There are several types of computer mice, with optical and laser being among the most common. Optical mice detect less detail and provide more precise and accurate movement. Laser mice detect more detail and can be used on a wider variety of surfaces, but are more sensitive to small movements. Microsoft Arc Touch Mouse hosts BlueTrack technology, a laser-based system, featuring a blue beam that is 4x larger than a standard laser, and captures a high-contrast image of whatever surface it's on for precise accuracy.
