Physically Realistic Interface for a user inside VR

Interaction between a user inside a virtual space and virtual objects is described. Incorporating a user's live image into a virtual space enables him/her to exist in the same place as objects and to interact with them. There are, however, the lack of guideline to design interaction style makes users confused about how to use it. This article proposes a common implementation framework that forces the interaction to be physically realistic. As a result, the look & feel of interaction becomes uniform. In a ball game application and virtual electronic controllers made by this framework, a user manipulated/played in the same way as those in the real world. This framework could provide novice-friendly or hands-free interface ubiquitous around public or daily places.
