Ball or roller mouse A ball or roller mouse uses a single ball that can rotate in any direction. It has perpendicular chopper wheels inside its body, which uses chopped beams of light to detect ball motion. It must be dragged over a mouse pad or a smooth surface to create a smooth motion. Trackball mouse A trackball mouse is an upside-down roller mouse housed in a socket with a protruding ball on the side. It also uses light sensors to detect ball motion. The ball is rolled using the thumb, fingers, or palm. Optical mouse An optical mouse uses photodiodes and a light-emitting diode (LED)to detect movement from its underlying surface. It is more durable than the ball mouse and covers more surface area. Laser mouse A laser mouse is a type of optical mouse that infrared laser beams instead of LEDs. It has a higher resolution than a regular mouse and is 20 times more sensitive to the surface. Wireless mouse A wireless mouse uses Bluetooth, infrared, or radio frequency (RF) to connect to the computer. It is usually powered by batteries. It allows more freedom of movement because it is not restrained by a cable. Gaming mouse A gaming mouse is a specialized mouse intended for PC gamers. It is designed with reduced latency, improved responsiveness, and a more comfortable grip. |
