My Interface Design Principles
by Tom Carroll
I did some work on putting together a new interface design for an application. So, I thought I would provide my guiding principles.
- “Information becomes the interface”, Edward Tufte in Visual Explanations p.142.
- “OODA Loop” (Observation, Orientation, Decision, Action) By Col John Boyd, USAF (Ret).
- Information displays should strive to be no wider than 16 choices and 2 levels deep.
- Base change on real observed behavior. The qualitative can not eliminate the quantitative
- To some degree the interface has to be stupid simple. The antithesis to this principle is demonstrated by some large ERP software vendors.
- Do as much work beyond view of the customer as possible.
- Icons are Iconic or they are not valuable.
- Visual oriented communication occurs a faster rate and results in increased short term retention
- Make help always available and obvious
- Continuity Continuity Continuity
