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

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?

• 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.

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.
