About Bluetooth Keyboard

In most definitions, a Bluetooth® keyboard is one that uses the Bluetooth® wireless protocol to connect the keyboard to a mobile device, such as a cell phone or a Personal Digital Assistant .

Essentially, any standard QWERTY keyboard that makes use of Bluetooth® could be considered a Bluetooth® keyboard, but the most common definitions limit a Bluetooth® keyboard to one that connects to a small, mobile device that doesn't contain its own keyboard.

In most cases, the Bluetooth® keyboard, which may include a touch pad too, is actually one that can fold up when it isn't in use. This makes it especially easy to carry along with a mobile device.

Keep in mind that most Bluetooth® keyboards are not as large as the standard size you'll see with a computer keyboard or even with a laptop computer.

Sometimes, a Bluetooth® keyboard doesn't involve a physical keyboard.

For example, I-Tech makes the Virtual Laser Keyboard, which projects a virtual keyboard using laser light onto a table or desk.

Some desktop computer manufacturers also connect their wireless keyboards to the computer using Bluetooth® technology . This isn't the standard definition of a Bluetooth® keyboard because it's used with a computer, rather than a mobile device.
