Abstract

We can control power point show or media player through the swipe. Just swipe over the sensor to control it, the circuit has 2 sets of sensors for sensing the swipe. The sensors has an IR led with a photo diode. For media player show your hand over the sensor to play/pause the song. To stop the song show the hand over the sensor 1,to play the next song just swipe the hand from right to left and to play previous song swipe the hand from right to left. The same swipe motion is used for power point control. The microcontroller code is written in assembly language and pc application is written in visual basic 6.
