Vita

Philip Weber studied Business Information Systems (B.Sc.) at the University of Applied Sciences Bonn-Rhein-Sieg. After his degree in 2016, he went on to the University of Siegen to study Human Computer Interaction (M.Sc.) and graduated in 2019.

Since April 2019 he is a research associate and PhD student in the department of Cyber-Physical Systems. Initially, he was part of the ERDF/EU-funded research project Rendezfood, which developed social, location-based and game-based approaches for the restaurant industry. His current role focuses on the execution of the RegioQuest research project with the goal of improving the visibility of apprenticeships and job opportunities through the use of game-based and location-based approaches.

His research interests are in the area of Human-Food Interaction, Conversational Agents and Gamification.

  • 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., Grönewald, L. & Ludwig, T. (2022)Reflection on the Octalysis framework as a design and evaluation tool

    6th International GamiFIN Conference 2022 (GamiFIN 2022). Tampere, Finland, Pages: 75–84
    [BibTeX] [Abstract]
    The Octalysis framework is a gamification framework used for the design and evaluation of “human-focused” systems. Although several practitioners have applied it within their daily work, only a few academic articles have reflected on its applicability. With this study, we present how and where the framework is currently applied based on a large-scale literature study and reflect on the potentials and obstacles of using it within a Human Computer Interaction (HCI) master’s class. Our empirical findings show that the use of the Octalysis framework is often simplified and can also be overwhelming. The results further reveal that the framework itself can be helpful in the creation and evaluation of concepts, especially when extensive user research is not possible (e.g., due to time constraints). We contribute to the field of gamification by critically reflecting on the use of the Octalysis framework.

  • 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.

    Proceedings of the 11th Nordic Conference on Human-Computer Interaction: Shaping Experiences, Shaping Society. New York, NY, USA, Publisher: Association for Computing Machinery, Pages: 1–13 doi:10.1145/3419249.3420150

    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.
