Near eye display and related computer-implemented software and firmware
A near-eye display for operation of an augmented or mixed reality system that integrates the virtual image generated by the near eye display to the real environment taking account of the visual processes of the retina, the visual cortex and the oculomotor system. The near eye display is provided in the form of a transparent optical module attached to and aligned with a pair of eyeglasses providing the refractive correction required by the wearer. The effect of the light field created by the eyeglass optic and the transparent optical module are used as inputs to the software or firmware program that drive the micro-display in the transparent optical module and control the location of the content as well as the fixation point being displayed on the micro-display. The near eye display acts as the master and the wearer's or user's eyes as the slave. Thus, the light emitters of the near eye display cause the eye(s) of the user to move and be positioned.
