 M Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. M Gestures can originate from any bodily motion or state but commonly originate from the face or hand. M In this project we capture gesture from human finger movement and controlled a robot vehicle through that.

 MThe sensor set comprises of an IR LED mounted at the tip of a finger and a IR receiver almost at the junction of the palm and the very finger.

MWhen the fingers are straight, the light from the IR LED is directly incident on the receiver.

MWhen the fingers are bent downwards, the light from the LED goes out and is not incident on the receiver.

When the Tx is forward biased, it begins emitting infra red. Case1: when no IR is incident upon the Rx, Rx would be of the order of mega ohms and hence the output voltage would be higher. Case2: when IR is incident upon the Rx, The resistance of Rx will sharply fall and hence the output voltage would be lower.

 MHere we are using a optical sensor. We used IR pair for this purpose. MThe sensor is giving two outputs-------i. When finger is straight. ii. When finger is bent. 4

 Ease of use Generic robotic systems require years of practice and scientific and technological know-how to operate. Gesture Driven systems are simpler and easier to operate. Any common man with basic knowledge can operate it. This systems tends to penetrate deeper in everyday use rather than being confined in research labs. It will open a new era in Home automation and Remotely operated utility devices at households. Even physically disabled can gain benefit.

  igBee Mobility Ö igBee is a specification for a suite of high level communication protocols using small, low-power digital radios . Ö Wireless modules consume very low power and is best suited for wireless, battery driven devices. Ö IEEE standard 802.15.4.2003 it is an encrypted and secure transmission medium. Ö Recent Development in OpenHAN networking will provide more utility to the end users.

OpenHAN = Open Home Automation Network


  Advanced Robotic Arm M Advanced robotic arms that are designed like the human hand itself can easily controlled using hand gestures only. M The ARM controller will wear the sensor gloves and the robotic arm will MIMIC the movement of the controller. M Advanced robotic arms like these can perform complex and hazardous tasks with ease.

M Proposed utility in fields of Construction, Hazardous waste disposal, Medical science.

  
 Virtual Reality(VR) Combination of Heads Up display, Wired Gloves, Haptic-tactile sensors, Omni directional Tread mills may produce a feel of physical places during simulated environments.
