Hey!I'm doing some research on the haptic feedback with some Apple devices, and I'm wondering what the haptic sharpness (https://developer.apple.com/documentation/corehaptics/chhapticevent/parameterid/3114596-hapticsharpness) physically map to?While I understand that the intensity (https://developer.apple.com/documentation/corehaptics/chhapticevent/parameterid/3114595-hapticintensity) maps to amplitude of the vibration, the physical attribute of the sharpness is not directly stated in the documentation. I'm wondering if it's the frequency of the vibration or is it waveform ( see examples of waveform here: https://www.precisionmicrodrives.com/haptic-feedback/haptic-evaluation-kit-tutorial-building-your-own-vibration-alerts/ )Thank you very much & have a nice day!Kevin
