Gesture recognition
This is a field which interpreting human gestures via mathematical algorithms. Gestures can originate from any bodily motion or state but commonly originate from the face or hand. The current areas of focus in this field are emotion recognition from the face and hand gesture recognition. This technology allows the human beings to interface with the machine (HMI) and interact naturally without any mechanical devices. Controlling a cursor using the gesture could be an example which can displace the devices like the mouse, keyboards and even touch-screens .
Uses of Gesture recognition
-For socially assistive robotics: By reading the accelerometers and gyros sensors in the patient's body the robots can assist in patient rehabilitation in cases such as stroke.
-Sign language recognition.:
esture recognition software can transcribe the symbols represented through sign language into letters of text.
-Control through facial gestures.:computer can be controlled through facial gestures. Eye tracking in particular may be of use for controlling cursor motion
-Directional indication through pointing:has application sin the field of robotics.
-Immersive game technology
-Virtual controllers etc:
Input devices
Depth-aware cameras.: a depth map of the image , then a 3d representation can be helpful in gesture recoggnition in short range
Controller-based gestures: motion can becaptured by software
Challenges
image noise., quality of the equipment used are the major challenges.
