Abstract: A display control device for controlling a display position of a virtual image displayed and superimposed on a foreground in a vehicle (A), includes: an information acquisition unit for acquiring state information of the vehicle and extracting attitude change information and vibration information of the vehicle from the state information; a position correction unit for correcting a displacement of the display position of the virtual image with respect to the foreground caused by the attitude change of the vehicle, based on the attitude change information; a rough road determination unit for determining whether a road is a rough road, the road on which the vehicle is traveling or scheduled to travel, based on the vibration information; and a correction suppression unit for suppressing a correction control of the display position executed by the position correction unit and continuing to display the virtual image, based on a rough road determination.

Abstract: In a biological information detection device, a frequency characteristic indicating a relation between a frequency and an intensity is acquired with respect to each of a plurality of biological signals input respectively from a plurality of biological activity sensors arranged at a plurality of positions different from each other to detect a biological activity of a person. A synthetic frequency characteristic indicating the relation between the frequency and the intensity is obtained by synthesizing a plurality of frequency characteristics acquired from the plurality of biological signals. Biological information on the biological activity is calculated based on the synthetic frequency characteristic.

Abstract: A display control device controls display of a virtual image which is superimposed on foreground of a vehicle by projection of a display light image from an optical unit to a projection area. The display control device sets a projection position of the display light image which is projected in the projection area on the basis of a relative position of a superimposition object on which the virtual image is superimposed, obtains a measurement information from one vehicle height sensor measuring a displacement in a vertical direction occurring in the vehicle, obtains a gradient information indicating a gradient of a road on which the vehicle travels on the basis of three-dimensional map data, and corrects the projection position of the display light image on the basis of the measurement information and the gradient information.

Abstract: A display control unit controls a virtual image display device that superimposes a virtual image on a foreground of an occupant of the vehicle. The display control unit acquires posture information indicating a change in posture of the vehicle based on a signal of a posture sensor attached to the vehicle. The display control unit acquires driving force information indicating a state of a driving force acting on the vehicle. The display control unit determines that the vehicle is traveling on a rough road when the change in posture indicated by the posture information exceeds a threshold value in a state where the driving force indicated by the driving force information is stable.

Abstract: An orientation detection device obtains a detection information of a sensor that detects a displacement in the vertical direction occurring in the vehicle, computes a pitch angle of the vehicle on the basis of the detection information, obtains a gradient information indicating a gradient of a road on which the vehicle travels, and corrects a correlation between the detection information used in computation and the pitch angle on the basis of the gradient information.
