I have been looking into ways I can interact with an audience and feel that motion detection would be a good way to do this, I am looking into making a controversial piece looking into the future of earths climate, with the audience able to make decisions as a world leader. The application will begin when someone moves in front of a webcam, and turn off a few seconds after someone moves away.
If I had more time I could link multiple installation so people can "vote" for different decisions similar to a democratic vote.

Motion Capture

Interactive light installation from The Latest Artists on Vimeo.

This is a video of an installation controlled by the movement of people in the gallery it inhabits: motion sensors use the number and frequency of people in various parts of the space to control the colour and speed of the installation.




SpyToy uses onscreen motion detection, I want to so something very similar with specific areas onscreen that the user must "touch". I am going to try and find a similar code to this.

Another method for using motion capture would be for characters to appear onscreen for every person in the room, and leave at the same time as the person. This could be linked to RSS feeds from the BBC News website and the characters represent whatever is in the news at the time, to do this I would have the program recognize keywords such as 'war, Iraq, Afghanistan, solider' which would bring up a solider character or 'global warming, green, co2, carbon' to bring up a hippie character!
