Abstract: An action-sequence generation unit of an information presentation device generates, based on an action log representing a target action of a user and an action history of the user, an action sequence representing a sequence of actions including the target action. A permission-level calculation unit calculates, based on the action log and a permission log, about the actions, a permission level representing a difference between a time period when the actions included in the action log were performed and a time period when the actions included in the permission log are permitted. An action specifying unit specifies, based on the action sequence and the permission level, out of the actions in the action sequence, an action, the permission level of which is equal to or larger than a threshold concerning the permission level, as a trigger action among the actions included in the action sequence.

Abstract: A state acquisition unit of an information presentation device acquires a state of a user.

Then, an information output unit outputs the action acquired by the action information acquisition unit.
