Multipoint videoconferencing in particular has become a favored means for web-based forms of remote communication and collaboration without physical copresence. Taking the recent mainstreaming of videoconferencing as its point of departure, this anthology examines the complex mediality of this new form of social interaction. Connecting theoretical reflection with material case studies, the contributors question practices, politics and aesthetics of videoconferencing and the specific meanings it acquires in different historical, cultural and social contexts.

Lab: Checkworthiness, Subjectivity, Political Bias, Factuality, and Authority T2 - Advances in Information Retrieval : 45th European Conference on Information Retrieval, ECIR 2023, Dublin, Ireland, April 2–6, 2023, Proceedings, Part III N2 - The five editions of the CheckThat! lab so far have focused on the main tasks of the information verification pipeline: check-worthiness, evidence retrieval and pairing, and verification. The 2023 edition of the lab zooms into some of the problems and - for the first time - it offers five tasks in seven languages (Arabic, Dutch, English, German, Italian, Spanish, and Turkish): Task 1 asks to determine whether an item, text or a text plus an image, is check-worthy; Task 2 requires to assess whether a text snippet is subjective or not; Task 3 looks for estimating the political bias of a document or a news outlet; Task 4 requires to determine the level of factuality of a document or a news outlet; and Task 5 is about identifying authorities that should be trusted to verify a contended claim.

Photographs, illustrations, infographics, data visualizations, and general images help convey complex topics to a wide audience. The way that visual artifacts influence how readers form an opinion beyond the text is an important issue to research, but there are few works about this topic. In this context, we research the persuasive, emotional and memorable dimensions of data visualizations and illustrations in journalistic storytelling for long-form articles. We conducted a user study and compared the effects which data visualizations and illustrations have on changing attitude towards a presented topic. While visual representations are usually studied along one dimension, in this experimental study, we explore the effects on readers' attitudes along three: persuasion, emotion, and information retention. By comparing different versions of the same article, we observe how attitudes differ based on the visual stimuli present, and how they are perceived when combined. Results indicate that the narrative using only data visualization elicits a stronger emotional impact than illustration-only visual support, as well as a significant change in the initial attitude about the topic. Our findings contribute to a growing body of literature on how visual artifacts may be used to inform and influence public opinion and debate. We present ideas for future work to generalize the results beyond the domain studied, the water crisis.

Using an example from the chemistry classroom, we illustrate how these technologies can enhance education and learning by fostering collaboration and shared understanding.Despite the vast potential of XR and VR, many of their applications remain isolated. Currently, sharing experiences often involves streaming onto a screen or verbal explanations, which can leave individuals feeling excluded if they are not directly involved. Even when multiple users wear VR or XR headsets, shared experiences are often limited to specific contexts like multiplayer VR games. Unfortunately, in domains such as education, work, or collaborative learning, these technologies are often underutilized.To bridge this gap, our study developed a prototype that leverages the eye-tracking and hand-tracking capabilities of the HoloLens2. This prototype enables collaborative interactions with 3D elements in an XR environment. By tracking participants' gaze within the XR scene, users can easily identify the element they are currently viewing. Through eye control and pinch gestures, users can manipulate digital content on the XR plane. When working within the same XR environment, users seamlessly share interactions and information, fostering a unified and collaborative experience with holograms.The current prototype is tailored to explore the intricate molecular details of sugar molecules within a collaborative XR environment. Teams of users can collectively delve into molecules such as fructose, glucose, galactose, and mannose, gaining deeper insights into their unique characteristics. Through interactions like eye-tracking and pinch gestures, users can directly interact with holographic 3D representations of these molecules. The prototype's user interface intuitively indicates which user is interacting with or observing each 3D object within the XR environment. Unlike conventional controllers, this prototype employs hand-tracking technology, enabling users to effortlessly navigate the XR interface using natural hand movements. This approach delivers an immersive and dynamic learning experience that surpasses traditional teaching methods, fostering heightened engagement and deeper understanding among learners. To assess the functionality and cognitive impact of the XR interface prototype, 19 participants were recruited for evaluation. Criteria for participant selection ensured they lacked prior knowledge or involvement in chemistry or related fields concerning sugar molecules. Following a brief introduction to the prototype's interaction patterns and eye calibration, participants engaged in testing across diverse learning scenarios. Initial survey findings suggest participants could swiftly distinguish between monosaccharides like glucose, fructose, galactose, and mannose based on their three-dimensional structures. However, results regarding gaze interaction evaluation are inconclusive and necessitate further experimentation.
