In design, we cannot rely on this natural relationship. Some affordances are less obvious, and many yet to be realised, but with objects in the real, physical world, there is a natural and direct relationship between the perceptible qualities of tangible things and what we can do with them. For example, just by looking at a glass we can determine that the object affords holding liquid, so we can quench our thirst. These interpretations allow us to both determine an object's possible uses and analyse how they might help us achieve our aims and objectives. Whether through experience or some innate ability (we will leave this debate for another day), we are capable of assessing objects according to their perceptible properties.

Norman borrowed the term and concept from the world of James J. ![]() How to define 'Affordance'ĭon Norman first mentioned affordances in the context of design in The Design of Everyday Things (1988). Don Norman introduced this term to the design community.ĭespite Don Norman’s best efforts, the underlying meaning of the term is sometimes misunderstood. 'Affordance' is a term most designers will have come across at some stage of their studies and careers.
