Abstract
A haptic calibration device comprises a signal generator configured to receive the subjective force value and the force location from a subjective magnitude input device. The signal generator also receives from at least one of a plurality of haptic sensors a sensor voltage value, with the at least one of the plurality of haptic sensors corresponding to the force location. The signal generator stores the subjective force value and the corresponding sensor voltage value in a data store. The signal generator generates a calibration curve indicating a correspondence between subjective force values and sensor voltage values for the location where the subjective force was experienced using the data from the data store, wherein the calibration curve is used to calibrate a haptic feedback device.
