The intensity of a color relative to its own brightness. Colours are said to be saturated when they have a strong hue and high intensity.
A UX design technique in which you divide your users into groups, show them cards with different names for unrelated objects and ask them to categorise them.
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).
Designers and developers use font styles to denote differences in meaning between two or more words, phrases, sentences, paragraphs, or blocks of text. Typical font styles in CSS and web development are normal, italic, oblique and inherit.
Framing consisting of cutting off or obscuring most of the surrounding of a subject, removing distractions from the background and emphasising the subject.
A UX design technique to explore and map out a service, product, or system through physical navigation, often completed at the start of a design process to provide designers with an understanding of how users will navigate the system. In addition, body-storming can be used in development to test functionality or measure ease of use.
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.
A type of font that comes pre-installed in an operating system.
A statistical method in which two variants of the same activity are compared against each other (typically with several variants), one at a time, and the most effective variant is selected.
A form of typographic ornament used by a type designer for decorative purposes. Common ligatures are based on joining two or more letters together, often with figures embedded in the design
A well-known cognitive psychologist's principle that says that the time it takes to make a decision varies logarithmically according to the number of choices. As more options are presented, more decision time is required due to the mental work of comparing and contrasting each potential option.
