Why use a linear motor (LRA) instead of ERM in a controller?

LRAs start and stop far faster than ERM rotating-mass motors, enabling crisp, frequency-controlled HD effects instead of a single buzzing intensity.

What makes controller haptics 'good'?

Low latency, wide dynamic range, fast transients, and effects that map meaningfully to in-game events — exactly what HD haptic systems like RA2H deliver.

LRA vs ERM in game controllers: why linear motors win

Why linear motors win

Draft outline — full copy to be written. Covers ERM limitations, LRA advantages, HD vibration definition, and how SimpleHaptics drives LRAs with its own IC + RA2H.
