PRINCIPLES OF DESIGN

mental models are what people really have in their heads and what guides

their use of things.

MENTAL MODEL

PRINCIPLES OF DESIGN

•Make things visible

•Provide a good conceptual model• Affordance

• Mapping

• Constraints

• Feedback

Just by looking the user should know the state of the system & possible actions

The correct parts must be visible and they must convey the correct message.

Visibility problems occur when clues are lacking or exist in excess

Don’t violate these principles to make something “look good”!

VISIBILITY

Just by looking at the object, a user should know how to use it.

Make the appropriate actions visible and make the inappropriate actions invisible.

AFFORDANCE

Controls and displays should exploit natural mapping.

Natural mapping takes advantage of physical analogies and cultural standards.

Physical: Steering wheelCultural: red means stop, green means go.

MAPPING

Constraints limit the ways in which something can be used.

Ensure correct procedure by making it impossible to do otherwise.

CONSTRAINTS

Feedback are clues given to the user that they have been successful

Good design contains feedback

FEEDBACK

DESIGN PROCESS

ITERATIVE DESIGN

“learning by creating”

“Iterating is designing and, more specifically, understanding what one is designing through actually creating it. . . . Iterative design also means that until

you have actually built what you are designing, you are not going to be able to fully understand it.

--Anders Ramsay, http://www.andersramsay.com/2009/03/01/three-reasons-to-start-designing-iteratively
