Pros

The privacy awareness in the device seems very well thought out. Things that might be of a more sensitive nature are positioned closer to the chest.

The idea of incorporating the physical world as a medium for interacting with the virtual world is a very clever way of interacting with a computer.

The device takes advantage of proprioception allowing a user to 'blindly' call up tools they need. Since the tools can be called up for reference at any time, but are not always there, this helps to simplify the display without hindering usability.

Comparison of the full-body interface and the WIMP interface is an important distinction

Using body language cues to determine how people are interacting with the device and each other is an extremely clever idea.
