Taking this course will teach you both the theory of affordances and also how to build instantly perceptible affordances into your own designs. Your users should be able to identify the actions afforded by a design with speed and accuracy. Thus, the better you can make your affordances, the more likely you will prevent the user from becoming frustrated (which can happen very quickly). In order to achieve this, you as a designer must appreciate how users perceive the world and how experience, context, culture, constraints and other factors affect our ability to detect the possibilities of actions on offer. This is at the heart of why those interested in a design career and established designers alike must gain a firm grounding in the meaning and potential application of affordances as a designer’s tool.

The word “affordance” was originally invented by the perceptual psychologist J. J. Gibson (1977, 1979) to refer to the actionable properties between the world and an actor (a person or animal). To Gibson, affordances are a relationship. They are a part of nature: they do not have to be visible, known, or desirable. Some affordances are yet to be discovered. Some are dangerous. I suspect that none of us know all the affordances of even everyday objects.
