Sensors and input devices

Rona Innes demonstrated some interesting sensors and examples of input devices.
The Arduino looks worth further research. Mike blow also mentioned it in his talk earlier.

I was initially put off as it seemed quite complicated, but it's definitely worth another look. I was also interested in the video input Rona demonstrated, particularly using a web cam into flash or director to display graphics, or visual effects on the video.
ghostly mirror was particularly impressive, the effects are quite stunning. This would be worth exploring more, especially if sound input could be added also.
Some of the flash stuff which displays graphics that are triggered by sound via a microphone I've been looking at recently, and did some research with voice activated software and voice recongnition. This gave variable results - the voice recognition stuff needs time to train the software to recognise voice input and not give garbled output. Will spned more time see what interactive art could be triggered by vocal commands and sounds. I've also just sent away for a webcam to have a play over the break.
