Gesture recognition

Benefits & Drawbacks
2.

Gesture recognition is the mathematical interpretation of a human motion by a computing device.

Gesture recognition, along with facial recognition, voice recognition, eye tracking and lip movement recognition are components of what developers refer to as a perceptual user interface.

Benefits

of gesture recognition
4.

Untitled Slide

  • Replace mouse and keyboard
  • Pointing gestures
  • Navigate in a virtual environment
  • Pick up and manipulate virtual objects
  • Interact with the 3D world
  • No physical contact with computer
  • Communicate at a distance
5.

Drawbacks

of the Gesture Recognition
6.

Untitled Slide

  • Irrelevant object might overlap with the hand. Wrong object extraction appearred if the objects larger than the hand.
  • Performance recognition algorithm decreases when the distance is greater than 1.5 m between the user and the camera.
  • Ambient light effects the color detection threshold

Conclusion

of the desture recognition 
8.

The importance of gesture recognition lies in building efficient human machine interaction.Its applications range from sign language recognition through medical rehabilitation to virtual reality.
