As mentioned later in this article, pointing devices have different possible states. Examples for these states are out of range, tracking or dragging. Examples. 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).
Example of a skeletal mannequin. One example of a computer system that can be used as a computer-aided ergonomics system is The AnyBody Modeling System [1] that consider the human body as a dynamic multi-rigid-body system. The human model is a public domain model contains most of the bones, muscles and joints that are present in the human body.
Soft ergonomics is the study of designing virtual interfaces that cater towards the wellness of the human body, its emotional and cognitive abilities. Soft ergonomics is a subset of ergonomics and human factors engineering , a larger body of the study of human abilities for designing equipment and devices that fit the human body.
Like other pointing devices such as mice, touchpads or trackballs, operating system software translates manipulation of the device into movements of the pointer on the computer screen. Unlike other pointing devices, it reacts to sustained force or strain rather than to gross movement, so it is called an "isometric" [ 1 ] pointing device.
Computer accessibility refers to the accessibility of a computer system to all people, regardless of disability type or severity of impairment. The term accessibility is most often used in reference to specialized hardware or software, or a combination of both, designed to enable the use of a computer by a person with a disability or impairment.
Hands-on computing is a branch of human-computer interaction research which focuses on computer interfaces that respond to human touch or expression, allowing the machine and the user to interact physically. Hands-on computing can make complicated computer tasks more natural to users by attempting to respond to motions and interactions that are ...
Key Ovation makes the Goldtouch ergonomic keyboard which is an adjustable angled split keyboard. On some ergonomic keyboards, the tenting angle is increased to 90° so the user types with their hands perpendicular to the ground, thumbs-up, [9] similar to the hand position adopted by accordion players.
A 3D mouse is a computer input device for viewport interaction with at least three degrees of freedom , e.g. in 3D computer graphics software for manipulating virtual objects, navigating in the viewport, defining camera paths, posing, and desktop motion capture. 3D mice can also be used as spatial controllers for video game interaction, e.g ...
