ORA is an innovative food optimization concept designed to tackle food waste in public dining spaces. Leveraging emerging technologies such as LiDAR and AI inference on the cloud, ORA integrates diet tracking and meal recommendation systems for both consumers and restaurants. The system consists of three interconnected components: a customer-facing mobile application, restaurant monitoring software, and a ceiling-mounted LiDAR camera. Together, these elements provide a seamless, data-driven approach to optimizing meal portioning, improving user dining experiences, and promoting sustainable food consumption. By analyzing meal selections and consumption patterns, ORA enables informed decision-making that benefits both consumers and restaurant operators.
