INTRODUCTION
Virtual keyboard is a small java application that lets you easily create multilingual text content on almost any existing platform and output it directly to web page.
Virtual keyboard uses sensor technology and artificial intelligence to let users work on any surface as if it were a keyboard.
TYPES OF KEYBOARDS
101-key Enhanced keyboard
104-key Windows keyboard
82-key Apple standard keyboard
108-key Apple Extended keyboard
BASIC TYPES OF KEYS
1.Typing keys 2.Numeric keypad 3.Function keys 4.Control keys
Difficulties Of Ordinary Keyboard
Muscular Injuries due to more finger or hand movements
More space required
Cables required
Noisy
VIRTUAL TYPING
Virtual Devices have developed a flashlight-size gadget that projects an image of a keyboard on any surface and let’s people input data by typing on the image. The device detects movement when fingers are pressed down. Those movements are measured and the device accurately determines the intended keystrokes and translates them into text.
VIRTUAL TYPING DEVICES
This is a set of clips that fit into your hand and try to sense the motion of the fingers and the hands (wrist) and translate them into keystrokes. This system comprises of three modules, the sensor module, IR-light source and the pattern projector .The device detects movement when fingers are pressed down. Those movements are measured and the device accurately determines the intended keystrokes and translates them into text.
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.
