PATENT Docket No.: SNY-220-WOSYSTEMS AND METHODS FOR PROVIDING ADAPTIVE TREMOR-RESPONSIVE USER INTERFACESCross-Reference to Related Applications

[0001] This international application claims the benefit of U.S. Provisional Patent Application No. 63 / 777,999, filed March 26, 2025, the disclosure of which is incorporated herein by reference in its entirety.Field of the Disclosure

[0002] The present disclosure relates generally to adaptive tremor-responsive user interfaces, and more specifically to systems and methods for providing adaptive tremor-responsive user interfaces.Background

[0003] Tens of millions of people worldwide are affected by neurological conditions such as Parkinson’s disease, Huntington’s disease, and Essential tremor. These disorders impair motor function, presenting significant challenges in daily life. One of the most notable difficulties is operating personal electronic devices like mobile phones, computers, and tablets, because user interfaces for these devices are designed with the assumption of steady hands and fine motor control, making them nearly impossible to use for individuals with movement disorders affecting the hands.

[0004] The challenges are not limited to those with neurological conditions. Even individuals without such disorders can also find it difficult to use personal electronic devices due to unstable environments, such as being on a train or an airplane experiencing turbulence. In these situations, maintaining the accuracy needed for user inputs becomes a significant challenge. This can lead to erroneous inputs and potentially dangerous situations, such as the inability to reliably perform emergency calls or operate critical mobile applications.

[0005] Some adaptive technologies have been deployed to help individuals with movement disorders or those in unstable environments, including voice-activated assistance, and body and eye-tracking solutions, allowing users to control their devices using voice commands, eye movements, and arm gestures, respectively, reducing the need to precise hand movements.

[0006] However, these contactless interfaces alter the user experience of such devices and suffer from certain performance drawbacks. It is desirable to improve the quality of life forPATENT Docket No.: SNY-220-WO individuals with movement disorders by making it easier to interact with touchscreen-based interfaces of personal electronic devices.Summary of the Disclosure

[0039] As mentioned above, the present disclosure sets forth systems and methods for providing adaptive tremor-responsive user interfaces, specifically for electronic devices configured for receiving input via a touch-based user interface. The described systems and methods offer improved user interfaces by enabling adaptive displays tailored to users experiencing neurological tremors or other health or ambient conditions impacting the user’s dexterity. As described, the adaptive, tremor-responsive user interfaces enhance the efficiency of electronic device usage by facilitating faster and more accurate touch-based input while minimizing input errors. Consequently, these adaptive interfaces eliminate the need for users to manually adjust their device settings during episodes of increased unsteadiness, whether due to movement disorders or unstable environments. These and other benefits will be apparent to those of skill in the art.

[0040] Turning to FIGS. 1 A and IB, exemplary systems 100A, 100B for providing an adaptive, tremor-responsive user interface is illustrated in accordance with various aspects of the present disclosure. In various embodiments, the system 100A, 100B include a touch-sensitive input device 102A, 102B, an electronic display device 104A, 104B, and an electronic device 106 in communication with the touch-sensitive input device 102A, 102B and the electronic display device 104A, 104B. In particular embodiments, the touch-sensitive input device 102 A includes the electronic display device 104A, i.e., the touch-sensitive input device 102A and the display device 104A are integrated into a touch-sensitive display. For instance, in the example of FIG. 1A, the touch-sensitive input device 102 A is a touch-sensitive display device comprising a display device 104A that visually presents information to users, a touch-sensitive layer 110 that can sense when and where a touch has occurred on its surface, and, optionally, one or more protective layers 112 that sit over the display device 104 A and touch-sensitive layer 110 to prevent wear and other forms of damage.

[0041] However, it should be appreciated that the electronic display device 104A, 104B need not be physically integrated with the touch-sensitive input device 102A, 102B. That is, in some embodiments, the display device 104B may be a separate wired and / or wireless device that is operatively connected to the touch-sensitive input device 102B via the electronic device 106. For example, as shown in FIG. IB, the display device 104B and the touch-sensitive input device 102B may be separate components of the system 100B that are operatively connected and in communication via the electronic device 106.PATENT Docket No.: SNY-220-WO

[0042] In embodiments, the display device 104A, 104B can employ an LCD (liquid crystal display), an LED (light-emitting diode) display, an OLED (organic light-emitting diode) display, and / or another display technology.

