The special tetrahedron suspension allows a user to rotate the ball with the fingers while input translations with the hand-wrist motion. Logitech spacemouse 3D. Silicon Graphics SpaceBall model , allowing manipulation of objects with six degrees of freedom.

In , Logitech introduced a "tactile mouse" known as the "iFeel Mouse" developed by Immersion Corporation that contained a small actuator to enable the mouse to generate simulated physical sensations. To surf the internet by touch-enabled mouse was first developed in [76] and first implemented commercially by the Wingman Force Feedback Mouse.

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, the 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.

The additional buttons can often be used for changing the sensitivity of the mouse [84] or they can be assigned programmed to macros i. 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 ". 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 of up to 16 devices, including mice and other devices on the same bus with no configuration whatsoever. Featuring only a single data pin, the bus used a purely polled approach to device communications and survived as the standard on mainstream models including a number of non-Apple workstations until when Apple's iMac line of computers joined the industry-wide switch to using USB. 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.

Cordless or wireless mice transmit data via radio. Many mice that use a USB receiver have a storage compartment for it inside the mouse. Some "nano receivers" are 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, [95] 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.

The computer industry often measures mouse sensitivity in terms of counts per inch CPI , commonly expressed as dots per inch DPI — the number of steps the mouse will report when it moves one inch. 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.

As of , [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; [] 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, [] 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. A sensitivity converter is required in order to translate rotational movements properly. 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 aim down the weapon sights.

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 toward 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.

Mallebrein erroneously remembers them even as 5-bit encoders. However, the description differs between the two sources with 3 bits being inverted. It is therefore possible that the sources are misleading due to incomplete reverse engineering and that both sequences are actually produced by the encoders over a full revolution.

Science and Technology. The Telegraph. Hill" Interview. Interview S2CID Computing: A Concise History. New York: Cambridge University Press. London: Reaktion Books. The Washington Post. WP Company. New York. Bloomberg L. Drive by our gaming mouse roundup for much more detail on the nuances of these mice. Ergonomics-first designs put all of the typical mouse functions into a form factor that places your hand in a neutral position.

Designed to reduce the stresses that can lead to carpal tunnel and repetitive strain injury, ergonomic mice may look unusual and take some getting used to, but they do alleviate some very real problems. Some have a vertical design; others may have one-off sculpts.

Whether you're looking at a specialized ergonomic mouse, or comfort is simply a concern in a more ordinary one, pay attention to the size of your mouse. Make sure that it's not too big or too small for your hand. Weight is also a consideration. Some people prefer a heavier mouse that anchors the hand, while others, especially players of MOBA games, want something light that furnishes little resistance to flicking and clicking.

As a rule of thumb, a heavier mouse requires more effort to move, and even though the difference may not seem like much, over time it can mount. It's not just weight and size that are important. The sculpting of the mouse can also lead to unnecessary strain on or conversely, extra support for your hand and wrist. The most comfortable mice will fit the contour of your hand, rather than having a flat, shallow shape.

Some mice have a thumb rest, providing a resting spot from which the finger can rise as needed to activate controls. See our guide to the best ergonomic mice for more about the nuances of these very variable mice, in addition to a discussion of trackballs.

Computer mice are usually plug-and-play devices, with no additional software to install with the exception of higher-end gaming mice , meaning that plugging in the cable is all the setup you'll need to deal with. Unlike wireless alternatives, a wired device will draw its power over USB, so there are no batteries to worry about.

Wired connections are also preferable for serious gaming or esports use no battery to conk out in the midst of a match , though some high-end wireless mice are indistinguishable, from a response-time perspective, from wired ones. If you want more freedom and less cable clutter on your desk, however, it's hard to beat a wireless mouse. Instead of a wired connection, wireless mice transmit data to your PC through one of two primary means: an RF connection to a USB receiver, or via Bluetooth.

Some mice actually support both, but this is less common than supporting just one. Both have their pros and cons, but if you want to reduce the number of cables on your desk and gain the flexibility to use your mouse unhindered—or even from across the room—wireless is the way to go. Most wireless mice connect to the host computer via the same 2. Know, however, that only in some isolated cases such as with Logitech's Unifying-branded gear can a single USB dongle provide connectivity to more than one device.

That means that unless the vendor specifically notes otherwise, you can't use the same adapter for your wireless mouse and keyboard. Bluetooth options, in contrast, don't monopolize a USB port, and the stable, easy-to-manage connections are ideal for use with mobile devices, such as ultraportables , tablet PCs , and 2-in-1s. In regular use, a Bluetooth connection gives you roughly 30 feet of wireless range, but a Bluetooth mouse may not match the battery life offered by devices with an RF-based USB dongle.

