ARPad: Compound Spatial-Semantic Gesture Interaction in Augmented Reality
Yang Zhou, Jie Liu, Peixin Yang, Xinchi Xu, Bingchan Shao, Guihuan Feng, Bin Luo · 2023
In this paper, we propose the concept of compound spatial-semantic gesture interaction, in which spatial semantics is defined as the combination of world-level spatial semantics and object-level spatial semantics. The semantics of compound spatial-semantic gesture is determined by both the gesture and the spatial location of the gesture, which can increase the interaction bandwidth of gestures and improve the user experience. We present three typical compound spatial-semantic gesture application scenarios. Finally, compound spatial-semantic concepts can be applied to other interaction channels, which provides a feasible and general implementation method for expanding the interaction in Augmented Reality (AR) scenarios.
