Cordless Vs. Optical Mouse

A cordless mouse produces less clutter and gives the user a wider range of motion.

The majority of computer users rely on a keyboard and mouse for input. However, there are many different types of computer mice besides the standard models that come bundled with some new computers. Optical and cordless mice both offer advantages over a conventional mouse, with a tracking ball and cord. However, each type of mouse is only best for certain users.

Technology

Both optical and cordless mice use advanced technology to replace one of the physical components of a conventional mouse. A cordless mouse uses a short-range radio signal, often through the Bluetooth wireless protocol, to communicate with the nearby computer. Computers with built-in Bluetooth can detect a mouse automatically, while others may need a USB dongle or additional receiver installed. Optical mice use a miniature camera and light to track motion across a surface, replacing the rolling ball on older mice with a more reliable, precise tracking mechanism.

Advantages

Each type of mouse has its own advantages. Cordless models reduce clutter and also free up computer ports for connecting other devices. They also allow the user to control the computer from a greater distance and provide a greater range of motion, since there is no cord to limit hand and wrist motion. An optical mouse gives more precise control over the on-screen cursor. It also removes the need to disassemble and clean the tracking mechanism, as with tracking ball models that can collect dust and debris over time, resulting in poor control.

Drawbacks

One key drawback of optical or cordless mice is their price, which is higher than a traditional mouse. Cordless models have the added burden of using batteries, which require occasional replacement or recharging. While an optical mouse is more sensitive and precise than a rolling ball model, it is not as precise as a laser mouse. Optical mice may also have trouble tracking on dark surfaces, requiring a mouse pad or light-colored desk surface to work properly.

Ergonomics

Optical mice with cords are comparable to traditional rolling ball models in terms of ergonomics. However, cordless mice can present a distinct advantage. Because the user can operate the mouse from farther away from the computer, cordless mice promote better posture. They also allow the user to relax the arm that holds the mouse, controlling it in a more comfortable position that causes less muscle and tendon fatigue.

Alternatives

There are several other alternatives to cordless and optical mice. Laser mice, which come with and without cords, are even more accurate, but cost more as well. Tracking balls, which feature a rolling ball in a stationary housing, are even better ergonomically and use less space on the desktop. Finally, trackpads can accept multiple types of input from finger gestures, making them comparable to multi-button mice but without the need to lift or slide the input device itself.
