This document discusses different types of virtual keyboards, including a projected keyboard that displays on surfaces using sensor technology, a sense board that detects muscle movements in the palm, and a scurry glove that allows typing in empty air by moving hands. It describes the advantages of virtual keyboards like portability and usability in medical settings, and drawbacks like difficulty adjusting and high cost. The document concludes that virtual keyboards can make typing easier, faster, and more enjoyable.

• Introduction
• Virtual Keyboard Technology
• Different Types Of Virtual Keyboard
• Applications
• Advantages
• Drawbacks
• Conclusion

3. • The first virtual keyboard was invented by IBM engineers in 1992.
• Virtual keyboard Is a flashlight-size gadget that projects an image of a
keyboard on surface.
• It uses sensor technology and artificial intelligence.
• The device detects movement of fingers,and make the proper key-
stroke

7. VKB PROJECTION

8. SENSE BOARD
.
Here the image is not projected on to any
surface.
Muscle movements in the palm are
sensed
.
Consists of two rubber pads that slips
onto user’s hand

9. SCURRY
.
Next generation glove like, wearable device
Operates computer by moving two hands in
empty air
Allows user to punch in letters without a
keyboard, scroll up and down and control a
cursor

10. V-TYPE
Detects key strokes in the air with a data
glove
Active finger tracking method is used

11. ..
In Operation theatres
Fingerprint security
Used with smart phones,email,word processing,spreadsheets tasks
etc..
Gaming Control
Muscial applications
TV remote control

12. ADVANTAGES
M
33
Laser can be projected on any surface
High battery life
Plug and play device
No driver software necessary
The typing does not requires a lot of force
It can be useful in places like operation theatres where low noise is essential.

.
VKB is hard to get used to
Typing in thin air requires a little practice
Projected keyboard should not be used in bright room
The devices are very costly

14. .
.
Easy to carry and store
Based on a true-3D optical range camera
Thus virtual keyboards will make typing easier, faster and almost a pleasure.
It uses 6th Sense Technology Device which does not depends on surface
