The COVID-19 pandemic disrupted processes interaction designers took for granted, challenging some of our most commonplace design practices. Participatory and situated approaches have been impacted the most: where we engaged stakeholders in-person and in-...

Any active entity that shares space with people is interpreted as a social actor. Based on this notion, we explore how robots that integrate functional utility with a social role and character can integrate meaningfully into daily practice. Informed by ...

Location-based games are highly dependent on the physical environment. One important but often overlooked factor is weather. In this paper we focus on winter weather, as this is a common weather that is often not designed for specifically. By performing ...

What emotional effects does gamification have on users who work or learn with repetitive tasks? In this work, we use biosignals to analyze these affective effects of gamification. After a brief discussion of related work, we describe the implementation ...

Playful interactive game systems are seen as a new and exciting way to enhance social interactions. Although positive results have been reported from previous interventions, many of these games have focused on limited contexts involving players who are ...

"Yes/No-Object" is an interactive object made of metal, electronics, loudspeakers and code. Using ultrasonic sensors, it continuously measures its distance from surrounding objects. It routinely generates and utters words. If anything is close to the ...

Gamification is an increasingly popular strategy for increasing user engagement. But how to design gamified systems? While there is an abundance of industry methods, they often remain elusive in essential steps and lack grounding in evidence. This course ...

Domestic food waste is a world-wide problem that is complex and difficult to tackle as it touches diverse habits and social behaviors. This paper introduces the Grumpy Bin, a smart food waste bin designed for the context of student housing. The Grumpy ...

In this work in progress paper we present our work in the co-design of a playful interactive artifact that encourages people to engage in casual physical activity in the park. The initial testing of our proof-of-concept prototype received extremely ...

When you play, you are deeply involved which is why interaction designers and game designers are increasingly creating playful experiences. However, a pitfall in these digital designs is to focus too much on the game rules and goals. In doing so, we ...

In this paper, we describe the design and outcomes of LocaLudo, a playful and card-based workshop that aims to involve families in the design of interactive architecture. Family members, both children and adults, were invited to build upon local ...

This paper presents the design and study of UNI²BIN, a playful interactive system challenging its users to recycle their textiles so to adopt more sustainable fashion habits. The system initially rewards the user with direct playful interactions when ...

In recent years, gamification - the use of game design elements in non-game contexts - has seen rapid adoption in the software industry, as well as a growing body of research on its uses and effects. However, little is known about the effective design ...

Recent years have seen a rapid proliferation of mass-market consumer software that takes inspiration from video games. Usually summarized as "gamification", this trend connects to a sizeable body of existing concepts and research in human-computer ...
