What is the difference between real and perceived affordance?

Norman thus defines an affordance as something of both actual and perceived properties. The affordance of a ball is both its round shape, physical material, bouncability, etc. (its actual properties) as well as the perceived suggestion as to how the ball should be used (its perceived properties).

What are perceived affordances?

Perceived affordance, as Norman puts it, is "whether the user perceives that some action is possible (or in the case of perceived non-affordances, not possible)". For example, a button is intended to be pressed with the expectation that something will happen when it is.

What are the two kinds of affordance?

Types of affordances

They are: explicit, hidden, pattern, metaphorical, false and negative.

What is perceived affordance in HCI?

A perceived affordance is a possible action to an agent (Norman 1988). Unlike the traditional definition, a perceived affordance is primarily a relationship between an agent's cognition and the environment. This definition is commonly used within the human- computer interaction (HCI) community.
