The COVID-19 pandemic reveals that digital health interventions will be indispensable to care for special patient groups in the long-term successfully. Current research focuses on embodied conversational agents (ECAs) that promise patient support by emulating interpersonal communication. Against the background of high relapse rates in obesity care and significant costs for the healthcare systems, this work presents a prototype of an ECA as a virtual coach for morbidly obese patients, along with a first evaluation of its acceptability from a patient’s perspective. The results indicate that a virtual coach meets the patients' needs and motivate further investigations of the technological concept.
