Abstract: A method is disclosed, the method comprising the steps of receiving, at a first time interval from a first sensor configured to output data indicative of a first position of an eye, first data; receiving, at a second time interval from a second sensor configured to output data indicative of a delta position of the eye, second data; determining, based on the first data, a first position of the eye; determining, based on the second data, a delta position of the eye; determining, using the first position of the eye and the delta position of the eye, a second absolute position of the eye; and in response to determining the second position of the eye, generating an output signal indicative of the second position of the eye.

Abstract: A display subsystem for a virtual image generation system comprises a planar waveguide apparatus, an optical fiber, at least one light source configured for emitting light from a distal end of the optical fiber, and a mechanical drive assembly to which the optical fiber is mounted as a fixed-free flexible cantilever. The drive assembly is configured for displacing a distal end of the optical fiber about a fulcrum in accordance with a scan pattern, such that the emitted light diverges from a longitudinal axis coincident with the fulcrum. The display subsystem further comprises an optical modulation apparatus configured for converging the light from the optical fiber towards the longitudinal axis, and an optical waveguide input apparatus configured for directing the light from the optical modulation apparatus down the planar waveguide apparatus, such that the planar waveguide apparatus displays one or more image frames to an end user.
