Require attention to be earned.
Do not introduce signals that do not justify their cognitive cost.
Contents 1. Human Cognition & Behavior 1. Attention & Focus
What users can attend to at any moment.
First, ask yourself
“Does your system occupy users’ attention only when it directly advances their goals?”
Mission statement
Ensure users attend to what matters by prioritizing and timing signals appropriately, free from distraction or visual noise.
Key heuristics Attention & Focus
- Attention must be justified by value.
- What matters now must dominate perception.
- Focus may be broken only to prevent greater harm.
- Attention must support forward movement.
- Primary tasks must come first unless background systems become crucial to outcomes.
- Task context must remain stable across interaction.
- Work resumption must be immediate and predictable.
- Motion must clarify state change.
- Calm must serve as a performance condition, not as decoration.
Executive brief
The system must earn users’ attention only when it clearly advances their goals.
Core questions Attention & Focus
“Does the system earn users’ attention when it asks for it?”
“Are attention demands justified, clear, and timely?”
Focus areas
Proportion-aware
“Is this interruption justified?”
“Is the demand on attention proportional to its value or risk?”
Action-aware
“What must the user notice immediately? What can wait?”
“Does the signal guide action, or just announce itself?”
Context-aware
“Is attention aligned with the user’s current task or goals?”
“Does timing respect what the user is doing rather than disrupt it?”
AI-aware
“Why is this being surfaced now? What happens if it is ignored?”
“Is this guidance or attention capture?”
UX directives Attention & Focus
Prioritize relevance over visibility.
Emphasize what matters now and deliberately de-emphasize everything else.
Interrupt only when necessary.
Break focus solely when inaction would cause greater harm than interruption.
Guide attention toward action.
Use emphasis to support task progress, not novelty or decoration.
Enforce foreground–background discipline.
Keep background activity unobtrusive unless user outcomes depend on awareness.
Preserve task continuity.
Ensure users can always resume without questioning their previous state.
Design explicitly for re-entry.
Assume interruption and make recovery fast, clear, and predictable.
Use motion to clarify change.
Apply animated transitions only to explain state transitions, not to attract attention.
Treat calm as a functional requirement.
Use silence, restraint, and visual economy as active design tools.
Executive summary
- Attention is a scarce resource that must be justified, not claimed.
- Responsibility for focus lies with the system, not the user.
- User attention must be earned by the system through relevance.
- The system is responsible for protecting user focus and task continuity.
- Any interruption or signal must justify its cost by directly advancing users’ work.
- Attention & Focus succeeds when users progress without distraction and resume without disorientation.
Success indicators
- The primary task is unmistakable.
- Visual and behavioral hierarchy makes priorities clear.
- Competing signals are restrained.
- Interruptions occur only when justified and timely.
- Users can easily resume their task after interruption.
One-line summary
Before users can act effectively, they must clearly see what deserves their attention right now.
