In the design of contemporary mapping technologies, effective navigation has become synonymous with the quickest route, limiting the extent to which people engage with the places they move in and around. This paper unsettles the prevalent focus on efficiency and explores opportunities to support placemaking during everyday practices of navigation. Drawing on 16 interviews and using the Value Sensitive Design framework, we identify seven alternative values, beyond efficiency, that hold significance for people navigating the city. Through a series of two design workshops, we further examine how and when these values come to matter during navigation. Our findings suggest four ways in which the prevalent design standards of navigational apps work against these values, and highlight their potential contribution to placemaking during technology mediated navigation. In doing so, this paper contributes to placemaking research and ongoing questions of efficiency and optimization within HCI.

We examine input visualizations, visual representations that are designed to collect (and represent) new data rather than encode preexisting datasets. Information visualization is commonly used to reveal insights and stories within existing data. As a result, most contemporary visualization approaches assume existing datasets as the starting point for design, through which that data is mapped to visual encodings. Meanwhile, the implications of visualizations as inputs and as data sources have received little attention—despite the existence of visual and physical examples stretching back centuries. In this paper, we present a design space of 50 input visualizations analyzing their visual representation, data, artifact, context, and input. Based on this, we identify input modalities, purposes of input visualizations, and a set of design considerations. Finally, we discuss the relationship between input visualization and traditional visualization design and suggest opportunities for future research to better understand these visual representations and their potential.

Emergency response to large-scale disasters is often supported with multimedia from social media. However, while these features are common in everyday video calls, the complex needs of 911 and other systems make it difficult to directly incorporate these features. We assess an ME911 (Multimedia-Enabled 911) app to understand how the design will need to deviate from common norms and how callers will respond to those non-standard choices. We expand the role of 911 call taker control over emergency situations to the calling interface while incorporating key features like map-based location finding. Participants’ experiences in mock emergencies show the non-standard design helps callers in the unfamiliar setting of emergency calling yet it also causes confusion and delays. We find the need for emergency-specific deviations from design norms is supported by participant feedback. We discuss how broader system changes will support callers to use these non-standard designs during emergencies.

Although farmers in Sub-Saharan Africa are accessing feature phones and smartphones at historically high rates, they face challenges finding a robust network of agricultural contacts. With local collaborators, we conduct a quantitative survey of 1014 agricultural households in Kagera, Tanzania to characterize technology access, use, and comfort levels in the region. Recognizing the paucity of research on dual-platform technologies that cater to both feature phone and smartphone users, we develop and deploy eKichabi v2, a searchable directory of 9833 agriculture-related enterprises accessible via a USSD application and an Android application. To bridge the gap in affordances between the two applications, we conduct a mixed methods pilot leveraging mobile money agents as intermediators for our USSD application's users. Through our investigations, we identify the advantages, obstacles, and critical considerations in the design, implementation, and scalability of agricultural information systems tailored to both feature phone \textit{and} smartphone users in Sub-Saharan Africa.

User surveys are essential to user-centered research in many fields, including human-computer interaction (HCI). Survey personalization—specifically, adapting questionnaires to the respondents' profiles and experiences—can improve reliability and quality of responses. However, popular survey platforms lack usable mechanisms for seamlessly importing participants’ data from other systems. This paper explores the design of a data-driven survey system to fill this gap. First, we conducted formative research, including a literature review and a survey of researchers (𝑁 = 52), to understand researchers’ practices, experiences, needs, and interests in a data-driven survey system. Then, we designed and implemented a minimum viable product called Data-Driven Surveys (DDS), which enables including respondents’ data from online service accounts (Fitbit, Instagram, and GitHub) in survey questions, answers, and flow/logic on existing survey platforms (Qualtrics and SurveyMonkey). Our system is open source and can be extended to work with more online service accounts and survey platforms. It can enhance the survey research experience for both researchers and respondents.

Music is intrinsically connected to human experience, yet the plethora of choices often renders the search for the ideal piece perplexing, especially when the search terms are ambiguous. This study questions the viability of employing visual data, specifically images, in innovative queries for music search, and it aims to better align search results with users' moods and situational context. We designed and evaluated three prototype systems for music search—TTTune (text-based), VisTune (image-based), and VTTune (hybrid)—to comparatively assess user experience and system usability. In a comprehensive user study involving 236 participants, each participant interacted with one of the systems and subsequently completed post-experimental surveys. A subset of participants also participated in in-depth interviews to further elucidate the potential and the advantages of image-based music retrieval (IMR) systems. Our findings reveal a marked preference for the user experience and usability offered by the IMR approach, as compared with the traditional text-based method. This underscores the potential of the image in an effective search query. Based on these findings, we discuss interface design guidelines tailored for IMR systems and factors affecting system performance, contributing to the evolving landscape of music search methods.

Communicating risk to the public in the lead-up to and during severe weather events has the potential to reduce the impacts of these events on lives and property. Globally, these events are anticipated to increase due to climate change, rendering effective risk communication an integral component of climate adaptation policies. Research in risk communications literature has developed substantial knowledge and best practices for the design of risk messaging. This study considers the potential for quantifying the compliance of severe weather risk messages with these best practices, individually and at scale, and developing tools to improve risk communication messaging. The current work makes two contributions. First, we develop a string-matching approach to evaluate whether messaging complies with best practices and suggest areas for improvement. Second, we conduct an interview study with risk communication professionals to inform the design space of authoring tools and other technologies to support severe weather risk communicators.

Creating technology products using codesign techniques often results in higher end-user engagement compared to expert-driven designs. Codesign sessions are typically structured in flexible and informal ways to achieve equal design partnerships especially in adult-child interactions. This generally leads to better design output, however, it may also increase the enactment of socially constructed stereotypes and biases in ways that negatively affect the experiences of racial minorities and girls/women in design spaces. We codesigned a video game with a K-5 afterschool program located in a working-class, rural, predominantly white county over 20 weeks. We uncover ways that the codesign process and different activity types can create a permissive environment for enacting behaviors that are harmful to minorities. We discuss ways to manage and restructure codesign programs to be more conducive for children and adults from diverse backgrounds, ultimately leading to healthier design partnerships.
