Abstract: A patrol robot includes: an imaging device that captures an image; a notification device that notifies an event increasing an industrial accident risk of a worker; and a control device that controls an overall operation of the patrol robot. The control device includes a movement control unit that controls the patrol robot to move in a plant based on a patrol route for patrolling a work area in the plant, a detection unit that processes moving image data captured by the imaging device after start of patrol, during the patrol, thereby detecting the event increasing the industrial accident risk of a worker, and a notification instruction unit that, when the event increasing the industrial accident risk of a worker is detected, performs a notification via the notification device to prompt reduction of the industrial accident risk.

Abstract: This driving assistance system comprises: an alarming object recognition unit that recognizes a participant who has a high degree of influence on safe driving as an alarming object; a display object setting unit that sets, as a display object, a preceding vehicle 2a recognized as the alarming object; a display control unit that emphasizes the presence of the preceding vehicle 2a set as the display object, on a front glass 51; and a driver recognition detection device that detects the presence or absence of the driver's recognition of surrounding traffic participants. The display object setting unit cancels the setting of the preceding vehicle 2a as the display object when the driver's recognition of the preceding vehicle 2a set as the display object is detected, and thereafter sets the preceding vehicle 2a as the display object again when the degree of influence of the preceding vehicle 2a increases.

Abstract: A drive assistance system includes a display object configurator that sets, as a display object or a non-display object, each of traffic participants recognized as alert objects from among nearby traffic participants, and a display controller that performs highlight image processing for highlighting the presence of the display object. When a first traffic participant set as the display object and a second traffic participant set as the non-display object are present in the vicinity of the subject vehicle and recognized as alert objects with the recognition of the first traffic participant by the driver being detected while the highlight image processing is performed, the display object configurator compares the degrees of influence of the first and second traffic participants, sets, as the display object, one of the first and second traffic participants designated on the basis of a result of the comparison, and sets the other as the non-display object.

Abstract: To reduce a chance that the driver overlooks the object that should be seen, a visual guidance device for guiding a visual line of a driver of the vehicle to an object existing ahead of the vehicle includes an object recognition unit for recognizing the object, and a display control unit for causing the display device to display the visual guidance virtual image for guiding the driver's visual line to a position corresponding to the object recognized by the object recognition unit on a windshield of the vehicle. The display control unit sets a length of the visual guidance virtual image to be displayed by the display device in the vehicle width direction to a length in accordance with a status of the object existing ahead of the vehicle.

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.

Abstract: An information display device includes a display unit configured to display information about an object such that the information about the object at least partially overlaps with forward view of a user, and a controller configured to control display of the display unit. The controller is configured to estimate or acquire a prospective moving direction of the object, acquire a sight-line frequency representing a frequency with which a sight-line of the user is directed to the object within a prescribed period, determine whether the sight-line frequency is equal to or more than a prescribed frequency threshold, and cause the display unit to display the prospective moving direction of the object at least on condition that the controller determines that the sight-line frequency is less than the frequency threshold.

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.