[0043] In embodiments, the touch-sensitive input device 102A, 102B and / or the touch-sensitive layer 110 can be configured to receive touch-based input 114 from a user 116, such as from a user’s finger, or from a stylus manipulated by the user, and / or a similar device. In particular embodiments, the touch-sensitive input device 102A, 102B and / or the touch-sensitive layer 110 utilize resistive touch technology, capacitive touch technology, infrared touch technology, and / or similar technologies. In specific embodiments, the touch-sensitive input device 102A, 102B can be a touchscreen display, a trackpad, and / or a similar device.

[0044] In embodiments, the touch-sensitive input device 102 A, 102B can include a touch device controller 108, as shown in FIGS. 1A and IB. The touch device controller 108 is a specialized component comprising one or more computer processors and one or more types of memory, which is configured to interpret signals from the touch-sensitive input layer 110 and convert them into data that the electronic device 106 can process. In particular embodiments, touch actions (i.e., instances of receiving the touch-based input 114) are measured as signals by the touch-sensitive input layer 110 and touch data are calculated based thereon. The touch data can include touch coordinates that indicates where, relative to a surface of the touch-sensitive input device 102 A, 102B, the user 116 touched. In embodiments, the touch coordinates can be x-y coordinates indicating where the user 116 touched. In further embodiments, the touch data can include temporal information indicating when the user 116 touched the touch-sensitive input device 102A, 102B.

[0045] In still further embodiments, the touch data can include additional forms of data based on the touch input 114. For example, in particular embodiments, the touch-sensitive input device 102A, 102B can be pressure sensitive, and the touch data can include pressure measurements associated with each touch input 114.

[0046] As described herein, the systems 100 A, 100B can include an electronic device 106 that is operatively connected to and / or otherwise in communication with the touch-sensitive input device 102A, 102B such that the touch data can be transmitted to the electronic device 106. This can be achieved through various communication interfaces and protocols, such as I2C, SPI, or USB. As described herein, the electronic device 106 may variously embodied as different mobile electronic devices, including but not limited to, smartphones, tablets, smartwatches, e-readers, handheld gaming consoles, portable media players, and / or the like.

[0047] More specifically, as shown in certain detail in the example of FIG. 1A, the electronic device 106 can include: (i) hardware 118 such as one or more processors, memory, and circuitryPATENT Docket No.: SNY-220-WO (discussed further with reference to FIG. 2); (ii) firmware 120 that directly interfaces with the hardware 118 and controls their functions and operations; (iii) an operating system 122; (iv) a tremor-responsive agent 124; (v) one or more user applications; and / or (vi) one or more graphical user interfaces 128. With reference to FIG. IB, although only the tremor-responsive agent 124 and the user application(s) 126 are illustrated, it should be understood that the electronic device 106 may also include additional components, as shown in FIG. 1 A.

[0048] Each of the one or more user applications 126 can generate a distinctive user interface 128, which may be displayed on the display device 104. The user applications 126 can include, for example and without limitation, one or more social media apps, communication apps, entertainment apps, productivity apps, health and fitness apps, financial services apps, shopping apps, travel and navigation apps, and / or the like, including combinations thereof.

[0049] It should be appreciated that the electronic device 106 can include tens or hundreds of user applications 126, each of which are typically designed and supported by separate software developers. As such, each user application 126 will generate a distinctive user interface 128 that is presented to the user 116 via the display device 104. Each of these user interfaces 128 will typically present a number of selectable objects (buttons, fields, hyperlinks, etc.), but how each user interface 128 presents these selectable objects to the user 116 is varying significantly. Importantly, however, different user interfaces 128 will present selectable objects having different positions, shapes, and sizes, which may not be adapted for users 116 experiencing tremors (e.g., due to a motor function disorder to externally caused instabilities, as described herein). Even if an individual user interface 128 does have some display settings that can be adjusted, these adjustments will not be made across different applications 126.

