Reducing Arm Fatigue in Virtual Reality by Introducing 3D-Spatial Offset

Arm fatigue is an important factor affecting user experience in Virtual Reality (VR). In this work, we have proposed ProxyHand and StickHand, virtual hand techniques to address issue. Using or users can flexibly adjust the 3D-spatial offset between physical its representation. This will allow keep their arms a comfortable posture (vertically down) even when they manipulate objects locations that require lifting of using default interaction method. Proposed StickHand similar Underlying concept introduce representation VR. However, respond differently user’s movements because different working mechanisms. Question arises whether negatively impact control ability as directness being violated. To investigate this, conducted studies where were asked perform object translation, rotation hybrid tasks. are used combination some scenarios maximize positive on raises question find best possible these hands reduce arm fatigue. Firstly, for purpose, combined both by manually allowing switch StickHand. Secondly, machine learning automatically hands. Results showed introduction largely reduced while offering equal performance method all tasks; task. Users preferred interact VR environment longer periods time.
