Flat design is currently very fashionable in the field of graphics design.
Flat design is a minimalistic design approach that emphasises usability. It features clean, open space, crisp edges, bright colours and two-dimensional/flat illustrations.
Microsoft was one of the first to apply this design style to its interface with Windows 8, seen by some as a backlash against the popular skeuomorphic design that Apple kicked off with its iOS interface. Instead of converting a real-life object, such as a calendar, into a tiny realistic illustration, advocates of flat design identify apps with simple, icon-like images.
Rather than bringing aspects of real life to an interface, this illustrates a clear separation between technology and tactile objects. Simple images convey messages more quickly than detailed illustrations. Images like icons can indicate universal actions or purposes so that everyone can easily understand them.
Using Flat design graphics in training materials and eLearning design is a great way to smarten up and compliment the information you are delivering to the learner. Simplicity is the trend for both the graphics and the textual content.
