On being given the initial idea, we started to find more about the latest inventions going on these fields. After some study we found that all the big universities across the world have a haptics division which are pursuing research in the domain of our present interest including MIT Media Labs, Stanford etc. Further, since the release of XBOX360 Kinect in November last year, almost all these haptic departments have started projects for leveraging Kinect's capability for making various haptic interfaces. Even though the release of Kinect has still not completed one year, vast applications have already been developed centered around it. Even the present study of work given to us belongs to that category. Even various applications are already existing in the labs/markets which make use Kinect for making assistance technological devices for the visually impaired people.
Keeping in mind the above stated facts, we are now fully aware that our task would not be to simply emulate what already has been done at various places but to go few steps further to make an innovative product which helps the society to grow.
