Abstract

See full text

Systems and methods for event-based gaze in accordance with embodiments of the invention are illustrated. One embodiment includes an event-based gaze tracking system, including a camera positioned to observe an eye, where the camera is configured to asynchronously sample a plurality of pixels to obtain event data indicating changes in local contrast at each pixel in the plurality of pixels, and a processor communicatively coupled to the camera, and a memory communicatively coupled to processor, where the memory contains a gaze tracking application, where the gaze tracking application directs the processor to, receive the event data from the camera, fit an eye model to the eye using the event data, map eye model parameters from the eye model to a gaze vector, and provide the gaze vector.
