Bluetooth keyboards connect to the computer through a short-range wireless connection. Unlike other wireless keyboards, they can be used from any angle and are not cut off by physical barriers. Most Bluetooth keyboards can be detected from a 10-meter radius. They are commonly used with mobile computers, or during presentations where the computer has to be operated from across a room.
Types of Bluetooth Keyboards
Kinds of Bluetooth Keyboards include the following:
Desktop Bluetooth keyboards
Desktop Bluetooth keyboards are designed for desktops or stationary computers.
They are the same size as standard keyboards and usually have a full key layout.
They can easily be transferred to other desktops and portable devices.
Portable Bluetooth keyboards
Portable Bluetooth keyboards can be folded or rolled up for transport and storage.
They are designed for PDAs and pocket PCs, where the touch screen provides limited input.
Some models include fold-up docks that hold the device upright while typing.
Laser Bluetooth keyboards
Laser Bluetooth keyboards project a virtual keyboard from a laser light onto any flat surface.
They are ideal for working with limited desk space or when there are no desktops available.
They usually include clicking sounds to simulate typing on an actual keyboard.
Choosing Bluetooth Keyboards (Buying tips)
Power: Choose a Bluetooth keyboard with long-lasting rechargeable batteries. Look for that you can connect to the computer for recharging. Make sure you can turn off power-consumng features such as sounds and backlit keys. Response times: Choose a Bluetooth keyboard with a consistent response time. You should be able to see your input on the screen with little or no delay. Make sure the reception does not weaken or slow down as you move farther within the range.
