Second journal entry due by 6pm, Wednesday, Oct 17
The journal entries should include your name, date, and a title. They should be good writing, but do not need to be formal writing!
This assignment is to observe yourself interacting with some man-made object, preferably something computerized (does not have to be a computer, per se). What was the object? What were you trying to accomplish (goal)? What did you do? What happened? How did you feel about the interaction? Which design models did you (or maybe more importantly, did not) see at play?
A brief overview of Shneiderman's Syntactic/Semantic Model.
Norman's Seven-Stage Model.
Four elements of good design:
01. Visibility
02. A Good Conceptual Model
03. Mapping
04. Feedback
Knowledge in the Head vs. Knowledge in the World.
Gulf of Execution. Gulf of Evaluation. Constraints. Affordances.
Ask yourself these questions when determining the function of a product:
Can you tell what actions are possible?
Is the mapping from intention to physical movement evident?
Can you tell what you need to do to perform your desired action?
Can you determine if the system is in the desired state?
Can you tell what state the system is in at any given moment?
