The present invention provides an operation control device for preventing an incorrect operation during a change in a holding pattern of an input device. The operation control device is an operation control device which controls an operation inputted into a grippable input device by a user, including: a grip state detection unit (103) configured to detect a first grip state which is a state in which the user is holding the input device; an orientation detection unit (106) configured to detect an orientation of the input device; a holding pattern determination unit (1107) configured to determine whether or not the user is changing a holding pattern of the input device by determining whether or not a combination of the first grip state and the orientation corresponds to a predetermined combination; and an operation control unit (108) configured to invalidate the operation inputted into the input device when it is determined that the user is changing a holding pattern of the input device and configured to validate the operation inputted into the input device when it is determined that the user is not changing a holding pattern of the input device.
