We've taken a deep interest into 'Ubiquitous Computing' lately. For those not familiar with the term, ubiquitous computing is a form of pervasive and integrated information systems, where the traditional interface between a user and their PC is radically different.
The idea behind it is to create an information aware environment, without having to sit at a computer terminal. Imagine standing at a bus stop, and accessing a timetable which is displayed on the lens of your glasses. We feel we are slowly getting closer to this form of computing. Geeks and gadgets seem to be riding this wave, employing technology such as RFID and 802.11G gizmos, but hopefully the idea will become more refined with time. Think of the Oakley Thump, but on steroids, with voice activation and other goodies. The possibilities are huge.
