Interactive Screens Using Hand Gestures and Microcontroller

This paper introduces a screen control mechanism for long distance interaction between Human and Computer. This Paper provides solution for controlling the screen elements of different applications and browsers through laser emitting mouse and gesture recognition. The images are being captured from camera mounted on the projector and OpenCV library is used to detect the laser movements. The solution also uses Arduino as the basic processing unit for emulating mouse actions using the buttons. User commands are specified by the laser and thus the actions are initiated with the buttons on microcontroller. When near to screen the hand gesture can be activated using the mouse buttons and thus exhibiting touch screen in a projection. This Hand gesture Recognition is implemented using computer vision library of python, OpenCV, which processes images in real time. According to gesture Recognized, various tasks can be performed like switching between tabs, opening new application, Painting etc.
