Gesture Based Computing

Gesture based computing uses gestures as a form of human-computer interaction. It can be used to replace mice and keyboards by allowing users to navigate interfaces and interact with 3D environments through gestures detected by cameras. Common technologies for gesture recognition include depth cameras, controllers, and single visible light cameras. Gestures can be used for applications in entertainment, gaming, communications for disabled individuals, and as an alternative computer interface.

- 2. A movement of a limb or the body as an expression Of thought or feeling. --Oxford Concise Dictionary 1995
- 3. Offline gestures: Those gestures that are processed after the user interaction with the object. An example is the gesture to activate a menu. Online gestures: Direct manipulation gestures. They are used to scale or rotate a tangible object.
- 4. Interaction with computers are not comfortable experience. Computers should communicate with people with body language. Hand gesture recognition becomes important Interactive human-machine interface and virtual environment
- 5. Replace mouse and keyboard Pointing gestures Navigate in a virtual environment Interact with a 3D world No physical contact with computer Communicate at a distance

- 11. Depth-aware cameras. Using specialized cameras such as time-of-flight cameras, one can generate a depth map of what is being seen through the camera at a short range, and use this data to approximate a 3d representation of what is being seen. Controller-based gestures. These controllers act as an extension of the body so that when gestures are performed, some of their motion can be conveniently captured by software. Single camera. A normal camera
- 12. Two common technologies for hand gesture recognition are: glove-based method Using special glove-based device to extract hand posture Annoying vision-based method 3D hand/arm modeling Appearance modeling
- 13. Data gloves provide very accurate measurements of hand-shape But are cumbersome to wear Expensive Connected by wires- restricts freedom of movement
- 15. Requirements: 2D Gesture Recognition System: • A simple webcam capable of acquiring RGB images 3D Gesture Recognition System: • Two simple webcams capable of acquiring RGB images • A mainboard capable of handling two webcams No special equipment required

- 26. Gesture Based Recognition uses sensing technology to identify a user's actions and to extract key information. This information is then analyzed to determine the user's physical, emotional, or informational state, which in turn can be used to help make the user more productive by performing expected actions or by providing expected information. For example, a Blue Eyes-enabled television could become active when the user makes eye contact, at which point the user could then tell the television to "turn on".
