Virtual Keyboard

INTRODUCTION

• A Virtual Keyboard is a projection keyboard.
• A virtual keyboard is a software component that
  allows a user to enter characters. Virtual
  Keyboard is a keyboard simulation software
  running under Windows operating system.
• It is the latest software in computing
  technology.

6
Contd

• A virtual keyboard has an integrated software
  and/or hardware component which allows virtual
  keyboard users to type in characters.
• A virtual keyboard can usually be operated with
  multiple input devices, which may include an
  actual keyboard, a computer mouse, a head-mouse,
  and an eye-mouse.
• On a desktop PC, the primary purpose of a virtual
  keyboard is to provide an alternative way for
  disabled users who can not use a regular physical
  keyboard.

7
What can you do with a Virtual Keyboard?

• 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.

How does the Virtual Keyboard Work?

• The keyboard watches finger movements and
• translates them into keystrokes in the device.
• A system called the P-ISM will combine the
• virtual technology with a small video projector
• to create a portable computer about the
• size of a fountain pen.

Technology How does it work?
11
Technical Terms

• Projection Module A template is created of the
  desired interface and is projected onto the
  adjacent interface surface. This template is
  produced by illuminating a specially designed
  highly efficient holographic optical element with
  a red diode laser.
• Micro-illumination Module An infa-red plane of
  light is generated just above, and parallel to
  the interface surface. This light is invisible
  to the user and hovers a few millimeters above
  the surface.
• Sensor Module Reflected light from user
  interactions with the interface surface is passed
  through an infa-red filter and imaged onto a CMOS
  image sensor in the sensor module.

12
Reasons to use the Virtual Keyboard.

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

Uses of Virtual Keyboards

• BY PROFESSIONALS

• BY STUDENTS

• To take notes during a business meeting
• To compose a memo to employees while traveling to
  work on the train
• To do everyday work at your desk without taking
  up so much valuable space.

• To take notes while in class (no one will hear
  your keying)
• To work on a paper while in the library
• To do homework while you are on break at work

14
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
• No disturbance.
• Keyboard layouts can be changed by software
  allowing for foreign.
• High battery Life.

15
Drawbacks

• It is very costly than normal keyboards.
• Its projections does not see properly in bright
  light.

16
CONCLUSIONS

• Virtual keyboards are moreconvenient compact
  than THEQWERTY keyboards. Canestaappears to be
  the most advanced inthis class of technology.
• Thus virtual keyboards willtake typing easier,
  faster, and allmost a pleasure.
