Influence of augmented humans in online interactions during voting events
The advent of the digital era provided a fertile ground for the development
of virtual societies, complex systems influencing real-world dynamics.
Understanding online human behavior and its relevance beyond the digital
boundaries is still an open challenge. Here we show that online social
interactions during a massive voting event can be used to build an accurate map
of real-world political parties and electoral ranks. We provide evidence that
information flow and collective attention are often driven by a special class
of highly influential users, that we name "augmented humans", who exploit
thousands of automated agents, also known as bots, for enhancing their online
influence. We show that augmented humans generate deep information cascades, to
the same extent of news media and other broadcasters, while they uniformly
infiltrate across the full range of identified groups. Digital augmentation
represents the cyber-physical counterpart of the human desire to acquire power
within social systems.Comment: 11 page
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
Spotting political social bots in Twitter: A use case of the 2019 Spanish general election
While social media has been proved as an exceptionally useful tool to
interact with other people and massively and quickly spread helpful
information, its great potential has been ill-intentionally leveraged as well
to distort political elections and manipulate constituents. In the paper at
hand, we analyzed the presence and behavior of social bots on Twitter in the
context of the November 2019 Spanish general election. Throughout our study, we
classified involved users as social bots or humans, and examined their
interactions from a quantitative (i.e., amount of traffic generated and
existing relations) and qualitative (i.e., user's political affinity and
sentiment towards the most important parties) perspectives. Results
demonstrated that a non-negligible amount of those bots actively participated
in the election, supporting each of the five principal political parties
Challenges in Complex Systems Science
FuturICT foundations are social science, complex systems science, and ICT.
The main concerns and challenges in the science of complex systems in the
context of FuturICT are laid out in this paper with special emphasis on the
Complex Systems route to Social Sciences. This include complex systems having:
many heterogeneous interacting parts; multiple scales; complicated transition
laws; unexpected or unpredicted emergence; sensitive dependence on initial
conditions; path-dependent dynamics; networked hierarchical connectivities;
interaction of autonomous agents; self-organisation; non-equilibrium dynamics;
combinatorial explosion; adaptivity to changing environments; co-evolving
subsystems; ill-defined boundaries; and multilevel dynamics. In this context,
science is seen as the process of abstracting the dynamics of systems from
data. This presents many challenges including: data gathering by large-scale
experiment, participatory sensing and social computation, managing huge
distributed dynamic and heterogeneous databases; moving from data to dynamical
models, going beyond correlations to cause-effect relationships, understanding
the relationship between simple and comprehensive models with appropriate
choices of variables, ensemble modeling and data assimilation, modeling systems
of systems of systems with many levels between micro and macro; and formulating
new approaches to prediction, forecasting, and risk, especially in systems that
can reflect on and change their behaviour in response to predictions, and
systems whose apparently predictable behaviour is disrupted by apparently
unpredictable rare or extreme events. These challenges are part of the FuturICT
agenda
Virtual Meeting Rooms: From Observation to Simulation
Much working time is spent in meetings and, as a consequence, meetings have become the subject of multidisciplinary research. Virtual Meeting Rooms (VMRs) are 3D virtual replicas of meeting rooms, where various modalities such as speech, gaze, distance, gestures and facial expressions can be controlled. This allows VMRs to be used to improve remote meeting participation, to visualize multimedia data and as an instrument for research into social interaction in meetings. This paper describes how these three uses can be realized in a VMR. We describe the process from observation through annotation to simulation and a model that describes the relations between the annotated features of verbal and non-verbal conversational behavior.\ud
As an example of social perception research in the VMR, we describe an experiment to assess human observersâ accuracy for head orientation
Integrating passive ubiquitous surfaces into human-computer interaction
