a concept whereby any normal surface with no internal circuitry and hardware for touch sensitivity, is converted into a touch sensitive surface by using image processing techniques. Using such a technique the paper presents the transformation of a plain white wall into a large touch wall. The virtual touch wall aims at building a gesture sensitive environment for users, to provide them new ways of interaction in their work atmosphere and in their recreational space. The hardware requirements of the system are kept on the minimum , limiting only to a simple USB webcam and a PC .Other alternatives to the PC have also been presented , such as the Beagle Board , which is a mini version of a PC and very inexpensive .The approach is based on simple and fast motion detection trying to eliminate unnecessary regions of interest and a recognition algorithm based on the hand contours , their convexities and a further comparison of hand shapes based on HU moment matching which works on image contours .The paper also presents a way of improving the distorted hand contours by distinguishing between external contours and holes and explicitly filling up holes .The use of a predefined set of contours for each gesture helps in better recognition .A simple state machine is implemented to further improve reliability .A total of 5 gestures have been implemented and tested on the PC and the Beagle Board and the performance compared. The Linux XLIB library and the X display functions have been utilized to control mouse cursor actions and other display properties of the wall. I. INTRODUCTION One of the greatest gifts of almost all living things in this world is the ability to communicate through vocals and actions. Human and machine interaction by far has only been through simple means of communication like a mouse , keyboard or switches .Voice recognition and gesture recognition are two powerful and more natural means of communicating with machines as is with human beings. There are innumerable instances where conventional applications can be replaced with hand gestures[1]-[4]. In many cases special gloves or markers have been used for efficient detection and tracking which constraints the user and other vases demand a very simple and plain background [5]-[7]. In [8] a very real time method of hand gesture recognition based on convexity defects is presented but an analysis based only on convexity defects is dependent …
