Haptic Feedback Latency

Layer 05 // Chronology

Modern devices use Linear Resonant Actuators (LRAs) to provide sharp, precise physical feedback. However, these actuators have a physical spin-up time (~10-15ms).

If a visual button press animation is instantaneous, but the haptic tap takes 15ms to trigger, the brain perceives them as disconnected events. UI animations must be delayed slightly to synchronize with the physical motor.
