Abstract:
A projector projects a visible laser beam onto a region of a vehicle compartment. A control unit controls a direction of projecting the visible laser beam to provide information to at least one occupant in the compartment. The control unit expands the region of an object to which the visible laser beam is projected when the seatbelt has been fastened.
