This paper is an illustrative approach for developing a visual interface for a gesture recognition system using color based blob detection. The software developed using the prescribed framework serves as a gesture interpretation system and is used to emulate the computer mouse with finger gestures. The objective is to develop an intuitive way to interact with computers and other digital devices and yet make it easy to use and cost effective at the same time. Although vision interfaces for gesture recognition have been researched and developed for some time, this approach has its own uniqueness and is more effective in many circumstances. The prescribed framework minimizes hardware requirements as it only requires a webcam other than the computer itself. The minimization of hardware requirements make it cost effective and easier to obtain. The predefined gestures are simple yet intuitive as these are inspired by certain every day gestures or movements that are used to interact with several tools and equipment in our daily life.
