AR-Based Food Traceability as a Means for Sustainable Development

Abstract

This paper focuses on traceability as a means to ensure sustainability during food development by using augmented reality and addressing the needs of farmers/producers, development and retail companies, and consumers. After reviewing related work, the needs are outlined for an application with a highly visual interface that lets all involved parties insert, explore, and view data about food products, starting from their origin and dietary/heritage value until their placement in a market. In this direction, the research questions examined the usability of such an application along with its validity concerning whether customers would choose healthy food products based on certain criteria, ensuring sustainability at all levels. Data are selected from predefined lists where possible and propagated without disruption from farmers to markets to avoid errors. The analysis led to the AR application, FoodTrace, whose design and prototype implementation are also presented. The evaluation was encouraging as the research goals were largely met regarding both usability and content value and will help further develop the application.
