Though small size touch based displays have recently been very common, there is still much to do to make them affordable for larger sizes. One of the ways for doing so, which has be studied for the last decade, is to use camera based approaches in which one or more cameras are connected to a computer to use the processing power of the computer to provide touch features for a third device. This paper purposes such a system for providing touch features for a normal LCD monitor in which the only available processing power is the one provided by an android smart phone which is connected to the monitor. To recognize the actual touches this paper introduces the speed analysis of the fingertip which has been proven through experimental results to be effective and robust.
