Detect movements of a person? I'm working on a Virtual Reality game. I want to detect the position or movement of most of the bones in the human body(e.g. Knees, elbows, shoulders, hands and legs). This person may wear special equipment. How should I detect this?? I also want to get the distances between a certain position(e.g. The Arduino board) and each bone. Any ideas?
What you're looking for is called motion capture. If you google it, you'll find a Wikipedia article that can give you a starting point for deciding which of the many available techniques will suit your project. Youtube also has several videos explaining motion capture, and different technologies.
