Infrared Keyboards

Infrared keyboard or Projection keyboard is the latest form of keyboard technologyInfrared keyboard or Projection keyboard is the latest form of keyboard technology.
It is a form of computer input device whereby the  image of a virtual keyboard is projected onto surface.
when a user's fingers are placed on the projected "keys", the device translates them into keystrokes.

The optical virtual keyboard was invented by IBM Engineers.

Virtual Keyboard uses a light projection of a full-sized computer keyboard on almost any surface. Used with PDA's and Smart Phones, the Virtual Keyboard provides a practical way to do e-mail, word processing and spreadsheet tasks, enabling users to leave laptops and computers at home.
VKB's adaptable technology studies the user's finger movements to interpret and record keystrokes. Because the virtual keyboard is an image projected by light, it disappears completely when not in use.
Most systems can also function as a virtual mouse.

Technology behind its working:
  • A laser projects visible virtual keyboard onto level surface.
  • A sensor or camera in the projector picks up user's finger movements.
  • Detected co-ordinates determine actions or characters to be generated, 
  • Then the keystrokes are generated as an input.
