Abstract: Systems, methods and articles that provide dynamic calibration of eye tracking systems for wearable heads-up displays (WHUDs). The eye tracking system may determine a user's gaze location on a display of the WHUD utilizing a calibration point model that includes a plurality of calibration points. During regular use of the WHUD by the user, the calibration point model may be dynamically updated based on the user's interaction with user interface (UI) elements presented on the display. The UI elements may be specifically designed (e.g., shaped, positioned, displaced) to provide in-use and on-going dynamic calibration of the eye tracking system, which in at least some implementations may be unnoticeable to the user.

Abstract: Systems, devices, and methods that use elements of a scanning laser projector (“SLP”) to determine the gaze direction of a user of a wearable heads-up display (“WHUD”) are described. An infrared laser diode is added to an RGB SLP and an infrared photodetector is aligned to detect reflections of the infrared light from the eye. A scan mirror in the SLP sweeps through a range of orientations and the intensities of reflections of the infrared light are monitored by a processor to determine when a spectral reflection or “glint” is produced. The processor determines the orientation of the scan mirror that produced the glint and maps the scan mirror orientation to a region in the field of view of the eye of the user, such as a region in visible display content projected by the WHUD, to determine the gaze direction of the user.
