A content selection device, comprising:

• a processor;
• a memory;
• a display;
• and a transmitter/receiver configured to execute operations, including
• acquiring a plurality of images related to intensities of at least one emotion, wherein the intensities are based on determined values of selectable criteria, which include arousal level, emotional valence, tension, complexity, and stress;
• displaying the plurality of images in a selectable manner in a display, wherein the displaying of the plurality of images includes displaying a plurality of images related to intensities of a first emotion;
• acquiring an intensity of the first emotion to which an image that the user has selected from the plurality of images related to intensities of the first emotion, and designating the acquired intensity as a current emotional state that indicates a user's current emotional state;
• measuring a selection time lasting from when the plurality of images are displayed until the image is selected by the user;
• in response to the selection, displaying, in a selectable manner, a second plurality of images related to intensities of a second emotion only when the measured selection time is shorter than or equal to a predetermined time, the second emotion differing from the first emotion;
• in response to a selection of the second emotion, acquiring a target emotional state that indicates an emotional state that the user has set as a target;
• determining a content to be used to change the current emotional state to the target emotional state;
• and
• outputting the content.

A non-transitory computer-readable recording medium that stores a content selection program that causes a computer to perform:

• acquiring a plurality of images related to intensities of at least one emotion, wherein the intensities are based on determined values of selectable criteria, which include arousal level, emotional valence, tension, complexity, and stress;
• displaying the plurality of images in a selectable manner in a display, wherein the displaying of the plurality of images includes displaying a plurality of images related to intensities of a first emotion;
• acquiring an intensity of the first emotion to which an image that a user has selected from the plurality of images related to intensities of the first emotion, and designating the acquired intensity as a current emotional state that indicates a user's current emotional state;
• measuring a selection time lasting from when the plurality of images are displayed until the image is selected by the user;
• in response to the selection, displaying, in a selectable manner, a second plurality of images related to intensities of a second emotion only when the measured selection time is shorter than or equal to a predetermined time, the second emotion differing from the first emotion;
• in response to a selection of the second emotion, acquiring a target emotional state that indicates an emotional state that the user has set as a target;
• determining a content to be used to change the current emotional state to the target emotional state;
