The document describes a virtual keyboard, which projects a full-sized keyboard onto any flat surface using infrared and laser technology. This allows mobile device users to type normally without small, cramped keyboards. The virtual keyboard is contained in a small device the size of a fountain pen that tracks finger movements to type. It can project the keyboard wirelessly using Bluetooth or optically detect typing on any surface. This provides benefits over physical keyboards like portability, lack of need for a flat surface, and reduced risk of repetitive strain injuries.

1. VIRTUAL KEYBOARD

2. A Virtual Keyboard
is a projection
keyboard
that is projected
and touched on any
surface

3. The ground breaking Virtual Keyboard,
uses state of the art infrared & laser technology to
project
a full-size keyboard onto any flat surface.
For the first time mobile device users can actually
type normally on a virtual keyboard , enabling them
to work quickly and effectively, taking the pain and
frustration out of existing minuscule keyboards and
handwriting recognition software.

4. Introduction:-
• Key in device.
• Roughly Size of a Fountain pen.
• Uses Laser technology to
project keys.
• Camera Tracks the finger
moments of the typist.

5. • User operates by typing on or
within a wireless or optical
-detectable surface or area
rather than by depressing
physical keys.
• Proved nightmare for users
• Way to eliminate finger cramping

6. What Actually it is:-
• Keyboard that a user operates by
typing (moving fingers) on or within a
wireless or optical-detectable
surface or area rather than by
depressing physical keys.

7. Technologies used:-
• In one technology, the keyboard is
projected optically on a flat surface
and, as the user touches the image of
a key, the optical device detects the
stroke and sends it to the computer.
• In another technology, the keyboard is
projected on an area and selected
keys are transmitted as wireless
signals using the short-range
Bluetooth technology.

8. With either approach, a virtual
keyboard makes it possible for
the user of a very small smart
phone or a wearable computer to
have full keyboard capability.
Theoretically, with either
approach, the keyboard can be in
space and the user can type by
moving fingers through the air!

Virtual Keyboard

10. When connected to your handheld
computer it is more convenient to
carry around than your laptop.
It takes up less desk space than a
conventional keyboard.
You could use it with your desktop,
laptop or handheld computer.

11. Advantages:-
• Portability
• Accuracy
• Speed of text entry
• Lack of need for flat or large typing surface
• Ability to minimize the risk for repetitive
strain injuries
• Flexibility
• Keyboard layouts can be changed by
software allowing for foreign or Alternative
keyboard layouts.