[0050] Accordingly, the electronic devices 106 of the present disclosure comprise a tremor-responsive agent 124 that is configured to interpret touch-based input data relating to unsteady inputs, determine a shake and / or tremor severity depending on the data, and re-configure the user interface 128 displayed on the display device 104 based thereon. In particular embodiments, the tremor-responsive agent 124 may operate independently of the user applications 126 in order to modify the user interface 128 and interpret touch-based inputs 114, or may communicate with the user applications 126 in order to provide adaptive adjustments (e.g., dynamic scaling, etc.) of the user interface 128. In still further embodiments, the tremor-responsive agent 124 may make adjustments at a system level, e.g., at the operating system 122, which then are communicated to and implemented through the user applications 126.

[0051] As shown in FIG. 1A, the electronic devices 106 of the present disclosure may also comprise a stability sensor 130 that can measure the movement / shaking of the device 106PATENT Docket No.: SNY-220-WO independently of the user input. Thus, the tremor-responsive agent 124 may be able to distinguish between shaking of the device 106 and unsteady touch input from the user 116. In further embodiments, the tremor-responsive agent 124 may make adjustments to the user interface 128 before receiving any user input 114 based on the sensor data from the stability sensor 130. In embodiments, the stability sensor 130 may be an inertia sensor or the like.

In embodiments, these selectable objects can include one or more visual buttons, fields, hyperlinks, and / or the like, including combinations thereof. The user 116 may utilize the touch-sensitive input device 102 A, 102B to provide touch-based input in order to interact with these selectable objects, for example, by scrolling, hovering over, and / or performing a specific gesture like taping, pressing, or swiping, among others. As described herein, each attempt to interact with (e.g., select) one of the one or more selectable objects represents an individual touch action.

[0064] Next, in the step 320, the computer-implemented method 300 can include generating, by a first device controller 108 of the touch-sensitive input device 102A, 102B, positional data corresponding to one or more touch actions. As mentioned above, the first device controller 108 can be configured to interpret signals from the touch-sensitive input device 102A, 102B (e.g., the input layer 110) and convert them into data that the electronic device 106 can process. Thus, when touch actions (i.e., instances of receiving the touch-based input 114) are registered, touch data can be calculated based thereon. In embodiments, the touch data can positional data, including coordinates that indicate where, relative to a surface of the touch-sensitive input device 102 A, 102B, the user 116 touched. In embodiments, the touch coordinates can be x-y coordinates indicating where the user 116 touched. In further embodiments, the touch data can also include temporal information indicating when the user 116 touched the touch-sensitive input device 102A, 102B.

[0065] In embodiments, the positional data can correspond to one or more touch actions registered by the touch-sensitive device 102A, 102B. It should be appreciated that for a user 116 experiencing tremors and / or unsteadiness, the touch action can result in positional data that is not registered as a single point of contact on the touch-sensitive device 102A, 102B. That is, the touch action can result in multiple points of contact over a short period of time, including potentially rapid releases and retrigger events, all of which are associated with the user’s 116 attempt to select a single selectable object of the user interface 128. Thus, the positional data generated by the touch device controller 108 can include a series of coordinates taken over a period of time.

[0066] Then, in the step 330, the computer-implemented method 300 can include receiving, at a processor 202 of an electronic device 106, the positional data generated by the touch device controller 108. As mentioned above, the touch device controller 108 may be operatively connected to and / or in communication with the hardware 118 of the electronic device 106, e.g., the one or more processors 202 of the electronic device 106 via the networking unit 214 and / or the I / O interface 212.PATENT Docket No.: SNY-220-WO

[0067] In the step 340, the computer-implemented method 300 then includes analyzing the positional data received at the electronic device 106 using a tremor-responsive agent 124 to determine one or more tremor severity metrics. In particular embodiments, the tremor severity metrics can be calculated for each touch action. In some embodiments, one or more tremor severity metrics can be calculated by: (i) determining a movement pattern associated with the touch action based on the positional data received, wherein the movement pattern includes a series of coordinates representative of the user’s 116 touch input relative to the touch-sensitive input device 102 A, 102B; (ii) determining one or more amplitudes of the movement pattern; and (iii) determining the tremor severity metrics based on the one or more amplitudes.

