Ebony guy has to prove he is really gay to get scholarship. 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. Another type of mechanical mouse, the "analog mouse" now generally regarded as obsolete , uses potentiometers rather than encoder wheels, and is typically designed to be plug compatible with an analog joystick.

The "Color Mouse", originally marketed by RadioShack for their Color Computer but also usable on MS-DOS machines equipped with analog joystick ports, provided the software accepted joystick input was the best-known example.

Early optical mice relied 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.

Laser diodes provide good resolution and precision, improving performance on opaque specular surfaces. Later, more surface-independent optical mice use an optoelectronic sensor essentially, a tiny low-resolution video camera to take successive images of the surface on which the mouse operates.

Battery powered, wireless optical mice flash the LED intermittently to save power, and only glow steadily when movement is detected.

Often called "air mice" since they do not require a surface to operate, inertial mice use a tuning fork or other accelerometer US Patent [50] to detect rotary movement for every axis supported.

The most common models manufactured by Logitech and Gyration work using 2 degrees of rotational freedom and are insensitive to spatial translation.

The user requires only small wrist rotations to move the cursor, reducing user fatigue or " gorilla arm ". Usually cordless, they often have a switch to deactivate the movement circuitry between use, allowing the user freedom of movement without affecting the cursor position.

A patent for an inertial mouse claims that such mice consume less power than optically based mice, and offer increased sensitivity, reduced weight and increased ease-of-use.

Also known as bats, [52] flying mice, or wands, [53] these devices generally function through ultrasound and provide at least three degrees of freedom.

Probably the best known example would be 3Dconnexion " Logitech 's SpaceMouse" from the early s. In the late s Kantek introduced the 3D RingMouse.

This wireless mouse was worn on a ring around a finger, which enabled the thumb to access three buttons. The mouse was tracked in three dimensions by a base station.

One example of a s consumer 3D pointing device is the Wii Remote. While primarily a motion-sensing device that is, it can determine its orientation and direction of movement , 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 since the nunchuk accessory lacks a camera, it can only tell its current heading and orientation.

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.

A mouse-related controller called the SpaceBall [55] has a ball placed above the work surface that can easily be gripped. With spring-loaded centering, it sends both translational as well as angular displacements on all six axes, in both directions for each.

This new concept of a true six degree-of-freedom input device uses a ball to rotate in 3 axes without any limitations. Logitech spacemouse 3D.

Silicon Graphics SpaceBall model , allowing manipulation of objects with six degrees of freedom. In , Logitech introduced a "tactile mouse" that contained a small actuator to make the mouse vibrate.

Such a mouse can augment user-interfaces with haptic feedback, such as giving feedback when crossing a window boundary.

To surf by touch requires the user to be able to feel depth or hardness; this ability was realized with the first electrorheological tactile mice [57] but never marketed.

Tablet digitizers are sometimes used with accessories called pucks, devices which rely on absolute positioning, but can be configured for sufficiently mouse-like relative tracking that they are sometimes marketed as mice.

As the name suggests, this type of mouse is intended to provide optimum comfort and avoid injuries such as carpal tunnel syndrome , arthritis and other repetitive strain injuries.

It is designed to fit natural hand position and movements, to reduce discomfort. When holding a typical mouse, ulna and radius bones on the arm are crossed.

Some designs attempt to place the palm more vertically, so the bones take more natural parallel position. A mouse may be angled from the thumb downward to the opposite side — this is known to reduce wrist pronation.

Another solution is a pointing bar device. The so-called roller bar mouse is positioned snugly in front of the keyboard, thus allowing bi-manual accessibility.

These mice are specifically designed for use in computer games. They typically employ a wider array of controls and buttons and have designs that differ radically from traditional mice.

Some mice may include several different rests with their products to ensure comfort for a wider range of target consumers. Cordless mice instead transmit data via infrared radiation see IrDA or radio including Bluetooth , although many such cordless interfaces are themselves connected through the aforementioned wired serial buses.

