For desktop computers, whhat mouse is placed on a flat surface e. The picture is an example of a Logitech desktop computer mouse with two primary buttons and a wheel. But, due to Alto's lack of success, the first widely used application of the mouse was with the Apple Lisa computer. Today, this pointing device is on virtually every computer. Below is a list of computer mouse functions to give you an idea of all the things a mouse is capable of doing.
For help with using a mouse and performing all the above functions, see: How to use a computer mouse. When using a computer mouse, you don't have to memorize commands, such as those utilized in a text-based command line environment like MS-DOS.
For example, in MS-DOS, you would need to know the cd command and dir command and type the commands on computeer keyboard to open a directory folder and view its files. Whereas a Windows user only has to double-click to open a folder and see its contents. Below is a listing of all the si of computer mice and pointing devices used with a computer.
Today, for a desktop computer, the most common type of mouse is an optical mouse that connects to the USB port and known as a USB mouse. For laptop computers, the most common type of mouse is the touchpad. Today, most computer mice connect to a computer using a USB port. Below is a list of ports and wireless connections a mouse is capable of using.
The parts of a computer mouse can vary by the type of computer mouse. Below is a general overview of the parts found on most computer mice. Today, almost all computer mice have at least two buttons, a left button and right button for clicking and manipulating objects and text.
In the past, there were mice with only one button. For example, many of the early Apple computer mice only had one button. A desktop mouse uses a ball and rollers if it's a mechanical mouse or a laser or LED if it's an optical mouse. These components track the movement of the mouse on an x-axis and y-axis and move the mouse cursor on the screen.
In the picture is an example of the bottom of a mechanical and optical mouse. Today's cimputer computer mice also usually include a mouse wheel that allows you to scroll up and down on a page. What is new at the smithsonian museums transmit input all mouse signal information, clicks, and other information, the mouse must also have a circuit board with integrated circuits.
For a whst mouse, it also includes a cable with a plug that connects to the computer. Today, most corded mice connect to the USB port. If your computer has a wireless mouse, it needs a USB mousse receiver to receive the wireless signal and input it into the computer.
If you're using a laptop, some of the above components mentioned earlier are not required. For example, a touchpad does not use a ball, laser, whar LED to control movement; it uses your finger on the touchpad.
Other vomputer include a ball for trackball mice, extra buttons on the thumb side of the mouse, and nubs used with laptop mice. Because a laptop is designed for portability, almost all laptops today use a touchpad as the mouse, and some Lenovo laptops still use a TrackPoint.
What foods can muslims not eat, all laptop computers can have a USB corded or wireless mouse attached to them. Mouae the picture is an example of a touchpad found below a laptop keyboard. Smartphones and tablets use a touch screen as their primary input device, and therefore your xomputer is the mouse on these devices.
With most tablets, you also have the option to connect a computer mouse and use it on the tablet. By default, a computer mouse is set up to be used with your right hand. However, if you're left-handed, what can i do with a computer can be set up to be used with your left hand. Although a mouse can be set up for your left hand, some mice are molded for right-hand users and may feel uncomfortable with your left hand.
The following page explains the mouse basics, how it's held, how to connect it, and how it's used on the computer. Included on the page are interactive examples that help with practicing with the different compuher features.
To change the batteries in your mouse, you slide back the cover on the bottom, switch out the old batteries, and then replace the cover. When talking about one singularrefer to a computer mouse as a "mouse. To help prevent confusion, some companies and writers avoid using either plural form of a mouse by referring to multiple mice as "mouse devices. Some believe that mouse is short for "manually-operated user-select equipment.

What Does Mouse Mean?
Sep 19, · What is Computer Mouse Definition – Mouse is a pointing input device of computer. Mouse help to control cursor that is visible on the computer screen while moving the mouse on flat surface place. Its name was originated by its shape that look as mouse, because it . Sep 01, · A mouse is a hand-held device used for directly interacting with a graphical user interface (GUI) by controlling the movement of a cursor or pointer on a computer s display screen. The mouse detects the two-dimensional motion of the operator and translates it into the movement of the cursor on the screen.
A computer mouse plural mice , rarely mouses  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. The first public demonstration of a mouse controlling a computer system was in Mice originally used a ball rolling on a surface to detect motion, but modern mice mostly have optical sensors that have no moving parts.
Originally wired to a computer, many modern mice are cordless, relying on short-range radio communication with the connected system. In addition to moving a cursor, computer mice have one or more buttons to allow operations such as 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.
The earliest known written use of the term mouse in reference to a computer pointing device is in Bill English's July publication, "Computer-Aided Display Control" likely originating from its resemblance to the shape and size of a mouse , a rodent , with the cord resembling its tail. The plural for the small rodent is always "mice" in modern usage. The plural for a computer mouse is either "mice" or "mouses" according to most dictionaries, with "mice" being more common.
Licklider 's "The Computer as a Communication Device" of Benjamin's project used analog computers to calculate the future position of target aircraft based on several initial input points provided by a user with a joystick. Benjamin felt that a more elegant input device was needed and invented what they called a "roller ball" for this purpose. The device was patented in ,  but only a prototype using a metal ball rolling on two rubber-coated wheels was ever built, and the device was kept as a military secret.
Another early trackball was built by Kenyon Taylor , a British electrical engineer working in collaboration with Tom Cranston and Fred Longstaff. The trackball used four disks to pick up motion, two each for the X and Y directions. Several rollers provided mechanical support.
