Abstract
A method of generating a haptic sensation comprising: determining an initial estimate of a filter to be applied to a respective signal input to each transducer; defining a model of the system; calculating the vibration of the member as an output of the model of the system; calculating a reference error value for the output of the model; determining changed parameter values of the parameters of the model; recalculating the error value for the output of the model; comparing the recalculated error value with the reference error value; setting the recalculated error value as the reference error value, setting the changed parameter values as the model parameters, and repeating the above steps, or outputting the model parameters; generating a new filter using the output model parameters; and applying the new filters to respective input signals applied to each transducer to generate vibration within the member to provide the haptic sensation.
