CSCW '24Session 1g: Contextualizing Fairness in AI

Articulation Work and Tinkering for Fairness in Machine Learning

The field of fair AI aims to counter biased algorithms through computational modelling. However, it faces increasing criticism for perpetuating the use of overly technical and reductionist methods. As a result, novel approaches appear in the field to address more socially-oriented and interdisciplinary (SOI) perspecti…

Shock Me The Way: Directional Electrotactile Feedback under the Smartwatch as a Navigation Aid for Cyclists

Cycling navigation is a complex and stressful task as the cyclist needs to focus simultaneously on the navigation, the road, and other road users. We propose directional electrotactile feedback at the wrist to reduce the auditory and visual load during navigation-aided cycling. We designed a custom electrotactile grid…

WorkFit: Designing Proactive Voice Assistance for the Health and Well-Being of Knowledge Workers

Prior research has designed and evaluated Voice Assistance (VA) for different settings such as the home, school, and public spaces. Office environments have been relatively understudied, leaving a gap in understanding the essential factors for designing a VA specifically for work settings. In this study, we developed…

A Comparative Long-Term Study of Fallback Authentication Schemes

Fallback authentication, the process of re-establishing access to an account when the primary authenticator is unavailable, holds critical significance. Approaches range from secondary channels like email and SMS to personal knowledge questions (PKQs) and social authentication. A key difference to primary authenticati…

Analyzing Security and Privacy Advice During the 2022 Russian Invasion of Ukraine on Twitter

The Russian Invasion of Ukraine in 2022 resulted in a rapidly changing cyber threat environment globally and incentivized the sharing of security and privacy advice on social media. Previous research found a strong impact of online security advice on end-user behavior. Twitter is an important platform for sharin…

Understanding Users' Interaction with Login Notifications

Login notifications intend to inform users about sign-ins and help them protect their accounts from unauthorized access. Notifications are usually sent if a login deviates from previous ones, potentially indicating malicious activity. They contain information like the location, date, time, and device used to sign in.…

Can You Ear Me? — A Comparison of Different Private and Public Notification Channels for the Earlobe

"The earlobe is a well-known location for wearing jewelry, but might also be promising for electronic output, such as presenting notifications. This work elaborates the pros and cons of different notification channels for the earlobe. Notifications on the earlobe can be private (only noticeable by the wearer) as well…

52 Weeks Later: Attitudes Towards COVID-19 Apps for Different Purposes Over Time

The COVID-19 pandemic has prompted countries around the world to introduce smartphone apps to support disease control efforts. Their purposes range from digital contact tracing to quarantine enforcement to vaccination passports, and their effectiveness often depends on widespread adoption. While previous work has iden…

A World Full of Privacy and Security (Mis)conceptions? Findings of a Representative Survey in 12 Countries

Misconceptions about digital security and privacy topics in the general public frequently lead to insecure behavior. However, little is known about the prevalence and extent of such misconceptions in a global context. In this work, we present the results of the first large-scale survey of a global population on miscon…

Home Is Where the Smart Is: Development and Validation of the Cybersecurity Self-Efficacy in Smart Homes (CySESH) Scale

The ubiquity of devices connected to the internet raises concerns about the security and privacy of smart homes. The effectiveness of interventions to support secure user behaviors is limited by a lack of validated instruments to measure relevant psychological constructs, such as self-efficacy - the belief that one is…
