Virtual Keyboard

Virtual Keyboard

After surfing through Internet I found a new product called "Virtual Keyboard" by Canesta Inc.
Basically It is a QWERTY keyboard which doesn't have buttons but it have images of buttons.

It contains a projector which projects the images of buttons of keyboard and you just have to touch the image of button to use the button.


Its cool, in future it have so many uses like in laptops, it will only have a small projector, a track pad and screen.

NOW HOW PROJECTOR WORKS?
This projector have sensor, whenever a finger is touched to button, it blocks the path of infrared beam, infrared light gets reflected back and sensor senses it.
Its only due to reflection of light, sensor gets its input.

CONNECTING TO SYSTEM
USB and Bluetooth are general method which will be used to connect it with system.
