HCI Design Heuristics
The Eight Golden Rules, Shneidermann, 1998):
- Strive for consistency
sequens of actions in similar situations, identical terminologi in menus, prompts etc.,
- Enable frequent users to use shortcuts
- Offer informative feedback
for every user actions there should be system feedback.
- Design dialogs to yield closure
sequences of actions should be organized into groups with a beginning, middle, and end.
- Offer error prevention and simple error handling
to prevent serious errors (e.g prefer menu selection to form fillin), minimize retyping forms,..
- Permit easy reversal of actions
- Support internal locus control
operators should be in charge (no surprises, difficulty to obtain information,..)
- Reduce short-term memory load
human short-term memory handles 7 +-2 chunks.
