Future Technology That Will Change the World...
Gesture-Based Computing
Whenever a movie or television show has wanted to depict something futuristic then chances are they've used the notion of gesture-based technology in one form or another. The kinds of computers that are projected into the middle of a room and manipulated by the user in a manner of a conductor directing an orchestra or technology that's linked to eye movements adjusting to the way that the human body works. This has long been the film making world's idea of the future. However as you're probably aware. This technology actually already exists. If you have a smartphone then you're already using it likewise with gaming consoles stuff like shaking a phone to activate certain functions or playing games on Xbox that uses cameras and sensor to enhance gameplay by tracking movement and gestures.
The other major industry where gesture based technology is a playing a growing role is in automotive. So far these things have been mostly confined to temperature controls or things like music volume and such but the use of gesture for the actual driving process is right around the corner. The idea of incorporating human gestures into the technology we use is the natural progression that many of our devices and gadgets have long sought. It's how we imagine the future a place where technology helps improve human lives and is seamlessly incorporated into our homes and workplaces becoming a kind of extension of ourselves well. When you witness just how attached some people are to their smartphones it's simple enough to believe that we've already begun the assimilation.
Gesture Types
- Offline Gesture: Those gesture that are processed after the user interaction with the object. An example is gesture to activate menu.
- Online Gesture: Direct manipulation gestures. They are used to scale or rotate a tangible Objects.
Gesture Recognition: Gesture recognition is a topic in computer science and language technology with the goal of interpreting human gestures via mathematical algorithms. It is a subdiscipline of computer vision. Gestures can originate from any bodily motion or state, but commonly originate from the face or hand. Current focuses in the field include emotion recognition from face and hand gesture recognition. Users can use simple gestures to control or interact with devices without physically touching them. Many approaches have been made using cameras and computer vision algorithms to interpret sign language. However, the identification and recognition of posture, gait, proxemics, and human behaviours is also the subject of gesture recognition techniques.

Human Computing Interface using computing :
- Replace mouse and Keyboard
- Pointing gesture
- Navigate in virtual environment
- Interact with a 3D World
- No Physical contact with computer
- Communicate at a distance
Technologies : Two common technology 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
- Data gloves provide very accurate measurements of hand - shape
- But are cumbersome
- Expensive
- Connected by wires - restricts freedom of movement
Uses of gesture computing :
- Sign language recognition
- For socially assistive robotics
- Directional indication through pointing
- Control through facial gesture
- Alternative computer interface
- Remote control computing
