Extended reality, consisting of virtual reality and artificial intelligence, is increasingly identified as an effective educational technology because of its immersive and experiential nature. Immersive environments actualize the Ciceronian technique of loci, which organized knowledge into memory palaces in which “imagines agentes,” active (today we would say interactive) images effective for a mnemotechnical purpose, were inserted. The enjoyment of virtual environments set up to construct the learner’s knowledge is only a first mode of use of this new educational tool: in fact, the experience can evolve and become even more interesting if reworking or even creating immersive content is added to it. Generative artificial intelligence can be used to create and embed multimedia content in virtual environments designed for teaching. Text to speech, data ingestion, machine translation, conversational prompts, multimodal content generation-these are all features enabled by artificial intelligence that becomes extremely interesting when applied to interactive immersive environments.
