2 CONTENTS INTRODUCTION WHAT IS TOUCH-SCREEN DEVICES? ABOUT THE TOPIC
3 INTRODUCTION Touch screen displays are ubiquitous world wideFrequent 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 INTERFACEA 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 interfaceTouch less SDK Touch less demo Touch wall
13 TOUCHLESS MONITOR This monitor is made TouchKoOur 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
