Distant Hand Interaction Framework in Augmented Reality

Recent augmented reality (AR) head-mounted displays support shared experiences among multiple users in real physical spaces. While previous research looked at different embodied methods to enhance interpersonal communication cues, so far, less research looked at distant interaction in AR and, in particular, distant hand communication, which can open up new possibilities for scenarios, such as large-group collaboration. In this demonstration, we present a research framework for distant hand interaction in AR, including mapping techniques and visualizations. Our techniques are inspired by virtual reality (VR) distant hand interactions, but had to be adjusted due to the different context in AR and limited knowledge about the physical environment. We discuss different techniques for hand communication, including deictic pointing at a distance, distant drawing in AR, and distant communication through symbolic hand gestures.
