Abstract: Rotation of a DC motor (423) for vibration used for a head-mounted display (12) is stabilized.
A drive control system (100) includes a vibration section (42) including at least the DC motor (423) and provided in the HMD 12 including a display panel (38) disposed before eyes of a user when the user wears the HMD 12, and a motor control section (60) outputting a drive signal for controlling drive force that drives the vibration section (42), and the motor control section (60) outputs, in a predetermined startup period (T1), a first drive signal (DP1) causing the vibration section (42) to be driven by first drive force, and, after the startup period (T1) elapses, outputs a second drive signal (DP2) driving the vibration section (42) using second drive force smaller than the first drive force and including a plurality of single pulses to be intermittently output.
