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. Multiple mice are often used in multi-user gaming in addition to specially designed devices that provide several input interfaces. In 1986 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. 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 1990s.

  • In November 2010 a German Company called Axsotic introduced a new concept of 3D mouse called 3D Spheric Mouse.
  • This variant of the mouse resembled an inverted trackball and became the predominant form used with personal computers throughout the 1980s and 1990s.
  • Engelbart’s original mouse did not require a mousepad; the mouse had two large wheels which could roll on virtually any surface.
  • To surf the internet by touch-enabled mouse was first developed in 1996 and first implemented commercially by the Wingman Force Feedback Mouse.

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. Modern computer mice took form at the École Polytechnique Fédérale de Lausanne under the inspiration of Professor Jean-Daniel Nicoud and at the hands of engineer and watchmaker André Guignard.

Early Mice

In 2008, Motion4U introduced its “OptiBurst” system using IR tracking for use as a Maya plugin. 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.

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. Depending on how deeply hardcoded this misbehavior is, internal user patches or external 3rd-party software may be able to fix it. This often restricts one from taking a game’s existing sensitivity, transferring it to another, and acquiring the same 360 rotational measurements. A sensitivity converter is required in order to translate rotational movements properly. 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 new input points provide traditional mouse input; however, they were designed with other input technologies like touch and image in mind.

This wireless mouse was worn on a ring around a finger, which enabled the thumb to access three buttons. Despite a certain appeal, it was finally discontinued because it did not provide sufficient resolution. One roller detects the forward-backward motion of the mouse and the other the left-right motion. Opposite the two rollers is a third one 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.

Apple Desktop Bus

This driver provides the state of the buttons and the distance the mouse has moved in units that its documentation calls “mickeys”. 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. 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. In 2000, 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. Such a mouse can augment user-interfaces with haptic feedback, such as giving feedback when crossing a window boundary.

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. Based on an even earlier trackball device, the mouse device had been developed by the company since 1966 in what had been a parallel and independent discovery. As the name suggests and unlike Engelbart’s mouse, the Telefunken model already had a ball (diameter 40 mm, weight 40 g) and two mechanical 4-bit rotational position transducers with Gray code-like states, allowing easy movement in any direction. The bits remained stable for at least two successive states to relax debouncing requirements. This arrangement was chosen so that the data could also be transmitted to the TR 86 front end process computer and over longer distance telex lines with c.

Inertial And Gyroscopic Mice

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 1980s and 1990s. 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. A mouse-related controller called the SpaceBall has a ball placed above the work surface that can easily be gripped.
