“Logitech is pushing out a 25,600 DPI software update to several gaming mice

In addition to moving a cursor, computer mice have one or more buttons to allow operations such as the selection of a menu item on a display. Mice often also feature other elements, such as touch surfaces and scroll wheels, which enable additional control and dimensional input. A computer mouse is a hand-held pointing device that detects two-dimensional motion relative to a surface. This motion is typically translated into the motion of a pointer on a display, which allows a smooth control of the graphical user interface of a computer. Most optical and laser mice do not require a pad, the notable exception being early optical mice which relied on a grid on the pad to detect movement (e.g. Mouse Systems). Whether to use a hard or soft mousepad with an optical mouse is largely a matter of personal preference.

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.

Mouse buttons are microswitches which can be pressed to select or interact with an element of a graphical user interface, producing a distinctive clicking sound. Windows XP Service Pack 2 introduced a Bluetooth stack, allowing Bluetooth mice to be used without any USB receivers. Windows Vista added native support for horizontal scrolling and standardized wheel movement granularity for finer scrolling. The earliest mass-market mice, such as on the original Macintosh, Amiga, and Atari ST mice used a D-subminiature 9-pin connector to send the quadrature-encoded X and Y axis signals directly, plus one pin per mouse button.

Late-1980s era home computers such as the Amiga used this to allow computer games with two players interacting on the same computer . The same idea is sometimes used in collaborative software, e.g. to simulate a whiteboard that multiple users can draw on without passing a single mouse around. Microsoft Windows, since Windows 98, has supported multiple simultaneous pointing devices. Because Windows only provides a single screen cursor, using more than one device at the same time requires cooperation of users or applications designed for multiple input devices. This control system resembles that of aircraft control sticks, where pulling back causes pitch up and pushing forward causes pitch down; computer joysticks also typically emulate this control-configuration. The ball mouse replaced the external wheels with a single ball that could rotate in any direction.

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.

  • In some games, the right button may also invoke accessories for a particular weapon, such as allowing access to the scope of a sniper rifle or allowing the mounting of a bayonet or silencer.
  • For example, versions of Windows prior to Windows XP doubled reported values above a configurable threshold, and then optionally doubled them again above a second configurable threshold.
  • Battery powered, wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected.
  • Engelbart never received any royalties for it, as his employer SRI held the patent, which expired before the mouse became widely used in personal computers.
  • As noted above, this “mouse” was first mentioned in print in a July 1965 report, on which English was the lead author.

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.

The Mario Paint game in particular used the mouse’s capabilities as did its successor on the N64. Sega released official mice for their Genesis/Mega Drive, Saturn and Dreamcast consoles. Sony released an official mouse product for the PlayStation console, included one along with the Linux for PlayStation 2 kit, as well as allowing owners to use virtually any USB mouse with the PS2, PS3, and PS4. Nintendo’s Wii also had this added on in a later software update, retained on the Wii U.

FPSs naturally lend themselves to separate and simultaneous control of the player’s movement and aim, and on computers this has traditionally been achieved with a combination of keyboard and mouse. Players use the X-axis of the mouse for looking left and right, and the Y-axis for looking up and down; the keyboard is used for movement and supplemental inputs. Engelbart’s original mouse did not require a mousepad; the mouse had two large wheels which could roll on virtually any surface. However, most subsequent mechanical mice starting with the steel roller ball mouse have required a mousepad for optimal performance.
