Memory & Recall
Working Memory
Temporary storage for information needed to complete a task.
Takeaways
- 1
Never force users to remember data from a previous screen.
- 2
Keep summaries visible during multi-step tasks.
- 3
Breadcrumbs and inline references reduce reorientation cost.
Origins
Working memory holds the small amount of information needed for the task at hand. It empties quickly under distraction and does not tolerate unnecessary recall demands.
Interfaces should function as external memory, not memory tests.
Design Applications
- Show cart and selection summaries throughout checkout.
- Repeat key inputs on confirmation steps.
- Use persistent side panels for reference data in complex tools.
