In recent years, several researches are being done to improve the means by which humans interact with machines. Having developed a variety of input devices, we still are not completely comfortable with the present human�machine interaction processes. This stirred up the efforts undertaken to make the machines adapt to the human�s natural means of communication which are speech and body language. The objective of this paper is to implement a real-time vision system which offers better comfort to humans while interacting with machines. In our paper, we showed a simple but efficient method to implement a hand posture recognition system and by means of which we control a bot wirelessly through Bluetooth. The simplicity of our method enables fast recognition of the hand postures shown and therefore achieves the real-time continuous control over the bot.
