The document discusses touchless touchscreen user interfaces. It describes how touchless technology works using optical sensors to detect hand motions from a distance without physical contact. The technology allows users to control and manipulate objects on screen through gestures in 3D space. Applications mentioned include touchless monitors, Microsoft Kinect, airwriting, and myoelectric armbands. Key advantages are avoiding screen degradation, ability to control from a distance, and usability for disabled users.

3.  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 LESS MONITOR:
 The Touchless technology are being used in many forms in
many different places.
 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.

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

6.  The technology detects motion in 3D and requires no
special worn sensor for operation.
 By simply points to the screen of users and user can
manipulate the object being displayed in 3D.
 In touchless touch screen sensor is required but the
sensor is neither hand mounted nor present on the
screen

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

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.

9.  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
 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.  Optical matrix sensor
3D Navigation of Hand Movements

12.  No de-sensitization of screen.
 Can be controlled from a distance.
 Usefull for physically handicapped people.
 Easier and satisfactory experience.
 Gesturing and cursor positioning.
 No drivers required
ADVANTAGES

13. o Today’s thoughts are again around user interface.
o The Touch less touch screen user interface can be used
effectively in computers, cell phones, webcams and laptops
o 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!
