ABSTRACT:
It was the touch screens which created a great enthusiasm . Gone are the days when you have to touch the screen and end scratching up. Touch screen displays are very famous world wide . Frequent touching a touch screen display with a pointing device such as a finger can result in a de-sensitization of the touch screen to input and can ultimately lead to the failure of the touch screen. To avoid this problem a simple user Interface for Touchless control of electrically operated equipment is being developed. Unlike other systems which depend on the distance to the sensor depends on hand or finger motions, a hand wave in a certain direction or holding the hand in one area or pointing with one finger.
The device is based on the optical pattern recognition using a solid state optical matrix sensor with a lens to detect hand motions. The 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 through electrical signals.With the touch less touch screen your hand doesn’t have to come in contact with the screen at all. It works by detecting your hand movements in front of it. This is a pretty unique and interesting invention. While using the phone with the finger tip the screen started getting lots of finger prints and scratches. When we use a screen protector, still dirty marks over such beautiful glossy screen is a strict problem. Same thing happens with I-pod touch. Most of the time we have to wipe the screen to get a better unobtrusive view of the screen. Elliptic Labs innovative technology lets you control your gadgets like Computers, MP3 players or mobile phones without touching them. Simply point your finger in the air towards the device and move it accordingly to control the navigation in the device. They term this as “Touchless human/machine user interface for 3D navigation ”.
The system is capable of detecting movements in 3-dimensions without ever having to put your fingers on the screen. Their touch less interface doesn’t require that you wear any special sensors on your hand either. You just point at the screen from as far as 5 feet away and you can manipulate objects in 3D. Sensors are mounted around the screen that is being used, by interacting in the line-of-sight of these sensors the motion is detected and interpreted into on-screen movements. This technology will be easily small enough to be implemented into cell phones.
This unique screen is made by TouchKo, White Electronic Designs and Groupe 3D.The touch sensor is placed over a display screen so that the responsive area of the panel covers the viewable area of the screen. Sensors are mounted around the screen that is being used, by interacting with these sensors the motion is detected and interpreted into on-screen movements. Ellipse Labs says their technology will be easily small enough to be implemented into cell phones and the like ipod.
