  abstract  = {Given the ubiquity of smartphones in everyday life and their role as gateways to personal and professional activities, timely software updates are critical for digital security. Although updates address known vulnerabilities, many users delay or ignore them. This happens not necessarily from a lack of awareness, but because updates interrupt device use. This paper investigates the use of interactive public displays in semi-public spaces to encourage security-enhancing behavior. We present and empirically evaluate SmartUpdate, a public-display application that guides users through performing manual updates and enabling automatic updates on their smartphone devices. A field study provides insights into how people notice, approach, and engage with educational content on public displays. Findings show that participants often updated their smartphones in parallel while interacting with the display, yet attracting engagement remained challenging, mainly due to time constraints. Overall, the results indicate that public displays can promote secure behavior effectively when location, timing, and audience are carefully aligned with application design.},
