In a computer system, various features, such as a keyboard, mouse, and screen display afford pointing, looking and selecting it is not sufficient to build affordances into a design it is necessary that a user actually perceives the affordances that are offered, eg, that clicking with a mouse will result in a useful or meaningful outcome.
