A process in which subjects use a product or service under test conditions and report their experience.
The degree of difference between the two sides of an object or system.
A type of text used as filler or placeholder text. Since the dawn of time, it has been around and is sometimes erroneously referred to as "a nonsense sentence used by printers who have run out of typesetting space".
The unused or empty space in a composition of images, either two-dimensional (as with paintings) or three-dimensional (as with sculptures).
A software developer who designs, develops, maintains and supports the entire end-to-end product. These developers are capable of developing and implementing modern solutions to any industry problem. They typically work with different technologies such as mobile application development, web application development, back-end software development and front-end software development.
An imaginary line on which most letters "sit". As such, it equals the height of an em square. The expected result of a baseline is to reference the height with which text is aligned. The alignment ranges from ascenders, which are the upper strokes in b, d, and h, down to descenders like j or y.
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).
An Encapsulated PostScript file (.eps) is a vector graphics format. EPS files are typically used to exchange artwork between different design programs, such as Adobe Illustrator and other vector graphics applications, including CorelDRAW, Inkscape, SIAE Draw and others. EPS files can also be used to provide a file format for print.
The principle of both sides of an object having a sense of symmetry. It ensures that the weight and visual mass are distributed evenly on both sides of a surface. Balance is more important than symmetry because people don't often notice when something is asymmetrical, but they will always see if something is unbalanced.
Black, white, and all the values of shades in between.
The main text of an advertisement or editorial as opposed to headings and subheadings.
