Basic gesture recognition
The fundamental approach of gesture recognition is to play around with the skeleton's joint points and apply basic logic to perform some action. Basic gesture detection depends on some pre-defined set of conditions, known as the result set. If the performed action is matched with the result set, we can say that the user has performed a certain gesture, otherwise not.
Note
Implementing the basic gestures is relatively easy and straightforward, however, this approach is the fundamental base of building any kind of gesture-controlled application.
In this section, we will learn a few approaches to recognize the basic gestures and will build an application that leverages the basic gesture recognition approach.
Gesture-detection technique
Gesture detection depends on the tracked joints of the human skeleton because we define the condition of gestures based on the joints. Before jumping into further details, let's have a quick look at the representation of skeleton joints.
