Description

System for reducing motion sickness of vehicle and information processing device Technical Field The present disclosure relates to a system for reducing motion sickness of a vehicle and an information processing apparatus. Background A method of sensing the state of an occupant in a vehicle to reduce motion sickness of the vehicle is known (refer to japanese patent application laid-open No. 2020-185378). In this method, sensing data is used to grasp the state of the occupant and control the vehicle to alleviate motion sickness. Disclosure of Invention In the above method, the state of motion sickness is predicted using data of all the passengers. Therefore, there is a need for improvement in accuracy in grasping the states of the multiple occupants, respectively. Further, since the same treatment is performed on all the passengers, treatments corresponding to the respective conditions cannot be provided. One aspect of the present disclosure preferably provides a system for mitigating vehicle motion sickness that is capable of providing appropriate treatment corresponding to respective motion sickness conditions of a plurality of users. One aspect of the present disclosure relates to a system for reducing motion sickness of a vehicle, which includes a sensor device configured to sense riding states of a plurality of users riding the vehicle in the vehicle, a plurality of communication terminals respectively allocated to the plurality of users, and an information processing device provided in the vehicle and configured to communicate with the plurality of communication terminals. The plurality of communication terminals are configured to store corona susceptibility data of users assigned to the communication terminals. The information processing device is configured to execute an motion sickness level estimation process in which the information processing device estimates motion sickness levels of the plurality of users using motion sickness data stored in the plurality of communication terminals and the riding conditions sensed by the sensor device, respectively, and a motion sickness reduction process in which the information processing device sets motion sickness reduction processes for the plurality of users based on the estimated motion sickness levels, respectively. According to the above configuration, it is possible to estimate the vignetting level of each of the plurality of users who take the vehicle based on the vignetting data of each user stored in the communication terminal. Accordingly, appropriate treatment corresponding to the motion sickness condition of each of the plurality of users can be provided. In one aspect of the present disclosure, the information processing apparatus may be configured to transmit the seating state of the user corresponding to each of the plurality of communication terminals in the motion sickness level estimation process, and to cause the plurality of communication terminals to predict the motion sickness level of the user corresponding to each of the plurality of communication terminals using the motion sickness easiness data and the seating state. According to the above configuration, the motion sickness level of each user can be estimated without providing personal information of the user to the information processing apparatus. Thus, personal information stored in the communication terminal can be protected. In one aspect of the present disclosure, the content providing device may be configured to provide a whole content shared by a plurality of users in the vehicle. The information processing apparatus may be configured to switch, as the motion blur reduction processing, a mode in which the content providing apparatus provides the entire content to the plurality of users to a mode in which the plurality of communication terminals provide the individual content to the plurality of users, respectively. According to the above configuration, it is possible to switch from a mode in which the same content is provided to a plurality of users to a mode in which individual content is provided to reduce motion sickness. Therefore, the content sharing device can have both a function of content sharing experience by a plurality of users and a function of motion sickness reduction. In one aspect of the present disclosure, the information processing apparatus may be configured to further perform a content determination process in which the information processing apparatus determines the entire content provided by the content providing apparatus based on a predetermined travel route of the vehicle and the corona susceptibility data stored in the plurality of communication terminals, respectively. According to the above configuration, the entire content can be selected according to the shape of the predetermined travel route, the ease of dizziness of each user, and the like. Accordingly, the content providing device can provide the entire content which is not likely to cause
