HEAD MOUNTED DISPLAY WITH WAVE FRONT MODULATOR

摘要

An augmented reality device for inserting virtual imagery into a user's view of their physical environment, the device comprising: a display device through which the user can view the physical environment; an optical sensing device for sensing at least one surface in the physical environment; and, a controller for projecting the virtual imagery via the display device; wherein during use, the controller uses wave front modulation to match the curvature of the wave fronts of light reflected from the display device to the user's eyes with the curvature of the wave fronts of light that would be transmitted through the device display if the virtual imagery were situated at a predetermined position relative to the surface, such that the user sees the virtual imagery at the predetermined position regardless of changes in position of the user's eyes with respect to the see-through display.
