Synchronised Sensory Feedback
The User Reality: Distress is often triggered by "The Split-Attention Effect," where sensory cues are contradictory - for example, a visual event that does not perfectly synchronise with its audio or haptic feedback. This mismatch forces the brain to expend excessive energy trying to integrate conflicting signals.
Research:
The Openality Standard
All visual, auditory, and haptic cues must be "redundant and aligned" to reinforce a single interaction, ensuring that if one channel is blocked or suppressed, the message remains clear.
- Constraint: Sensory cues must not be contradictory; all feedback must be synchronised to avoid perceptual friction.
- Requirement: Feedback must be repeated across modalities (e.g., a button glows, clicks, and vibrates simultaneously) to create a fail-safe interface.
Core Behaviours
Multimodal Consistency: Ensuring that all sensory feedback is consistent and reinforces the same message, reducing cognitive load and preventing distress caused by conflicting cues.
Primary Interaction Patterns
Global Visual Intensity Controls: Allowing users to adjust the intensity of visual feedback while maintaining synchronisation with audio and haptic cues, ensuring a cohesive sensory experience that can be tailored to individual needs.