While the electrical interface and the format of the data transmitted by commonly available mice is currently standardized on USB, in the past it varied between different manufacturers.

Mouse use in DOS applications became more common after the introduction of the Microsoft Mouse , largely because Microsoft provided an open standard for communication between applications and mouse driver software.

Thus, any application written to use the Microsoft standard could use a mouse with a driver that implements the same API, even if the mouse hardware itself was incompatible with Microsoft's.

This driver provides the state of the buttons and the distance the mouse has moved in units that its documentation calls " mickeys ", [76] as does the Allegro library.

In the s, the Xerox Alto mouse, and in the s the Xerox optical mouse , used a quadrature-encoded X and Y interface. This two-bit encoding per dimension had the property that only one bit of the two would change at a time, like a Gray code or Johnson counter , so that the transitions would not be misinterpreted when asynchronously sampled.

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.

The mouse was a simple optomechanical device, and the decoding circuitry was all in the main computer. The DE-9 connectors were designed to be electrically compatible with the joysticks popular on numerous 8-bit systems, such as the Commodore 64 and the Atari Although the ports could be used for both purposes, the signals must be interpreted differently.

As a result, plugging a mouse into a joystick port causes the "joystick" to continuously move in some direction, even if the mouse stays still, whereas plugging a joystick into a mouse port causes the "mouse" to only be able to move a single pixel in each direction.

Because the IBM PC did not have a quadrature decoder built in, early PC mice used the RS C serial port to communicate encoded mouse movements, as well as provide power to the mouse's circuits.

The Mouse Systems Corporation version used a five-byte protocol and supported three buttons. The Microsoft version used a three-byte protocol and supported two buttons.

Due to the incompatibility between the two protocols, some manufacturers sold serial mice with a mode switch: "PC" for MSC mode, "MS" for Microsoft mode.

In Apple first implemented the Apple Desktop Bus allowing the daisy-chaining linking together in series, ie. After the host sends a special command sequence, it switches to an extended format in which a fourth byte carries information about wheel movements.

The IntelliMouse Explorer works analogously, with the difference that its 4-byte packets also allow for two additional buttons for a total of five.

Mouse vendors also use other extended formats, often without providing public documentation. In the late s, Logitech created ultrasound based tracking which gave 3D input to a few millimeters accuracy, which worked well as an input device but failed as a profitable product.

The industry-standard USB Universal Serial Bus protocol and its connector have become widely used for mice; it is among the most popular types.

Some of these can be stored inside the mouse for safe transport while not in use, while other, newer mice use newer " nano " receivers, designed to be small enough to remain plugged into a laptop during transport, while still being large enough to easily remove.

The Logitech Metaphor, the first wireless mouse Some systems allow two or more mice to be used at once as input devices.

Lates era home computers such as the Amiga used this to allow computer games with two players interacting on the same computer Lemmings and The Settlers for example.

The same idea is sometimes used in collaborative software , e. 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.

Multiple mice are often used in multi-user gaming in addition to specially designed devices that provide several input interfaces. Starting with Windows XP, Microsoft introduced an SDK for developing applications that allow multiple input devices to be used at the same time with independent cursors and independent input points.

However, it no longer appears to be available. The new input points provide traditional mouse input; however, they were designed with other input technologies like touch and image in mind.

As of , Linux distributions and other operating systems that use X. However, currently no window managers support Multi-Pointer X leaving it relegated to custom software usage.

There have also been propositions of having a single operator use two mice simultaneously as a more sophisticated means of controlling various graphics and multimedia applications.

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.

Since around the late s, 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.

By default, the primary mouse button sits located on the left-hand side of the mouse, for the benefit of right-handed users; left-handed users can usually reverse this configuration via software.

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.

Though less common, many mice instead have two-axis inputs such as a tiltable wheel, trackball , or touchpad.

