Abstract
A visible laser beam projection system determines a target point of position to which a visible laser beam is to be projected, a start point and a trajectory from the start point and the target point based on data of conditions inside and outside of a vehicle. The system starts projecting the visible laser beam from the start point, moves the visible laser beam while it is being projected along the trajectory and stops the projection of the visible laser beam. The start point, target point and the trajectory may be changed depending on contents to be indicated.
