Abstract: The content output device includes an information acquisition unit, a content generation unit and an output unit. The information acquisition unit acquires driving state information which is information related to a current driving state of a vehicle. The content generation unit acquires one or more content elements corresponding to a trigger condition, from among a plurality of content elements combinable with each other, when the driving state information satisfies the trigger condition, and generates an output content using the acquired content elements. The output unit outputs the output content.
