What is PD-Net?"The PD-NET project aims to lay the scientific foundations for a new form of communications medium with the same potential impact on society as radio, television and the Internet. The goal is to explore the scientific challenges and to assess the new technologies required to enable the emergence of large scale networks of pervasive public displays and associated sensors. This display network will be designed and implemented to be open to applications and content from many sources and thus provide the foundation for work on a new global communications medium for information access and interaction."

Members of the PD-Net consortium showed a couple of demos at the 2013 ACM International Joint Conference on Pervasive and Ubiquitous Computing (Ubicomp 2013).
Social media platforms such as Flicker, Twitter, Instagram, and Facebook have opened up new possibilities for providing content on large public displays. Integrating interactive elements in a public display, such as (virtual) Keyboards and Webcams, can additionally stimulate in-situ content production. Both social media content and such in-situ content are cheap to produce, always fresh, and potentially community sourced, thus increasing relevance for passersby. However, not all social media applications and content entries may be appropriate in a particular display setting and showing user contributed content on public displays requires new forms of content control and scheduling. In this demo we show: 1) a control interface for display owners to manage the overall behaviour of their displays, and 2) post-moderation mechanisms for controlling and removing potentially inappropriate user contributed content from public displays displays. The control interface and moderation mechanisms are designed for a university environment and were inspired by two short pilot test deployments and a focus group with the university socials.
As displays in public space are augmented with sensors, such as the Kinect, they enable passersby to interact with the content on the screen. As of today, feedback on the user action in such environments is usually limited to the visual channel. However, we believe that more immediate and intense forms, in particular haptic feedback, do not only increase the user experience, but may also have a strong impact on user attention and memorization of the content encountered during the interaction. Haptic feedback can today be achieved through vibration on the mobile phone, which is strongly dependent on the location of the device. We envision that fabrics, such as underwear, can in the future be equipped with electrical muscle stimulation, thus providing a more natural and direct way of haptic feedback. In this demo we aim to showcase the potential of applying electrical muscle stimulation as direct haptic feedback during interaction in public spaces in the context of a Kinect-based game for public displays.

Nigel Davies, Rui Jose, Nemanja Memarovic, Ivan Elhart, and Sarah Clinch organize a workshop on developing publications for public display networks. With significant reductions in the cost of large LCD screens, public displays are proliferating in urban spaces. It is not hard to imagine that they will soon be networked and connected over the Internet, constituting a novel and powerful communication medium pervasive display networks open to a wide range of applications and content. The aim of the workshop is to bring together experts from a variety of domains, i.e., UbiComp, HCI, Software Engineering, User Experience, and Public Displays to exchange ideas and discuss opportunities and challenges in creating applications for pervasive display networks. Overall, the goal of the workshop is to setup a meeting point for the people working on pervasive display networks as well as to create a common understanding and set the goals and challenges for further research on the topic of developing applications for pervasive display networks.

The Third International Symposium on Pervasive Displays will take place in June 2014 at the University of Copenhagen in Copenhagen, Denmark. The event will bring together researchers from various disciplines with a common interest on the opportunities and challenges raised by the emergence of pervasive display systems as a new communication medium for public and semi-public spaces. As a targeted topic venue, Pervasive Displays offers participants a unique opportunity to network with a diverse but focused research community, resulting in an extremely lively event with all the energy and excitement that characterizes the emergence of a new research community. Previous Symposia were organized by the University of Minho in Porto, Portugal (2012) and by Google, Mountain View, CA, USA (2013).

On June 4-5 2013, the Second International Symposium on Pervasive Displays (PerDis’13) was hosted by Roy Want and Bill Schilit at Google in Mountain View (US). During the conference a set of 27 exciting papers was presented, 6 including authors from PD-Net.
All papers can be found on the publication page.
The PerDis Symposium series will continue in 2014, being hosted by Sebastian Boring in Copenhagen. Aaron Quigley will be the TPC chair.

Information on the PD-Net Ethics Framework are now available on the project website (read more).
Research involving public displays often faces the need to study the effects of a deployment in the wild. While many organizations have institutionalized processes for ensuring ethical compliance of such human subject experiments, these may fail to stimulate sufficient awareness for ethical issues among all project members. Some organizations even require such assessments only for medical research, leaving computer scientists without any incentive to consider and reflect on their study design and data collection practices. Faced with similar problems in the context of the EU-funded PD-Net project, we have implemented a step-by-step ethics process that aims at providing structured yet light-weight guidance to all project members, both stimulating the design of ethical user studies, as well as providing continuous documentation.
Here, we describe our process and our 3 years of experience using it. All materials are publicly available and we encourage other projects in the area of public displays, and beyond, to adopt them to suit their particular needs and to eventually re-share their experiences and material through this website. If you adopt any of the documents presented in your project we would appreciate if you reference our corresponding publication as follows:
