Overview
(Talk more about finger / stylus split philosophy)
General Principles
- All modifications are saved instantenously, there should never be a save command
- Make sure users can't make interface operation errors, or that the effects are easily reversible, instead of just notifying them us the potential consequences of their actions.
- When you open a document you should be returned to the place where you were working when you last closed or save it (this is our concepts of sessions).
- Label buttons with adjectives, which describe the state of the object affected
- Designers should seek an efficient monotonous solution to gain benefits, including ease of learning, simplicity of implementation, minimization of documentation, and lowered maintenance costs.
- Whenever you find yourself specifying an error message, please stop; then redesign the interface so that the condition that generated the error message doesn't arise.
- Is the user gets no utility from a process, there is no reason to tell them that it is happening.
