Zeynep Erol – Sofra – 2026 #1

by Zeynep Erol

Sofra is a culturally adaptive conversational agent that supports dietary behaviour change by understanding how people relate to food. Developed within the EU SWITCH project, it builds a personal food culture from photos, mind maps, and voice notes that users provide to represent their everyday practices, motivations, and heritage. This profile shapes the agent's tone and suggestions, moving guidance from generic to grounded in each person's context. Developed through three user studies, the project shows how cultural resonance makes dietary support more relevant, respectful, and engaging. Combining interaction design and AI prompt engineering, Sofra challenges universal approaches to health technology and advocates for systems that adapt to, rather than flatten, cultural differences.
