge structure 550 to the housing 510 (e.g., via screws, pins, etc.), a cylindrical portion 552, and a rotatable portion 554 rotatably connected to the cylindrical portion 552 and fixedly connected to the platform 540, such as... Figure 5 As shown. In some cases, the hinge structure 550 may provide frictional resistance for rotation that may be greater than the force exerted by a user placing their hand on the input device 500, to prevent the input device 500 from unintentionally pivoting between a neutral configuration and a tilted configuration. In some aspects, the friction may also be low enough that a user can switch between the configurations without requiring excessive force. For example, the friction may be set such that a user needs to exert a total force of approximately 700g to switch the device's configuration (note that a typical hand provides 250g of force, so the additional force felt by the user may be close to 450g, as those skilled in the art will understand). Thus, the input device 500 can be configured with many different tilt angles because the frictional resistance for rotation may be high enough to accommodate the weight of a user's hand at any tilt angle from 0 degrees to 20 degrees (or more, depending on the tilt angle of the underlying planar region). The hinge structure 550 may be embedded within the housing 510 (e.g., not protruding) such that the platform 540 can still be flush with the bottom of the housing 510 (i.e., against the first planar region or the second planar region). In some implementations, such as reference Figure 3 As discussed, magnets, adhesives, mechanical latches / releases, etc., can be used.

[0059] Ergonomic advantages

[0060] Poor posture has been identified as a key risk factor for repetitive strain injury (RSI). One of the goals of ergonomics is to configure interface devices, workstations, etc., towards more natural postures and body orientations. For example, a traditional mouse requires the user's hand to be placed in a horizontal, palm-down position. However, some embodiments of the present invention can be configured to tilt, thereby allowing the forearm to rotate clockwise (i.e., turn the palm over), which can reduce stress on the muscles that hold the forearm bones (i.e., the radius and ulna) (i.e., the radial and ulnar muscles). See below for reference. Figures 6 to 8B The various ergonomic advantages of the various embodiments described herein are shown and described.

[0061] Figure 6 Various ergonomic aspects of different user wrist orientations are illustrated. User 600 is shown holding a typical computer mouse device 614 with palm-down hand 612. In this configuration, the tibia 602 and ulna 604 at the user's wrist 610 position the palm downwards at an angle of 0 to 10 degrees relative to the underlying working surface. This orientation may be satisfactory for long-term use but may be affected by RSI (Resistant Stability).

[0062] According to some embodiments, user 620 is shown holding an input device 634 in an inclined configuration (e.g., similar to input devices 100, 300, 400) with the user's hand 632. In this configuration, the tibia 622 and ulna 624 are tilted less at the user's wrist 630 at an angle of 20 to 50 degrees relative to the underlying working surface (i.e., tilted more toward a neutral orientation). This orientation may be very satisfactory for long-term use and may be less susceptible to RSI than a conventional mouse.

[0063] User 640 is shown holding their hand 652 in a neutral configuration, as would be during hand shaking. In this configuration, the tibia 642 and ulna 644 are neutral at the user's wrist 650 at an angle of 50 to 90 degrees relative to the underlying working surface (e.g., halfway between palm completely down and palm completely up). This orientation may be optimal and even less susceptible to RSI, but is generally less practical for computer input devices. However, some embodiments may include a planar surface area greater than 20 degrees from the underlying working surface, and some embodiments may be 30 to 40 degrees or more. Many variations, modifications, and alternative embodiments will be appreciated by those skilled in the art.

[0064] In addition to configuring the input device to place the user's hands in a more neutral position, other ergonomic improvements can be made to reduce stress on the aforementioned muscles. For example, keeping the hand aligned with the forearm can further reduce the likelihood of RSI (Restricted Strain Injury). Figure 7A and Figure 7B An input device 720 with an ergonomic design that maintains proper wrist alignment according to certain embodiments is shown. Figure 7A A top view of the user 700's hand-engaged input device 720 is shown. Figure 7B A bottom view of the same input device 720 is shown. When the input device 720 is engaged, the user 700's wrist 710 is aligned (e.g., parallel) with the ridge 730, which is the pivot point between the neutral configuration and the tilting operation configuration described above (see, for example, [reference]). Figures 3 to 4B The alignment between the wrist 710 and the ridge 730 places the user's hand in a more neutral configuration relative to the forearm, thereby improving ergonomics, reducing wrist stress, and minimizing potential RSI events. In another embodiment, the ridge 730 and the roller may be linearly offset by 12 to 14 degrees to improve comfort and feel and reduce pressure on the user's thumb.

[0065] Typically, moving a traditional mouse or trackball device involves five key muscles, and each muscle may be involved in potential injuries (e.g., epicondylitis). The less these muscles are used, the more relaxed and comfortable the user is likely to be. These muscles can include the upper trapezius, wrist extensors, ulnar flexors, thumb abductors, and thumb adductors.

