Computer Mouse computer mouse
The driver software in the system converts the signals into motion of the mouse cursor along X and Y axes on the computer screen. 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 and other functions such as changing posture. Since the mouse serves for aiming, a mouse that tracks movement accurately and with less lag 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.
PC Gamer”. Later, inspired by the Star, Apple Computer released the Apple Lisa, which also used a mouse. Only with the release of the Apple Macintosh in 1984 did the mouse see widespread use. Windows 98 added built-in support for USB Human Interface Device class , with native vertical scrolling support.
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. On 14 November 1963, he first recorded his thoughts in his personal notebook about something he initially called a “bug”, which in a “3-point” form could have a “drop point and 2 orthogonal wheels”. He wrote that the “bug” would be “easier” and “more natural” to use, and unlike a stylus, it would stay still when let go, which meant it would be “much better for coordination with the keyboard”. In 1988, 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 1990s, the Super Nintendo Entertainment System video game system featured a mouse in addition to its controllers.
Inertial And Gyroscopic Mice
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. In combination with a wireless keyboard an inertial mouse can offer alternative ergonomic arrangements which do not require a flat work surface, potentially alleviating some types of repetitive motion injuries related to workstation posture. 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.
- A digital computer calculated the tracks and sent the resulting data to other ships in a task force using pulse-code modulation radio signals.
- “Connect a Bluetooth device that does not have or require a transceiver”.
- The introduction of Windows Vista and Microsoft Surface introduced a new set of input APIs that were adopted into Windows 7, allowing for 50 points/cursors, all controlled by independent users.
- 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.
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.
Cordless Or Wireless
In the 1970s, the Xerox Alto mouse, and in the 1980s 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. 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.
By 1982, the Xerox 8010 was probably the best-known computer with a mouse. Hawley, who manufactured mice for Xerox, stated that “Practically, I have the market all to myself right now”; a Hawley mouse cost $415. In 1982, Logitech introduced the P4 Mouse at the Comdex trade show in Las Vegas, its first hardware mouse. That same year Microsoft made the decision to make the MS-DOS program Microsoft Word mouse-compatible, and developed the first PC-compatible mouse. Microsoft’s mouse shipped in 1983, thus beginning the Microsoft Hardware division of the company.
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. 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. Ball mice and wheel mice were manufactured for Xerox by Jack Hawley, doing business as The Mouse House in Berkeley, California, starting in 1975.
The mouse was a simple optomechanical device, and the decoding circuitry was all in the main computer. 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.
