Moving the mouse turns the ball. X and Y rollers grip the ball and transfer movement.

Optical encoding disks include light holes. Infrared LEDs shine through the disks. Sensors gather light pulses to convert to X and Y vectors. The German company Telefunken published on their early ball mouse on 2 October It came as part of the hardware package of the Xerox Alto computer.

Perpendicular chopper wheels housed inside the mouse's body chopped beams of light on the way to light sensors, thus detecting in their turn the motion of the ball. This variant of the mouse resembled an inverted trackball and became the predominant form used with personal Addison Optical Scroll 2 button Mini Mouse throughout the s and s. The Xerox PARC group also settled on the modern technique of using both hands to type on a full-size keyboard and grabbing the mouse when required.

Mechanical mouse, shown with the top cover removed. The scroll wheel is gray, to the right of the ball.

The ball mouse has two freely rotating rollers. These are located 90 degrees apart.

One roller detects the forward—backward motion of the mouse and other the left—right motion. Opposite the two rollers is a third one white, in the photo, at 45 degrees that is spring-loaded to push the ball against the other two rollers.

Each roller is on the same shaft as an encoder wheel that has slotted edges; the slots interrupt infrared light beams to generate electrical pulses that represent wheel movement. Each wheel's disc has a pair of light beams, located so that a given beam becomes interrupted or again starts to pass light freely when the other beam of the pair is about halfway between changes.

Simple logic circuits interpret the relative timing to indicate which direction the wheel is rotating. This incremental rotary encoder scheme is sometimes called quadrature encoding of the wheel rotation, as the two optical sensors produce signals that are in approximately quadrature phase.

Computer mouse - Wikipedia

The mouse sends these signals to the computer system via the mouse cable, directly as logic signals in very old mice such as Addison Optical Scroll 2 button Mini Mouse Xerox mice, and via a data-formatting IC in modern mice. The driver software in the system converts the signals into motion of the mouse cursor along X and Y axes on the computer screen.

The weight of the ball, given an appropriate working surface under the mouse, provides a reliable grip so the mouse's movement is transmitted accurately.

Key Tronic later produced a similar product. The "Color Mouse", originally marketed by RadioShack for their Color Computer but also usable on Addison Optical Scroll 2 button Mini Mouse machines equipped with analog joystick ports, provided the software accepted joystick input was the best-known example. Optical and laser mice[ edit ] The underside of an optical mouse. Main article: Optical mouse Optical mice rely entirely on one or more light-emitting diodes LEDs and an imaging array of photodiodes to detect movement relative to the underlying surface, eschewing the internal moving parts a mechanical mouse uses in addition to its optics.

A laser mouse is an optical mouse that uses coherent laser light. The earliest optical mice detected movement on pre-printed mousepad surfaces, whereas the modern LED optical mouse works on most opaque diffuse surfaces; it is usually unable to detect movement on specular surfaces like polished stone.

Oh no, there's been an error

Laser diodes are also used for better resolution and precision, improving performance on opaque specular surfaces. Battery powered, wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected.

Inertial and gyroscopic mice[ edit ] Often called "air mice" since they do not require a surface to operate, inertial mice use a tuning fork or other accelerometer US Patent [49] to detect rotary movement for every axis supported.
