Networked public displays offer new ways of connecting communities through user-generated content. For example, they allow taking situated snapshots, i.e., photos taken through a display-attached camera, and viewing them on displays in the network or potentially somewhere on the web. Little research has looked into users' privacy concerns for this novel type of content. This paper reflects on two longitudinal studies of the Moment Machine application that was running in the UK and Switzerland…

"Fun place within a serious space": stimulating community interaction and engagement through situated snapshots in a university setting
A 15-week "in the wild" deployment of the Moment Machine 2.0 that allowed taking situated snapshots at a university and it is shown how the application affected community interaction and sense of community as defined by McMillan and Chavis.
User Expectations for Media Sharing Practices in Open Display Networks
The results suggest a clear preference for scenarios where content is both local and directly related to the person that is publishing it, and confirms the opportunity that open displays networks may represent a new media for self-expression.
Foundations for Designing Public Interactive Displays that Provide Value to Users
This work proposes that additional understanding is required around how and when public interactive displays are able to offer value to users, and tackles 9 aspects of value across 4 factors: people, location, community, and time.
GTmoPass: two-factor authentication on public displays using gaze-touch passwords and personal mobile devices
GTmoPass is proposed, an authentication architecture that enables Multi-factor user authentication on public displays that employs a shoulder-surfing resilient multimodal scheme that combines gaze and touch input for password entry.
A Risk Management Framework for User-Generated Content on Public Display Systems
This study proposes a framework that supports the systematic elicitation of the risks involved, their prioritisation, and the selection of the specific combination of moderation techniques that is able to reduce risk to a level that is deemed acceptable, while minimising the moderation effort and the impact on the willingness of users to publish their content.
Why public displays invite use in some places but not in others : a comparative study of UBIOulu
The purpose of this study is to investigate the mystery as to why public displays invite use in some places but not in others. This is a comparative study of UBIOulu, where Open UBI Oulu project
Pandemic Displays: Considering Hygiene on Public Touchscreens in the Post-Pandemic Era
It is found that there is demand for improved awareness of public displays’ hygiene status, especially among those with stronger concerns about COVID-19, and considerations for designing for hygiene on public displays are presented.


Social networked displays: integrating networked public displays with social media
A possible solution for integrating networked public displays could be in allowing users to use it as both input and output device for images, i.e., allowing them to a) post situated snapshots onto Facebook through an on-display camera and b) show images on the screens taken through Instagram.
The effects of filtered video on awareness and privacy
The results suggest that the blur filter, and to a lesser extent the pixelize filter, have a level suitable for providing awareness information while safeguarding privacy.
Designing Shared Public Display Networks - Implications from Today's Paper-Based Notice Areas
This work investigated today's practices surrounding shared notice areas, i.e. places where customers and visitors can put up event posters and classifieds, such as shop windows or notice boards, and provides a systematic assessment of factors that inhibit or promote the shared use of public display space.
Personalisation and privacy in future pervasive display networks
This work describes a series of usage models and design goals for display personalisation and presents Tacita, a system that supports these models and goals and provides comprehensive personalisation features while preventing the creation of user profiles within the display infrastructure, thus helping to preserve users' privacy.
Beyond Web 2.0: Challenges in Personalizing for Networked Public Display Environments
This article enumerates the key research challenges that stem from bringing personalization to public displays, namely in the areas of user identification; profile location; profile content; content tailoring; model refinement; and applications that require personalisation.
The interacting places framework: conceptualizing public display applications that promote community interaction and place awareness
The Interacting Places Framework is described, a conceptual framework for designing applications in this novel research space that was developed based on four distinct public display studies and focuses on 4 elements: content providers, content viewers, communication channels, and an awareness diffusion layer that describes how community awareness building happens.
Digifieds: insights into deploying digital public notice areas in the wild
The design and development of Digifieds (derived from digital classified), a digital public notice area, is reported on, which was deployed and evaluated in an urban environment in the context of the UbiChallenge 2011 in Oulu, Finland over the course of 6 months.
Capture the Moment: "In the Wild" Longitudinal Case Study of Situated Snapshots Captured Through an Urban Screen in a Community Setting
A first longitudinal case study of 12 weeks of such an application -- Moment Machine -- deployed "in the wild" on an urban screen facing the street, showing engagement stimulated by situated snapshots within a place-based community where the screen is located.
Is Anyone Looking? Mitigating Shoulder Surfing on Public Displays through Awareness and Protection
This work provides participants with awareness of shoulder-surfing moments, which in turn helps both parties regulate their behaviours and mediate further social interactions, and provides methods that protect information when shoulder-Surfing is detected.
Pins and posters: Paradigms for content publication on situated displays
Researchers implemented two complementary paradigms for public displays in the Instant Places system, which were deployed on 10 displays in diverse urban locations for six months and improve the understanding of what might drive user-generated content in networks of urban displays.
