What is the principle of gesture recognition?

[gguo5]

How does gesture recognition in Intel, such as stone, scissors, cloth, etc., come from?

[MartyG]

In the old series of RealSense cameras that supported hand joint tracking (F200, SR300), they could refer to a map of the joint points and work out what gesture is being made using that reference. This map was stored in the hand tracking module file, I believe. It is explained in the document linked to below, along with a map diagram of the hand joints.
