Abstract

Official abstract text for this publication.

A presentation information generation device includes: a recommended position calculating unit that acquires ventilation equipment information indicating a state of ventilation equipment in a passenger car and outputs recommended position information of a passenger by using the ventilation equipment information; a presentation information generating unit that generates and outputs recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information output by the recommended position calculating unit; and a presentation information output unit that outputs, to a presentation device, the recommended position presenting information generated by the presentation information generating unit.

First claim

Opening claim text (preview).

The invention claimed is: 1 . A presentation information generation device comprising: recommended position calculating circuitry to acquire ventilation equipment information indicating a state of ventilation equipment in a passenger car and to output recommended position information of a passenger by using the ventilation equipment information; presentation information generating circuitry to generate and output recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information output by the recommended position calculating circuitry; presentation information output circuitry to output, to a presentation device including a display, a speaker, or a projector, the recommended position presenting information generated by the presentation information generating circuitry; and ventilation command circuitry to determine a piece of ventilation equipment based on the recommended position for the passenger and to control the determined piece of ventilation equipment to perform ventilation in accordance with at least the recommended position for the passenger and a calculated airflow. 2 . The presentation information generation device according to claim 1 , comprising passenger detection circuitry to detect the passenger in the passenger car, wherein the recommended position calculating circuitry outputs the recommended position information by further using passenger information indicating the passenger detected by the passenger detection circuitry. 3 . The presentation information generation device according to claim 1 , wherein the recommended position calculating circuitry acquires operation information indicating an operating situation of the passenger car or an operating state of the passenger car, and outputs the recommended position information by further using the operation information. 4 . The presentation information generation device according to claim 1 , wherein the recommended position calculating circuitry acquires sensor data indicating an air environment (a temperature distribution or a carbon dioxide concentration) in a car interior of the passenger car, and outputs the recommended position information by further using the sensor data. 5 . The presentation information generation device according to claim 1 , wherein the recommended position calculating circuitry acquires scheduled passenger information indicating a passenger who is scheduled to get on the passenger car at a next getting-on/off opportunity of the passenger car which is in operation, and outputs the recommended position information by further using the scheduled passenger information. 6 . The presentation information generation device according to claim 5 , further comprising scheduled passenger detection circuitry to detect the passenger who is scheduled to get on the passenger car at the next getting-on/off opportunity of the passenger car which is in operation, and to output the scheduled passenger information. 7 . The presentation information generation device according to claim 1 , wherein the ventilation equipment is disposed in such a way as to generate a plurality of air flows including at least an air flow between a ceiling central portion and a floor central portion in a car interior of the passenger car. 8 . The presentation information generation device according to claim 7 , wherein the recommended position calculating circuitry outputs air flow information indicating a state of an air flow in the passenger car together with the recommended position information. 9 . The presentation information generation device according to claim 8 , wherein the presentation information generating circuitry further acquires and outputs an air flow image indicating the state of the air flow in the passenger car by using the air flow information, and the presentation information output circuitry further outputs the air flow information to the presentation device. 10 . A presentation information generation method comprising: acquiring ventilation equipment information indicating a state of ventilation equipment in a passenger car and outputting recommended position information of a passenger by using the ventilation equipment information; generating and outputting recommended position presenting information indicating a recommended position of the passenger in the passenger car by using the recommended position information; outputting, to a presentation device including a display, a speaker, or a projector, the recommended position presenting information; determining a piece of ventilation equipment based on the recommended position for the passenger; and controlling the determined piece of ventilation equipment to perform ventilation in accordance with at least the recommended position for the passenger and a calculated airflow. 11 . The presentation information generation method according to claim 10 , further comprising detecting the passenger in the passenger car, and outputting the recommended position information by further using passenger information indicating the passenger detected. 12 . The presentation information generation method according to claim 10 , further comprising acquiring operation information indicating an operating situation of the passenger car or an operating state of the passenger car, and outputting the recommended position information by further using the operation information. 13 . The presentation information generation method according to claim 10 , further comprising acquiring sensor data indicating an air environment (a temperature distribution or a carbon dioxide concentration) in a car interior of the passenger car, and outputting the recommended position information by further using the sensor data. 14 . The presentation information generation method according to claim 10 , further comprising acquiring scheduled passenger information indicating a passenger who is scheduled to get on the passenger car at a next getting-on/off opportunity of the passenger car which is in operation, and outputting the recommended position information by further using the scheduled passenger information. 15 . The presentation information generation method according to claim 14 , further comprising detecting the passenger who is scheduled to get on the passenger car at the next getting-on/off opportunity of the passenger car which is in operation, and outputting the scheduled passenger information. 16 . The presentation information generation method according to claim 10 , wherein the ventilation equipment is disposed in such a way as to generate a plurality of air flows including at least an air flow between a ceiling central portion and a floor central portion in a car interior of the passenger car. 17 . The presentation information generation method according to claim 16 , further comprising outputting air flow information indicating a state of an air flow in the passenger car together with the recommended position information.
