This document discusses touchless technology as an alternative to traditional touch screens. It describes how touchless screens work using optical sensors to detect hand motions and gestures without physical contact. Examples of touchless screens and devices are given, along with their advantages like easier use and direct interaction. The conclusion suggests touchless interfaces could replace mice, keyboards and transform our bodies into virtual input devices in the future.

3. Introduction
Touch screen displays are ubiquitous world wide
Frequent touching a touch screen display can ultimately lead to
failure of the touch screen
To avoid this a simple user interface for Touch less control of
electrically operated equipment is being developed.
It is developed by Elliptic Lab

4. 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.
• Touch Wall consists of three
infrared lasers that scan a surface.

5. Touch less Touch Screen:
• The Touchless technology are being used in many forms in
many different places.

6. TOUCH LESS MONITOR:
• The monitor, based on technology from
TouchKo was recently demonstrated by
White Electronic Designs and Tactyl
Services at the CeBIT show.
• The technology detects motion in 3D
and requires no special worn-sensors
for operation.

7.  This is based on optical pattern recognition using a solid state optical
matrix sensor
 This sensor is then connected to a digital image processor, which
interprets the patterns of motion and outputs the results as signals

8.  In each of these sensors there is a matrix of pixels
 Each pixel is coupled to photodiodes incorporating charge storage regions.

9. Working:
• The system is capable of detecting
movements in 3-dimensions without
ever having to put your fingers on the
screen.
• 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.
• The device is based on optical pattern
recognition using a solid state optical
matrix sensor with a lens to detect hand
motions.

11. 9 Minority Report
Inspired Touchless Technology:
• 1. Tobii Rex:
Tobii Rex is an eye-tracking device from Sweden which
works with any computer running on Windows 8. The device
has a pair of infrared sensors built in that will track the user’s
eyes.

12. • 2. Elliptic Labs
EllipticLabs allows you
to operate your computer without
touching it with the Windows 8
Gesture Suite.

13. • 3. Airwriting
Airwriting is a technology
that allows you to write text
messages or compose emails by
writing in the air.

14. • 4. EyeSight
eyeSight is a gesture
technology which allows you to
navigate through your devices by
just pointing at it.

15. • 5. Mauz
Mauz is a third party device that turns your iPhone into a
trackpad or mouse.

16. • 6. PointGrab
PointGrab is something similar
to eyeSight, in that it enables
users to navigate on their
computer just by pointing at it.

17. • 8. Myoelectric Armband
Myoelectric armband or
MYO armband is a gadget
that allows you to control your
other bluetooth enabled devices
using your finger or your hands.

18. • 9. Microsoft Kinect
It detects and recognizes a user’s body movement and
reproduces it within the video game that is being played.

19. 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.

20. Advantages:
• Easier and satisfactory experience
• Direct pointing to the objects
• Touchless Screen
• Fast
• Controlling objects
• Gesturing and cursor positioning
• No drivers required

22. Conclusion:
• Today’s thoughts are again around user interface.
• The Touch less 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. Our body may be turned
in to an input device!
