Abstract:
Eye tracking systems and methods include such exemplary features as a display device, at least one image capture device and a processing device. The display device displays a user interface including one or more interface elements to a user. The at least one image capture device detects a user's gaze location relative to the display device. The processing device electronically analyzes the location of user elements within the user interface relative to the user's gaze location and dynamically determine whether to initiate the display of a zoom window. The dynamic determination of whether to initiate display of the zoom window may further include analysis of the number, size and density of user elements within the user interface relative to the user's gaze location, the application type associated with the user interface or at the user's gaze location, and/or the structure of eye movements relative to the user interface.
