A philosophy that companies should take a user-centred approach to design, making sure they focus on the customer's needs and not on their company's needs. UX designers need to figure out what users want before building something and not after. They must also ask themselves if including "features" will provide any value to the product or service.

A theory in psychology that discusses the general idea that the whole is greater than the sum of its parts. It's based on a human need to search for stability and meaning, which leads to organic movements towards wholeness. Gestalt Theory assumes there are inherent flaws in how we perceive forms and patterns, and it holds that this innate tendency transforms into an active process of looking for order in reality.

Colours that have a relation in their hue. A colour wheel can be used to help identify analogous colours. Analogous colours are typically found next to each other on the colour wheel.

A data visualisation tool that can be used to explore and group people's thoughts or reactions to a set of concepts. Affinity diagrams are often used in user research and design thinking as an experimental technique for generating new ideas or solutions.

The emergent patterns in these visual representations can help identify which aspects your audience will respond well to, thus enabling decisions on the information architecture and next steps in the process.

It is important to note that affinity diagrams were initially developed for qualitative research but have since been adapted for quantitative research (though they are not typically used with statistical data).

A symbol that is used in the design industry to give a more personal touch. Lettermarks can be an individual's name or initials that are cleverly designed and incorporated into a company's logo.

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 design or decoration impressed into the surface of a material.

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.

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 design that features the strokes running predominantly from the upper left to the lower right.

It can also be used in reference to a type of lettering, typically for advertisements, to be read in either direction. It is also used to help the reader navigate through and around the advertisement.
