INTRODUCTION
Virtual Keyboard is just another example of today’s computer trend of ‘smaller and faster’
.
VIRTUAL KEYBOARD
Virtual Keyboard uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard.
The Virtual Keyboard uses light to project a full-sized computer keyboard onto almost any surface, and disappears when not in use.
Sensor module
The Sensor Module serves as the eyes of the Keyboard
Perception technology .
The Sensor Module operates by locating the user's fingers in 3-D space and tracking the intended keystrokes, or mouse movements.
IR-light source
The Infrared Light Source emits a beam of infrared light .
This light beam is designed to overlap the area on which the keyboard pattern projector or printed image resides.
This helps in recognizing the hand movements and the pressing of keys
CONCLUSION
Virtual key boards claim to provide the convenience of compactness with the advantages of a QWERTY keyboard.
virtual keyboards will make typing easier, faster, and almost a pleasure.
