Hi I need full documentation of touch-less touchscreen user interface for my technical seminar.

abstract
It was a touch screen, which initially created great disturbance. In such days when you have to be fiddle with the touch screen and starts scratched. Touch screen displays are ubiquitous across the globe. Before touching a touchscreen display, touching the touchscreen display with one finger can result in the result of the gradual de-sensitization of the touchscreen and eventually the touchscreen may fail.

To prevent this, a simple user interface is being prepared for the touchless control of the electrically operated devices. Ellipticalabs Innovative Technology lets you control your gadgets like computers, MP3 players or mobile phones without touching the gadget. A simple user interface for the touchless control of electrically operated devices, unlike other systems which are dependent on distance for sensor or sensor selection, this system relies on hand or finger motions, a hand wave in a certain direction Or in a field, a hand shock or hold in an area or point out, for example, with a finger.

The device is based on optical pattern recognition by using a solid-state optical matrix sensor with a lens to detect motion of the hand. This sensor is then connected to a digital image processor, which explains the patterns of motion and outputs the results so that any device controlled through fixtures, equipment, machinery or electrical signals can be controlled.
