Abstract
An interactive stereo system was implemented to allow a user to draw and modify B-Spline space curves. A time-multiplexed, liquid crystal shutter system was used to produce true three-dimensional output. A six degree-of-freedom input device was used to drive and control the stereoscopic cursor. Several different cursor types were investigated to determine which were suited to this application. Cursor characteristics were examined to determine their influence on the user''s ability to accurately and proficiently use the system.
