Differences between bluetooth and optical mouse
Bluetooth
Almost all of the computer users today are dependent on a mouse and many have already gone cordless. This has been made possible by different wireless technologies and the Bluetooth is one of them.
Where most RF operated mice have range up to 6 feet, a typical Bluetooth mouse usually has a range of up to 32 feet, which makes our working style more convenient and flexible - giving us freedom to move about with ease. It is a great advantage for business users for presentations.
A Bluetooth mouse can easily and quickly connect to a computer, without the need of wires, which means that no time is wasted in untangling the mouse from any other cables. Some Bluetooth mice can neatly fit into one's pocket because they are so small and lightweight, this also gives ease of travel. These mice are sensitive to surfaces, so using them almost everywhere is possible, be it your bed, desk, rough surface, etc.
Many laptop PCs come with an integrated Bluetooth device that allows mouse to connect to the Laptop. Laptop and Desktop PCs without a built-in Bluetooth can have an external USB Bluetooth adaptor plugged in.
A Bluetooth mouse, which works with any operating system such as Mac, Linux, etc are easily available. It also comes with different features such as optical sensors, programmable buttons, clickable scroll wheels and ergonomic design.
Bluetooth mice are probably the best option because of their cost, flexibility, scalability and mobility.
Optical Mouse
Unlike a Bluetooth mouse, an optical mouse uses an electrical cord that connects to either PS2 or USB ports. A disadvantage of this is that it can crowd the workplace with its cable and also reduce the freedom with which the user can use the mouse.
On the other hand, one of the major advantages of an optical mouse is the elimination of the mouse ball that needs regular cleaning to remove accumulated dust and dirt on the ball. Since an optical mouse has no moving parts, no maintenance or cleaning is required.
Another benefit of this mouse is the smooth and more accurate performance than prior mouse technologies.
There are no special PC requirements for optical mouse and its installation only requires us to simply plug the device in to the computer. In case of a Bluetooth mouse, either integrated Bluetooth device is needed or an external USB Bluetooth adaptor is required.
A similarity with the Bluetooth technology is that a mouse pad is not usually required for this mouse and it can also be used on flat, rough and uneven surfaces.
As technology evolved, optical mice have become cheaper. A good optical mouse can be purchased for 15-25 US$ only.
