INTRODUCTION

  • Small and fast
  • Full-size virtual keyboard projected and touched on any surface.
  • Watches your fingers move and translates that action into keystrokes in the device.
  • Uses sensor technology and artificial intelligence to let users work on any flat surface.
INTRODUCTION

Virtual Keyboard is another example of today’s computer trend of ‘smaller and faster’.

A Virtual (projection) keyboard is a full-size virtual keyboard projected and touched on any surface.

The keyboard watches your fingers move and translates that action into keystrokes in the device.


The virtual keyboard technology uses sensor technology and artificial intelligence to let users work on any flat surface as if it were a keyboard.

ABSTRACT

  • Uses sensor technology
  • Portable
  • Let users work on any surface as if it were a keyboard
  • Uses light to project a full-sized computer keyboard onto almost any surface, and disappears when not in use.
ABSTRACT

Computing is now not limited to desktops and laptops, it has found its way into mobile devices like palm tops and even cell phones. But what has not changed for the last 50 years is the input device, the QWERTY keyboard.

Virtual Keyboard uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard.

Virtual Devices have developed a small gadget that projects an image of a keyboard on any surface and let’s people input data by typing on the image.

The Vir(ve)tual Keyboard uses light to project a full-sized computer keyboard onto almost any surface, and disappears when not in use.

NEED OF VIRTUAL KEYBOARD

  • uses the infrared & laser technology to project a full-size keyboard onto any flat surface
  • So you can use it almost anywhere
  • Prevents your username or password from being stolen
  • Not restricted to the ‘QWERTY’ touch-typing paradigm
  • Adjustments can be done to the software to fit other touch-typing paradigms as well, such as the ‘DVORAK’ keyboard
NEED OF VIRTUAL KEYBOARD

The Virtual Keyboard uses the infrared(fraid) & laser technology to project a full-size keyboard onto any flat surface. So you can use it almost anywhere which assists in convenience.

A virtual keyboard prevents your username or password from being stolen, especially while using public computers, such as those available in Internet cafes. Every time a page is refreshed, the keyboard is too. So they are useful from the security point of view in Banks, ATM’s.

The Virtual Keyboard does not only provide the ‘QWERTY’ format as adjustments can be done to the software to fit other touch-typing formats as well, such as the ‘DVORAK’ keyboard.

TECHNOLOGY

  • The pattern projector (projection module)
  • IR-light source (micro-illumination module)
  • The sensor module
THE TECHNOLOGY of LASER PROJECTION VIRTUAL KEYBOARD

This system has three modules:

1.The pattern projector (projection module)

2.IR-light source (micro-illumination module)

3.The sensor module

Projection module

  • Presents the image of the keyboard of the system.
  • The projected image is that of a standard QWERT keyboard
  • Includes all the keys and control functions as in the keyboard
The Projection module printed image presents the image of the keyboard of the system.

This image can be projected on any flat surface.

The projected image is that of a standard QWERTY keyboard, with all the keys and control functions as in the keyboard.

Projection Module


This image is produced by illuminating a specially
designed highly efficient
optical element with a red
diode laser.

MICRO-ILLUMINATION MODULE

MICRO-ILLUMINATION MODULE

The Infrared Light Source emits a beam of infrared light . This light beam is designed to overlap the area on which the keyboard pattern or printed image resides. This helps in recognizing the hand movements and the pressing of keys .

MICRO-ILLUMINATION MODULE

  • emits a beam of infrared light
  • This light beam is designed to overlap the area
  • helps in recognizing the hand movements and the pressing of key
MICRO-ILLUMINATION MODULE

The Infrared Light Source emits a beam of infrared(fared) light . This light beam is designed to overlap the area on which the keyboard pattern or printed image resides. This helps in recognizing the hand movements and the pressing of keys .

Sensor module

  • serves as the eyes of this Keyboard technology
  • Operates by locating the user's fingers
  • Reflected light from user interactions with the interface surface is passed through an infra-red filter
  • imaged onto a CMOS image sensor in the sensor module
Sensor module

The Sensor Module serves as the eyes of this Keyboard technology . The Sensor Module operates by locating the user's fingers in 3-D space and tracking the intended keystrokes, or mouse movements. Reflected light from user interactions with the interface surface is passed through an infra-red filter and
imaged onto a CMOS image
sensor in the sensor module.

WORKING

  • two projections onto the flat surface in front of the projector
  • red holographic laser projection
  • A few mm above the red projection is an invisible infrared (IR) projection
  • When you press a key, the IR projection above the key is bounced back into the projector
HOW IT's WORKING

There are actually two projections onto the flat surface in front of the projector. The projection you can see is the red holographic laser projection. A few millimeters above the red projection is an invisible infrared (IR) projection. When you press a key, the IR projection above the key is bounced back into the projector that interprets from the angle which key was actually pressed.The standard projector connects to a computer either by Bluetooth or through a standard USB connector.

How does it work ?

This is a diagram to allow u understand better

FEATURES

  • Can do work in darkness
  • Wireless
  • Compact size keyboard
  • Rechargeable battery
  • Allow the convenience full-size typing in tiny factor

USES OF VIRTUAL KEYBOARD

  • To make notes as no one will hear your keying sound
  • useful to carry being small in size and lighter in weight
  • It is useful in hospitals where low noise is essential
  • It can be use in gaming control and TV remote control
USES OF VIRTUAL KEYBOARD

To make notes during smart classes, business meeting and in library as no one will hear your keying sound.
For those people who travel a lot , it is useful to carry being small in size and lighter in weight , even you can put it in your shirt’s pocket.
It is useful in hospitals where low noise is essential.
It can be use in gaming control and TV remote control.

ADVANTAGES

  • Portability, Accuracy , Flexibility
  • Speed of text entry
  • Noise less than conventional keyboards
  • easing the strain on wrists and digits
  • water proof
  • Maintenance of the laser keyboards is much easier

DISADVANTAGES

  • Tactile feel is not possible
  • Dirty screens
  • Virtual keyboards is hard to get used to
  • It is very costly ranging from 150-200 dollars
  • The room in which virtual keyboard is used should not be very bright so that the keyboard is properly visible

FUTURE SCOPE & IMPLEMENTATIONS

  • embedded into ATM’s
  • used into space crafts as they are very lighter and smaller
  • embedded into digital lockers
FUTURE SCOPE & IMPLEMENTATIONS

Laser keyboards can be embedded into ATM’s.
Laser keyboards can be used into space crafts as they are very lighter and smaller.
It can be embedded into digital lockers into banks, hostels for entering passwords and digital door lockers based on passwords.

CONCLUSION

  • uses sensor technology and artificial intelligence
  • to let users work on any surface as if it were a keyboard
  • provide the convenience of compactness with the advantages of a full-blown QWERTY keyboard
  • designed for anyone
  • make typing easier, faster, and almost a pleasure
THIS IS MY CONCLUSION FOR VIRTUAL KEYBOARD

Virtual Keyboard uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard. Projection key boards or virtual key boards claim to provide the convenience of compactness with the advantages of a full-blown QWERTY keyboard. Virtual Keyboard is designed for anyone who's become frustrated with trying to put information into a handheld but doesn't want to carry a notebook computer around.
Thus virtual keyboards will make typing easier, faster, and almost a pleasure.
