Mouse

A hardware device used to get input from the user, usually to interact with the GUI.

A mouse can be either wired or wireless. Mice usually are connected via USB ports. Wireless mice use an internal battery to power RF signal receptors that are tied to the computer they're linked to or to a USB port receiver plugged into the computer.

Features & Considerations (Raw Lesson Content)

• Because optical mice use light rays to detect motion, they don't work on some surfaces.
• Some mice have internal motion sensors, allowing them to detect movements while in the air. This particular device can attach to a user's head and move the cursor when the head moves.
• You can select mice with additional buttons or a scroll wheel to add functionality.
• High-end gaming mice use a rating of dots per inch (DPI). The rating denotes how many steps (cursor movements) are counted in a single inch.
