PNG Image

A PNG (Portable Network Graphics) file is a bitmap image format that has been designed to store images with an alpha channel. This format is primarily used for transparency so that it can be placed over other graphics in many design applications.

UX Roadmap

Layout is a defining characteristic of design. It dictates the positioning of content and design elements. Layouts can range from the simple, such as a four- or two-column layout, to more complex designs like grids with multiple hierarchy levels.

Fitts' Law

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 intensity of a color relative to its own brightness. Colours are said to be saturated when they have a strong hue and high intensity.

Dark Pattern

A type of user interface design carefully crafted to trick people into doing things they might not want to do.

Design Thinking

An iterative process that designers use to understand the user, challenge assumptions, and redefine the problems to identify alternative strategies and solutions that might not be instantly apparent with our initial level of understanding. Design Thinking provides a solution-based approach to solving problems. It is a way of thinking and working as well as a collection of hands-on methods.


Designs that are created in one colour. It can be any colour, but the whole design will range from light to darker shades. As the name implies, it is typically a single hue, with black and white also being typical combinations for this type of design.
