Abstract
The alert system includes a projection device, a display control unit, and a target object recognition unit. When a state changes from a state where a target object is not recognized by the target object recognition unit to a state where a target object is recognized by the target object recognition unit, the display control unit causes the projection device to output an alert display on a front window such that the length of the alert display is gradually shortened toward a position where a direction from an operator to the target object intersects with a front window.
