Abstract

We describe a framework for measuring TRE at the tip of an optically tracked pointing stylus. Our approach relied on a robotic manipulator equipped with a spherical wrist to collect large amounts of tracking data from well defined paths. Fitting the tracking data to planes, circles, and spheres allowed us to derive estimates of FLE and precisely localize target locations. A preliminary analysis of our data suggested that there was bias in the registered pointer tip location that depended on the tilt angle of the coordinate reference frame with respect to the tracking system.
