Keyboard? :

What can you do with a Virtual Keyboard?

The ground breaking Virtual Keyboard,

uses state of the art infrared & laser

technology to project a full-size keyboard

onto any flat surface.For the first time

mobile device users can actually type

normally on a virtual keyboard , enabling

them to work quickly and effectively,

taking the pain and frustration out of

existing minuscule keyboards and

handwriting recognition software.

How does the Virtual Keyboard Work?

:

How does the Virtual Keyboard Work?

The keyboard watches finger movements

and translates them into keystrokes in the

device. A system called the P-ISM will

combine the virtual technology with a

small video projector to create a portable

computer about the size of a fountain pen.

Technology How does it work?

Technical Terms :

Technical Terms Projection Module – A

template is created of the desired interface

and is projected onto the adjacent interface

surface. This template is produced by

illuminating a specially designed highly

efficient holographic optical element with

a red diode laser. Micro-illumination

Module – An infa-red plane of light is

generated just above, and parallel to the

interface surface. This light is invisible to

the user and hovers a few millimeters

above the surface. Sensor Module –

Reflected light from user interactions with

the interface surface is passed through an

infa-red filter and imaged onto a CMOS

image sensor in the sensor module.
