Zuckerbergs Meta is working feverishly to get to the Metaverse, the virtual reality world. To this end he is working on the problems of presenting visually a world that is 100% defined by software. According to the roadtovr.com article and as outlined in the video, the four primary problems are:
- Varifocal: the ability to focus on arbitrary depths of the virtual scene, with both essential focus functions of the eyes (vergence and accommodation)
- Distortion: lenses inherently distort the light that passes through them, often creating artifacts like color separation and pupil swim that make the existence of the lens obvious.
- Retina resolution: having enough resolution in the display to meet or exceed the resolving power of the human eye, such that there’s no evidence of underlying pixels
- HDR: also known as high dynamic range, which describes the range of darkness and brightness that we experience in the real world (which almost no display today can properly emulate).
