2. INTRODUCTION
 Touchless touchscreen is a technology that uses gesturing as form of input.
It has no need of touching screen.
 This technology is high end technology, that uses hand waves and hand
flicks. The main objective behind building such technology is making it
even more comfortable and convenient for users to use their devices.
 It does not need touching of screen rather system detects hand
movements in front of it by making use of various sensors.

3. TOUCHLESS TOUCHSCREEN
 It uses gesturing as form of input.
 Pretty unique and interesting invention.
 No need of touching screen.
 It uses hand waves and hand flicks.
 Detects hand movements by using sensors

4. WORKING
 Sensors are mounted either on the screen or near the screen.
 The motion is detected and interpreted into on screen movements.
 The system is capable of detecting movements in 3-dimensions without
ever having to put your fingers on the screen.
 The device is based on optical pattern recognition using a solid state
optical matrix sensor with a lens to detect hand motions.

5. WORKING OF TOUCH SCREEN
 MAIN COMPONENTS
 TOUCH SCREEN SENSOR
 CONTROLLER
 DRIVERS

6. TOUCH SENSOR
 A touch screen sensor is a clear glass panel with a touch responsive
surface.
 The sensor generally has an electrical current or signal going through it
and touching the screen causes a voltage or signal change.

7. CONTROLLER
 The controller is a small pc card that connects between the touch sensor
and the pc.
 The controller determines what type of interface/connection you will need
on the pc.

8. TECNOLOGY BEHIND THIS
 Optical pattern recognition uses solid state optical matrix sensor
 The sensor is connected to digital image processor
 Output are obtained as signals
 Each of these sensors contains matrix of pixels
 Each pixel is coupled to photodiodes to charge storage regions

11. TECHNOLOGIES
 Air writing
 Eye sight
 Elliptic labs
 Mauz
 Leap motion
 Microsoft Kinect
 Point grab

13. GLIMPSES OF GBUI

14. ADVANTAGES
 More durable and less damage.
 Replacement is very easy.
 No drivers required
 Satisfactory Experience.
 Gestures are rich than the traditional methods.

15. CONCLUSION
 The touchless touchscreen user interface can be used in Laptops,
Computers, Mobile phones, and Webcams
 Our body can be transformed into a Virtual Mouse, Virtual Keyboard or an
Input Device.
