Programming with the Kinect™ for Windows® Software Development Kit

Chapter 7. Templated gestures and postures

In Chapter 6 you learned how to use algorithms to detect gestures and postures with the Kinect sensor. The main drawback of the algorithmic technique is that all gestures are not easily describable with constraints. In this chapter, you will learn a different approach, one that uses templates (previously recorded drawings) to identify postures and gestures.

Pattern matching gestures

In the real world, using algorithms to describe gestures can have limitations. For example, if you wanted to detect a circle gesture, you could spend days trying unsuccessfully trying to create an efficient algorithm that would incorporate all the constraints you would have to check for a circular movement. Sometimes a completely ...
