摘要
本研究以3D立體空間中進行實驗，探討在3D立體虛擬空間中，移動方向與距離及目標物的寬度對於移動作業績效的關係。因此本研究在虛擬實境中建構一個3D環境，利用Fitts’ law探討10位受測者在該環境下面對不同的顯示方式時績效的影響，以了解在3D虛擬環境下，移動方向和ID以及顯示方式對於移動時間的影響，並使用Simulator Sickness Questionnaire (SSQ)量表來評量受測者的主觀感受。結果發現在3D虛擬環境下，移動方向和ID以及顯示方式對於移動時間有顯著的影響。虛擬的空間進行移動行為時，使用者對於空間深度的判斷會比其他方位來的不易，因此使用者對於視深的績效會較差。未來針對3D顯示系統時進行設計時，應該加強視深顯示部分以避免績效下降。

Abstract
This study evaluates the influences of direction to the target, amplitudes, and target size on movement performance in 3D virtual reality environment. We developed a virtual reality environment. Then, we evaluate the participants’ performance under 3D virtual reality environment and different 3D display by Fitts’ law. And we use Simulator Sickness Questionnaire (SSQ) evaluate the participants’ subjective performance. The results pointed that direction to the target, ID and different display will significantly influent the participants’ movement time in virtual reality environment. When we move in virtual reality environment, it is difficult to judge the space depth. In the future, the design of virtual reality environment should enhance the depth display to avoid lower performance. Results of this study can indicate a referential direction for future Fitts’ law related researches.
