Gesture recognition is the first step to fully 3D interaction with computing devices. The authors outline the challenges and techniques to overcome them in embedded systems.
As touchscreen technologies become more pervasive, users are becoming more expert at interacting with machines. Gesture recognition takes human interaction with machines even further. It’s long been researched with 2D vision, but the advent of 3D sensor technology means gesture recognition will be used more widely and in more diverse applications. Soon a person sitting on the couch will be able to control the lights and TV with a wave of the hand, and a car will automatically detect if a pedestrian is close by. Development of 3D gesture recognition is not without its difficulties, however.
