The Effect of Haptic Feedback and Stereo Graphics in a 3D Target Acquisition Task Abstract
Interaction in three dimensional virtual environments is difficult, often resulting in physical or mental fatigue. Haptic interfaces have previously been employed with 2D and 2.5D desktop metaphors in order to improve targeting performance. This paper extends the principle to a 3D environment targeting task. Subjects completed a targeting task with and without haptic feedback, in the form of “virtual magnets” that physically attract the user towards targets in the environment, and with and without the provision of stereo depth cues via a stereo emitter and shutter glasses. It was found that the virtual magnets improved subjects accuracy, but did not improve the time taken to reach the target. Stereo cues improved both the subjects’ spatial accuracy, and significantly improved the temporal measure of performance. |
