Student response systems (SRS) are a popular and effective tool to promote active learning on site, improving student engagement and attention, motivation and learning performance. Traditionally, SRS are designed for on-site settings. However, the safety measures in relation to the recent COVID-19 pandemic result in remote teaching at an unprecedented scale, with online courses becoming the rule. In this paper, we discuss the utilization of interactive SRS in such remote settings for which they initially were not designed. Over the last term, we conducted several empirical surveys across different groups of Computer Science students on undergraduate and postgraduate levels, and covering a broad age spectrum. The results indicate that, while common interactive features of videoconferencing tools, such as chat or polls, are well appreciated, there is still a need for dedicated SRS with game-based elements and feature sets beyond standard multiple-choice questions.

Social robots have an enormous potential for educational applications and allow for cognitive outcomes that are similar to those with human involvement. Remotely controlling a social robot to interact with students and peers in an immersive fashion opens up new possibilities for instructors and learners alike. Using immersive approaches can promote engagement and have beneficial effects on remote lesson delivery and participation. However, the performance and power consumption associated with the involved devices are often not sufficiently contemplated, despite being particularly important in light of sustainability considerations. The contributions of this research are thus twofold. On the one hand, we present telepresence solutions for a social robot’s location-independent operation using (a) a virtual reality headset with controllers and (b) a mobile augmented reality application. On the other hand, we perform a thorough analysis of their power consumption and system performance, discussing the impact of employing the various technologies. Using the QTrobot as a platform, direct and immersive control via different interaction modes, including motion, emotion, and voice output, is possible. By not focusing on individual subsystems or motor chains, but the cumulative energy consumption of an unaltered robot performing remote tasks, this research provides orientation regarding the actual cost of deploying immersive robotic telepresence solutions.

Social robots have an enormous potential for educational applications, allowing cognitive outcomes similar to those with human involvement. Enabling instructors and learners to directly control a social robot and immersively interact with their students and peers opens up new possibilities for effective lesson delivery and better participation in the classroom. This paper proposes the use of immersive technologies to promote engagement in remote educational settings involving robots. In particular, this research introduces a telepresence framework for the location-independent operation of a social robot using a virtual reality headset and controllers. Using the QTrobot as a platform, the framework supports the direct and immersive control via different interaction modes including motion, emotion and voice output. Initial tests involving a large audience of educators and students validate the acceptability and applicability to interactive classroom scenarios.

This paper introduces the CollaTrEx framework for collaborative context-aware mobile exploration and training. It is particularly designed for the in-situ collaboration within groups of learners performing together diverse educational activities to explore their environment in a fun and intuitive way. Aside from employing both absolute and relative spatio-temporal context for determining the available activities, different buffering levels are an important conceptual feature supporting seamless collaboration in spite of temporary connection losses or when in remote areas. CollaTrEx comprises a prototypical front-end implementation for tablet devices, as well as a web-based back-end solution for the creation and management of activities which can be easily extended to accommodate both future technologies and novel activity types.

In distributed collaborative document authoring environments, the preservation of a globally consistent data state is an important factor. However, synchronization conflicts are unavoidable and constitute a serious challenge. Our advanced compound document system provides the basis for a novel consistency management approach, in particular regarding autonomous conflict detection and resolution. Current techniques to achieve and maintain global consistency in distributed environments almost exclusively utilize file-based data structures, thereby limiting the accessibility to supplementary information. In this paper, we present a layer-based consistency management approach harnessing a fine-granular, graph-based data representation and relational dependencies. We discuss the application of concurrent conflict detection and resolution modules designed to preserve user intent while avoiding workflow interruptions. The combination of an advanced compound document system with autonomous, layer-based consistency management has the potential to notably increase reliability and facilitate the collaborative authoring process.

Collective decision-making is a key concern for every social group; the clarity, effectiveness and participatory characteristics of the process are central to democratic societies and procedures.Networked computer systems in general and the increasing attention to social aspects in their purpose and design offer the individual novel means for participation, but also entail specific systemic problems. These can be either variations of existing general sociological and political issues, or arising also from the system’s characteristic technical design and structure. This article provides an overview of systems for collective and dynamic decision-making with their peculiarities, focusing on the three core interacting aspects: anonymity, immediacy and electoral delegation.

This paper proposes a novel approach for enhancing document excerpts with semantic structures that are treated as first-class citizens, i.e., integrated at the system level. Providing support for semantics at the system level is in contrast with existing solutions that implement semantics as an add-on using intermediate descriptors. A framework and a toolset inspired by the Semantic Web Stack have been integrated into the Snippet System, an operating system environment that provides support for fine-grained representation and management of documents and the relationships that exist between arbitrary excerpts. The high granularity, combined with native support for semantics, is leveraged to alleviate some of the existing personal information management problems in terms of content retrieval and document engineering. The resulting framework offers some inherent advantages in terms of refined resource description, content and knowledge reuse along with self-contained documents that retain their metadata without depending on intermediate entities.

When dealing with dynamic large-scale topologies such as those underlying Peer-to-Peer (P2P) Distributed Virtual Environments (DVEs), one inescapably reaches the point where either: a) simulations lack human behaviour and assessment or where b) practical experiments on a small scale do not yield significant results. The restrictions resulting from the separation of simulation and testbed environments hinder a comprehensive assessment and efficient development of adaptive algorithms and techniques for DVEs as they are investigated in our HyperVerse research project. In this paper, we present a hybrid evaluation system designed to combine the advantages of simulations and testbeds. The proposed infrastructure exhibits great flexibility particularly alluring in view of the multitude of potential research in the context of DVEs.

The vision of a '3D Web' as a combination of massive online virtual environments and today's WWW currently attracts a lot of attention. While it provides a multitude of opportunities, the realisation of this vision on a global scale poses severe technical challenges. This paper points out some of the major challenges and highlights key concepts of an infrastructure that is being developed in order to meet them. Among these concepts, special emphasis is put on the usage of a two-tier Peer-to-Peer approach, the implementation of Torrent-based data distribution, and the development of a graded consistency notion. The paper presents the current state of a prototype implementation that is being developed in order to validate these concepts and evaluate alternative approaches.
