Abstract: The present technology relates to an information processing device and an information processing method that enable output of information using a more optimal output modal. Provided is an information processing device including a processing unit configured to perform processes of: acquiring apparatus information regarding an output modal for each electronic apparatus; selecting an electronic apparatus having an output modal that outputs information from among a plurality of electronic apparatuses on the basis of the acquired apparatus information; and outputting the information from an output modal of the selected electronic apparatus. The present technology can be applied to, for example, electronic apparatuses such as information apparatuses, video apparatuses, audio apparatuses, or household electrical appliances.