Mobile technologies enable people to interact with computers ubiquitously. This dissertation investigates how ordinary, ubiquitous surfaces can be integrated into human-computer interaction to extend the interaction space beyond the edge of the display. It turns out that acoustic and tactile features generated during an interaction can be combined to identify input events, the user, and the surface. In addition, it is shown that a heterogeneous distribution of different surfaces is particularly suitable for realizing versatile interaction modalities. However, privacy concerns must be considered when selecting sensors, and context can be crucial in determining whether and what interaction to perform.Mobile Technologien ermöglichen den Menschen eine allgegenwĂ€rtige Interaktion mit Computern. Diese Dissertation untersucht, wie gewöhnliche, allgegenwĂ€rtige OberflĂ€chen in die Mensch-Computer-Interaktion integriert werden können, um den Interaktionsraum ĂŒber den Rand des Displays hinaus zu erweitern. Es stellt sich heraus, dass akustische und taktile Merkmale, die wĂ€hrend einer Interaktion erzeugt werden, kombiniert werden können, um Eingabeereignisse, den Benutzer und die OberflĂ€che zu identifizieren. DarĂŒber hinaus wird gezeigt, dass eine heterogene Verteilung verschiedener OberflĂ€chen besonders geeignet ist, um vielfĂ€ltige InteraktionsmodalitĂ€ten zu realisieren. Bei der Auswahl der Sensoren mĂŒssen jedoch Datenschutzaspekte berĂŒcksichtigt werden, und der Kontext kann entscheidend dafĂŒr sein, ob und welche Interaktion durchgefĂŒhrt werden soll
The Design of Compelling Narratives
While storytelling is an essential form of communication and has been used to help humans make sense of the world and prepare for the future for thousands of years, compelling narratives are designed storytelling systems that encourage the audience to get involved and make active thought and behavioral change. Another significant aspect of compelling narrative design is that they are not resolute. While stories have definite endings, the end of a compelling narrative should be a âcall to actionâ, an opportunity to engage further and invest time, effort, or aid back into the narrativeâs cause. The challenge for designers is how can we use this design process to leverage the educational, entertaining, and empathic nature of storytelling to change behavior and prompt meaningful interactions?
Prezolution is a political campaign game, set in America in the year 2040, which encourages non-partisan political discussion and problem solving. In the game, the traditional two-party system has disappeared, leaving and opportunity for much more diverse candidates and their ideas to emerge in order to help solve more complex issues than we have ever faced as a country before. The extension of the board game to the online platform changes the experience from an individual story into a larger compelling narrative system. When we can bring together diverse audiences to share their values, ideas, and visions for our future, we may find common goals that unite us and inspire active investment in shaping our future together
Internet of robotic things : converging sensing/actuating, hypoconnectivity, artificial intelligence and IoT Platforms
The Internet of Things (IoT) concept is evolving rapidly and influencing newdevelopments in various application domains, such as the Internet of MobileThings (IoMT), Autonomous Internet of Things (A-IoT), Autonomous Systemof Things (ASoT), Internet of Autonomous Things (IoAT), Internetof Things Clouds (IoT-C) and the Internet of Robotic Things (IoRT) etc.that are progressing/advancing by using IoT technology. The IoT influencerepresents new development and deployment challenges in different areassuch as seamless platform integration, context based cognitive network integration,new mobile sensor/actuator network paradigms, things identification(addressing, naming in IoT) and dynamic things discoverability and manyothers. The IoRT represents new convergence challenges and their need to be addressed, in one side the programmability and the communication ofmultiple heterogeneous mobile/autonomous/robotic things for cooperating,their coordination, configuration, exchange of information, security, safetyand protection. Developments in IoT heterogeneous parallel processing/communication and dynamic systems based on parallelism and concurrencyrequire new ideas for integrating the intelligent âdevicesâ, collaborativerobots (COBOTS), into IoT applications. Dynamic maintainability, selfhealing,self-repair of resources, changing resource state, (re-) configurationand context based IoT systems for service implementation and integrationwith IoT network service composition are of paramount importance whennew âcognitive devicesâ are becoming active participants in IoT applications.This chapter aims to be an overview of the IoRT concept, technologies,architectures and applications and to provide a comprehensive coverage offuture challenges, developments and applications
