Abstract: Systems and methods for performing a device operation in response to a touch input and based on a user's gaze are described. An example device includes a touch sensor configured to sense a touch input from a user, a gaze sensor configured to capture gaze information regarding a user's gaze, one or more processors, and a memory coupled to the one or more processors. The memory stores instructions that, when executed by the one or more processors, cause the device to determine a feature of the user's gaze based on the captured gaze information, and disregard the touch input based on the feature of the user's gaze.

Abstract: A dynamic interface for camera-based authentication. An input device captures an image of a user during an instance of camera-based authentication. The input device selects a positioning template from a plurality of positioning templates based at least in part on a security level associated with the instance of camera-based authentication. The image of the user is displayed, concurrently with the selected positioning template, in a visual interface. The input device captures an authentication image when one or more features of the user relative are aligned with one or more visual cues of the first positioning template.

Abstract: A method for controlling a user interface using an indirect input device includes determining a first touchdown location of an input object, determining a first subsequent location of the input object, calculating a first direction and a first distance between the first touchdown location and the first subsequent location, and moving a cursor representation on a display in a second direction and at a velocity. The method further includes detecting a touchdown event of at least two input objects, determining a second touchdown location of the at least two input objects, determining a second subsequent location of the at least two input objects, calculating a third direction and a second distance from the second touchdown location and the second subsequent location, and modulating a user interface action in a fourth direction at a magnitude.

Abstract: A method and device are provided for measuring force on a force enabled input device having a touch surface. The method includes detecting force information associated with an input object contacting the touch surface, and determining a push event if the force information is either greater than a predetermined static push threshold value, or a substantially monotonic increase of at least a dynamic push threshold value above a low baseline value. The method thereafter determines a release event if the force information either decreases below a predetermined static release threshold value, or decreases from a maximum baseline value by an amount greater than a dynamic release threshold value. The method initiates a first type of user interface action associated with the input object based on a determination of the push event and the release event, wherein the first type of user interface action may comprise determining a virtual button click.

Abstract: Methods and devices are provided that employ multi-function keys to present a preview of potential actions to be taken by user key presses. The input device includes a plurality of key assemblies having a touch sensitive surface. The processing system can sense when one or more respective key assemblies have been contacted or pressed by the object. When the one or more respective key assemblies has been contacted by the object, an indication of a potential action taken in the program is provided to the user. The method determines whether the one or more respective key assemblies have been contacted or pressed by an object. A potential action to be taken is determined and an indication of the potential action is provided.

Abstract: Methods and devices are disclosed for providing additional functionality using multi-function keys. The device includes key assemblies for receiving a contact input or a press input. A processing system is coupled to the key assemblies and configured to determine a number of objects contacting a key assembly. The processing system provides a first response when the key assembly has received the press input from a first number of objects and provides a second response when key assembly has received the press input from a second number of objects. The method includes determining a number of objects contacting a key assembly and whether the key assembly has received a contact input or a press input. A first response is provided when the key assembly has received the press input from a first number of objects and a second function is provided when key assembly has received the press input from a second number of objects.

Abstract: The embodiments described herein provide devices and methods that facilitate improved input device performance. Specifically, the devices and methods provide an input device configured to determine positional and force information for input objects interacting with a sensing region. The system is configured to detect a variable force imparted to an input surface of the sensing region by at least one input object. The variable force dynamically modulates, within a modulation range, a user interface parameter. The dynamic modulation of the interface parameter is modified in response to an additional input object contacting the input surface.
