What is Gesture Interaction?
Gesture recognition is a topic of computer science and language technology with the aim of interpreting human gestures through mathematical algorithms. It is a subdiscipline of computer vision.
Gestures can originate from any movement or bodily state, but they usually originate from the face or hand.
Current focuses in the area include the recognition of emotions from face recognition and hand gestures. Users can use simple gestures to control or interact with devices without physically touching them.
Many approaches have been made using cameras and computer vision algorithms to interpret sign language. However, the identification and recognition of posture, gait, proxemia and human behaviour are also the object of gesture recognition techniques.
Gesture recognition can be seen as a way for computers to start understanding human body language, thus building a richer bridge between machines and humans than primitive text user interfaces or even GUIs (graphical user interfaces) , which still limit most keyboard and mouse inputs and interact naturally without any mechanical devices.
Using the concept of gesture recognition, it is possible to point a finger at this point it will move accordingly. This can make conventional entry redundant and even redundant devices.
