Abstract
A method for quantifying fidelity of a haptic signal may include receiving a response signal indicative of a vibrational response of a vibrational transducer to a haptic playback waveform driven to the vibrational transducer, perceptually filtering the response signal to obtain human haptic-perceptible components of the response signal, and quantifying fidelity of the haptic playback waveform based on at least one quantitative characteristic of the human haptic-perceptible components of the response signal.
