Critical state needs a change cue more salient than everyday noise
Aliases: critical alert · salience · state change · attention cue
What it is
Salient critical-state change uses a more noticeable visual, auditory, or haptic change than ordinary interface updates when low health, weapon failure, objective turns, a downed teammate, or environmental danger will alter an immediate decision. The emphasis is on change rather than permanent highlighting: players need to know that something worth acting on happened now.
Why it happens
Stable HUD easily recedes into background, and permanently conspicuous elements become habituated. If a critical state appears only as a small numerical shift, it can be missed while aim, movement, or communication occupies attention. A brief, discriminable change captures attention and binds transition to corrective action, crossing the noise threshold of the current task.
Where it stops holding
Salience is scarce. Flashing, alarms, or vibration for every resource movement or enemy appearance creates alert fatigue and masks genuine danger. Players also differ in sensitivity to contrast, flashes, and volume. Cues should vary with consequence, urgency, and actionability instead of treating all messages alike.
Applying it
- Define distinct salience levels for critical, important, and ordinary updates, connecting each cue to an actionable next step.
- Combine brief form, colour, motion, sound, or haptics; offer reduced flashes and audio, avoiding one intense stimulus as the only signal.
- Verification: test detection and reaction time for critical transitions under real load, while tracking false alerts, ignoring, and discomfort to adjust thresholds and concurrency.
