a computer mouse is an indirect, relative, isotonic, position-control, translational input device with two degrees of freedom (x, y position) and two states (tracking, dragging). a touch screen is a direct , absolute , isometric , position-control input device with two or more degrees of freedom (x, y position and optionally pressure) and two ...
IBM sold a mouse with a pointing stick in the location where a scroll wheel is common now. A pointing stick on a mid-1990s-era Toshiba laptop. The two buttons below the keyboard act as a computer mouse: the top button is used for left-clicking while the bottom button is used for right-clicking.
A computer mouse with the most common features: two buttons (left and right) and a scroll wheel (which can also function as a button when pressed inwards) A typical wireless computer mouse. A computer mouse (plural mice, also mouses) [nb 1] is a hand-held pointing device that detects two-dimensional motion relative to a surface
Commonly, ergonomic issues can arise in an office setting. [12] [13] Many people who work in an office (either a home office or a formal office building) often spend hours sitting and working in the same position. Ergonomic considerations include chair and computer monitor height adjustment, lighting position, break frequency, and chair design ...
Logitech Cordless TrackMan Wheel trackball mose The original version of the Kensington Expert Mouse can use a standard American pool ball as a trackball. [citation needed]A trackball is a pointing device consisting of a ball held by a socket containing sensors to detect a rotation of the ball about two axes—like an upside-down ball mouse with an exposed protruding ball.

“When riding in this position, you can choose the pace, depth, and angle of penetration, which can help you find what feels best,” explains Berkheimer. How to do it:
Computer-aided ergonomics is an engineering discipline using computers to solve complex ergonomic problems involving interaction between the human body and its environment. The human body holds a great complexity thus it can be beneficial to use computers to solve problems involving the human body and the environment that surrounds it.
A rotational mouse is a type of computer mouse which attempts to expand traditional mouse functionality. [1] 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.
