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.

  • Depending on how deeply hardcoded this misbehavior is, internal user patches or external 3rd-party software may be able to fix it.
  • After id Software’s commercial hit of Doom, which did not support vertical aiming, competitor Bungie’s Marathon became the first first-person shooter to support using the mouse to aim up and down.
  • Players could achieve this by holding down a key for strafing while continuously aiming the mouse toward the opponent.
  • This driver provides the state of the buttons and the distance the mouse has moved in units that its documentation calls “mickeys”.
  • 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.

Mechanical Mice

They inherently offer 3D coordinates along with pressure, size, tilt, angle, mask, and even an image bitmap to see and recognize the input point/object on the screen. A mouse typically controls the motion of a pointer in two dimensions in a graphical user interface . The mouse turns movements of the hand backward and forward, left and right into equivalent electronic signals that in turn are used to move the pointer. The trackball used four disks to pick up motion, two each for the X and Y directions.

Weighting 465 g, the device with a total height of about 7 cm came in a c. 12 cm diameter hemispherical injection-molded thermoplastic casing featuring one central push button. Since around the late 1990s, the three-button scrollmouse has become the de facto standard. Users most commonly employ the second button to invoke a contextual menu in the computer’s software user interface, which contains options specifically tailored to the interface element over which the mouse cursor currently sits.

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.

However, speed can also refer to the ratio between how many pixels the cursor moves on the screen and how far the mouse moves on the mouse pad, which may be expressed as pixels per mickey, pixels per inch, or pixels per centimeter. Windows also has full support for multiple input/mouse configurations for multi-user environments. While primarily a motion-sensing device , Wii Remote can also detect its spatial position by comparing the distance and position of the lights from the IR emitter using its integrated IR camera . The obvious drawback to this approach is that it can only produce spatial coordinates while its camera can see the sensor bar. More accurate consumer devices have since been released, including the PlayStation Move, the Razer Hydra, and the controllers part of the HTC Vive virtual reality system. All of these devices can accurately detect position and orientation in 3D space regardless of angle relative to the sensor station.

Many shooting genre players prefer a mouse over a gamepad analog stick because the wide range of motion offered by a mouse allows for faster and more varied control. Although an analog stick allows the player more granular control, it is poor for certain movements, as the player’s input is relayed based on a vector of both the stick’s direction and magnitude. Thus, a small but fast movement (known as “flick-shotting”) using a gamepad requires the player to quickly move the stick from its rest position to the edge and back again in quick succession, a difficult maneuver. The effect of this is that a mouse is well suited not only to small, precise movements but also to large, quick movements and immediate, responsive movements; all of which are important in shooter gaming. This advantage also extends in varying degrees to similar game styles such as third-person shooters. Nearly all mice now have an integrated input primarily intended for scrolling on top, usually a single-axis digital wheel or rocker switch which can also be depressed to act as a third button.
