A multiple actuator drive control device for generating a sense of touch, comprising: an interface unit which receives an event-generation signal from a main processor; a parameter storage unit which stores event parameter groups that record event parameters necessary for event generation including channel-specific actuator form data and actuator-form-specific drive frequency data, for generating a sense of touch, and which selects and outputs one of the stored event parameter groups upon receipt of the event-generation signal; an event parameter analysis unit which analyses the event parameters of the event parameter group received from the parameter storage unit; a drive waveform generating unit which generates corresponding drive waveforms specific to each channel in accordance with the channel-specific actuator form and drive frequency data analyzed in the event parameter analysis unit; and an actuator drive unit which drives each of the channel-specific actuators in accordance with the drive waveform. According to the present invention, during the driving of a single actuator, use is made of the drive time, the drive strength and the drive direction by utilizing control parameters on a unfixed frequency, and hence the present invention has the advantageous effect of allowing a new sense of touch to be achieved by controlling actuators by adding control parameters without fixing the frequency. |
