When there are fewer features than functions, the user becomes confused because the “hidden” functions are not immediately obvious. I particularly agreed with and enjoyed the chapter on developing conceptual models and mapping features to functions. The user must be able to figure out what to do with the object and be able to understand that an action has been completed. The overall take home message is that successful products will provide the user with visibility and feedback. Norman argues that a product with external physical cues and easily interpreted internal relationships that allow the user to understand intended actions provides the user with the most comfortable experience. However, knowledge in the head allows for more efficiency when performing tasks. Knowledge in the world relieves the user from memorizing every detail about how to use a certain product. Exploit the power of constraints, both natural and artificial. Make things visible: bridge the gulfs of Execution and Evaluation.ĥ. Use both knowledge in the world and knowledge in the head.ģ. The seven principles for transforming difficult tasks into simple ones are listed below.ġ. Norman outlines the guiding principles to good design.

Every day, we are bombarded with choices such as pulling, pushing, sliding, flipping, pressing, etc. If a mistake is made, it is never the user’s fault, it is due to poor design. Products should be usable and understandable without requiring the user to consult the user manual. Norman emphasizes that design is based on the “needs and interests” of the user, a philosophy called the user-centered design. In The Design of Everyday Things, Don Norman describes the psychology of users when they encounter products. Review by Sophie Wong, PhD student in Bioengineering
