A mouse is an input device for a computer. It allows you to move a cursor or pointer on a computer screen or make selections. Computer mice can be corded or wireless. They work with a variety of applications and come in different shapes and sizes. Choosing the right mouse depends on how much you want to spend, what applications you mostly use it for and what your ergonomic needs are.
Types of Mice
There are three types of mice: mechanical, optical and laser. The original mouse was mechanical. It had a rubber ball that rolled along some surface, such as a mouse pad, while mechanical sensors detected the ball’s movements inside the mouse’s cover. A wire connecting it to a computer made the mouse resemble the animal with the same name. Mechanical mice are considered obsolete, but are very cheap alternatives to other mice.
An optical mouse is more sensitive than a mechanical mouse and with no moving parts it requires little cleaning. Optical mice work without the old roller ball. Instead, a LED (light emitting diode) produces light underneath the mouse and the light reflected back allows the tracking of movements. A disadvantage to this type of mouse is that it does not work well on reflective surfaces.
Laser mice are considered slightly more accurate than optical mice. A laser mouse uses a laser to track movement instead of a LED. Unlike an optical mouse it can work on glossy surfaces, but has trouble when it moves on glass or mirrors.
Cordless or Wireless
Besides choosing a mouse based on how it operates, you can decide on getting a corded or wireless mouse. Consumersearch.com reviews the advantages and disadvantages of having a corded mouse. A corded mouse connects to a computer’s USB (universal serial bus) port or to a PS/2 port in older models. Wireless mice use radio-frequency or Bluetooth technology to connect to computers without cords. Corded mice are cheaper and also do not require batteries like their wireless counterparts. Wireless mice offer more freedom of movement since they work without attachments.
Other Factors and Alternatives to Typical Mice
Computer mice can be designed to fit certain ergonomic needs. They go beyond the basic design of a mouse to offer a more natural fit for the hand. Left-handed users can purchase mice designed specifically for them, like Logitech’s MX610 Left-Hand laser mouse.
Trackballs exist where the ball rests on the top of the mouse and is moved by hand, not rolled on a particular surface. An example of this is Logitech's Trackman Wheel. For those who don't like or can't use their hands foot mice are available. Some digital pens may also be used as computer mice.
