Method and system for visual depth calibration for head wearable display

Abstract

The present disclosure relates to a visual depth calibration system for accurately rendering visual depth perception of a virtual image in head wearable display, comprising a first distance measurement unit for determining a first distance between a first real object and a viewer, and a second distance between a second real object and the viewer; a first light direction modifier and a second light direction modifier for respectively and changing a direction of a first collimated light signal and a second collimated light signal emitted by a first emitter and a second emitter such that the first collimated light signal and the second collimated light signal are respectively emitted toward a first eye and a second eye with a first angle and a second angle that are altering relative a frontal plane of the viewer to render a binocular virtual image having variable depth perception for the viewer.
