The current AVESS has targeted to creating fundamental virtual world using tools of Second Life and its user interface is limited to 2D input devices. A wide spectrum of interaction will be needed to enhance this AVESS system to further improve the user"s virtual presence with non-verbal interface such as haptic, visual, kinematic and emotional interaction. Hstar proposes a robotic avatar interactive console (RAIC) system for enhancing AVESS user interface capacity. The proposed RAIC will be archived by integrating robotic haptic interaction devices, visual capture and 3D head-mount display in virtual environment, and kinematic motion and posture capture via wearable sensing devices. This system will: 1) provides 3D amputee-avatar haptic interface, 2) supports 3D immersive visual capture and display in AVESS environment, 3) provides remote patient monitoring and physical accessibility to therapist, 4) provides a remote platform for necessary at-home therapy procedures, and 5) supports kinematic capture of patient motion and body postures and representing on avatar model. Our primary innovation is a 3D robotic avatar interactive interface console for the AVESS that provides safe haptic, visual, and therapeutic interaction via the creative virtual world for the combat injured amputee patients.
