Background Information

• 3 Technologies of Virtual Keyboard
• Projection Module
• Micro-Illumination Module TM
• Sensor Module

4
Projection Module

• Displays keyboard template onto an adjacent
  surface.
• Keyboard template formed by creating a
  holographic image with a red laser.

5
Micro-Illumination Module TM

• Projects an infrared beam of light above the
  keyboard surface.
• The light is invisible to the naked eye and
  hovers a few millimeters above the surface.

6
Sensor Module

• Detects users finger interaction with the
  infrared beam.
• Receives information and interprets the
  keystrokes.
• Sends the information back to the device such as
  a PDA, mobile phones, etc.

Benefits of the BTVKB Technologies

• Small size (equal to disposable lighter) allows
  for storage in the smallest of spaces.
• Any flat surface can become a keyboard.
• Efficient in power consumption
• Operates with high accuracy
• Low cost (around 150 now, price expected to
  decrease).
