Activity in Human-Food Interaction (HFI) research is skyrocketing across a broad range of disciplinary interests and concerns. The dynamic and heterogeneous nature of this emerging field presents a challenge to scholars wishing to critically engage with prior work, identify gaps and ensure impact. It also challenges the formation of community. We present a Systematic Mapping Study of HFI research and an online data visualisation tool developed to respond to these issues. The tool allows researchers to engage in new ways with the HFI literature, propose modifications and additions to the review, and thereby actively engage in community-making. Our contribution is threefold: (1) we characterize the state of HFI, reporting trends, challenges and opportunities; (2) we provide a taxonomy and tool for diffractive reading of the literature; and (3) we offer our approach for adaptation by research fields facing similar challenges, positing value of the tool and approach beyond HFI.

Designing wearable technology that supports physical and social engagement in a collocated setting is challenging. In this research, we reached out to an expert community of crafters of social experiences: larpers (live action role players). Larpers and larp designers have a longstanding tradition of designing and making use of a variety of elements, such as costumes, physical objects, environments, and recently also digital artifacts. These are crafted in support of co-experience values that we argue can inform the design of social wearables. We engaged in a co-design process with a game designer and co-founder of a larp production company, and embedded the resulting social wearables in a larp. Here, we present the results of this design and implementation process, and articulate design affordances that resonate with our larp designer' values. This work may inspire and inform researchers and designers creating wearable technology that is aimed at supporting collocated engagement.
