What is a Virtual Keyboard?
  • A Virtual Keyboard is a projection keyboard
  • that is projected
  • and touched on any surface.

3
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.

4
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.

5
Technology How does it work?

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.

7
Reasons to use the Virtual Keyboard.
  • It takes up less desk space than a conventional
    keyboard.
  • When connected to your handheld computer it is
    more convenient to carry around than your laptop.
  • You could use it with your desktop, laptop or
    handheld computer.

Uses of Virtual Keyboards
  • By Professionals
  • By Students
  • To take notes during a business meeting
  • To compose a memo to employees while traveling to
    work on the train
  • To do everyday work at your desk without taking
    up so much valuable space.
  • To take notes while in class (no one will hear
    your keying)
  • To work on a paper while in the library
  • To do homework while you are on break at work
