Card-based design tools–design cards–increasingly present opportunities to support practitioners. However, the breadth and depth of the design card landscape remain underexplored. In this work, we surveyed 103 design practitioners to assess current usages and associated barriers. Additionally, we analyzed and classified 161 decks of design cards from 1952-2020. We held a workshop with four experienced practitioners to generate initial categories, and then coded the remaining decks. We found that the cards contain seven different types of design knowledge: Creative Inspiration; Human Insights; Material & Domain; Methods & Tooling; Problem Definition; Team Building; and Values in Practice. The content of these cards can support designers across design stages; however, most are intended to support the early stages of design (e.g., research and ideation) rather than later design stages (e.g., prototyping and implementation). We share additional patterns uncovered and provide recommendations to support the future development and adoption of these tools.

Economically disadvantaged migrant workers are one of the most vulnerable groups in healthcare. Studies have shown that chatbots can help patients and health professionals in healthcare settings. However, the design of health chatbots for migrant workers has not been thoroughly investigated. Scenario-based interviews with nineteen participants, including ten economically disadvantaged Thai migrant workers and nine relevant stakeholders, were conducted to examine how they seek healthcare, obtain health information, and communicate with health professionals to gain a deeper understanding of the barriers that migrant workers encounter in healthcare. The findings of the interview show that migrant workers face a variety of barriers, such as a lack of familiarity with the healthcare system in the host country, language barriers, cultural barriers to seeking healthcare, and communication barriers with health professionals. Then, the technological design strategies and the benefits of health chatbots from the perspective of migrant workers were discussed, including their potential to help migrant workers navigate the healthcare system step-by-step, obtain reliable health information, improve their health literacy, and facilitate communication with health professionals. Finally, five design implications for chatbots were proposed to guide future development of health chatbots to help migrant workers. Policymakers and health professionals can benefit from the design implications of migrant worker-centered health chatbots when they develop health chatbots that promote the health and well-being of migrant workers.

Sexual health is an important domain that deserves more HCI attention, such as supporting the practices of men who have sex with men (MSM) against HIV risks. One current clinical approach to addressing this issue is to use preventive medicine like pre-exposure prophylaxis (PrEP). As medication adherence of PrEP is challenging that involves users' individual knowledge, sex practices, relational status, and community support, technological mediation benefits from a human-centered perspective that goes beyond individual-level support to understand MSM's needs so as to design a holistic technological intervention for them. With an in-depth interview (n = 22) with MSM from two major cities in Taiwan, we drew on the theoretical framework of the social ecological model and identified three levels of influences, including individual, interpersonal, and sociocultural, that shape the enablers, inhibitors, risks and challenges, and support towards MSM's PrEP use. We proposed correspondent technological design implications to support what we found based on the understanding of our participants.

In this workshop, we intend to bring scholars and practitioners of MobileHCI conference who are interested in designing technology use for children and their parents. Parents are concerned with technology addiction for their children but generally feel loss of control in the ubiquity of mobile devices. We believe mobile design community can contribute meaningful ideas in this space. The goal of this workshop is for participants to co-develop a shared vocabulary and framework for "designing bounded and nuanced technology" as a strategy to be deployed in conceiving and implementing mobile technologies for family use.

An important question for HCI is to understand how and why visual search strategy is adapted to the demands imposed by the task of searching the results of a search engine. There is emerging evidence that a key part of the answer concerns the expected information gain of each of the set of available information gathering actions. We build on previous research to show that people are acutely sensitive to differences in the spacing and in the number of items returned by the search engine. These factors cause shifts in the efficiency of the available information gathering actions. We focus on an image browsing task, and show that, as a consequence of changes to the efficiency of available actions, people make small but significant changes to eye-movement strategy.
