Computers have become more visual now a days and further they took up to next step understanding vocal commands and now they have moved to the next step the Touch Screens that is the touch of the skin to the screen. A touch screen is an easy Input device for the users to control software and videos by touching the display screen. A touch system consists of a sensor that receives the touch input. The most commonly used touch technologies are Capacitive and Resistive systems. The touch screens initially created great future. Frequent touching a touch screen display with a pointing device such as a finger can result in the gradual de-sensitization of the touch screen to input and can ultimately lead to failure of the touch screen. Gone are the days why you have to fiddle with the touch screens and scratching up. To avoid this simple user interface, electrically operated equipment is being developed that is control of touch less. Elliptic Labs innovative technology lets you control your gadgets like Computers, MP3 players or mobile phones without touching them. Unlike other systems which depend on distance to the sensor or sensor selection this system depends on hand and or finger motions, a hand wave in a certain direction, or a flick of the hand in one area, or holding the hand in one area or pointing with one finger. The device is based on optical pattern recognition using a solid state optical matrix sensor with a lens to detect hand motions. This sensor is then connected to a digital image processor, which interprets the patterns of motion and outputs the results as signals to control fixtures, appliances, machinery, or any device controllable through electrical signals.
