  Weber, P., Krings, K., Nießner, J., Brodesser, S. & Ludwig, T. (2021)FoodChattAR: Exploring the Design Space of Edible Virtual Agents for Human-Food Interaction

  There has been recent criticism from researchers towards simple replication of traditional role models in the design of virtual agents and robots, and a call for new forms of interaction and communication with technology. By exploring the field of Human-Food interaction (HFI) – a sub-area of Human-Computer Interaction (HCI) which aims to investigate the diversity of ways people interact with food – we therefore specifically examine the design space of edible anthropomorphic virtual agents (EAVAs). To understand human-to-food interactive communication, we conducted an interview study with 19 participants, followed by a co-design workshop on the design of conversational agents for personified food. Based on the results, we implemented a prototype called FoodChattAR that employs augmented reality and chatbots to interact and communicate with food. Our evaluation with 21 participants shows that FoodChattAR turns eating into fun, while at the same time the food conveys relevant societal facts about itself. We contribute to the field of HCI by introducing EAVAs as a novel human-to-food interaction.

  Weber, P., Engelbutzeder, P. & Ludwig, T. (2020)“Always on the Table”: Revealing Smartphone Usages in everyday Eating Out Situations

  Research on food practices and technology use is becoming more common, albeit with a constant technological determinism with respect to the support of individual practices. Nevertheless, there are only a few empirical studies that outline the use of current technologies within eating contexts. We therefore conducted an empirical study on the practice of eating out and the use of mobile technologies before, during, and after eating. Our investigation consists of a qualitative interview study (n=29) complemented by a large observational study (n=458) within several restaurant settings. Our results indicate a strong reluctance to use technology while eating and highlights several design spaces focusing on before and after the actual eating. Within our paper, we uncover a strong relationship between smartphone use and the social settings in which the interaction takes place. We contribute to the emerging research field of Human-Food Interaction by outlining design spaces for supporting practices around food consumption when eating out.