[0068] As mentioned above, the movement pattern determined based on the positional data includes at least a series of coordinates representative of the user’s 116 touch input relative to the touch-sensitive input device 102A, 102B. For example, in some embodiments, this may be the movement of the user’s 116 finger. However, in other embodiments, this may be the movement of a stylus or similar device.

[0069] With reference to FIG. 4A, an exemplary movement pattern 408 associated with a touch action is illustrated. As shown, a portion 402 of a user interface (e.g., user interface 128) is provided with a selectable object 404, in this case a circular region of the user interface 128. While the position user’ s finger 406 eventually triggers the selectable obj ect 404 via the touch-sensitive input device 102A, 102B, the user’s finger 406 is tracked over a movement pattern 408 in connection with this particular touch action.

[0070] Based on the positional data, amplitudes of the movement pattern 408 can be determined by calculating the distances between changes in directions of finger movements. In case of steady directional changes with no sharp comer behavior, an ellipse or circle can be calculated, for example, based on the furthest distances of touch points.

[0071] In addition to calculating one or more amplitudes of a movement pattern, one or more offsets can be calculated, i.e., a distance and potentially direction in cylindrical or cartesian coordinates between the center of a selectable object and a center of the finger movement. For example, as shown in FIG. 4B, another portion 410 of a user interface (e.g., user interface 128) is provided with a small selectable object 412 and a larger selectable object 414. In this embodiment, the user’s finger 416 is registered according to the positional data, and an offset between the finger position 416 and the objects 412, 414 can be calculated. As shown, the offset 418 is calculated between the center of the object 412 and the user’s finger 416.

[0072] In particular embodiments, the amplitudes and / or offsets of the movement patterns can be classified or otherwise quantified in order to determine the one or more tremor severity metrics.PATENT Docket No.: SNY-220-WO For example, if the amplitude and / or offset is larger than a threshold, this indicates that the user interface 128 is not suitable for the user 116 given the extent of the unsteadiness. Further, if the amplitude and / or offset is smaller than a threshold, then the user interface 128 may be overcompensating for the user’s 116 unsteadiness and may be adjusted accordingly.

[0073] In embodiments, averages as well as maximum amplitudes and / or offsets can be used to determine the tremor severity, and will also help to sort out un-symptomatic occasional high amplitudes. Averages can also be taken over more than one touch input (e.g., touch action) to avoid unsteadiness due to other factors beyond the user 116.

[0074] After determining one or more tremor severity metrics, the method 300 can include, in the step 350, modifying the user interface 128 displayed on the display device 104 based on these tremor severity metrics. In particular embodiments, the user interface 128 can be modified such that one or more selectable objects appear larger and / or smaller on the display device 104. For example, with reference to FIG. 5, a first user interface 502A is shown having multiple selectable objects 504A of a particular size. In some embodiments, if the tremor severity metrics indicate that the user 116 is having trouble consistently and accurately selecting the objects 504A, then the user interface 502A can be adjusted to be more like the user interface 502B or the user interface 502C, where the selectable objections 504B, 505C have increasing size. Similarly, this can also be done in the opposite direction if, for example, the amplitudes and / or offsets are below a threshold. In embodiments, user preferences can be stored and serve as limits to the scaling in either direction.

[0075] As described herein, one or more steps of the computer-implemented method 300 may be repeated any number of times to dynamically adapt the user interface 128 based on the user’s 116 tremor severity status. Thus, as the user 116 experiences varying levels of unsteadiness, the user interface 128 can be automatically adjusted based thereon.

[0076] In particular embodiments, the positional data and tremor severity metrics may be recorded and sent to a remote server, e.g., for insurance coverage or healthcare provider purposes, to determine systemic or intermittent tremors, and similar purposes. In further embodiments, the tremor-responsive agent 124 may also make recommendations to the user 116 based on the tremor severity metrics, such as when to consult with a healthcare provider in case of increases of amplitude or occurrence.
