VR Optics

BL: I heard Sega ran aground of some optical issues in their attempt at goggles. it is a frame rate problem, and a convergence problem. I'm impressed with the rapid advances in computing in the past two years, just in the speed of machine required to run 60 field-per-second video, but what causes headaches is a lack of visual convergence in rendering near field objects.

JC: You mean the sick stomach feeling we hear about?

BL: Well, yes -- that is a slightly different issue... but they're related. ... I don't see any big impediments -- we'll see optics continue to improve dramatically and quickly. Our general feeling is the object situation will start improving when we start employing servos or micro-machines to dynamically adjust and compensate for those gnarly little convergence issues.
