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.
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.
