Knowing What to Do: Constraints, Discoverability, and Feedback
APA: Norman, D. The design of everyday things. New York, NY: Basic Books.
4 Types of constraints
Physical
-
Rely on properties of the physical world for their operations, no special training required. (Norman, (2012).
-
-
-
Cultural norms, conventions, and standards

"Affordances, signifiers, mappings and constraints can simplify our encounters with every day life (Norman, 2012, p. 132)".
-
The lack of clear communication among the people and organizations constructing parts of a system is the most common cause of complicated, confusing designs.
"A usable design starts with careful observation of how the tasks being supported are actually performed, followed by a design process that results in a good fit to the actual ways the tasks get performed (Norman, 2012, p. 137)".
Activity-centered controls are the way to go if the activities are carefully selected to match actual requirements.

Reflection: This chapter hit on a lot of good points. I think my favorite point was how culture tends to impact design. It can be a constraint, but it can also help to drive design while impacting conventions. Often times, as designers, i think we tend to create a one size fits all training approach. I like that Norman has opened my eyes to creating training that is aware of constraints and how I can use them to my advantage in design. I also like how feedback seems to be a continuous theme he brings back. This is so important for us as designers as it should be used to improve design.
