The document discusses touchless touchscreen technology, including touch walls that use infrared lasers to scan surfaces, touchless UIs that sense finger movements in 3D space without touching the screen, and touchless monitors that detect 3D motion without sensors. It provides examples of touchless technology inspired by Minority Report including eye tracking, gesture recognition, and motion sensing devices. The document concludes that touchless interfaces could transform bodies into virtual input devices in the future.

• TouchLess Touchscreen
• TouchLess Monitor
• Working
• Minority Report
• TouchLess SDK
• TouchLess Demo
• Advantages
• Conclusion

3. Introduction:
• Simple UI for touchless control, EllipticLabs
Innovative technology
• This unique screen is made by TouchKo, White
Electronics Designs, and Groupe 3D.
• The screen resembles the Nintendo Wii without the
Wii Controller.

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 wall:

6. Touchless UI:
• The basic idea described in the patent is that there
would be sensors arrayed around the perimeter of the
device capable of sensing finger movements in 3-D
space

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

8. 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.

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. • This sensor is then connected to a digital image
processor, which interprets the patterns of motion and
outputs the results as signals to control fixtures,
appliances, machinery, or any device controllable
through electrical signals.
• You just point at the screen (from as far as 5 feet
away), and you can manipulate objects in 3D.
ContD…

13. Touch-less -> Glimpse of gbui
• We have seen the futuristic user interfaces of movies
like Minority Report and the Matrix Revolutions
where people wave their hand in 3 dimensions and
the computer understands what the user wants and
shifts and sorts data with precision.
• Microsoft’s XD Huang demonstrated how his
company sees the future of the GUI at ITEXPO.

14. 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.

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

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

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

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

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

20. • 7. Leap Motion
LeapMotion is a motion sensor device that
recognizes the user’s fingers with its infrared LEDs
and cameras.

21. • 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.

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

23. 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.

24. Touch-less demo:
• 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
▫ Draw - the marker is used to guess what…. draw!

25. Advantages:
• Easier and satisfactory experience
• Touchless Screen
• Controlling objects
• Gesturing and cursor positioning
• No drivers required

26. 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!
