Rotational Mouse
A rotational mouse is a type of computer mouse which attempts to expand traditional mouse functionality. The objective of rotational mice is to facilitate three degrees of freedom (3DOF) for human-computer interaction by adding a third dimensional input, yaw (or Rz), to the existing ''x'' and ''y'' dimensional inputs. There have been several attempts to develop rotating mice, using a variety of mechanisms to detect rotatio Mechanisms to detect rotation Mechanisms using relative measures of rotation: These devices are able to detect that the mouse has rotated by so many degrees, but cannot accurately identify where the rotation started or ended, increasing their tendency to lose orientation. 2-balls and 4-sensor sets 1985 4 saw the first mention of a rotational mouse by Nomura, H. and Saitoh, A., entitled "mouse" at the IBM Technical Disclosure Bulletin, vol. 27, no. 6, Novembre 1984. pp. 3423-3424. Other 2-ball / 4-sensor mouse concepts, patents: *"Cursor display apparatu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Computer Mouse
A computer mouse (plural mice, sometimes 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 1968. Mice originally used two separate wheels to track movement across a surface: one in the X-dimension and one in the Y. Later, the standard design shifted to utilize a ball rolling on a surface to detect motion. Most modern mice use optical sensors that have no moving parts. Though originally all mice were connected to a computer by a cable, 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 the selection of a menu item on a display. Mice often also featur ...

3DOF
Six degrees of freedom (6DOF) refers to the six mechanical degrees of freedom of movement of a rigid body in three-dimensional space. Specifically, the body is free to change position as forward/backward (surge), up/down (heave), left/right (sway) translation in three perpendicular axes, combined with changes in orientation through rotation about three perpendicular axes, often termed yaw (normal axis), pitch (transverse axis), and roll (longitudinal axis). Three degrees of freedom (3DOF), a term often used in the context of virtual reality, typically refers to tracking of rotational motion only: pitch, yaw, and roll. Robotics Serial and parallel manipulator systems are generally designed to position an end-effector with six degrees of freedom, consisting of three in translation and three in orientation. This provides a direct relationship between actuator positions and the configuration of the manipulator defined by its forward and inverse kinematics. Robot arms are ...

Hewlett-Packard
The Hewlett-Packard Company, commonly shortened to Hewlett-Packard ( ) or HP, was an American multinational information technology company headquartered in Palo Alto, California. HP developed and provided a wide variety of hardware components, as well as software and related services to consumers, small and medium-sized businesses ( SMBs), and large enterprises, including customers in the government, health, and education sectors. The company was founded in a one-car garage in Palo Alto by Bill Hewlett and David Packard in 1939, and initially produced a line of electronic test and measurement equipment. The HP Garage at 367 Addison Avenue is now designated an official California Historical Landmark, and is marked with a plaque calling it the "Birthplace of 'Silicon Valley'". The company won its first big contract in 1938 to provide test and measurement instruments for Walt Disney's production of the animated film ''Fantasia'', which allowed Hewlett and Packard to formally es ...

Apple Mouse
Apple Inc. has designed and manufactured several models of mice, trackpads and other pointing devices, primarily for use with Macintosh computers. Over the years, Apple has maintained a distinct form and function with its mice that reflect their design languages of that time. Apple's current external pointing devices are the Magic Mouse 2 and Magic Trackpad 2. Mice Mice manufactured by Apple previously only had a single button control interface, until the Mighty Mouse in 2005, which introduced a clickable scroll ball and multiple programmable buttons. Mice made by Apple contained a ball-tracking control mechanism, until the Pro Mouse in 2000 when Apple moved to an optical-based tracking mechanism. Apple's current mouse, the Magic Mouse 2, uses laser tracking. Background In 1979, Apple was planning to develop a business computer, and arranged a visit with the Xerox Parc research center to view some of their experimental technology. It was there they discovered the mouse ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
