Pointing Stick
A pointing stick (or trackpoint, also referred to generically as a nub or nipple) is a small analog stick used as a pointing device typically mounted centrally in a computer keyboard. Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer or cursor on the monitor. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" pointing device. IBM introduced it commercially in 1992 on its laptops under the name "TrackPoint", patented in 1997. The pointing stick senses applied force by using two pairs of resistive strain gauges. A pointing stick can be used by pushing with the fingers in the general direction the user wants the cursor to move. The velocity of the pointer depends on the applied force so increasing pressure causes faster movement. The relation between pressure and cursor or pointer spee ...

Mouse Pointing Stick
A mouse ( : mice) is a small rodent. Characteristically, mice are known to have a pointed snout, small rounded ears, a body-length scaly tail, and a high breeding rate. The best known mouse species is the common house mouse (''Mus musculus''). Mice are also popular as pets. In some places, certain kinds of field mice are locally common. They are known to invade homes for food and shelter. Mice are typically distinguished from rats by their size. Generally, when a muroid rodent is discovered, its common name includes the term ''mouse'' if it is smaller, or ''rat'' if it is larger. The common terms ''rat'' and ''mouse'' are not taxonomically specific. Typical mice are classified in the genus '' Mus'', but the term ''mouse'' is not confined to members of ''Mus'' and can also apply to species from other genera such as the deer mouse, ''Peromyscus''. Domestic mice sold as pets often differ substantially in size from the common house mouse. This is attributable to breeding ...

Space Bar
The space bar is on the bottom center of the keyboard The space bar, spacebar, blank, or space key is a key on a typewriter or alphanumeric keyboard in the form of a horizontal bar in the lowermost row, significantly wider than all other keys. Its main purpose is to conveniently enter a space, e.g., between words during typing. History Originally, (on early writers dating back to the late 19th century) the "bar" was literally a metal bar running across the full width of the keyboard (or even wider, and even surrounding it) that triggered the carriage advance without also firing any of the typebars towards the platen. Later examples gradually shrank and developed into their current more ergonomic form as a wide, centrally located but otherwise apparently normal "key", as typewriter (and computer) keyboards began to incorporate additional function keys and were more deliberately "styled". Although it varies by keyboard type, the space bar usually lies between the Alt keys (or Com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Patent
A patent is a type of intellectual property that gives its owner the legal right to exclude others from making, using, or selling an invention for a limited period of time in exchange for publishing an enabling disclosure of the invention."A patent is not the grant of a right to make or use or sell. It does not, directly or indirectly, imply any such right. It grants only the right to exclude others. The supposition that a right to make is created by the patent grant is obviously inconsistent with the established distinctions between generic and specific patents, and with the well-known fact that a very considerable portion of the patents granted are in a field covered by a former relatively generic or basic patent, are tributary to such earlier patent, and cannot be practiced unless by license thereunder." – ''Herman v. Youngstown Car Mfg. Co.'', 191 F. 579, 584–85, 112 CCA 185 (6th Cir. 1911) In most countries, patent rights fall under private law and the patent holder ...

PARC (company)
PARC (Palo Alto Research Center; formerly Xerox PARC) is a research and development company in Palo Alto, California. Founded in 1969 by Jacob E. "Jack" Goldman, chief scientist of Xerox Corporation, the company was originally a division of Xerox, tasked with creating computer technology-related products and hardware systems. Xerox PARC has been at the heart of numerous revolutionary computer developments, including laser printing, Ethernet, the modern personal computer, GUI (graphical user interface) and desktop paradigm, object-oriented programming, ubiquitous computing, electronic paper, a-Si (amorphous silicon) applications, the computer mouse, and VLSI (very-large-scale integration) for semiconductors. Unlike Xerox's existing research laboratory in Rochester, New York, which focused on refining and expanding the company's copier business, Goldman's “Advanced Scientific & Systems Laboratory” aimed to pioneer new technologies in advanced physics, materials science, and ...

Ted Selker
Edwin Joseph Selker, better known as Ted Selker, is an American computer scientist known for his user interface inventions. Biography Selker graduated from Brown University in 1979 with a BS in Applied Mathematics, and from the University of Massachusetts Amherst with an MS in Computer and Information Sciences in 1981. From June 1981 to 1983 he worked as research assistant in the Stanford University, Robotics Laboratory.

Pointing Stick Toshiba
Pointing is a gesture specifying a direction from a person's body, usually indicating a location, person, event, thing or idea. It typically is formed by extending the arm, hand, and index finger, although it may be functionally similar to other hand gestures. Types of pointing may be subdivided according to the intention of the person, as well as by the linguistic function it serves. Pointing typically develops within the first two years of life in humans, and plays an important role in language development and reading in children. It is central to the use of sign language, with a large number of signs being some variation on pointing. The nature of pointing may differ for children who have autism or who are deaf, and may also vary by gender. It is typically not observed in children who are blind from birth. Pointing may vary substantially across cultures, with some having many distinct types of pointing, both with regard to the physical gestures employed and their interpre ...

Scroll Wheel
A scroll wheel is a wheel used for scrolling. The term usually refers to such wheels found on computer mice (where they can also be called a mouse wheel). It is often made of hard plastic with a rubbery surface, centred around an internal rotary encoder. It is usually located between the left and right mouse buttons and is positioned perpendicular to the mouse surface. Sometimes the wheel can be pressed left and right, which is actually just two additional macros buttons. Functionality The scroll wheel is placed horizontally between the mouse buttons and commonly uses vertical scrolling, wherein rolling the wheel from the bottom side to the top is known as scrolling "upward" or "forward", while the reverse, i.e. rolling the wheel from the top side to the bottom, is known as scrolling "downward" or "backward". In a graphical user interface, the "upward" motion moves contents of the window downward (and the scrollbar thumb, if present, upward), and vice versa. In other confi ...

D-pad
A D-pad (short for directional pad or digital pad; officially referred to by Nintendo as a +Control Pad) is a flat, usually thumb-operated, often digital, four-way directional control with one button on each point, found on nearly all modern video game console gamepads, game controllers, on the remote control units of some television and DVD players, and smart phones. Like early video game joysticks, the vast majority of D-pads are digital; in other words, only the directions provided on the D-pad buttons can be used, with no intermediate values. However, combinations of two directions (up and left, for example) do provide diagonals and many modern D-pads can be used to provide eight-directional input if appropriate. Although D-pads offer less flexibility than analog sticks, they can easily be manipulated (requiring little movement of the thumb) with very high accuracy. They are also far less demanding in maintenance and do not protrude very far from the controller, making t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
