The dynamic characteristics of a system are described in terms of the dialogue requirements contained in seven principles of part 10 of the ergonomics standard, the ISO 9241. This standard establishes a framework of ergonomic "principles" for the dialogue techniques with high-level definitions and illustrative applications and examples of the ...
Usability, also known as Ease of use – Capacity of a system for its users to perform tasks; Business performance management – Processes to bring output into alignment with goals; Productivity – Average measure of the efficiency of production; Safety – State of being secure from harm, injury, danger, or other non-desirable outcomes
The first known solution to the hidden-line problem was devised by L. G. Roberts [1] in 1963. However, it severely restricts the model: it requires that all objects be convex. Ruth A. Weiss of Bell Labs documented her 1964 solution to this problem in a 1965 paper. [2] In 1966 Ivan E. Sutherland listed 10 unsolved problems in computer graphics. [3]
Fitts's law (often cited as Fitts' law) is a predictive model of human movement primarily used in human–computer interaction and ergonomics. The law predicts that the time required to rapidly move to a target area is a function of the ratio between the distance to the target and the width of the target. [1]
Graphic representation of a minute fraction of the WWW, demonstrating hyperlinks.. Graph drawing is an area of mathematics and computer science combining methods from geometric graph theory and information visualization to derive two-dimensional depictions of graphs arising from applications such as social network analysis, cartography, linguistics, and bioinformatics.
The mass availability of computer graphics. Computer graphics capabilities such as image processing, graphics transformations, rendering, and interactive animation become widespread as inexpensive chips become available for inclusion in general workstations and mobile devices. Mixed media. Commercial systems can handle images, voice, sounds ...
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. The model has more than 1000 ...
However, they usually can model multiple layers (conceptually of ink, paper, or film; opaque, translucent, or transparent—stacked in a specific order. The ordering is usually defined by a single number (the layer's depth, or distance from the viewer). Layered models are sometimes called "2 1 ⁄ 2-D computer graphics". They make it possible ...
