Rendezfood – Deployment of social, local and playful approaches for regional advertising concepts in the publishing industry

Rendezfood Logo
Duration: 2019-2022

 

Sponsorship: EFRE-Förderung des Landes Nordrhein-Westfalen in scope of CreateMedia.NRW

Contact person: Dr. Thomas Ludwig – Philip Weber – Kevin Krings

Online media present daily newspapers with the challenge of rethinking their business model in the wake of declining circulation figures. At the same time, new media also offer new opportunities to increase the reach of established publishers. This is particularly important for the central advertising business and requires the transformation from a mono-media information service to a multi-media, digital service provider. Rendezfood is intended to make this transformation possible. Therefore a platform is being developed for an exemplary field of the catering industry (eventually for the retail business too), which enables new concepts for marketing initiatives. The aim is to intensify customer loyalty through so-called “game mechanics”, i.e. the use of playful concepts in non-playful contexts. To this end, location-based services will be developed that allow better, situational adaptation and provision of information. The customer’s interface is based on innovative interaction concepts such as dating-based chatbots. The personification of the advertised products thus receives specific character traits (e.g. a “moody burger”), whereby the customer can be addressed in a much more emotional way. The realization of the platform as a white-label solution allows smaller, regional daily newspapers to enter the digital transformation process of the advertising market.

  • Weber, P., Ludwig, T. & Michel, L. K. (2023)The role of technology use in food practices during the COVID-19 pandemic

    IN International Journal of Gastronomy and Food Science, Pages: 100687 doi:10.1016/j.ijgfs.2023.100687

    Over the last three years, COVID-19, with its lockdowns, social restrictions, and work from home structures, had a significant influence on our daily lives. The resulting changes in technology practices are likely to be explored in the years ahead. We will contribute to this exploration by looking specifically at the impact of COVID-19 on everyday food practices and the role of involved technology. To explore food practices and technology use, we conducted a qualitative interview study with 16 interviewees and delved into the underlying influencing factors behind them. Thereby we can better understand potential behavioral changes and technology usage by people to design not only for future pandemics and exceptional situations but to also for non-pandemic times.

  • 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.

    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

    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.

    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.
