A head-mounted display testbed device has
been custom-designed by Virtual Research and Virtual Vision to
present a fully adjustable stereo display with variable binocular
overlap, inter pupilary distance adjustment and focus. Software
integration and hardware calibration of this new electronic haploscope
is proceding. The SGI Onyx display computer which will be used
with this system has been upgraded to System 6.2 and the resulting
disturbances to graphics and position sensor timing are being
currently assesed. The previously measured very low system latency
seems achieveable, but the update rate is no longer constant,
threatening to serious degrade the predictive tracking we wish
to introduce.
