1. A control device comprising
a control section configured to vibrate a contact region in a case where it is determined that an operation is performed on an input section by a target object coming into contact with the contact region, the input section having the contact region touched by the target object,
wherein the control section adjusts a displacement rise time as a control parameter for performing control of vibrating the contact region, the displacement rise time being a required time from a first time when displacement of the contact region caused by vibration becomes a first displacement within a first predetermined range from a local minimum value of the displacement to a second time when the displacement of the contact region caused by the vibration becomes a second displacement within a second predetermined range from a local maximum value of the displacement,
wherein the control section adjusts an acceleration peak-to-peak value to be a larger value when the displacement rise time is adjusted to be a smaller value, and adjusts the acceleration peak-to-peak value to be a smaller value when the displacement rise time is adjusted to be a larger value,
wherein the control section controls an acceleration time and the displacement rise time as control parameters and the acceleration time is a time period from when acceleration applied by vibration to the contact region becomes a first rate value based on a first extreme value of the acceleration for a first time to when the acceleration becomes a second rate value based on a second extreme value of the acceleration for a last time, and
wherein the control section adjusts the acceleration time in such a manner that an acceleration time becomes less than a sixth criterion value in a case of adjusting the displacement rise time in such a manner that the displacement rise time becomes less than a second criterion value, the second criterion value is the displacement rise time when the vibration of the contact region is imperceptible, and the sixth criterion value is the acceleration time when the vibration of the contact region is imperceptible.
