There have been a few postings lately about peoples' preference for
stereoscopic HMDs. As a follow-up to that discussion, I'd just like to
note that we have found people have much more trouble with simulator
sickness in stereoscopic as opposed to monoscopic HMDs. Using the
Simulator Sickness Questionnaire (SSQ), we found that a stereoscopic
HMD made people significantly more nauseous than the monoscopic HMD.
Although the eye strain and disorientation subscales did not quite
reach statistical significance, if you look at the data, there is a
very obvious trend for the stereoscopic HMD to produce greater eye
strain and disorientation also.

(In case anybody's wondering, we did have an IOD calibration for each
individual, and we did have the software calculate views for each eye,
so no extra lag would occur in the stereo condition.)

unfairness of the universe."