New innovations, such as motion sensors tied to power and connection management, can improve the battery life versus older Bluetooth devices, which maintained an always-on link that drained battery relatively quickly. But you'll want to look at the vendors' estimated battery life on a charge as well as whether the mouse uses an internal battery you recharge, or disposables. Unlike mechanical tracking options of yore, light-based sensors have fewer issues with dust and dirt, and the absence of moving parts means fewer failures.

Optical sensors pair a glowing LED beam—often red, blue, or infrared—with a small photo sensor, tracking movement by repeatedly imaging the surface below the mouse, translating any movement of the mouse into cursor movement. The frequency of this imaging is called the "polling rate," expressed as hertz, or hundreds of instances per second. Because of the imaging sensor used, optical mice are a little less prone to problems caused by lifting the mouse when in use or by mousing on an uneven surface.

Laser mice operate in a similar way, but they use an infrared laser diode instead of an LED. This allows, in some cases, for greater potential sensitivity measured in dots per inch, or dpi and polling rates. The one drawback is that they can be finicky about the surfaces on which they are used.

Premium gaming mice generally use laser sensors, and they tend to work better with opaque mouse-pad surfaces meant for mousing; LEDs can be more forgiving. But this is not an absolute, and frankly, if you're concerned at all about mousing precision, a basic mouse pad will solve all ails. To offer the higher sensitivity of a laser sensor and the versatility of an optical mouse, a few isolated mice use both in tandem.

Most better gaming mice also offer sensitivity adjustment, letting you shift from a precision setting for tight cursor-control circumstances such as lining up a sniper's shot to a broader-sweep one for melee combat and run-and-gun situations, or panning across an RTS world. Below is a rundown of the current top-rated computer mice we've run across in our testing.

Today, mechanical mouse has been replaced in the Optical mouse. These types of mouse have to need cable wire to making connection in computer. In the optical mouse use advance technology such as LED light-emitting diode , optical sensor, and other DSP digital signal processing instead of the rubber ball mechanical mouse.

In the optical mouse , detect the movement by the sensors when reflected light. No need the cleaning to optical mouse because it has not contained any moving components. Cordless mouse is also known as wireless mouse, and these types of mouse are connected with computers with the help of different unique technologies such as Bluetooth, RF, or infrared radio waves. In the computer, has to contain USB device that receives the spreaded signals from the wireless mice.

Trace ball mouse is an input pointing device. It contains ball upside of the socket, and detecting the movement of ball with the help of sensors while rolling the ball with fingers, palm or thumbs of human hand for moving cursor on the computer screen. Stylus mouse is another type of input device. This stylus mouse use for the high volume graphic and drawing purpose, and it looks like as pen. The graphic and drawing tasks are performed on the special pad by artistic.

A 3D mouse is special input pointing device for creating movement in virtual 3D and 2D environment. This 3D mouse is not use for normal task, mainly designed for the gaming controller to create the game console. These types of mouse mostly use for showing the presentation on the screen, but if, you are not able to use proper smooth surface for rolling the mouse then that situation using accelerometer for converting the motion your hand with the using air into movements of on screen pointer.

In laser mouse , implements the laser light for detecting mouse directions. Laser mouse do not contain any moving components inside mouse, its accuracy is good compare to other optical mouse because these types of mouse provide 20X greater sensitivity and precision, due to this feature those mouse use for gaming, graphic, and engineering designs, where to require pinpoint accuracy. A foot mouse is used by those people who are unable to use mouse with their hands or arms. For using foot mouse, install the software programs in the system then work it properly for selecting any spot of screen.

In that mouse are needed two parts, one for controlling the cursor, and other for clicking the mouse. Intelli Mouse is also knows as wheel mouse or scroll mouse and this mouse was designed by Microsoft in Its wheel set in the center between left and right button.

Users use wheel of mouse for scroll up and down any document page. If user wants to open any link on the new tab, then mouse cursor hover on the link and press down to mouse wheel. Mostly this typed of mouse uses for playing video game and graphic applications.

Touchpad is also known as Glide pad or track pad , use for giving the input to computer. These types of touch pad are place on the laptop or other special keyboards. Users can move the cursor on the screen with their fingers, and other two external buttons are embedded below track pad. Trackball is special type of mouse because one ball is placed on the surface of socket, and that sockets contain the sensors. With using sensor to detect the rotation of ball about different two axes like as upside-downside.

