Using Feedforward to Reveal Interaction Possibilities in Virtual Reality

In virtual reality (VR), interactions may fail when users encounter new, unknown, or unexpected objects. We propose using feedforward in VR to help interact with objects by revealing how such work. Feedforward lets know what do and it showing the available actions outcomes before an interaction. this paper, we first chart design space of illustrate for specific interactions. discuss starting feedforward, previewing outcomes, returning world its state feedforward. Second, implement three real-world applications show can be applied multistep interactions, perceived interactivity, discoverability. Third, conduct evaluation 14 experts understand usefulness. Finally, summarize findings our work on 15 guidelines.
