Abstract: Provided are a disease-condition assessment device for being capable of assessing an epileptic condition of a subject, a disease-condition assessment method, a program for disease-condition assessment device, and a disease-condition assessment system. The gaze data indicating a subject's gazing point measured when the subject is driving a vehicle is acquired, the driving-characteristic data indicating driving characteristics of the subject for the vehicle is acquired), and the epileptic condition of the subject is assessed depending on the relationship between the gaze data and the driving-characteristic data.

Abstract: Provided are a disease-condition assessment device for assessing a disease condition of a subject, a disease-condition assessment method, a program for disease-condition assessment device, and a disease-condition assessment system. The operation-quantity data that the subject operates the vehicle is acquired, the operation-related data in the components of a predetermined frequency range is calculated from the operation-quantity data, the operation value that quantifies the operation-related data is calculated from the operation-related data, and the disease condition of the subject is assessed depending on the operation value.

Abstract: Provided are a disease-condition assessment device for assessing a disease condition of a subject, a disease-condition assessment method, a program for disease-condition assessment device, and a disease-condition assessment system. The disease condition assessment device acquires a data of a seat pressure distribution on a seating surface where a subject operating a vehicle is seated, calculates a center position depending on the seat pressure distribution, calculates a degree of laterality in the seat pressure distribution based on the center position, and assesses a disease condition of the subject depending on the degree of laterality.

Abstract: A stair climbing vehicle that is able to stably climb stairs is provided. In order to keep the balance of the stair climbing vehicle at the time of climbing the stairs, the ratio between a gravity center moving control gain for the stair climbing vehicle and a turning control gain for first wheels and second wheels is changed by controlling the rotation of a first motor of each first turning actuator. Thus, it is possible to slightly turn the first wheels and the second wheels based on the posture of an occupant seated on the stair climbing vehicle when the occupant climbs the stairs with the stair climbing vehicle, thereby preventing the posture of the occupant from being unstable. Thus, the stair climbing vehicle is able to stably climb the stairs.
