touch less touch screen sounds
[attachment=21381]
INTRODUCTION
The touch less touch screen sounds like it would be nice and easy, however after closer examination it looks like it could be quite a workout. This unique screen is made by TouchKo , White Electronics Designs , and Groupe 3D. The screen resembles the Nintendo Wii without the Wii Controller. With the touchless 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, until you break out in a sweat. Now this technology doesn’t compare to the hologram-like IO2 Technologies Heliodisplay M3 , but thats for anyone that has $18,100 laying around. You probably wont see this screen in stores any time soon. Everybody loves a touch screen and when you get a gadget with touch screen the experience is really exhilarating. When the I-phone was introduced,everyone felt the same.But gradually,the exhilaration started fading. While using the phone with the finger tip or with the stylus 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 no-no. 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.
Thanks to EllipticLabs innovative technology that 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”.
Current Technoliges:
A touch screen is basically an electronic display of any electronic device which has the ability to identify the pressure and position of a stroke within the energetic area and interconnect with the users command by a nail, stylus or finger.
1 Single touch interaction
2 Multi touch interaction
3 Normal human computer
“Touch Sensor” was primarily designed and developed in 1971 by Dr. Sam. H during his term as an instructor in Kentucky University. Unlike the latest touch screens the elograph was not transparent.Among the technologies of touchscreen there are 3 segments. A thin metallic layer which is resistive and conductive electrically coated over a panel of a resistive screen causes a small variation in the electrical pulses which records the event of touch and transferred to the controller for further processing of the pulses.
Ultra sonic waves are used by the wave technology of surface accousticity passes over to the panel of the touch screen. When the panel is touched, a section of the wave signal is captivated, causing an alteration in the signal. The recorded event of touch is sent across to the controller.
The panel of touch screen with capacitiveness is layered with a substance that stores charges, which when touched; a minute amount of electric charge is derived at contact point. Circuits positioned at every corner of the panel records the charge and transmit the data for further processing to the controller. These touchscreen panels must be used by using the finger only.
Technology Behind It:
It obviously requires a sensor but the sensor is neither hand mounted nor present on the screen. The sensor can be placed either onthe table or near the screen. And the hardware setup is so compact that it can be fitted into a tiny device like a MP3 player or a mobile phone. It recognizes the position of an object from as 5 feet. Here we use electric field sensing and capacitive sensing. Totally here we use 7 sensors.
