Content playback system, information processing apparatus, and content playback controlling application

A content playback system, comprising:

• a wearable device;
• and
• an information processing apparatus that includes a control circuit that executes a content playback controlling application that includes
• a database generator that associates a registration-use detection value detected by a sensor section included in the wearable device worn by a user with an environment state to be provided to the user when the registration-use detection value is detected, and registers the associated registration-use detection value and environment state,
• a matching section that checks a new detection value detected by the sensor section against the registered registration-use detection value to perform matching, and determines whether a difference between the new detection value and the registration-use detection value is less than or equal to a matching threshold, and
• a content controller that
• generates, when the difference is determined to be less than or equal to the matching threshold, a cue on a basis of the environment state registered in association with the registration-use detection value, the cue being used by a content provision application providing content to select the content,
• outputs the cue to the content provision application, and
• causes the content provision application to select the content on a basis of the cue to cause the content to be played back.

An information processing apparatus, comprising

• a control circuit that executes a content playback controlling application that includes
• a user state estimator that estimates a user state of a user who is wearing a wearable device,
• an environment estimator that estimates, on a basis of the user state, an environment state to be provided to the user, and
• a content controller that
• generates, on a basis of the environment state, a cue used by a content provision application providing content to select the content,
• outputs the cue to the content provision application, and
• causes the content provision application to select the content on a basis of the cue to cause the content to be played back.

A content playback controlling application that causes a control circuit of an information processing apparatus to operate as

• a user state estimator that estimates a user state of a user who is wearing a wearable device,
• an environment estimator that estimates, on a basis of the user state, an environment state to be provided to the user, and
• a content controller that
• generates, on a basis of the environment state, a cue used by a content provision application providing content to select the content,
• outputs the cue to the content provision application, and
• causes the content provision application to select the content on a basis of the cue to cause the content to be played back.
