It is an important creation because it allows a user to simply point to objects on the screen without using the keyboard. It plays an important role in design programs in which the user can draw on the screen by moving the mouse like he would move a pen, pencil, or paintbrush to draw. Mechanical sensors within the mouse detect the direction the ball is rolling and move the screen pointer accordingly. Same as a mechanical mouse, but uses optical sensors to detect motion of the ball. You must move the mouse along a special mat with a grid so that the optical mechanism has a frame of reference.
Optical mice have no mechanical moving parts.
They respond more quickly and precisely than mechanical and optomechanical mice, but they are also more expensive. The use of computers to present text, graphics, video, animation, and sound in an integrated way. Long touted as the future revolution in computing, multimedia applications were, until the mid-90s, uncommon due to the expensive hardware required. With recent increases in performance and decreases in price, however, multimedia is finally finding its way into the mainstream of personal computer applications. To date, most multimedia titles have been games or preference works, but we can expect other types of applications to use multimedia in the future.
