  • Patent number: 11175735
    Abstract: Systems and techniques are disclosed that provide application analytics data that combines gaze data and selection data. An application is configured with UI items that are grouped for analytics tracking and configured to track gazes and selections. When the application is used, the user's eye movements and pauses are monitored to identify when the user gazes upon a UI item. In one embodiment, based on determining that a gaze location is within a bounding box corresponding to a first UI item, the system determines that the gaze corresponded to the first UI item. The system also identifies subsequent selections of other UI items in the group. After a selection of a second UI item in the group is received, application analytics data is provided that identifies the gaze corresponding to the first UI item occurring prior to the selection of the second UI item.
