Abstract
It was the touch screens that initially created a great furore.Gone are the days when you have to play with the touch screens and the final scratch. Touch screens are ubiquitous all over the world. Touching a touchscreen frequently with a pointing device such as a finger can result in the gradual desensitization of the touch screen to the input and ultimately can lead to a touch screen failure.

To avoid this, a simple user interface for the Touchless control of electrical equipment is being developed. EllipticLabs innovative technology lets you control your gadgets like computers, MP3 players or mobile phones without touching them. A simple user interface for the Touchless control of electrically operated equipment. Unlike other systems that rely on sensor distance or sensor selection, this system depends on hand or finger movements, a manual wave in a particular direction or a hand movement in an area or Hand in an area or pointing with a finger for example.

The device is based on optical pattern recognition using a solid state optical array sensor with a lens to detect hand movements. This sensor is then connected to a digital image processor, which interprets the motion patterns and outputs the results as signals to control apparatus, apparatus, machinery or any device controllable through electrical signals.

INTRODUCTION:
The touch less touch screen sounds like it would be nice and easy, however, after a closer look, it looks like it could be a good workout. This unique display 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 does not have to contact the screen at all, it works by detecting your hand movements in front of it. This is a rather unique and interesting invention, until you get out of sweat. Now this technology does not compare to the hologram-like IO2 Technologies Heliodisplay M3, but that's for anyone who has $ 18,100 out there.

You probably will not see this screen in stores in the short term. Everyone loves a touch screen and when you get a touch screen gadget experience is really exciting. When the phone was introduced, everyone felt the same. But little by little, the euphoria began to fade. While using the phone with the tip of his finger or the stylus, the screen began to have many fingerprints and scratches. When we use a screen saver; The still dirty marks on such a bright glossy screen are a no-no strict. The same goes for I-pod touch.

Most of the time we have to clean the screen for a better view of the screen. Thanks to the innovative technology of EllipticLabs that allows you to control your gadgets like computers, MP3 players or mobile phones without touching them. Simply point your finger at the device and move it to control navigation on the device. They call it "Human User Interface / Touchless Machine for 3D Navigation"

TACTO LESS MONITOR:
Sure, everyone is doing touch-screen interfaces these days, but this is the first time I've seen a monitor that can respond to gestures without having to touch the screen.

The monitor, based on TouchKo technology, was recently demonstrated by White Electronic Designs and Tactyl Services at the CeBIT show. Designed for applications where contact can be difficult, as for doctors who may wear surgical gloves, the screen has capacitive sensors that can read movements up to 15 cm away from the screen. The software can translate gestures into screen commands.

Touch screen interfaces are great, but everything you touch, like foreplay, can be a little tricky. Enter the wonderful children of Elliptic Labs, who work hard at implementing a touchless interface. The method of entry is, well, in thin air. The technology detects motion in 3D and does not require special worn out sensors for operation. By simply pointing to the screen, users can manipulate the object being displayed in 3D. The details are light on how this really works, but what we do know is this:
What is the technology behind it?
Obviously requires a sensor, but the sensor is not mounted or mounted on the screen. The sensor can be placed on the table or near the screen. And the hardware configuration is so compact that it can be installed on a small device like an MP3 player or a mobile phone. Recognize the position of an object from 5 feet.
WORKING:
The system is able to detect 3-dimensional movements without having to put your fingers on the screen. Its patented contactless interface does not require you to use any special sensors in your hand either. You just point to the screen (up to 5 feet away), and you can manipulate objects in 3D. The sensors are mounted around the screen that is being used, interacting in the line of sight of these sensors, the movement is detected and interpreted in movements on screen. What is to stop unintentional gestures that are used as input is not entirely clear, but it seems promising nonetheless. The best part? Elliptic Labs says its technology will be easily small enough to be deployed on cell phones and the like. Ipod touchless, anyone?

Touch-less glance at GBUI:
We've seen the futuristic user interfaces of movies like Minority Report and Matrix Revolutions where people shake their hands in 3 dimensions and the computer understands what the user wants and changes and classifies the data accurately. Microsoft's XD Huang showed how his company sees the future of the GUI at ITEXPO this past September indeed.
Touch SDK:
The Touchless SDK is an open source SDK for .NET applications. It allows developers to create multi-touch applications based on a webcam for input. User-defined color-based bookmarks are tracked and their information is published through events to SDK clients. In short, the Touchless SDK allows you to play without touching. Well, Microsoft Office Labs has just released "Touchless", a multi-touch web camera interface SDK that lets you "play untouched."
Using the SDK allows developers to offer users "a new and inexpensive way to experience multi-touch capabilities, without the need for expensive hardware or software. All the user needs is a camera," to track multicolored objects defined by the developer . Almost any webcam will work

Non-touch demonstration:
The Touch Less Demo is an open source application that anyone with a webcam can use to experience multi-touch, does not require geekiness. The demo was created using the Touch minus SDK and Windows Forms with C #. There are 4 fun demos: Snake - where you can control a snake with a marker, Defender - up to 4 players of the version of a pong game, Map - where you can rotate, zoom and move a map using 2 markers, Used to guess what .. draw!
Whats Next?
Many personal computers will likely have similar screens in the near future. But tactile interfaces are nothing new: ATMs. How about being completely out of touch? A startup called LM3Labs says it is working with leading computer manufacturers in Japan, Taiwan and the United States to incorporate touchless navigation into their laptops, called Airstrike; The system uses small cameras of integrated charge devices (CCD) integrated in each side of the keyboard to detect movements of the user.
You can drag the windows around or close them, for example by pointing and gesturing in the air over the keyboard. You should be able to purchase an Airstrike-equipped laptop next year, with the high-end independent keyboards to follow.
Any such system is unlikely to replace typing and mousing. But that is not the point. Airstrike aims to give you an occasional quick break from those activities.
CONCLUSION:
Thoughts today are again around the UI. Efforts are being made to improve technology day by day. The Touchless Touchscreen user interface can be used effectively on computers, cell phones, webcams and laptops. It may be a few years down the line, our body can be transformed into a virtual mouse, virtual keyboard and what not ? our body can be turned into an input device.