[0066] Figure 8A Various ergonomic advantages of using a tilted trackball input device at workstation 800 according to certain embodiments are shown. Figure 8A This includes a keyboard 804 and an input device 806 (e.g., such as...). Figures 3 to 4B User 802 operates the device using a tilted trackball (as shown). The muscles shown include the upper trapezius 810, wrist extensor 820, ulnar flexor 830, abductor pollicis 840, and adductor pollicis 850. The tilted trackball device (e.g., as shown) is used... Figures 3 to 4B (As shown) Using a non-conventional mouse (e.g., one with a zero-degree tilt relative to the work surface below) can significantly reduce muscle fatigue and the resulting RSI. For example... Figure 8A As shown, muscle activity may be reduced by up to 35% for the upper trapezius 810, wrist extensor 820, ulnar flexor 830, and adductor thumb 850, and wrist and hand position may be improved by up to 50%. However, in some cases, the use of the abductor thumb 840 may be slightly increased because the thumb typically engages the trackball device more than in a conventional mouse.

[0067] When using a conventional mouse, a user's wrist can rest on the work surface for hours on end. Over time, this pressure can cause pain and, in some cases, carpal tunnel syndrome, a repetitive strain injury. One solution to avoid this pain is to eliminate pressure on the wrist as much as possible. Trackball designs (in some implementations) offer a good solution to this problem because they are ergonomically designed and use a static base (for thumb movement only) to allow the wrist to relax and rest. Figure 8B This illustrates how a tilted trackball controller transfers most of the pressure to the palm and very little to the wrist. In contrast, most of the pressure (shown as a cross-shaded pattern) would likely be on the wrist in a conventional mouse design.

[0068] Figure 9 This illustrates how, according to certain embodiments, wedges can be used to increase the tilt of an input device relative to a working surface. In the upper figure, wedge 920 can be placed below input device 910, shown in a zero-degree neutral configuration, to increase its tilt by 10 degrees relative to the underlying surface, resulting in a total tilt of 10 degrees. Similarly, in the lower figure, wedge 940 can be placed below input device 930, shown in a 20-degree tilt configuration, to increase its tilt by 10 degrees relative to the underlying surface, resulting in a total tilt of 30 degrees. Different wedges with different angles can be used. The wedges can be frictionally or adhesively attached to the bottom of input devices 910, 930 (or, as described herein, in any embodiment). The wedges can be made of metal, rubber, plastic, or other suitable compounds. Many variations, modifications, and alternative embodiments will be appreciated by those skilled in the art.

[0069] Typical system environment

[0070] Figure 10 This is a simplified diagram of a computer system 1000 incorporating an input device according to certain embodiments. The computer system 1000 may include a computer 1110, a monitor 1120, an input device 1130, and a keyboard 1140. In some embodiments, the input device 1130 may be a computer mouse, a trackball (as shown), a remote control, a game controller (e.g., a gamepad, joystick, game controller, etc.), a mobile device, or any other suitable device that can be used to convert analog input into digital signals for computer processing. For the computer system 1000, the input device 1130 may be configured to control various aspects of the computer 1110 and the monitor 1120.

[0071] Computer 1110 can be any suitable computing device, including but not limited to desktop computers, portable computers, tablet computers or “tablet” computers, smartphones, PDAs, wearable devices (e.g., smartwatches, smart glasses), etc. In some embodiments, input device 1130 may be configured to provide control signals for motion tracking (e.g., xy motion on a planar surface, “three-dimensional aerial” motion, etc.), touch and / or gesture detection, lift detection, orientation detection, power management capabilities, input detection (e.g., buttons, scroll wheels, etc.), output functions (e.g., LED control, haptic feedback, etc.), or any of a number of additional features that a person skilled in the art would understand. Computer 1110 may include a machine-readable medium (not shown) configured to store computer code, such as mouse driver software, wherein the computer code is executable by a processor of computer 1110 (e.g., see processor 210) to control various aspects of computer 1110 via input device 1130 and / or keyboard 1140. The various embodiments described herein generally refer to the input device 1130 as a computer mouse or similar input device, but it should be understood that the input device 1130 can be any suitable input / output (I / O) device (e.g., user interface device, control device, input unit, etc.) that can be adapted to utilize the novel embodiments described and / or contemplated herein.

[0072] In some implementations, as described herein, software operating on the main computing device (computer 1110) may include various optimizations to improve the user experience (UX) when a user uses an input device (e.g., trackball device 1130). For example, UX software operating on computer 1110 may inform the user when in a particular configuration (e.g., 0 degrees – see example). Figure 4A Spend a specific amount of time (e.g., 5 hours) and suggest they switch to the second configuration (e.g., 20 degrees – see example). Figure 4B In some cases, the software can alert the user (by displaying a message on the monitor) how much time they have spent in one configuration and / or another. An accelerometer and / or gyroscope can be used (see, for example...). Figure 2 The motion tracking module 230) determines the current configuration, but other methods for determining the current configuration are also possible (e.g., pressure sensors, switches, etc.), as will be understood by those skilled in the art.

[0073] Software corresponding to the various features of the present invention discussed above can be encoded and stored on a variety of computer-readable storage media, suitable media including magnetic disks or magnetic tapes, optical storage media such as optical discs (CDs) or DVDs (Digital Versatile Discs), flash memory, and other non-transitory media (e.g., stored in computer 1110). (It is understood that "storage" of data is different from the propagation of data using temporary media such as carrier waves). The computer-readable medium encoded with program code can be packaged together with a compatible electronic device, or the program code can be provided separately from the electronic device (e.g., downloaded via the Internet or as a separately packaged computer-readable storage medium). Those skilled in the art will understand many variations, modifications, and alternative implementations of the system environment incorporating the above-described UX software and operating the various novel input devices described throughout this disclosure.
