1. A vibration control apparatus for vibrating a vibration mechanism, the vibration control apparatus comprising:
a pseudo force sensory vibration data acquisition section that acquires pseudo force sensory vibration data descriptive of a pseudo force sensory vibration presenting a pseudo force sensation causing a user to feel a force of pulling in a specific direction;
a tactile sensory vibration data acquisition section that acquires tactile sensory vibration data descriptive of a tactile sensory vibration causing the user to feel a tactile sensation different from the pseudo force sensation;
a vibration control section that causes the vibration mechanism to generate a vibration based on the pseudo force sensory vibration data and the tactile sensory vibration data; and
a vibration adjustment section that adjusts at least one of the pseudo force sensory vibration and the tactile sensory vibration in accordance with one or more waveform parameters of the other of the at least one of the pseudo force sensory vibration and the tactile sensory vibration, such that the pseudo force sensory vibration and the tactile sensory vibration are simultaneously generated, wherein the vibration control section causes the vibration mechanism to generate the vibration based on a result of adjustment, wherein at least one of:
(i) the vibration adjustment section changes a frequency of the pseudo force sensory vibration in accordance with the tactile sensory vibration, and inverts a waveform of the pseudo force sensory vibration in a case where the frequency of the pseudo force sensory vibration is changed within a predetermined numerical value range, and
(ii) the vibration adjustment section adjusts a waveform of the tactile sensory vibration so as to reduce a bias of a vibration along a direction in which the pseudo force sensation is presented.
