 INTRODUCTION
 WHAT IS TOUCH-SCREEN DEVICES?
 ABOUT THE TOPIC

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. WHAT IS TOUCH SCREEN ?
 A touch-screen is an electronic visual display that the
user can control through simple or multi-touch gestures
by touching the screen with a special stylus/pen and-or
one or more fingers.
 The touch-screen enables the user to interact directly
with what is displayed, rather than using a mouse ,
touchpad, or any other intermediate device

5. TOUCHLESS TOUCHSCREEN USER INTERFACE
 A simple user interface for Touchless control of
electrically operated equipment is being developed by
Elliptic Labs
 This technology lets you control our gadgets like
Computers, MP3 players or mobile phones without
touching them.
 This unique screen is made by TouchKo, White
Electronics Designs, and Groupe 3D.

6.  It works by detecting your hand movements in front
of it.
 This system depends on hand and or finger motions, a
hand wave in a certain direction
 The sensor can be placed either on the screen or near
the screen

7.  The device is based on optical pattern recognition
using a solid state optical matrix sensor with a lens to
detect hand motions
 This sensor is then connected to a digital image
processor, which interprets the patterns of motion
 Outputs results as signals to control fixtures,
appliances, machinery, or any device controllable
through electrical signals

8. WORKING
 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.
 The sensor can recognize the position of an object
from as 5 feet
 System is capable of detecting movements in 3D
without ever having to put your fingers on the screen

9.  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.
 Just point at the screen (from as far as 5 feet
away),and you can manipulate objects in 3D.
 Gestures are translated into screen commands

10. TOUCH SENSOR
 Touch sensor is a clear glass panel with a touch
responsive area.
 It is placed over a display screen

11. SCREEN COMMANDS

12. APPLICATIONS
 Touch less monitor
 Touch less user interface
 Touch less SDK
 Touch less demo
 Touch wall

13. TOUCHLESS MONITOR
 This monitor is made TouchKo
 Our hand doesn’t have to come in contact with the
screen at all, it works by detecting your hand
movements in front of it.
 Point your finger in the air towards the device and move
it accordingly to control the navigation in the device
 Designed for applications where touch may be difficult,
such as for doctors who might be wearing surgical
gloves
