Microsoft has announced the new Natal motion controller fro the XBox 360 at this years E3 conference. Natal is a small, device that sits underneath the screen and senors the users movement, completely eliminating the need for a controller.
This offers huge potential in the world of GIS/Urban visualisation, both in the professional realm and for communicating geography and architecture to a wider audience. Imagine a musuem based installation written for the XBox via the XDA displaying geospatial information that accepts both voice and movement commands.
Game engines and gaming devices offer a lot of potential for visualisation and simulation and with Natal that has just got more interesting.
