Three-hundred-sixty-degree audio/visual immersion and the restoration of non-verbal communication cues are essential features for interfaces inviting the human body in cyberspace. The Posture Platform is a network of bases that offers access to a shared virtual environment. Each base is composed of an immersive 360-degree visual display, a surround-sound system, an array of image capture devices, a microphone, an omnidirectional controller/pointer, and a computer with wifi and an internet connection. The Drawing Room is the most recent virtual space developed for the platform. It invites participants to a blank shared space where they draw their own environment collaboratively. The platform, and the project it hosts, is an example of the art, design, and engineering challenges and opportunities associated with development of inhabitable cyberspace.
