We present KiriPhys, a new type of data physicalization based on kirigami, a traditional Japanese art form that usespaper-cutting. Within the kirigami possibilities, we investigate how different aspects of cutting patterns offer opportunities for mappingdata to both independent and dependent physical variables. As a first step towards understanding the data physicalization opportunitiesin KiriPhys, we conducted a qualitative study in which 12 participants interacted with four KiriPhys examples. Our observations of howpeople interact with, understand, and respond to KiriPhys suggest that KiriPhys: 1) provides new opportunities for interactive, layereddata exploration, 2) introduces elastic expansion as a new sensation that can reveal data, and 3) offers data mapping possibilities whileproviding a pleasurable experience that stimulates curiosity and engagement.

Social media is becoming an inseparable component of our daily lives --- with the promise of providing an avenue for building connections with others worldwide. However, persuasive media coverage suggests that in reality, online social media is falling short of promises to provide a space for meaningful connections and interactions. Given that the landscape of social media is ever-changing, it is important to periodically probe into people's social media experiences to identify the challenges and nuances of how people make connections with others and experience the content that social media provides. To explore people's social media experiences, in this work, we conducted a qualitative exploratory study in which we took a two-pronged approach: (1) we created two small technology probes to elicit people’s thoughts and comments on how alternative features and functionalities could change how they use social media, and (2) conducted one-on-one creativity sessions to encourage our 16 study participants to explore how social media impact their lives and how it might transform in the future. The participants openly and enthusiastically discussed their experiences, connections, and agency on social media. Our findings suggest that the participants want features to increase expressivity, the ability to control content curation, and opportunities to make connections beyond what current social media platforms provide. We discuss the impact of privacy and anonymity in shaping social media experiences as well as the tension among agency, relevance, content curation, and echo chambers.

Mobile Data VisualizationI N many ways, mobile visualization is proliferating. Yet, most visualizations on mobile devices are still drawing from the experiences we have with visualizations on larger screens. In this chapter, we present an ideation methodology that can help us to imagine future mobile visualizations through a human-centered design approach. We begin by outlining the general approach of the methodology and then describe how it was adapted and changed to fit the needs of three groups. This chapter is an experience report about how three different groups adapted a design methodology to suit their circumstances. All the design method adaptions explored were successful in encouraging a wide range of ideas to emerge.
