Abstract:
The invention relates to a method for generating haptic coefficients associated with an audiovisual document. Initially, data is extracted from an audio and/or video track and is used to calculate at least one first group of haptic coefficients from an autoregressive model applied to the read data. These haptic coefficients are designed to program a filter supplying at the output the control parameters for controlling at least one haptic actuator. Then, a “haptic” sequence of the audiovisual document is determined and calculated haptic parameters are associated with the determined sequence. In this manner, the haptic parameters enabling the control of one or more actuators are easily calculated and easily reproducible. Advantageously, the data used for the calculation is extracted from the selected sequence.