Those with a trackball may be designed to stay stationary, using the trackball instead of moving the mouse. Mickeys per second is a unit of measurement for the speed and movement direction of a computer mouse, [76] where direction is often expressed as "horizontal" versus "vertical" mickey count.

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.

In early mice, this specification was called pulses per inch ppi. If the default mouse-tracking condition involves moving the cursor by one screen-pixel or dot on-screen per reported step, then the CPI does equate to DPI: dots of cursor motion per inch of mouse motion.

However, software can adjust the mouse sensitivity, making the cursor move faster or slower than its CPI. Current [update] software can change the speed of the cursor dynamically, taking into account the mouse's absolute speed and the movement from the last stop-point.

In most software, an example being the Windows platforms, this setting is named "speed," referring to "cursor precision".

However, some operating systems name this setting "acceleration", the typical Apple OS designation. This term is incorrect.

Mouse acceleration in most mouse software refers to the change in speed of the cursor over time while the mouse movement is constant.

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 or multiplied by a rate factor, typically less than 1.

The cursor will move slowly on the screen, with good precision. 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. Operating systems sometimes apply acceleration, referred to as " ballistics ", to the motion reported by the mouse.

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.

These doublings applied separately in the X and Y directions, resulting in very nonlinear response. Engelbart's original mouse did not require a mousepad; [96] 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.

The mousepad, the most common mouse accessory, appears most commonly in conjunction with mechanical mice, because to roll smoothly the ball requires more friction than common desk surfaces usually provide.

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.

Mouse Systems. Whether to use a hard or soft mousepad with an optical mouse is largely a matter of personal preference. One exception occurs when the desk surface creates problems for the optical or laser tracking, for example, a transparent or reflective surface, such as glass.

Some mice also come with small "pads" attached to the bottom surface, also called mouse feet or mouse skates, that help the user slide the mouse smoothly across surfaces.

However, none of these products achieved large-scale success. Only with the release of the Apple Macintosh in did the mouse see widespread use.

The Macintosh design, [99] commercially successful and technically influential, led many other vendors to begin producing mice or including them with their other computer products by , Atari ST , Amiga , Windows 1.

The widespread adoption of graphical user interfaces in the software of the s and s made mice all but indispensable for controlling computers.

In November , Logitech built their billionth mouse. 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 or turning left and right, and the Y-axis for looking up and down; the keyboard is used for movement and supplemental inputs.

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.

In addition the stick also has a finite magnitude; if the player is currently using the stick to move at a non-zero velocity their ability to increase the rate of movement of the camera is further limited based on the position their displaced stick was already at before executing the 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.

Some incorrectly ported games or game engines have acceleration and interpolation curves which unintentionally produce excessive, irregular, or even negative acceleration when used with a mouse instead of their native platform's non-mouse default input device.

Depending on how deeply hardcoded this misbehavior is, internal user patches or external 3rd-party software may be able to fix it. Due to their similarity to the WIMP desktop metaphor interface for which mice were originally designed, and to their own tabletop game origins, computer strategy games are most commonly played with mice.

In particular, real-time strategy and MOBA games usually require the use of a mouse. The left button usually controls primary fire. If the game supports multiple fire modes, the right button often provides secondary fire from the selected weapon.

Games with only a single fire mode will generally map secondary fire to ADS. 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.

Players can use a scroll wheel for changing weapons or for controlling scope-zoom magnification, in older games.

On most first person shooter games, programming may also assign more functions to additional buttons on mice with more than three controls.

A keyboard usually controls movement for example, WASD for moving forward, left, backward and right, respectively and other functions such as changing posture.

Since the mouse serves for aiming, a mouse that tracks movement accurately and with less lag latency will give a player an advantage over players with less accurate or slower mice.

In some cases the right mouse button may be used to move the player forward, either in lieu of, or in conjunction with the typical WASD configuration.

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 towards the opponent.

