[more ▼] Conversational agents (CAs) that deliver proactive interventions can benefit users by reducing their cognitive workload and improving performance. However, little is known regarding how such interventions would impact perception of CA’s appropriateness in voice-only, decision-making tasks. We conducted a within-subjects experiment (N=30) to evaluate the effect of CA’s feedback delivery strategy at three levels (no feedback, unsolicited, and solicited feedback) in an interactive food ordering scenario. We discovered that unsolicited feedback was perceived to be more appropriate than solicited feedback. Our results provide preliminary insights regarding the impact of proactive feedback on CA perception in decision-making tasks.

[more ▼] Health misinformation in social networks requires immediate attention due to its severe consequences, as exemplified by the COVID-19 pandemic response on social media. However, the existing solutions designed to combat misinformation generally overlook the unique characteristics of health misinformation domain. Through a review of relevant literature and a critical analysis of current anti-misinformation solutions, we have identified significant user-side issues that undermine the effectiveness of existing approaches in addressing health misinformation. To tackle these issues, we put forth several strategies to empower users in combating health misinformation. Our research contributes to understanding the challenges associated with health misinformation correction on social networks.

[more ▼] Persuasive tactics intend to encourage users to open advertising emails. However, these tactics can overwhelm users, which makes them frustrated and leads to lower open rates. This paper intends to understand which persuasive tactics are used and how they are perceived by users. We first developed a categorization of inbox-level persuasive tactics in permission-based advertising emails. We then asked participants to interact with an email inbox prototype, combined with interviews (N=32), to investigate their opinions towards advertising emails and underlying persuasive tactics. Our qualitative findings reveal poor user experience with advertising emails, which was related to feeling surveilled by companies, forced subscriptions, high prior knowledge about persuasive tactics, and a desire for more agency. We also found that using certain persuasive tactics on the inbox level is perceived as ethically inappropriate. Based on these insights, we provide design recommendations to improve advertising communication and make such emails more valuable to users.

[more ▼] Educators increasingly agree on the importance of teaching Human-Computer Interaction (HCI) to Computer Science (CS) students, but there is debate on how to best integrate HCI into CS curricula. Unfortunately, standard course evaluations typically do not provide sufficient insights for improving HCI classes. In the present article, we used a human-centered design approach to evaluate our HCI classes, building on a qualitative study with CS students from four introductory HCI classes over two years. We report on a qualitative assessment through interviews, photo elicitation and sentence completion. Specifically, we addressed four research questions: which contents were the most relevant, how students experienced the courses, how they view the role of HCI in CS, and which outcomes they perceived from the HCI courses. We gathered rich qualitative insights beyond the standard course evaluations and derived concrete enhancements for future course iterations. We discuss implications for other HCI educators and contribute recommendations for the living HCI curriculum. Furthermore, we reflect on the usefulness of our methodological approach to collect in-depth constructive feedback from students.
