PPI stands for Point Per Inch. PPI is the number of dots per inch in a printer's resolution or the number of pixels per inch in a monitor's screen resolution. The more PPI, the higher your image quality will be as it becomes sharper and clearer. The lower your PPI, the lower your image quality will be, and the more likely you'll see individual pixels in an image.
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.
Also known as an Ishikawa diagram, is a widely used technique in project management. The diagram provides a means of evaluating the cause-and-effect relationship between the various activities necessary for completing a project by visualising all activities in the project as bones that interconnect on an anterior and posterior spine, with causality flowing from one to another.
The relative lightness or darkness of a hue.
The surface quality of an element.
The width and height of a document, after having been cut down to size from a larger sheet.
Typefaces that are used across large bodies of text like headlines. Text typefaces are generally more varied than body-text typefaces.
A type of design where the colours or tones gradually change from one colour to another. Gradients are often used in graphic design to add visual interest and give the appearance of "extensions" or "glosses" of a particular colour.
The art and science of arranging information so that it's intuitive to find, easy to navigate, presents a cohesive design, meets accessibility guidelines, looks attractive on any device or screen size and ultimately drives behaviour change.
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).
One of the most common types of navigation in UI design. It's usually a system of one or more horizontal buttons placed at the bottom of the screen, directing users to other parts of an app or website. Bottom navigation is often used as an alternative to scrolling or tabbing through links on a page.
