The Visual Social Distancing Problem
One of the main and most effective measures to contain the recent viral
outbreak is the maintenance of the so-called Social Distancing (SD). To comply
with this constraint, workplaces, public institutions, transports and schools
will likely adopt restrictions over the minimum inter-personal distance between
people. Given this actual scenario, it is crucial to massively measure the
compliance to such physical constraint in our life, in order to figure out the
reasons of the possible breaks of such distance limitations, and understand if
this implies a possible threat given the scene context. All of this, complying
with privacy policies and making the measurement acceptable. To this end, we
introduce the Visual Social Distancing (VSD) problem, defined as the automatic
estimation of the inter-personal distance from an image, and the
characterization of the related people aggregations. VSD is pivotal for a
non-invasive analysis to whether people comply with the SD restriction, and to
provide statistics about the level of safety of specific areas whenever this
constraint is violated. We then discuss how VSD relates with previous
literature in Social Signal Processing and indicate which existing Computer
Vision methods can be used to manage such problem. We conclude with future
challenges related to the effectiveness of VSD systems, ethical implications
and future application scenarios.Comment: 9 pages, 5 figures. All the authors equally contributed to this

Learning in Conferences
{Excerpt} The true value of a conference lies in its effects on participants. Conferences are to generate and share knowledge that impacts behavior and links to results: this will not happen if the state-of-the-art of conference evaluation remains immature and event planners do not shine a light on the conditions for learning outcomes
Meetings and Meeting Modeling in Smart Environments
In this paper we survey our research on smart meeting rooms and its relevance for augmented reality meeting support and virtual reality generation of meetings in real time or off-line. The research reported here forms part of the European 5th and 6th framework programme projects multi-modal meeting manager (M4) and augmented multi-party interaction (AMI). Both projects aim at building a smart meeting environment that is able to collect multimodal captures of the activities and discussions in a meeting room, with the aim to use this information as input to tools that allow real-time support, browsing, retrieval and summarization of meetings. Our aim is to research (semantic) representations of what takes place during meetings in order to allow generation, e.g. in virtual reality, of meeting activities (discussions, presentations, voting, etc.). Being able to do so also allows us to look at tools that provide support during a meeting and at tools that allow those not able to be physically present during a meeting to take part in a virtual way. This may lead to situations where the differences between real meeting participants, human-controlled virtual participants and (semi-) autonomous virtual participants disappear
The phone as a tool for combining online and offline social activity – teenagers’ phone access to an online community
We have analyzed two months of log data and 100 surveys on the phone use of a Swedish online community for teenagers to investigate the mobile use of an established online service. This shows that the phone use mostly takes place during times of the day when teenagers have social time and the use is not influenced by the availability of a computer. The phone makes the community access more private compared to the computer, but teens do share the use when they want to. The cell phone bridges the online and offline social communities and allows teens to participate in both at the same time. The online community is not only a place for social activity online, it is also a social activity offline that is carried out face-to-face with friends. The cell phone thus was a tool for the teens to combine their participation in the online and the offline world
Startup communities: notes on the sociality of tech-entrepreneurs in Manchester
In this contribution I explore the conflicting moralities and practices of technology entrepreneurship through the lenses of Mary Douglas’ Grid-Group Cultural Theory. Starting from the distinction between communitarian, individualistic and hierarchical culture, I explore my empirical material drawn from ethnographic fieldwork in Manchester, UK. In particular, I describe the sociality of young male tech-entrepreneurs at networking events, ‘coffices’ and coworkspaces around an urban ‘creative quarter’. I argue that ‘startup communities’ simultaneously encourage individualistic market-competition, contribute to feelings of local group-belonging and are narrative constructions promoted by entrepreneurs, corporations and the State.Universidad de Sevill
SALSA: A Novel Dataset for Multimodal Group Behavior Analysis
Studying free-standing conversational groups (FCGs) in unstructured social
settings (e.g., cocktail party ) is gratifying due to the wealth of information
available at the group (mining social networks) and individual (recognizing
native behavioral and personality traits) levels. However, analyzing social
scenes involving FCGs is also highly challenging due to the difficulty in
extracting behavioral cues such as target locations, their speaking activity
and head/body pose due to crowdedness and presence of extreme occlusions. To
this end, we propose SALSA, a novel dataset facilitating multimodal and
Synergetic sociAL Scene Analysis, and make two main contributions to research
on automated social interaction analysis: (1) SALSA records social interactions
among 18 participants in a natural, indoor environment for over 60 minutes,
under the poster presentation and cocktail party contexts presenting
difficulties in the form of low-resolution images, lighting variations,
numerous occlusions, reverberations and interfering sound sources; (2) To
alleviate these problems we facilitate multimodal analysis by recording the
social interplay using four static surveillance cameras and sociometric badges
worn by each participant, comprising the microphone, accelerometer, bluetooth
and infrared sensors. In addition to raw data, we also provide annotations
concerning individuals' personality as well as their position, head, body
orientation and F-formation information over the entire event duration. Through
extensive experiments with state-of-the-art approaches, we show (a) the
limitations of current methods and (b) how the recorded multiple cues
synergetically aid automatic analysis of social interactions. SALSA is

MetaMosque – Envisioning the Mosque as a Virtual Public Space
Historically, the mosque was not only a space for a communal prayer but also a place for building a community. Today, however, with conflicts and diseases fragmenting society, people are less able to gather physically in large spaces. Out of necessity, people rely on technology to get together and interact virtually. In this context, my research challenges the notion of the mosque as a physical space, proposing, instead, its extension into virtual space. Recent global events pose the question: Can the metaverse offer an opportunity for the mosque to reassert itself as a public space. I propose that a MetaMosque can facilitate vital, spiritual and communal functions—similar to a physical mosque—creating a sense of belonging and unity across social and physical boundaries. Rather than replacing the traditional mosque\u27s capabilities, the MetaMosque attempts to extend them, forming a virtual public space and encouraging a more accessible and inclusive virtual society
