Mum opens the fridge, recites her shopping list into a microphone built into her glasses, which then appears as text on the lenses, and is beamed down to the local supermarket to be boxed up and delivered to her home.
This might sound slightly far fetched, but it is one of the visions of the future that came out of the Second International Symposium for Wearable Computers at Carnegie Mellon University, Pittsburgh.
With computer power doubling every 18 months in accordance with Moore?s law, the symposium agreed that it will not be long before computers are small enough to fit into clothes, jewellery and glasses.
One of the most advanced technologies on display was a pair of glasses with a built-in monitor developed by Micro Optical. A very small transluscent display sits in the centre of the lens. Electronic circuits in the side of the frames beam images onto the monitor. Microoptical believes the glasses could be on sale within five years.
The glasses work via a wire connected to the back of the earpiece and directly linked into a laptop. Micro Optical is now working on a battery to make the glasses more portable together with voice recognition so that commands can be recorded directly into a computer.
