Xybernaut/Hitachi VII/POMA/WIA computer

Switching to a 32-bit RISC architecture and Windows CE (which was much lighter-weight than Windows and focused on the embedded market) enabled Xybernaut to employ a smaller form factor for its devices. The 640x480 pixel resolution headset weighed 85 g, and the system itself weighed 280 g. The interface still centered around normal windowing metaphors, but the mouse hardware was smaller and more agile, similar to an optical mouse inverted so the user could swipe his finger over it for control.
