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.

Claim (Index 1):
A wearable heads-up display (WHUD), comprising:\n a support frame; a display carried by the support frame; a glint detection module carried by the support frame that, in operation, determines glint space points in a glint space that correspond to a region in a field of view of an eye of a user at which a gaze of the eye is directed; at least one processor carried by the support frame, the at least one processor communicatively coupled to the display and the glint detection module; and at least one nontransitory processor-readable storage medium carried by the support frame, the at least one nontransitory processor-readable storage medium communicatively coupled to the at least one processor, wherein the at least one nontransitory processor-readable storage medium stores data or processor-executable instructions that, when executed by the at least one processor, cause the at least one processor to:\n receive a glint space point in a glint space captured by the glint detection module, the glint space point representative of a position of an eye of a user of the WHUD; \n from time-to-time during regular operation of the WHUD by the user,\n determine a gaze location in a display space of the display based on the received glint space point and one or more calibration point models, each of the one or more calibration point models comprising a plurality of calibration points, each calibration point comprising:\n a glint space point; and \n a display space point in the display space of the display, the display space point representative of a location on the display of a user interface (UI) element displayed on the display; and \n \n dynamically generating one or more child calibration point models, wherein to dynamically generate one or more child calibration point models, the at least one processor, for each calibration point model:\n generates one or more additional calibration points; and \n adds the one or more additional calibration points to the calibration point model.
