Gesture Recognition System
The ability of a computer to scan, store, and recognize human gestures as the mode of interaction with machines.
What is Gesture????A gesture is a form of non-verbal communication in which visible bodily actions communicate particular messages, either in place of speech or together and in parallel with words. Gestures include movement of the hands, face, or other parts of the body.

In order to detect hand gesture, data about hand will have to be collected.A decision has to be made as to the nature and source of the data. Two possible technologies to provide this information are:1)A glove with sensor attached that measure the position of finger joints.2)An optical method (Hand)
Data GloveKEYS:a)Accelerometers b)Data Board c)Glove d)Arm Tracker

Face Recognition SystemTask of identify an already detected face as a known or unknown face. In more advance case “Telling exactly who’s face it is?”Difference between Detection and Recognition?Detection RecognitionIdentify an object as a face andDecide if this face islocate it in input image some one known or unknown

Iris RecognitionIris recognition is an automated method of biometric identification that uses mathematical pattern-recognition techniques on video images of the irises of an individual's eyes, whose complex random patterns are unique and can be seen from some distance.
Distinguish between fake and natural Iris ?
Why we introduce Iris Recognition System?
Advantages of Gesture Recognition System
1. Sign language recognition2. Directional indication through
pointing. 3. Control through facial gestures4. Immersive game technology5. Affective computing. 6. Remote control. 7. Alternative computer interfaces
Drawbacks of gesture Recognition System
• The cost of implementation• Such systems are difficult to develop as each
gesture is assigned a specific control command, this system is not platform independent since certain control commands vary as the operating system varies.
Future Scope
• Control of consumer electronics • Computer games • Security System• Television • In ATM’s
