From: frerichs@ux1.cso.uiuc.edu (David J Frerichs) Subject: optical gyros Date: 26 Nov 90 22:37:42 GMT Organization: University of Illinois at Urbana does anyone know of a supplier of optical gyroscopes...??? -or- any sort of lightweight gyro...??? I think the net has finnaly stumbled onto the solution of the simple detection of lateral movements (turning the head)... The accelerometer idea is a bit flaky though... who wants to whip their head around just to get the movement to register... for vertical and twisting motion, I think mercury switches is still the best idea... -dfRERICHS Univ of IL/CU Dept of CompEng