When the ball was rolled, the pickup discs spun and contacts on their outer rim made periodic contact with wires, producing pulses of output with each movement of the ball. By counting the pulses, the physical movement of the ball could be determined. A digital computer calculated the tracks and sent the resulting data to other ships in a task force using pulse-code modulation radio signals.
This trackball used a standard Canadian five-pin bowling ball. It was not patented, since it was a secret military project. Douglas Engelbart of the Stanford Research Institute now SRI International has been credited in published books by Thierry Bardini ,  Paul Ceruzzi ,  Howard Rheingold ,  and several others    as the inventor of the computer mouse.
Engelbart was also recognized as such in various obituary titles after his death in July By , Engelbart had already established a research lab at SRI, the Augmentation Research Center ARC , to pursue his objective of developing both hardware and software computer technology to "augment" human intelligence.
That November, while attending a conference on computer graphics in Reno, Nevada , Engelbart began to ponder how to adapt the underlying principles of the planimeter to inputting X- and Y-coordinate data.
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. Several other experimental pointing-devices developed for Engelbart's oN-Line System NLS exploited different body movements — for example, head-mounted devices attached to the chin or nose — but ultimately the mouse won out because of its speed and convenience.
On October 2, , a mouse device named Rollkugel German for "rolling ball" was described as an optional device for its SIG terminal. It was developed by the German company Telefunken. It was based on an earlier trackball-like device also named Rollkugel that was embedded into radar flight control desks. When the development for the Telefunken main frame TR [ de ] began in , Mallebrein and his team came up with the idea of "reversing" the existing Rollkugel into a moveable mouse-like device, so that customers did not have to be bothered with mounting holes for the earlier trackball device.
Together with light pens and trackballs, it was offered as an optional input device for their system since Footage exists from January , filmed at Abbey Road studios, of Ringo Starr holding what appears to be a mouse, possibly using it as a remote, to start or stop a recording machine. Some Rollkugel mouses installed at the Leibniz-Rechenzentrum in Munich in are well preserved in a museum. The Xerox Alto was one of the first computers designed for individual use in and is regarded as the first modern computer to utilize a mouse.
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 Star in By , the Xerox was probably the best-known computer with a mouse. The Sun-1 also came with a mouse, and the forthcoming Apple Lisa was rumored to use one, but the peripheral remained obscure; Jack Hawley of The Mouse House reported that one buyer for a large organization believed at first that his company sold lab mice.
Microsoft's mouse shipped in , thus beginning the Microsoft Hardware division of the company. A mouse typically controls the motion of a pointer in two dimensions in a graphical user interface GUI. 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 relative movements of the mouse on the surface are applied to the position of the pointer on the screen, which signals the point where actions of the user take place, so hand movements are replicated by the pointer.
For example, a text file might be represented by a picture of a paper notebook and clicking while the cursor hovers this icon might cause a text editing program to open the file in a window. Different ways of operating the mouse cause specific things to happen in the GUI: .
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. Gestural interfaces occur more rarely than plain pointing-and-clicking; and people often find them more difficult to use, because they require finer motor control from the user.
However, a few gestural conventions have become widespread, including the drag and drop gesture, in which:. For example, a user might drag-and-drop a picture representing a file onto a picture of a trash can , thus instructing the system to delete the file. Other uses of the mouse's input occur commonly in special application-domains. In interactive three-dimensional graphics , the mouse's motion often translates directly into changes in the virtual objects' or camera's orientation.
For example, in the first-person shooter genre of games see below , players usually employ the mouse to control the direction in which the virtual player's "head" faces: moving the mouse up will cause the player to look up, revealing the view above the player's head. A related function makes an image of an object rotate, so that all sides can be examined. 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.
For example, on platforms with more than one button, the Mozilla web browser will follow a link in response to a primary button click, will bring up a contextual menu of alternative actions for that link in response to a secondary-button click, and will often open the link in a new tab or window in response to a click with the tertiary middle mouse button.
The German company Telefunken published on their early ball mouse on 2 October The ball mouse replaced the external wheels with a single ball that could rotate in any direction. It came as part of the hardware package of the Xerox Alto computer. Perpendicular chopper wheels housed inside the mouse's body chopped beams of light on the way to light sensors, thus detecting in their turn the motion of the ball.
This variant of the mouse resembled an inverted trackball and became the predominant form used with personal computers throughout the s and s. The Xerox PARC group also settled on the modern technique of using both hands to type on a full-size keyboard and grabbing the mouse when required. The ball mouse has two freely rotating rollers.
These are located 90 degrees apart. One roller detects the forward—backward motion of the mouse and other the left—right motion. Opposite the two rollers is a third one white, in the photo, at 45 degrees 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.
Simple logic circuits interpret the relative timing to indicate which direction the wheel is rotating. This incremental rotary encoder scheme is sometimes called quadrature encoding of the wheel rotation, as the two optical sensors produce signals that are in approximately quadrature phase. The mouse sends these signals to the computer system via the mouse cable, directly as logic signals in very old mice such as the Xerox mice, and via a data-formatting IC in modern mice.
The driver software in the system converts the signals into motion of the mouse cursor along X and Y axes on the computer screen. The ball is mostly steel, with a precision spherical rubber surface. 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  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,  flying mice, or wands,  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.