Games using mice for input are so popular that many manufacturers make mice specifically for gaming.

Such mice may feature adjustable weights, high-resolution optical or laser components, additional buttons, ergonomic shape, and other features such as adjustable CPI.

Mouse Bungees are typically used with gaming mice because it eliminates the annoyance of the cable. Many games, such as first- or third-person shooters, have a setting named "invert mouse" or similar not to be confused with "button inversion", sometimes performed by left-handed users which allows the user to look downward by moving the mouse forward and upward by moving the mouse backward the opposite of non-inverted movement.

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.

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.

The "invert" feature actually made the mouse behave in a manner that users now [update] regard as non-inverted by default, moving mouse forward resulted in looking down.

Soon after, id Software released Quake , which introduced the invert feature as users now [update] know it. In , the VTech Socrates educational video game console featured a wireless mouse with an attached mouse pad as an optional controller used for some games.

In the early s, the Super Nintendo Entertainment System video game system featured a mouse in addition to its controllers.

The Mario Paint game in particular used the mouse's capabilities [] as did its successor on the N Nintendo's Wii also had this added on in a later software update, retained on the Wii U.

In November , Logitech built their billionth mouse. 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 or turning left and right, and the Y-axis for looking up and down; the keyboard is used for movement and supplemental inputs.

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.

In addition the stick also has a finite magnitude; if the player is currently using the stick to move at a non-zero velocity their ability to increase the rate of movement of the camera is further limited based on the position their displaced stick was already at before executing the 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.

Some incorrectly ported games or game engines have acceleration and interpolation curves which unintentionally produce excessive, irregular, or even negative acceleration when used with a mouse instead of their native platform's non-mouse default input device.

Depending on how deeply hardcoded this misbehavior is, internal user patches or external 3rd-party software may be able to fix it. Due to their similarity to the WIMP desktop metaphor interface for which mice were originally designed, and to their own tabletop game origins, computer strategy games are most commonly played with mice.

In particular, real-time strategy and MOBA games usually require the use of a mouse. The left button usually controls primary fire.

If the game supports multiple fire modes, the right button often provides secondary fire from the selected weapon. Games with only a single fire mode will generally map secondary fire to ADS.

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.

Players can use a scroll wheel for changing weapons or for controlling scope-zoom magnification, in older games. On most first person shooter games, programming may also assign more functions to additional buttons on mice with more than three controls.

A keyboard usually controls movement for example, WASD for moving forward, left, backward and right, respectively and other functions such as changing posture.

Since the mouse serves for aiming, a mouse that tracks movement accurately and with less lag latency will give a player an advantage over players with less accurate or slower mice.

In some cases the right mouse button may be used to move the player forward, either in lieu of, or in conjunction with the typical WASD configuration.

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 towards the opponent.

Games using mice for input are so popular that many manufacturers make mice specifically for gaming. Such mice may feature adjustable weights, high-resolution optical or laser components, additional buttons, ergonomic shape, and other features such as adjustable CPI.

Mouse Bungees are typically used with gaming mice because it eliminates the annoyance of the cable. Many games, such as first- or third-person shooters, have a setting named "invert mouse" or similar not to be confused with "button inversion", sometimes performed by left-handed users which allows the user to look downward by moving the mouse forward and upward by moving the mouse backward the opposite of non-inverted movement.

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.

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.

The "invert" feature actually made the mouse behave in a manner that users now [update] regard as non-inverted by default, moving mouse forward resulted in looking down.

Soon after, id Software released Quake , which introduced the invert feature as users now [update] know it. In , the VTech Socrates educational video game console featured a wireless mouse with an attached mouse pad as an optional controller used for some games.

In the early s, the Super Nintendo Entertainment System video game system featured a mouse in addition to its controllers.

The Mario Paint game in particular used the mouse's capabilities [] as did its successor on the N Nintendo's Wii also had this added on in a later software update, retained on the Wii U.
