Gesture Recognition Technology

Gesture recognition technology: A new era of the device control

There are a number of times when the word gesture control is heard these days. Many people wonder about this technology and ask what gesture recognition technology is. It is seen as a medium for computers to understand the body language of human beings. A bridge is created between humans and machines, (in a way like the graphical user interface) that will limit the majority of the inputs to mouse and keyboard. One can use the concept of gesture recognition and point to the computer screen and then the cursor will move accordingly. It can be used as per various combinations with other techniques like image processing and computer vision. In short, it enables human beings to interface with machines and natural interaction is possible, without the aid of any mechanical devices.

Gesture Recognition Technology

Gesture recognition is a mathematical interpretation of human motions, with the aid of a computing device. It is a part of perceptual user interface, and its components are voice recognition, lip or face recognition. Gestures can emerge from any state or body as well as face emotions. But it is observed that they mainly originate from the hands and the face. In present times gesture recognition is mainly centered around the hand and facial movement recognition. In the case of gesture recognition, body gestures are read by a camera, and then the captured data is sent to a computer. This data is later used by the computer to handle devices or applications. In a way, gesture recognition can be termed as gesture control as well.

Gesture Recognition Technology

Through gesture recognition, computers can understand human language in a better way. A better link between humans and machines is established rather than the basic graphical user interface or text user interfaces. All these old-fashioned methods, limit all the inputs to the mouse and the keyboard. With the help of gesture recognition, human-machine interactions, is interpreted with the help of a mechanical device. The benefits offered by this method will make standard devices like keyboard or the mouse a thing of the past.

The prime motive of gesture recognition research is to develop a system, which can identify gestures and use them for control or convey information. To understand what gestures are, one needs to understand the biological and social aspect of it.

Social and biological definition of gestures

When you consider gestures from the social and biological point of view, you will feel that gestures are loosely defined. People use a host of gestures to communicate and it is used for everything like to point the finger at a person or to convey information. From the biological point of view gestures means to embrace all kinds of situations where an individual engages in movements to communicate.

Architecture

·         Basic gesture or input device is the tablet of word processing

·          Two-dimensional hand gestures are sent via this system( an input device is connected to the memory of the computer, and it will appear on the monitor of the screen)

·         Symbolic gestures are then identified as editing commands with the help of geometric modeling techniques.

·         Execution of commands, and modification of documents stored in the memory of the computer.

In the domain of personal computing, gestures are often used for input commands. When you understand gestures as inputs, it allows the computers to be accessible by physically handicapped people. In addition, there are technical glitches relating to the implementation of gesture recognition technology; some social challenges are also presented. Gestures are intuitive, simple and accepted on a universal level.

In the overall context, the gesture recognition tool limits our over-reliance on machines, and a liaison is created between machines and human beings. The advantages of it are immense, and the future looks bright as well.
