Many games provide players with the option of mapping their own choice of a key or button to a certain control. An early technique of players, circle strafing, saw a player continuously strafing while aiming and shooting at an opponent by walking in circle around the opponent with the opponent at the center of the circle. Players could achieve this by holding down a key for strafing while continuously aiming the mouse toward the opponent.

Bill English, builder of Engelbart’s original mouse, created a ball mouse in 1972 while working for Xerox PARC. The plural for a computer mouse is either “mice” or “mouses” according to most dictionaries, with “mice” being more common. The first recorded plural usage is “mice”; the online Oxford Dictionaries cites a 1984 use, and earlier uses include J.

  • Another type of mechanical mouse, the “analog mouse” , uses potentiometers rather than encoder wheels, and is typically designed to be plug compatible with an analog joystick.
  • The popularity of wireless mice without cords makes the resemblance less obvious.
  • A contactless sensor design uses a magnetic sensor array for sensing three aches translation and two optical mouse sensors for three aches rotation.

With spring-loaded centering, it sends both translational as well as angular displacements on all six axes, in both directions for each. In November 2010 a German Company called Axsotic introduced a new concept of 3D mouse called 3D Spheric Mouse. This new concept of a true six degree-of-freedom input device uses a ball to rotate in 3 axes and an elastic polymer anchored tetrahedron inspired suspension for translating the ball without any limitations. A contactless sensor design uses a magnetic sensor array for sensing three aches translation and two optical mouse sensors for three aches rotation. The special tetrahedron suspension allows a user to rotate the ball with the fingers while input translations with the hand-wrist motion.

The popularity of wireless mice without cords makes the resemblance less obvious. Signals XA and XB in quadrature convey X-direction motion, while YA and YB convey Y-dimension motion; here the pointer is shown drawing a small curve. Inspired by PARC’s Alto, the Lilith, a computer which had been developed by a team around Niklaus Wirth at ETH Zürich between 1978 and 1980, provided a mouse as well. “Connect a Bluetooth device that does not have or require a transceiver”. Silicon Graphics SpaceBall model 1003 , allowing manipulation of objects with six degrees of freedom. The third marketed version of an integrated mouse shipped as a part of a computer and intended for personal computer navigation came with the Xerox 8010 Star in 1981.

This wireless mouse was worn on a ring around a finger, which enabled the thumb to access three buttons. Despite a certain appeal, it was finally discontinued because it did not provide sufficient resolution. One roller detects the forward-backward motion of the mouse and the other the left-right motion. Opposite the two rollers is a third one 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.

Use In Games

To surf the internet by touch-enabled mouse was first developed in 1996 and first implemented commercially by the Wingman Force Feedback Mouse. It requires the user to be able to feel depth or hardness; this ability was realized with the first electrorheological tactile mice but never marketed. When mice have more than one button, the software may assign different functions to each button. Often, the primary (leftmost in a right-handed configuration) button on the mouse will select items, and the secondary (rightmost in a right-handed) button will bring up a menu of alternative actions applicable to that item. Users can also employ mice gesturally, meaning that a stylized motion of the mouse cursor itself, called a “gesture”, can issue a command or map to a specific action. For example, in a drawing program, moving the mouse in a rapid “x” motion over a shape might delete the shape.

For simple software, when the mouse starts to move, the software will count the number of “counts” or “mickeys” received from the mouse and will move the cursor across the screen by that number of pixels . When the movement of the mouse passes the value set for some threshold, the software will start to move the cursor faster, with a greater rate factor. Usually, the user can set the value of the second rate factor by changing the “acceleration” setting. Mickeys per second is a unit of measurement for the speed and movement direction of a computer mouse, where direction is often expressed as “horizontal” versus “vertical” mickey count.
