TOUCHLESS TOUCH SCREEN DEPARTMENT OF ELECTRONICS & COMMUNICATION ENGINEERING A SEMINAR ON: TOUCHLESS TOUCH SCREEN PRESENTED BY: A.Vinay kumar reddy (118T1A0449)

CONTENTS Introduction Touch less monitor What is the technology behind it? Working Touch-less SDK Touch-less demo Touch wall Conclusion

Introduction: 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 Elliptic Labs innovative technology lets you control your gadgets like Computers, MP3 players ,mobile phones without touching them.

Cont’d: This touch less touch screen depends on hand or finger movements. With this system your hand doesn’t have to come in contact with the screen at all.

Touch less monitor In this a monitor that can respond to gestures without actually having to touch the screens.

What is the 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 on the 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.

WORKING: The system is capable of detecting movements in 3-dimensions without ever having to put your fingers on the screen.it does not need any special sensors connect with your hand.

Touch-less SDK: The Touch less SDK is an open source SDK for .NET applications. 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: Touch less demo is open source application, that any one with a web cam can use to experience multi touch. The demo was created using the Touch less SDK and Windows Forms with C#

Touch wall: Touch Wall refers to the touch screen hardware setup itself; the corresponding software to run touch wall which is built on a standard version of Vista, is called Plex. similar to Microsoft surface a multi-touch table computer that was introduced in 2007 Touch Wall consists of three infrared lasers that scan a surface

Touch wall

What’s next?? 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.

CONCLUSION: Today’s thoughts are again around user interface. Efforts are being put to better the technology day-in and day-out. The Touch less touch screen user interface can be used effectively in computers, cell phones, webcams and laptops.
