Nowadays, training on the Intraosseous Insertion (IO), a critical life-saving procedure in the medical field, is a significant challenge. Mastering this technique, which requires high psychomotor precision and knowledge, is necessary to preserve the patient’s life. The aim of this thesis work was the development of a virtual assistant based on the open-source Rasa framework, to improve the training of healthcare professionals and paramedics in the IO procedure. The main objective was to provide an interactive and effective learning experience through the use of a conversational agent specifically designed to understand users’ requests and provide contextualized instructions, suggestions and feedback during the execution of the procedure.
