Usually the first functional form of a new product, created to test a concept or prove out some aspects of design.
A way of developing new products or services using a process of repeated and regular refinement, in which prototypes are made, evaluated, revised, and re-evaluated until the desired result is achieved. High profile companies have successfully implemented iterative design to create effective and innovative products.
The surface quality of an element.
The unused or empty space in a composition of images, either two-dimensional (as with paintings) or three-dimensional (as with sculptures).
The distance between the baseline and the mean line of lowercase letters in a typeface. Nearby descenders (such as j) and ascenders (such as q) usually extend slightly below or above this height.
Also known as an Ishikawa diagram, is a widely used technique in project management. The diagram provides a means of evaluating the cause-and-effect relationship between the various activities necessary for completing a project by visualising all activities in the project as bones that interconnect on an anterior and posterior spine, with causality flowing from one to another.
A prediction model used in human-computer interaction. It states that the time required to move to a target area rapidly increases as the distance to the target increases. The law was proposed by Paul Fitts, an American psychologist, in 1954 as a mathematical model of movement with limited cognitive capacity.
Fitts hypothesized that one would quickly select its first apparent target when reaching for an object before considering alternatives — a phenomenon called "target fixation." This tendency would increase progressively with increased distance between the subject and object until it eventually became exponential (i.e., too far away).
A set of symbols or "characters" including letters, numbers and various other symbols.
Layout is a defining characteristic of design. It dictates the positioning of content and design elements. Layouts can range from the simple, such as a four- or two-column layout, to more complex designs like grids with multiple hierarchy levels.
A group of rules, guidelines, and/or standards designers use when producing artwork or branded projects ensuring that they have the desired appearance and are compliant with usage guidelines.
The ratio of a rectangle's width to its height. It is measured by dividing the shorter side length, here "w" or width, by the longer side length, "h" or height. The aspect ratio may be given as either a fraction or as a decimal.
