7th November 2011 Lecture

The first thing that lecturer talk about is about "customer always king".
always ask the user how to satisfy them because without them, your interface is nothing.

this week lecture is mainly about Affordance.

An affordance is a quality of an object, or an environment, which allows an individual to perform an action. For example, a knob affords twisting, and perhaps pushing, while a cord affords pulling. The term is used in a variety of fields: perceptual psychology, cognitive psychology, environmental psychology, industrial design, human–computer interaction (HCI), interaction design, instructional design and artificial intelligence.

we must design to suit the user so that the user love to use our interface. we have to make sure that our interface can communicate well with our user. the user can understand the design and did not frustrate while try to get use to it.


The perceived affordance an object (or interface element) is determined by factors including:

• context: the environment or process in which the element is displayed;
• culture: the influence of societal ‘norms’ on the individual’s understanding and use of a object;
• instinct: an unconscious association, often linked to phsical characteristics, for example, the size of an object in relation to the human form;
• mental model: the user’s understanding and expectations of interaction with the object.
