The art and discipline of putting together set of typefaces into a harmonious and readable type system. A typeface designer spends much time considering many things such as clear visual message, readability at different sizes, legibility at small point sizes, ease of use for printing processes on its own or over the top of other fonts.

A way of researching users and understanding their behaviour in the context of the product, helping designers in understanding users' needs and expectations and what motivates them to act.

Designers can use this type of research to understand better their users and what kinds of experiences they are looking for. And this will allow the designers better empathize with their users, making them a part of the learning cycle.

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.

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 small, non-preview image that accompanies a larger image. It provides an immediate sense of the content while not necessarily revealing it in its entire scope.

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.
