Schneiderman's Eight Golden Rules of Interface Design are a set of principles that are used to improve the quality and effectiveness of user interfaces. Here they are, explained step by step:

1. **Strive for Consistency**: Consistent sequences of actions should be required in similar situations. Identical terminology should be used in prompts, menus, and help screens. Consistent commands should be employed throughout.

2. **Enable Frequent Users to Use Shortcuts**: As the frequency of use increases, so do the user's desires to reduce the number of interactions and to increase the pace of interaction. Abbreviations, function keys, hidden commands, and macro facilities are very helpful to an expert user.

3. **Offer Informative Feedback**: For every operator action, there should be some system feedback. For frequent and minor actions, the response can be modest, while for infrequent and major actions, the response should be more substantial.

4. **Design Dialog to Yield Closure**: Sequences of actions should be organized into groups with a beginning, middle, and end. Informative feedback at the completion of a group of actions gives the operators the satisfaction of accomplishment, a sense of relief, the signal to drop contingency plans and options from their minds, and an indication that the way is clear to prepare for the next group of actions.

5. **Offer Simple Error Handling**: As much as possible, design the system so the user cannot make a serious error. If an error is made, the system should be able to detect the error and offer simple, comprehensible mechanisms for handling the error.

6. **Permit Easy Reversal of Actions**: This feature relieves anxiety, since the user knows that errors can be undone; it thus encourages exploration of unfamiliar options. The units of reversibility may be a single action, a data entry, or a complete group of actions.

7. **Support Internal Locus of Control**: Experienced operators strongly desire the sense that they are in charge of the system and that the system responds to their actions. Design the system to make users the initiators of actions rather than the responders.

8. **Reduce Short-term Memory Load**: Human attention is limited, and humans are prone to errors if they have to remember too much information. Therefore, do not make users remember information from one part of the dialogue to another. Memory load can be reduced by techniques such as recognition rather than recall, visibility of object and action, and division of complex tasks into manageable subtasks.