Trace Point mouse was designed by IBM in This component used in the traditional computer, and Trace Point is also known as Pointing stick, style pointer, or nub also. It has placed in between the G,H, and B keys on the keyboard. In Inertial and gyroscopic mouse, to be used accelerometer for detecting movement at every x-axis and y-axis. Benefits are less power consumption, enhance sensitivity, decrease weight, and more comfortable to other mouse. Tactile mouse was designed by Logitech in It contains a small size actuator for making mouse vibrate.

Main motive of designing tactile mouse is for providing education to blind persons in graphical nature. In tactile mouse is used pins and with the movement of these pins user can be able to distinguish various pictures such as triangles, squares, pentagons, hexagons, and circles.

Its main application areas are graphic designing and Auto CAD. Ergonomic mouse is vertical mice, and main objective of introducing this mouse to minimize the wrist and forearm pain because these types of problems are associated with traditional mouse while using them.

These types of mice are developed specially for computer games. Gaming mouse allow providing the flexibility to users, for using real-time strategy game like as StarCraft or multiplayer battle arena. There are various parts of a computer mouse. Here we will discuss about all parts of mouse and their functions. Buttons: Now these days, every mouse has two buttons, one is left and other right. With the help of these buttons, users can be manipulating any objects and text as well.

In the optical mouse have laser or LED, these parts allow to mouse for movement on x-axis and y-axis directions, and its parallel move the mouse cursor on the computer screen. Mouse Wheel : Main objective of wheel in mouse for scroll your document page up and down direction. Printed Circuit Board: This board is placed inside of mouse chasses, in that board all electronics components embedded such as capacitor, diode, and register etc.

This board takes input in the form of electronics signals when user given instructions by mouse such as clicking, scrolling, and more. If your mouse is wireless then require the USB receiver for getting the broadcasted signals such as Infrared, Bluetooth, Radio signals , and then give input to computer.

Battery: This component is used in the wireless mouse for running stages. Microprocessor: This is a processor that is embedded on the circuit board of mouse. Microprocessor is the brain of mouse, because without microprocessor every components of mouse are workless.

Other Internal Electronic components are:. Now these days, almost everybody aware about Mouse, but anyone in the mind some questions can be arise such as what are the uses of a computer mouse? Then here we will explain about awesome five to ten uses of computer mouse. Movement Mouse Cursor — This is main function of mouse is moving form, when we roll mouse up or down then mouse cursor move on the computer screen. Selection — With using mouse users can select any images, text, any file, and folder etc, and then can be performed other tasks such as copy, delete and paste.

Drag — Mouse allows to users for moving any objects with the help of drag — drop function. In this method, firstly select object then can be move object while pressing the mouse button, and drop object where to place it. Hovering — When mouse cursor over on the clickable object then display the information without pressing any button of mouse, and change the color of links as well. Can be go destination page, after pressing that hyperlink.

Program Execution — With the help of mouse, users can execute many task such as open file, close folder, maximize-minimize any windows, double clicks for opening object and more. Editing — Mouse allows to users to editing images in the image editor software such as Photoshop, CorelDraw, and Picasa etc. Playing Game — With using mouse, users can play various games such as chase game, in that game need mouse for selecting any particular objects. Here, we will discuss about core working principle of mechanical and optical mouse.

Such as. Mechanical Mouse Working :. Here, we will spread light on some mechanical mouse working principles are:. Optical Mouse Working:. Optical Mouse Working Principle — Optical mouse is totally different to mechanical ball mouse, because in optical mouse are operations are performed by LED light emitting diode and photo detector.

Both are placed near each other. Work of photo detector is gather all beam of light and bounced off on the surface area. The CMOS sensor gets all pictures with the help of digital signal processor which is also known as optical navigation engine. Optical navigation engine works as brain of mouse because it able to compute all pictures among of other different images.

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, [95] 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.

The computer industry often measures mouse sensitivity in terms of counts per inch CPI , commonly expressed as dots per inch DPI — the number of steps the mouse will report when it moves one inch. 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. As of , [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; [] 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, [] 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. A sensitivity converter is required in order to translate rotational movements properly. 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 aim down the weapon sights.

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 toward 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.

While modern encoders use a 2-bit i. If up to 6 bit changes would pass undetected, it would still be possible to find out the direction the encoder rotated in and then interpolate the movement of the mouse cursor. The Encoders work completely passive and simply connect or disconnect the four data cables from an input cable that can be connected to either ground or a power supply.

The button of the RKS works in a similar way using one cable for input and one for output and connecting those while pressed. Contains some historical photos. See also: Encoder remarks.
