An information-processing apparatus (200) determines whether a stimulation generation unit (10, 11, 12) and a background virtual object (300) contact each other based on position and orientation information about the stimulation generation unit and position and orientation information about the background virtual object. If it is determined that the stimulation generation unit and the background virtual object contact each other, the information-processing apparatus determines whether the stimulation generation unit is included within an attention range (50, 55, 56). The information-processing apparatus generates operation setting information for controlling an operation of the stimulation generation unit according to a result of the determination and outputs the generated operation setting information to the stimulation generation unit.
