Tracking method for Human Computer Interaction using Wii Remote

Over the years the techniques and methods that have been used to interact with the computers have evolved significantly. From the primitive use of punch cards to the latest touch screen panels we can see the vast improvement in interaction with the system. The same applies to the projection technology for creating various geometric displays. Researchers are exploring new ways of projection and interaction technologies to create `illusion' that can reshape our perception and interaction methodologies. In this paper we implemented (Infrared) IR light source tracking system which can be used for tracking single and multiple IR light source positions and can be used effectively in optical tracking problems such as tracking head position which is all pervasive requirement in a Virtual Reality System. We present a method of mapping IR light source position and orientation to an image. We defined the interaction techniques for an image manipulations with the help of fingers such as zoom, tilt/rotate, scale etc. We can extend our tracking capabilities to implement the touch screen feature to commercial applications. The paper illustrates the hardware and software used for implementing IR light source tracking based applications.
