It is possible your computer could track your movements around the house by monitoring the electrical noise made by household appliances as you switch them on and off.

"The problem I see with a lot of ubiquitous computing research is that it requires the creation of new infrastructure and technology. A lot of what we have been focusing on is how can you achieve some of these things without requiring Joe Blow to buy new stuff," says Gregory D Abowd, a computer scientist at the Georgia Institute of Technology in Atlanta.

In a paper to be presented at the International Conference on Ubiquitous Computing in Innsbrook, Austria, next week, Abowd and colleagues show that they could train a computer to distinguish between activity in different rooms as their lights were switched on and off, or to tell the signature of microwave oven from that of a ceiling fan.
