In late 2017, Uber was nearly a year into a complete redesign of its driver-facing mobile app. This case study describes the research program we executed to support the app's global beta launch, which aimed to "Build Together" with drivers across different geographies. With the goal of minimizing the time-space-cognitive distance between beta drivers and the product team, we deployed researchers in 7 cities for a 3-week research sprint, combining four high-touch ethnographic methods to understand drivers' reaction to the product. Unusually, we used an internal Google+ social media site to post a continual stream of raw, unsynthesized "atomic evidence" from research activities. The G+ unexpectedly went viral, creating extremely high engagement, impact, and stakeholder sentiment. Here we discuss the pros, cons, and impact of our approach, and also how success came from creating space for others to create, engage with, and act on raw evidence from the field.

Current food consumption patterns are unsustainable. The food system is globalized and dominated by a few large organisations, which dis-empowers people to make changes to it. However, grassroots communities are important in engendering positive change from the bottom up. Long-term thinking is a key to empowering these communities in transitioning towards sustainable food systems. This research is concerned with practices of "futuring" in grassroots communities and how HCI can facilitate openness, participation, and coordination in constructing visions of the future, and in reconciling these with the everyday practices of the communities.

Conversational agents (CAs) become more popular and useful at home. Creating the persona is an important part of designing the conversational user interface (CUI). Since the CUI is a voice-mediated interface, users naturally form an image of the CA's persona through the voice. Because that image affects users' interaction with CAs while using a CUI, we tried to understand users' perception via drawing method. We asked 31 users to draw an image of the CA that communicates with the user. Through a qualitative analysis of the collected drawings and interviews, we could see the various types of CA personas perceived by users and found design factors that influenced users' perception. Our findings help us understand persona perception, and that will provide designers with design implications for creating an appropriate persona.

Reflection-in-action (RiA) refers to teachers' reflections on their teaching performance during busy classroom routines. RiA is a demanding competence for teachers, but little has been known about how HCI systems could support teachers' RiA during their busy and intensive teaching. To bridge this gap, we design and evaluate an ambient information system named ClassBeacons. ClassBeacons aims to help teachers intuitively reflect-in-action on how to divide time and attention over pupils throughout a lesson. ClassBeacons subtly depicts teachers' division of time and attention over pupils through multiple light-objects distributed over students' desks. Each light-object indicates how long the teacher has been cumulatively around it (helping an adjacent student) by shifting color. A field evaluation with eleven teachers proved that ClassBeacons enhanced teachers' RiA by supporting their sensemaking of ongoing performance and modification of upcoming actions. Furthermore, ClassBeacons was experienced to unobtrusively fit into teachers' routines without overburdening teaching in progress.

Prior work has demonstrated that energy education programs designed for young children can influence the adoption of energy efficiency measures in the home. Here, we introduce the Know Your Energy Numbers (KYEN) program, an energy education program designed to teach an older audience of pre-teens, or tweens, about: (i) their energy consumption lifestyles, (ii) available residential energy tools, and (iii) methods to extract insights from their energy data. We also describe results from two pilots with 18 tweens from Girl Scout and Boy Scout troops living in Northern California. We report on how participants and their families reacted to our energy-based curricula, the benefits and challenges they perceived about using energy tools, and their preferences regarding the display of home energy data. We conclude with a brief discussion of the outcomes and limitations of this work before describing next steps for the program.

Mobile behaviour change applications should be evaluated for their effectiveness in promoting the intended behavior changes. In this paper we argue that the 'gold standard' form of effectiveness evaluation, the randomised controlled trial, has shortcomings when applied to mobile applications. We propose that N-of-1 (also known as single case design) based approaches have advantages. There is currently a lack of guidance for researchers and developers on how to take this approach. We present a framework encompassing three phases and two related checklists for performing N-of-1 evaluations. We also present our analysis of using this framework in the development and deployment of an app that encourages people to walk more. Our key findings are that there are challenges in designing engaging apps that automate N-of-1 procedures, and that there are challenges in collecting sufficient data of good quality. Further research should address these challenges.

In this paper, I speculate on a future where our need to socialize physically is solely to exchange bacteria. With our biological data being in the hands of private companies and governments and our environments' microbiomes becoming less diverse, our social systems, social identities and social interactions are redefined and reinvented to adapt to this new reality. In this world, everyone wears a "social microbial prosthesis" that analyzes their microbial composition from their breath and reveals sensitive information on their chest. The microbial prosthesis would be able to give off information not only on the microbial composition but also on the mental and physical health of a person. This second skin plays a role in controlling communication and interaction between people, where one is able to, by inspecting surrounding people's prosthesis, take careful considerations of who to interact with and who to avoid. Social Microbial Prosthesis is a critique of the race of private companies and governments to collect our biological data, the role of commercializing such data in shaping and changing our social identities and a response to the loss of microbial diversity in our environments due to our modern lifestyles and surroundings.

We introduce a novel video chat interface with a 360° photo as background in order to offer richer contextual and background information. We conduct a preliminary user evaluation in a lab setting. Paired participants were randomly assigned to two conditions, using regular interface or 360° photo interface. Each pair video chatted in pairs, then completed a post-study survey and answered several questions about their experience. Participants reported to have less behavioral interdependence and more inclusion using 360° photo video chat interface. They also reported having strong interest in employing it in long-distance intimate relationship, and made some suggestions for design iterations.

This paper introduces the concept of wellbeing-as-interaction. Instead of designing and evaluating technologies that locate wellbeing in the individual, this paper presents early-stage work on designing technologies for people to collaboratively express, interpret, discuss and enact wellbeing. To explore this concept, we examined the wellbeing of six pairs of university students through a 7-day deployment of a technology probe 'MoodCloud'. MoodCloud consisted of a mobile app and an ambient display to share wellbeing updates through colour. We observed three patterns of wellbeing interactions: updates, follow-ups, and message chains. Wellbeing interactions benefitted from the ambiguity of colour and a clearly defined target audience, but students also communicated through other channels to make sense of updates and to enact support. The concept of wellbeing-as-interaction seeks to offer an analytic lens for the CHI community as well as inspiration for novel wellbeing technologies that emphasise meaningful interactions with friends.

We demonstrate the online deployment of Geollery, a mixed reality social media platform. We introduce an interactive pipeline to reconstruct a mirrored world at two levels of detail - the street level and the bird's-eye view. Instead of using offline 3D reconstruction approaches, our system streams and renders a mirrored world in real time, while depicting geotagged social media as billboards, balloons, framed photos, and virtual gifts. Geollery allows multiple users to see, chat, and collaboratively sketch with spatial context in this mirrored world. We demonstrate a wide range of use cases including crowdsourced tourism, interactive audio guide with immersive spatial context, and meeting remote friends in mixed reality. We envision Geollery will be inspiring and useful as a standalone social media platform for those looking to explore new areas or looking to share their experiences. Please refer to https://geollery.com for the paper and live demos.
