Abstract: An alert system includes a display device, a display control unit, and a target recognition unit. The display control unit: when the number of targets recognized by the target recognition unit is equal to or more than an upper limit number, sets a display range of a surrounding icon as a whole circular area; and in a state where the number of targets is equal to or more than the upper limit number and the display range of the surrounding icon is set as the whole circular area, when the number of targets increases, reduces the size of the surrounding icon.

Abstract: The virtual image display device comprises a surrounding state recognizer that acquires a travel direction distance and a lateral direction distance to an object, and a display controller that displays object icon images I1, I2 in a screen 51. The display controller is capable of switching between displaying an image in a normal mode, in which the display positions of the images I1, I2 move closer in a lateral direction to a lateral reference line L1 as the travel direction distance increases, and move farther away in a screen vertical direction from a screen bottom line L2 as the travel direction distance increases, and displaying the image in a magnification mode, in which a vertical scale, which is the ratio of the distance between the line L2 and the display positions in the screen vertical direction to the orientation direction distance, is larger than in the normal display mode.

The attention calling unit outputs the visual display in the mode adapted to the risk value of the object.

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.
