VR Interfaces: Virtual Keyboard


Overview of Virtual Keyboard
The virtual laser keyboard first appeared in mid 2005, and is a product of machine vision and projection technology. The emitter itself is about the size of a small mobile phone, and so can be discretely attached to any handheld device.

The virtual keyboard works by using a scanning laser to project a red-light keyboard image onto any flat surface. It then uses an infra-red scan based on optical recognition to detect objects such as fingers, passing through the space where the keys would be if they were physical, and records a ?keypress?.

The emitter even emits an optional clicking sound, when a key is pressed, which is highly useful for configuring sensitivity so it does not record keypresses you did not intend ? such as fingers too far from the keyboard.

Designed to be fitted to mobile phones, laptops, or tablet PCs, to provide a full size input mechanism, a virtual keyboard can be fitted to any PC. Because of the way it works it is also ideal for sterile environments and clean rooms.

The virtual laser keyboard, tends to use a neural net based learning approach, as a by-product of optical recognition, and gets to know how its regular user prefers to type, greatly increasing efficiency the more it is used.

Once the keyboard is finished with, and switched off, the laser projection winks out, and it can be slipped into the user?s pocket or purse, quite happily.
