Laser Keyboard and Mouse Reviews

The laser keyboard and mouse are the ultimate technology when it comes to computer science. The wireless laser keyboard and mouse are virtual parts of peripheral hardware that can be projected and touched on any type of surfaces. This type of keyboard is also called projection keyboard. This technology is able to record the finger movements and translate them into keystrokes in the device, although there are no physical keys. The first virtual keyboard was invented by IBM in 1992.
The laser keyboard projection is sort of an image of a real keyboard but which does not really exist physically. Most systems may be used as a virtual mouse or virtual piano.
This is how these devices work: the visible virtual keyboard is projected onto the surface by a laser or with some systems, by a beamer. The projecting device is equipped with a sensor or sensorial camera that picks up the finger movements and touches and when these are detected, they are transformed into actions or characters.
Some systems use an invisible infrared as a second beam to create a wireless laser keyboard projection. This type of product projects an invisible infrared beam above the virtual keyboard on which one uses the fingers to make keystrokes on the projected keyboard. The beam is equipped with sensors and cameras that translate the place when the infrared light was broken into characters or actions.

Laser Keyboard and Mouse Reviews

The virtual keyboard and mouse is the only computer peripheral part that works in complete darkness and it is suitable for Blackberries, Smartphones, PDAs, and Mac & Tablet PCs. The device projecting the keyboard comes in different sizes but they are normally the size of a small mobile phone, 90 x 34 x 24 mm. They have the advantage that users can write texts or e-mails easier and faster, just as with a usual keyboard and that when it is turned off it disappears completely.
The projection keyboard may be used on PDA’s, MAC compatible laptops, Tablet PCs, industrial environments, mobile phones, clean rooms, test equipment or in sterile and medical environments.
The market provides all types of accessories for virtual keyboards. One can get a portable charger for reasonable costs and extra batteries. There are also converter cables available for those whose devices are not equipped with serial ports. The Bluetooth Dongle is a new technology that allows users to connect their virtual keyboards with other devices such as PC’s or mobile phones. Those who travel around the world may purchase an international adapter plugs set to make sure they may use their keyboard in any country in the world.
The prices of the projection keyboards vary depending on the type of technology used, if there are accessories included and by manufacturer. The costs range from a little over $100 and can reach $200 or even more.
The recent IT technology made it possible that such devices exist. The laser keyboard and mouse are perfect for those who have trouble typing texts on their mobile phones or PAD’s or for those who would need such a device in a more special environment such as sterile and medical places.
