註釋Abstract: "Although the popularity of virtual environments is widely known, little is known about the usability of virtual environment displays. This paper presents experimental data on the effect of virtual environment display parameters on task performance. In this investigation, subjects performed an object recognition and 3-dimensional manipulation task in a virtual environment given real-time visual feedback by dynamic display techniques. The subjects controlled a 'virtual crane' by the movements of a SpaceBall [superscript TM] input device. The interaction of stereoscopic depth cues with viewpoint position is evaluated in this experiment
