Abstract

Hand gesture technology makes users’ lives simpler, achieving “hands free” interaction through eliminating the need to hold or press the device. Since the need of human computer interaction has increased to a great-extent, such a technique needs to be devised that do not depend on Vision or Wearable sensors approach. This paper is a sincere attempt to recognize gestures using EM field detection approach. This requires only an EM field transmitter and a detector (receiver). The novelty of this approach is, it not only reduces extra cost for wearable or vision based sensors but would also account for a wide range of coverage area. In addition to this, method to recognize gestures through EM Waves with the help of a laser light is also practically implemented. The demonstration of this method is illustrated with the help of Macromedia Flash Player. This theory will certainly reduce the cost factor and add to the simplicity of the current human computer interactions.
