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]
ISO 9241 is a multi-part standard from the International Organization for Standardization (ISO) covering ergonomics of human-system interaction and related, human-centered design processes (see also human-computer interaction). It is managed by the ISO Technical Committee 159.
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.
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 ...
Computer Eye Syndrome is an umbrella term for many problems but the causes of these problems can be easily identified. When using a computer due to the size and setup of the monitor and components it is necessary for the user to be within at least two feet of the monitor when performing any type of computational work.
On 2D displays, such as computer monitors and TVs, display size or viewable image size (VIS) refers to the physical size of the area where pictures and videos are displayed. The size of a screen is usually described by the length of its diagonal , which is the distance between opposite corners, typically measured in inches.
A 4:3 monitor. Until about 2003, most computer monitors used an aspect ratio of 4:3, and in some cases 5:4. For cathode ray tubes (CRTs) 4:3 was most common even in resolutions where this meant the pixels would not be square (e.g. 320×200 or 1280×1024 on a 4:3 display).
