Paper Abstract

One of the objectives of this study was to determine which of two cursor control devices would provide the best means of designating targets in stereo three-dimensional (3-D) space. The two devices tested were a joystick and a hand tracker. The second objective was to determine if performance improved with the use of an aiding technique to designate the targets. This aid was incorporated by changing the color of the cursor when it penetrated the target volume. The total 3-D viewing volume was divided into four perceived depth volumes within which the targets could appear. The study showed that the quickest designations occurred when using the hand tracker, and the hand tracker performed significantly better than the joystick when the targets were located in the two volumes behind the screen. There was no difference in accuracy for the two devices. Also, the use of the aiding technique was most effective (target designation time and accuracy) in the farthest behind depth volume and the front-most depth volume. Performance in the other depth volumes showed no advantage of aiding.
