  Krings, K., Weber, P., Jasche, F. & Ludwig, T. (2022)FADER: An Authoring Tool for Creating Augmented Reality-Based Avatars from an End-User Perspective

  Although augmented reality (AR) is becoming more common in our society, there are few specialized end-user tools for appropriate AR content creation. Most tools are focused on creating entire 3D applications or require extensive knowledge in programming and 3D modeling. With reference to End-User Development (EUD), we present a design case study for an end-user-friendly authoring tool that allows domain experts to create individual AR avatars in the field of Human-Food Interaction. After reviewing current approaches and design guidelines, we designed and implemented FADER, a web-based tool for creating AR-based food avatars. Our evaluation shows that playful design fosters immersion, and that abstract placeholders and highly simplified controls empower non-developers to create AR content. Our study contributes to a better understanding of end-user needs and practices during the AR creation process and informs the design of future AR authoring tools.

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

  Designing Interactive Systems Conference 2021. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 638–650 doi:10.1145/3461778.3461998
  [BibTeX] [Abstract] [Download PDF]

  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.
