Trauma-Informed Computing: Towards Safer Technology Experiences for All

CHI Conference on Human Factors in Computing Systems · 2022 · 142 citations

Trauma is the physical, emotional, or psychological harm caused by deeply distressing experiences. Research with communities that may experience high rates of trauma has shown that digital technologies can create or exacerbate traumatic experiences. Via three vignettes, we discuss how considering the possible effects of trauma and traumatic stress reactions provides an explanatory lens with new insights into people’s technology experiences. Then, we present a framework—trauma-informed computing—…

"It's a scavenger hunt": Usability of Websites' Opt-Out and Data Deletion Choices

We conducted an in-lab user study with 24 participants to explore the usefulness and usability of privacy choices offered by websites. Participants were asked to find and use choices related to email marketing, targeted advertising, or data deletion on a set of nine websites that differed in terms of where and how these choices were presented.

Encouraging Users to Change Breached Passwords Using the Protection Motivation Theory

ACM Transactions on Computer-Human Interaction · 2024-08-30 · 13 citations

We draw on the Protection Motivation Theory (PMT) to design interventions that encourage users to change breached passwords. Our online experiment ( \(n=1{,}386\) ) compared the effectiveness of a threat appeal (highlighting the negative consequences after passwords were breached) and a coping appeal (providing instructions on changing the breached password) in a 2 \(\times\) 2 factorial design. Compared to the control condition, participants receiving the threat appeal were more likely to inten…

Smart home technologies are making their way into families. Parents' and children's shared use of smart home technologies has received growing attention in CSCW and related research communities. Families and children are also frequently featured as target audiences in smart home product marketing. However, there is limited knowledge of how exactly children and family interactions are portrayed in smart home product marketing, and to what extent those portrayals align with the actual consideratio…

Better Together: The Interplay Between a Phishing Awareness Video and a Link-centric Phishing Support Tool

2024-05-11 · 6 citations

Two popular approaches for helping consumers avoid phishing threats are phishing awareness videos and tools supporting users in identifying phishing emails. Awareness videos and tools have each been shown on their own to increase people’s phishing detection rate. Videos have been shown to be a particularly effective awareness measure; link-centric warnings have been shown to provide effective tool support. However, it is unclear how these two approaches compare to each other. We conducted a betw…
