Vita

Kevin Krings studied at the University of Siegen for a bachelor’s degree in information systems and, after graduating in 2018, continued his studies in a master’s degree in information systems. Besides his studies he worked as a working student in the field of software development and consulting at i-soft GmbH in Siegen and also underwent further training as an instructor at the IHK Siegen. Even before his studies, he completed an apprenticeship as an IT specialist in application development at Viega GmbH & Co.KG in Attendorn and worked at the company for another fifteen months as a software developer.

Since June 2020 Kevin is a research assistant at the Chair of Cyber-Physical Systems. His current focus is on the support and implementation of the research project “Rendezfood”, which aims to implement a novel advertising concept using social, location-based and playful approaches. He was already involved in the project as part of his project and master thesis.

His primary research interests include end-user development for technologies such as augmented reality, conversational agents and machine learning, as well as the appropriation of cyber-physical systems in various domains.

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

    IN Mensch und Computer 2022 – Tagungsband doi:10.1145/3543758.3543778
    [BibTeX] [Abstract] [Download PDF]
    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

    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.
