Abstract:
A drowsiness prevention device includes a psychological state estimator and a controller. The psychological state estimator estimates a psychological state of an occupant, based on a state of the occupant detected by a detection device. The controller causes an output device to output a first warning and a second warning which are for alerting the occupant. The psychological state estimator estimates a first psychological state of the occupant which is before the first warning is output and a second psychological state of the occupant which is after the first warning is output. The controller determines details of a second warning, based on only the second psychological state or based on both the first psychological state and the second psychological state.
Abstract:
In an air-conditioning control apparatus, an input unit receives a detection signal from a sensor that detects the presence of an object at an air-supply port of an air-conditioning apparatus, and receives a recognition result from a recognition device that recognizes a change request for changing setting of the air-conditioning apparatus by a user. In a case where wind from the air-supply port is set at a first flow rate and the input unit receives the detection signal, the control unit outputs a first control signal for changing the first flow rate to a second flow rate different from the first flow rate for a predetermined time and then setting the wind from the air-supply port at the first flow rate again. In a case where the change request is issued, the control unit outputs a second control signal for causing the air-conditioning apparatus to adjust a property of wind from the air-supply port, based on the recognition result received by the input unit.
Abstract:
In a display control device, in accordance with speed limit information input from an input unit, a control unit senses change in a speed limit of a road where a vehicle travels and after that, in accordance with vehicle information input from the input unit, determines whether or not whether necessity to increase conspicuity of notification of the change in the speed limit. When it is determined that the necessity is high, a display unit is caused to switch display on a display medium from a first presentation image to a second presentation image that indicates a second speed limit by a first switching method. When it is determined that the necessity is not high, the display of the first presentation image is switched to the display of the second presentation image by a second switching method different from the first switching method.
Abstract:
A display control apparatus includes an input unit that receives recognition results of a change in an environment surrounding a vehicle, and a controller that generates and outputs a control signal to an image generating apparatus such that the image generating apparatus generates a first predetermined image representing a first presentation image on a display medium. The controller controls the image generating apparatus such that an image sharpness gradually lowers from the first presentation image to a second presentation image lower in image sharpness than the first presentation image on the display medium during a predetermined duration of time, based on the received recognition results.
Abstract:
A display control device includes a controller that, if an obtainer obtains first-segment speed limit information, controls a displayer so that it creates a first predetermined image, indicating a first-segment speed limit, and displays the first predetermined image on a display medium, and includes a determiner that, if second-segment length information is obtained after the first-segment speed limit information has been obtained, determines whether the second-segment length is shorter than a threshold. The controller makes a switchover from control under which the displayer creates the first predetermined image and displays it on the display medium to control under which the displayer creates a second predetermined image, indicating a second-segment speed limit, and displays the second predetermined image on the display medium in different control ways depending on whether the second-segment length is shorter than the threshold.
Abstract:
A display control device includes an obtainer and a controller. The obtainer obtains a detection accuracy of an object that exists in surroundings of a movable body. When the obtainer obtains a first detection accuracy, the controller controls an image generator so as to generate a first predetermined image that shows a first graphic having a predetermined shape and divided into n regions (n is an integer greater than or equal to 2). When the obtainer obtains a second detection accuracy that is lower than the first detection accuracy, the controller controls the image generator so as to generate a second predetermined image that shows a second graphic having a predetermined shape and undivided or divided into m regions (m is an integer that is greater than or equal to 2 and that is smaller than n).
