A virtual keyboard usually describes a hardware component that allows a user to input data, although there are also software "virtual keyboards".
For the purposes of this product tip, we will be discussing the hardware versions.
A virtual keyboard can usually be operated with multiple input devices, which may include an actual keyboard, a computer mouse, a headmouse, and an eyemouse. On a desktop PC, the primary purpose of a virtual keyboard is to provide an alternative mechanism for disabled users that can not use a physical keyboard, or to save space.
Virtual keyboards can be onscreen or projected:
- Virtual keyboards with touchscreen keyboard layouts or sensing areas
- Optically projected keyboard layouts or similar arrangements of "keys" or sensing areas optically detected human hand and finger motions
The Future Has Arrived - The Bluetooth Laser Virtual Keyboard.
The Virtual Laser Keyboard (VKB) is a revolutionary accessory (The only keyboard that operates in total darkness - see the picture) for Blackberry, Smartphone, PDA, MAC & Tablet PC.
It has a cable-free connection with Bluetooth compatible enabled PDAs, Smartphones, laptops or PCs. The device leverages the power of laser and infrared technology and projects a full-size keyboard onto any flat surface. As you type on the laser projection, detection technology based on optical recognition enables the user to tap the images of the keys, complete with realistic tapping sounds, which feed into the compatible Bluetooth-enabled PDA, Smartphone, laptop or PC. |
Unlike many small snap-on keyboards for PDAs, the VKB provides a full-size QWERTY keyboard. It is also smaller and more convenient to use than the folding-type keyboards made by some manufacturers and similar to them in functionality.
You'll be turning heads the moment you pull this baby from your pocket and use it to compose an e-mail on your bluetooth enabled PDA or Cell Phone. With 63 keys and and full size QWERTY layout theVKB can approach typing speeds of a standard keyboard... in a size a little larger than a matchbook.
To charge the battery, there's a power adapter port on the back as well as a communication port, which are both covered by an attached rubber cover. If you're running low on juice, a small LED on top blinks orange to alert you, while another LED blinks blue for Bluetooth. Aside from the aforementioned protective case, Celluon includes an AC adapter, an installation CD, and a Quick Guide in the box.
