Systems and methods disclosed herein are related to an intelligent UI element selection system using eye-gaze technology. In some example aspects, a UI element selection zone may be determined. The selection zone may be defined as an area surrounding a boundary of the UI element. Gaze input may be received and the gaze input may be compared with the selection zone to determine an intent of the user. The gaze input may comprise one or more gaze locations. Each gaze location may be assigned a value according to its proximity to the UI element and/or its relation to the UI element's selection zone. Each UI element may be assigned a threshold. If the aggregated value of gaze input is equal to or greater than the threshold for the UI element, then the UI element may be selected.

Intelligent user interface element selection using eye-gaze

In aspects of replay of recorded touch input data, a computing device can store recorded touch input data that has been previously recorded based on multiple instances of user inadvertent contact on touch-enabled devices. A replay test application is implemented to test one or more user devices for inadvertent contact rejection using the recorded touch input data, such as to test a palm rejection algorithm of a user device. The replay test application is implemented to communicate the recorded touch input data to a screen overlay device that generates touch inputs on a touchscreen of the user device to test the palm rejection algorithm of the user device. The replay test application also monitors the user device for an action responsive to a touch input that is not filtered as an inadvertent contact with the touchscreen of the user device.

Replay of recorded touch input data

Methods, systems, and computer program products are described herein an extensible input stack for processing input device data received from a plurality of different input devices attached to a computing device. The extensible input stack comprises a plurality of stack layers. Each of the plurality of stack layers performs a particular set of processing with respect to the input device data, among other operations. Each of the plurality of stack layers comprises a code interface, which is used to provide and/or or receive data from the input device and/or other stack layers. Each of the stack layers is extensible to include additional functionality to support new input devices. By separating out the functionality performed by the input stack into separate stack layers, and having each layer accessible via a code interface, the functionality of each of stack layers may be easily extended to support any type of input device.

Extensible input stack for processing input device data

An example method includes receiving a digital certificate corresponding to a user at a stylus device. The method includes transmitting the digital certificate and associated digital ink data to a touch device to authenticate the user based at least on the digital certificate and the associated digital ink data in response to detecting that the stylus device is within a threshold range of the touch device.
