Abstract: An evaluation processing method according to an embodiment is a method for generating evaluation information in an information processing system that lends a cabin of a mobile body. The method includes: registering a reservation of the cabin of the mobile body from user terminals; registering, after users use the cabin of the mobile body, an evaluation for the cabin from each of the user terminals in registration information by the corresponding user; and acquiring, from the registration information, an evaluation result of the cabin evaluated by each of the users having used the cabin, specifying, among the users, a first user immediately before a second user having performed an evaluation with an evaluation result different from others in chronological order, and generating evaluation information by registering an evaluation for the first user by a lender of the cabin in the registration information as the evaluation performed by the second user.

Abstract: An information processing system according to the present disclosure includes an owner terminal, a user terminal, and a management device. The owner terminal outputs vehicle information indicating whether at least a partial period of a lendable period is designated as a standing period in which a vehicle is not traveling. The user terminal outputs driver’s license information indicating whether a user is holding a driver’s license. The managing apparatus selects a vehicle at least a vehicle cabin of which is available to the user from a plurality of vehicles including a vehicle in a standing period in a lendable period, based on matching permission information, in which correspondences among whether vehicles are in respective standing periods, whether users are holding respective driver’s licenses, and whether vehicle lending is permitted are registered in advance, the vehicle information, and the driver’s license information, and outputs information indicating the selected vehicle.

Abstract: The information processing apparatus is an information processing apparatus in a system lending out vehicle cabins of mobile objects. The information processing apparatus includes a hardware processor functioning as a first output controller, a reception unit, and a second output controller. The first output controller serves to output first information indicating information on the vehicle cabins of the mobile objects in which at least a partial period of a standing period of the mobile objects is capable of being set as a lending period. The reception unit serves to receive an instruction by a user. The second output controller serves to output, on the basis of the instruction by the user, second information indicating that the vehicle cabin to be lent out to the user out of the vehicle cabins included in the first information is lendable.

Abstract: An information provision device that can provide useful information for the movement management of a moving mobile body. This information provision device has a movement trail processing unit for acquiring, from movement trail data for a reference mobile body that arrived at a prescribed destination by a prescribed time, a passing time at which the reference mobile body passed a prescribed waypoint and a movement trail display unit for displaying a diagram (520) indicating the intersection (movement trail data area (535)) between the waypoint and the passing time in a two-dimensional space having a time axis and space axis as the axes thereof.

Abstract: Disclosed are a sound generation system, an ultrasonic wave emitting device, and an ultrasonic wave emitting method which utilize the principle of parametric speakers (which uses the difference between frequencies of two ultrasonic waves) and which are capable of allowing target persons in a prescribed area to hear a sound only when a mobile body approaches said prescribed area. An alert system (10) has an ultrasonic wave emitting device (100) mounted on a mobile body (200), and an ultrasonic wave emitting device (300) permanently installed near an area (A101). The ultrasonic wave emitting device (300) emits a first ultrasonic wave towards an area at least including the aforementioned area (A101), and meanwhile, the ultrasonic wave emitting device (100) emits a second ultrasonic wave. The ultrasonic emitting device (100) forms the second ultrasonic wave by means of modulating the ultrasonic wave of frequency f1 with an audible signal.
