The interfaces should be easy to understand, learn, and efficient over time.
The ideal humane interface reduces the interface component of a user's work to pure habituation.
A well-designed human interface should not be split into beginner and expert modes. Instead, think of the interface as a beginner-to-expert journey.
The learning phase of working with any professional interface requires conscious attention. Simplicity, clarity of function, and the visibility of a user interface helps beginners learn.
The expert phase is characterized by fast unconscious use.
