Abstract (en)

[origin: WO2022066744A1] A method for testing for visual impairment is provided. The method includes rendering, via a computing device communicatively coupled to a head mounted holographic display device, a virtual target displayed to a user within the holographic display device. The method further includes rendering, via the computing device, at least one virtual light within a field of vision of the user within the holographic display device. The method also includes identifying, via the computing device, whether input was received from the user, wherein the input comprises an indication that the user identified the at least one virtual light. The method further includes generating, via the computing device, a map identifying one or more locations that the user identified the at least one virtual light or did not identify the at least one virtual light.
