A way to create and test designs. Designers use design sprints as a time-intensive method of quickly testing ideas and then pivoting into designing for user needs. A designer may then take the prototype they created on the first day of the design sprint and fix any usability issues with it, which is a quick way to get feedback on their work before continuing development.
The number of visits that result in a purchase or some other goal. It can measure any conversion event, such as download, registration, purchase, etc.
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.
How well or poorly something can be read.
The design of the interaction between users and products. Interaction design is focused on creating products that enable the user to achieve their objective(s) in the best way possible.
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).
The placement or otherwise of a thing in relation to other things. In design, proximity may be considered as the distance between two items in space or their relative location to each other.
A set of colors which can be used to create a particular visual effect. It is usually composed of multiple primary, secondary, and tertiary colours.
A selector that can be applied to any HTML element. ID should be used when designing for a single instance, such as using the id="main" attribute on an <h1> tag.
A technique used to sequentially present items in a list or other data set that are too long to display at one time.
A field of study that aims to understand the user experience of a product or service. Conducting UX research includes interviewing, observing, and surveying users. Understanding the user experience is important because it helps designers understand how to design a better product that will be more appealing and usable for people.
