I need ppt on touchless touch screen technology

Abstract
It's up to you to fiddle with touch screen and touch screen to end up scratching when the initially great furore. Gone are the days was created. Touch screen displays to invest such a finger touchscreen can result in gradual de-sensitization as ubiquitous a pointing device with a touchscreen display touch worldwide. Are Frequent and eventually could lead to failure of the touchscreen.

This Touchless control of electrically operated equipment a simple user interface to avoid being developed. EllipticLabs innovative technology you touch them without computers, MP3 players or mobile phones lets you control your gadgets. Touchless control for electrically operated device provides a simple user interface. Choose the sensor or sensor other systems this system a certain hand or finger and motions, a wave of the hand, or a flick of the hand in an area, or an area holding or pointing hand is dependent on the distance depending on the contrast for example with a finger.

Device hand motion detection with a lens for a solid-state optical sensor based on optical pattern recognition using matrix. This sensor is a digital image processor, which interprets the pattern and speed outputs as a result signals fixtures, equipment, machinery, or any run through electrical signals from the controlling device.
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 ”.
TOUCH LESS MONITOR:
Sure, everybody is doing touchscreen interfaces these days, but this is the first time I’ve seen a monitor that can respond to gestures without actually having to touch the screen.

The monitor, based on technology from TouchKo was recently demonstrated by White Electronic Designs and Tactyl Services at the CeBIT show. Designed for applications where touch may be difficult, such as for doctors who might be wearing surgical gloves, the display features capacitive sensors that can read movements from up to 15cm away from the screen. Software can then translate gestures into screen commands.
WORKING:
The system is capable of detecting movements in 3-dimensions without ever having to put your fingers on the screen. Their patented touchless 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. What is to stop unintentional gestures being used as input is not entirely clear, but it looks promising nonetheless. The best part? Elliptic Labs says their technology will be easily small enough to be implemented into cell phones and the like.
Touch-less SDK:
The Touchless SDK is an open source SDK for .NET applications. It enables developers to create multi-touch based applications using a webcam for input. Color based markers defined by the user are tracked and their information is published through events to clients of the SDK. In a nutshell, the Touchless SDK enables touch without touching. Well, Microsoft Office Labs has just released “Touchless,” a webcam-driven multi-touch interface SDK that enables “touch without touching.”
Using the SDK lets developers offer users “a new and cheap way of experiencing multi-touch capabilities, without the need of expensive hardware or software.
Touch-less demo:
The Touch less Demo is an open source application that anyone with a webcam can use to experience multi-touch, no geekiness required. The demo was created using the Touch less SDK and Windows Forms with C#. There are 4 fun demos: Snake - where you control a snake with a marker, Defender - up to 4 player version of a pong-like game, Map - where you can rotate, zoom, and move a map using 2 markers, and Draw the marker is used to guess what…. draw!

What’s next??
Many personal computers will likely have similar screens in the near future. But touch interfaces are nothing new -- witness ATM machines. How about getting completely out of touch? A startup called LM3Labs says it's working with major computer makers in Japan, Taiwan and the US to incorporate touch less navigation into their laptops, Called Airstrike; the system uses tiny charge-coupled device (CCD) cameras integrated into each side of the keyboard to detect user movements.
You can drag windows around or close them, for instance, by pointing and gesturing in midair above the keyboard.You should be able to buy an Airstrike-equipped laptop next year, with high-end stand-alone keyboards to follow.

Any such system is unlikely to replace typing and mousing. But that's not the point. Airstrike aims to give you an occasional quick break from those activities.

CONCLUSION:
Today’s thoughts are again around user interface. Efforts are being put to better the technology day-in and day-out. The Touchless touch screen user interface can be used effectively in computers, cell phones, webcams and laptops. May be few years down the line, our body can be transformed into a virtual mouse, virtual keyboard and what not??, Our body may be turned in to an input device.

Currently, virtual touch screens (VTS) are used primarily for entertainment and research purposes. A popular virtual touch screen system is the Kinect system made commercially available by Microsoft. The Kinect system is primarily used for consumer entertainment such as playing games and using the menus found on the Xbox system.However, in recent years the Kinect has been used for research projects in the field of robotics and 3-D interactions outside of the field of games such as browsing the web, and medical practices.

There is a potential for the technology where the 3D visualization and physical interaction with the objects is necessary, such as teaching students introductory calculus.

Virtual touch screen technology can also be applied to turn non-touch displays into interactive, touch-capable surfaces using a Kinect sensor in combination with a projector. This type of application allows virtual touch technology to enhance personal display usage as well as better communication and presentation of data to be used in education or business settings.


The Kinect sensor, commonly used in many virtual touch screen applications
In medical practices, virtual touch interaction has been applied to allow users to view and manipulate digital data such as 3D images used in medical scans, allowing medical staff to interact with the data without any physical contact, thus avoiding the need for re-sterilization.[15] Additionally, Microsoft's Kinect sensor has also employed the use of virtual touch screen technology to help stroke patients recover and improve motor function in their limbs through a game-like system involving interpretation of gestures combined with adjustable difficulty levels based on the user's performance.
