Gesture Recognition is a technology which is used to identify human gestures with the help of mathematical algorithms. Gesture recognition recognizes the hand, tracks the hand movements & also provides information about hand position orientation and flux of the fingers. The colour markers are placed at the tip of the user fingers. This helps the webcam to identify the movement of hand and the gesture recognition. The drawing application allows the user you to draw on any surface by tracking the fingertip movements of the user’s index finger. The pictures that are drawn by the user can be stored and replaced on any other surface. The user can also shuffle through various pictures and drawing by using the hand gesture movements.


  • Sensor based digital pen 


  • Some board is required for writing


  • Gesture based digital pen


  • It is a method of training hands to quickly sketch what the brain has already seen.


Digital Art Drawing In The Air Through Camera


Video is captured with the use of camera and it is converted to frames, by applying the HSV to the frames and the red threshold is applied to the video converted the use of red threshold centroid value can be estimated. Now we can draw the line using this centroid value with its exponential values.


  • Raspberry Pi
  • SD card
  • Monitor


  • Raspbian
  • Python
  • OpenCV


By this we can achieve the pen, paper less drawing, and we can make physically challenged people to draw with their gestures
