Motion and Haptics That Feel Natural
Use easing that matches physics: ease-out for arrivals, ease-in for departures, and gentle overshoot to imply elasticity. Direction should support meaning—left to right for forward progress, vertical motion for layering—so users instinctively parse structure and flow.
Motion and Haptics That Feel Natural
Keep microinteractions short and crisp. Most state changes feel great at 150–250 milliseconds, while confirmations can linger slightly longer. Too slow feels heavy; too fast seems broken. Prioritize snappiness, especially on older devices and in low-power situations.
