Optical computer mouse
A mouse is a pointing device, typically for use with visual display systems in which a transducer converts translational motion of a housing into a position signal for controlling the movement of a cursor associated with a visual display system. Generally, in a mouse used as a main input devices of a computer, a ball mouse having a ball has problems in that sliding occurs due to dust and a user's movement may not be exactly transferred to a display screen of a computer system when the user moves the ball mouse. It is difficult to use the ball mouse for a long time due to abrasion of the ball and parts in contact with the ball. An optical mouse device is an improvement over the conventional mechanical mouse device. An optical mouse is designed to detect movement of an image carried in light reflected from a mouse pad having the image thereon and received therein, thereby causing a cursor on an associated computer display screen to be moved in accordance with the movement of the mouse, and to enable several functional signals to be inputted to a computer system by clicking of buttons equipped thereon, separately from a computer keyboard unit. An optical computer mouse generally comprises an image sensor for sensing an image of a motion and outputting the resulting image signal, an A/D converter for converting the image signal from the image sensor into digital data, an image processor for performing a signal processing operation for the digital data from the A/D converter to detect the motion therefrom, and a controller for providing data corresponding to the detected motion to a host computer. An optical mouse is adapted to cause a cursor on a display screen to be moved, by optically detecting its own motion, converting the detected value to an electrical signal, and sending the signal to a computer. An optical mouse has several advantages such as its precise detection of a movement of user's hand and its smooth movement, compared with a conventional ball mouse.
