I'm currently developing a interactive installation in a dome with Kinect and Bitalino. Idea is that visuals+sounds will adapt according to your ECG and body movement. It will be used by one person at a time for about 5 minutes. During a day many people will use it.
Is there an alternative to attaching the electrodes on the body? Because attaching the electrodes to every person will take a lot of time. Is is possible to attach the electrodes to a metal part for instance and let people hold this? Like they do in this movie for instance:
That way we could quickly switch between people. Accuracy is not very important in this installation, as long as I have some kind of heart rate signal.
Any help or advice would be greatly appreciated. I don't know so much about electrodes and how to use them yet. The way I understand it the main purpose of the electrodes is to reduce noise of the incoming signal, right? Just touching a metal wire would generate too much noise?
