Infographics is a style of showing information in a simple graphical way, either static (images) or dynamic (animations) with the minimum necessary detail over a particular topic. The most common examples are traffic signals and subway maps. Main concepts are replaced by basic and well known shapes such as people, vehicles, bridges, houses and so on.
To achieve a fast and clear perception from viewers, images and information are reduced and combined and differentiated using areas, layers, colors and other visual cues such as legends.
In the past, most user interfaces used graphical styles with prevalence of cartoonish images (icons) and 3D and polylined controls. This is changing to more simple and less bloated environments.
Maybe Star Trek designer Mike Okuda, with his LCARS interface, was a visionary ahead of his time. The simplified interface can be seen in some of today’s applications.
And don’t forget Einstein’s phrase: “make things as simple as possible, but no simpler“. There must exists equilibrium between simplicity and usability.
