Action presentation device, action presentation method, and recording medium

A behavior presentation method performed by a behavior presentation device that presents a behavior to a target user, the behavior presentation method comprising:

• a behavior list storage step for storing a behavior list in which behavior information indicating a possible behavior of a target group comprising a plurality of users or a single target user and at least either a cost indicating the difficulty of the behavior, or an evaluation value indicating an effect or a benefit produced if the behavior is performed are associated;
• a user information storage step for storing user information indicating a behavioral habit of the target group or the target user;
• a behavior information acquisition step for acquiring performed-behavior information indicating a behavior performed by the target group or the target user;
• an update step for updating the behavior list and the user information on the basis of the performed-behavior information;
• an extraction step for, on the basis of the user information, extracting behavior information for which at least either the cost or the evaluation value conforms with a predetermined evaluation criterion, from among the behavior information included in the behavior list;
• a generation step for generating presentation information for displaying the behavior information extracted;
• and
• a presentation step for presenting the presentation information to the target group or the target user.

A computer-readable recording medium storing a program causing a computer to function as:

• behavior list storage means that stores a behavior list in which behavior information indicating a possible behavior of a target group comprising a plurality of users or a single target user and at least either a cost indicating the difficulty of the behavior, or an evaluation value indicating an effect or a benefit produced if the behavior is performed are associated;
• user information storage means that stores user information indicating a behavioral habit of the target group or the target user;
• behavior information acquisition means that acquires performed-behavior information indicating a behavior performed by the target group or the target user;
• update means that updates the behavior list and the user information on the basis of the performed-behavior information;
• extraction means that, on the basis of the user information, extracts behavior information for which at least either the cost or the evaluation value conforms with a predetermined evaluation criterion, from among the behavior information included in the behavior list;
• generation means that generates presentation information for displaying the behavior information extracted;
• and
• presentation means that presents the presentation information to the target group or the target user.
