Mousepad
A mousepad (or mouse mat) is a surface for enhancing the movement of a computer mouse.
Types
Two types of mousepad exist - textured ones for improving the tracking of a ball mouse, and shiny, sometimes gridded metallic ones for older optical mice. Newer optical mice do not require mousepads. Specialised pads also exist for where extra accuracy is needed.
Designs
Originally mousepads were available in a simple rectangular shape. In recent years, though, they have been available in many shapes and designs. Ergonomic designs are available with built-in wrist rests. Companies often give away mousepads for promotional reasons, and computer manufacturers often include a mousepad with their logo on it, usually with technical support information. Many artists have published their work on a mousepad. Sevaral compaines make special mouse pads for gamers. These include ratpadz gs and the func surface 1030. These mouse pads are hard, so the mouse glides over it easily, and large, so the mouse doesn't have to be picked up as much allowing more movement during a game.
Materials
Typically, modern mousepads are based on plastic or foam. However, other types (including fabric and those manufactured from recycled rubber tires) are available.
