- 2. CONTENTS : • 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
- 4. THE SYSTEM COMPRISES OF THREE MODULES:
- 5. 1 3 2
- 6. • K VKB PROJECTION SENSE BOARD SCURRY V-TYPE • J
- 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.
- 13. 19981A0533 . 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
