PHARA: an augmented reality grocery store assistant

Staying healthy is one of the most important things in life, and our daily decisions determine how healthy or unhealthy we are. We present PHARA, an augmented reality (AR) mobile assistant that supports decision-making for food products at grocery stores. Using a user-centered design approach we investigated the possibilities of AR technology in presenting food product information. Then, following an iterative design process, we implemented a mobile AR application to support users with typical decision-making tasks that take place at grocery stores. In this paper, detailed explanations of the working prototype of PHARA and its use case are presented.
