  • 3 Technologies of Virtual Keyboard
    • Projection Module
    • Micro-Illumination Module TM
    • Sensor Module
projection module
Projection Module
  • Displays keyboard template onto an adjacent surface.
  • Keyboard template formed by creating a holographic image with a red laser.
micro illumination module tm
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.
sensor module
Sensor Module
  • Detects user’s 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).
