How many Normans principles are there?
To help determine the answers to the seven questions, Norman has devised a list of seven fundamental design principles. Each principle can be applied as a special design strategy to make products efficient and effective to use.
What does HCI stand for?
Human-computer interaction (HCI) is a multidisciplinary field of study focusing on the design of computer technology and, in particular, the interaction between humans (the users) and computers. While initially concerned with computers, HCI has since expanded to cover almost all forms of information technology design.

Designing “consistent interfaces” means using the same design patterns and the same sequences of actions for similar situations.
What is Don Norman’s mapping?
Mapping – This refers to the relationship between controls and their effects in the world. Nearly all artifacts need some kind of mapping between controls and effects, whether it is a flashlight, car, power plant, or cockpit.
What does Norman mean when he talks about discoverability?
According to Norman, the characteristics of good design are discoverability and understanding. Discoverability refers to being able to figure out what actions are possible, so you know where and how these actions can be performed. In other words, they’re not so hidden that no one can understand what your product does.
