9 Partial Heuristic Analysis What am I supposed to do now? Chunk info. Reversible Actions. One click access to help, menus, exit. Logical order. Clear button symbols or labels. Consistent cues. Buttons easily findable. Help and instructions easily accessible. Where Am I? Where can I go? Color must not be the sole conveyer of information. Multiple navigation modes. Icons always paired with text labels, easily distinguished, simple in design, borderless, and not color dependent. Make things visible. Place knowledge in the world. User's conceptual model matches system model Non-serifed standard text. Kruse & Keil PearrowNielsenNorman
