A computer mouse (singular mice or mouses), is a hand-held portable pointing device that senses two-dimensional (non-rotational) movement relative to a surface such as a computer monitor or keyboard. This movement is usually translated into a tactile (or sometimes non-tactile) signal, which enables a user to control the graphical user interface of their computer. A computer mouse has a sensor in the center that translates the user's finger's position into a signal that enables it to detect the surface against which it is pointing.
A computer mouse is designed to be used in conjunction with other input devices to give a more intuitive user experience while operating a computer. The primary functions of the computer mouse are to provide a pointing device to manipulate and view images and text on a screen; to detect the presence of the user's hands on the surface to control key commands; and to provide an interface with a stylus-like stylus for input of information or tasks, such as for dictation or handwriting recognition. Although they are primarily used to manipulate images, they can also be used for gaming, using the mouse for navigation and interactivity. The design of today's modern computer mouse is much different from the early versions, which were largely hand-held devices.
While mouse technology was first developed in the 1970's, it was not until the mid-1980's that it really took off as a popular desktop device. The first major commercial use of this type of mouse was in the Xerox Corporation's PARC project. This group was studying the use of multi-touch input devices, a technology that is now a common component of computer systems. Another early use of the computer mouse was in the Microsoft Windows program.
Today, there are many different types of computer mice to choose from. The most popular variety of mice for arthritic patients are the wireless USB or Bluetooth wireless model. The wireless type of mouse is easier to use and provides greater comfort than traditional mouse models, but it does have limitations for medical reasons.
Some other types of computer mice for arthritis are wired, such as wireless USB mice, but are more convenient for medical reasons, like a wireless Bluetooth mouse. A wireless infrared computer mouse can also be a viable option. For people who experience pain due to arthritis, a specialized computer mouse will allow them to easily navigate their computer environment, and eliminate the discomfort associated with traditional mice.
There are many other types of mouse available for patients with the medical conditions. One type of mouse for arthritis is the optical, wireless mouse, which enables the patient to move around their computer without having to deal with wires. Wires at all, and the optical mouse are also great for people who have a certain form of retinal disease. The infrared computer mouse is great for people who use computers that are located near their work environment, like at a workstation.
