Abstract

An apparatus includes a laser projector and a laser beam ECU that is connected to a vehicle communication apparatus for communicating with an information center that provides a guidance service by an operator. According to an operation guidance by the operator, information indicating a switch to be operated is sent from the information center to the laser beam ECU through the vehicle communication apparatus. Then, the laser beam ECU identifies the switch to be operated based on the information and controls the laser projector to direct a laser beam to the switch to be operated.
