Grundsatzpapier des DfI gegen Diskrimierung und zur sozialen Verantwortung

Wir handeln

  • Wir nehmen unsere Mitverantwortung für die Gesellschaft, in der wir leben, aktiv wahr.
  • In einer vernetzten Welt lassen sich Herausforderungen nur in einer friedlichen internationalen Zusammenarbeit lösen. Jeder Form von Nationalismus treten wir entschieden entgegen.
  • Wir setzen uns dafür ein, dass Menschen nicht wegen ihrer Hautfarbe, Herkunft, Religion, Geschlecht oder sexueller Orientierung benachteiligt oder diffamiert werden.
  • Wir sind nicht bereit, Diskussionen zu tolerieren, die faktenfrei oder auf der Basis von Ressentiments geführt werden.

Was tun bei Diskriminierung?

Ignorieren und verdrängen Sie Diskriminierung nicht, sondern setzen Sie sich zur Wehr:

Abstract:
In contemp orary society\, social connectedness is increasingly at risk due to shifts in both professional and personal domains\, such as remote work and globa lization-driven mobility. This trend has profound social consequences\, co ntributing to heightened levels of loneliness and social isolation\, which in turn negatively impact mental and physical well-being. Multi-user virt ual reality (VR) emerges as a promising technology to address this challen ge by providing immersive and interactive environments for remote social i nteractions. However\, despite its potential\, current multi-user VR syste ms often fail to foster a compelling sense of "being with another" - the s o-called social presence.
This dissertation aims to systematically in vestigate how social presence—the psychological experience of perceiving a technologically mediated counterpart as real—can be enhanced in multi -user VR. Social presence is crucial for successful technology-mediated in teractions\, as it correlates with positive outcomes such as trust\, enjoy ment\, and naturalistic social behavior. Existing research in this domain primarily focuses on other communication technologies\, leaving a gap in u nderstanding the unique challenges posed by multi-user VR environments. In particular\, the influence of user representations and their properties r emains underexplored\, despite being central to VR-mediated social interac tions.
To address this research gap\, this dissertation examines thre e key properties of user representations that may enhance social presence in multi-user VR: (1) behavioral realism\, (2) visualizing mental states\, and (3) social touch. First\, this work explores whether avatars with rea listic facial expressions and gestures can foster a stronger sense of soci al presence. Second\, given that access to an interaction partner’s ment al state is integral to social presence\, the study investigates whether r eal-time visualization of cognitive load derived from biosensory feedback can enhance perceived connectedness. Third\, the dissertation examines the potential of integrating haptic social touch\, such as handshakes and hig h-fives\, to increase social presence. The research follows a human-center ed design approach\, employing requirement analyses through interviews and surveys\, followed by controlled lab experiments assessing social presenc e in dyadic user interactions. Findings indicate that behavioral realism\, particularly through eye and mouth movements\, significantly enhances soc ial presence. Cognitive load visualizations further foster social presence \, particularly in tasks with lower cognitive demand. Additionally\, hapti c feedback in social touch not only increases social presence but also red uces negative affect\, reinforcing its potential to support social interac tions in VR.
By systematically identifying effective design strategie s\, this dissertation provides actionable guidelines for enhancing social presence in multi-user VR\, contributing to the broader discourse on lever aging technology to mitigate social isolation in an increasingly digital w orld.

Abstract:
The large-scale introduction of automa ted vehicles on public roads is an ambitious and challenging goal. This te chnology aims to significantly contribute to increased traffic safety and comfort\, while also serving as the foundation for further innovative mobi lity concepts. However\, one of the most significant challenges in introdu cing such systems is ensuring their compliance with local regulatory requi rements\, since it is essential that these systems function correctly and safely within complex real-world environments without a human fall-back op tion.
Due to the complexity of the systems and their environment\, th e driving function or the automated vehicle is systematically tested in sp ecific scenarios. However\, the availability of an extensive dataset with diverse scenarios is a critical prerequisite\, which can be defined based on different data sources. The collection of traffic data in the real worl d\, using either vehicles or (quasi-) stationary infrastructure\, represen ts a particularly valuable source\, as it realistically reflects the behav iour of human road users and also includes atypical behaviour or even crit ical conflicts between participants. Specifically\, infrastructure-based t raffic data collection allows a detailed description of scenarios and\, du e to continuous data collection\, the identification of rare phenomena. Ho wever\, this continuous stream of traffic data must be systematically proc essed to create a comprehensive collection of scenarios.
This thesis addresses this issue and presents a methodology for representing traffic d ata collected in the real world based on scenarios and their systematic id entification from real-world traffic data. A hierarchical data model is us ed for this purpose\, which semantically describes traffic data at four le vels of abstraction. Various approaches to defining and identifying phenom ena at those abstraction levels using real-traffic data are presented. In particular\, the level of primitives is motivated and a methodology is pro posed that allows traffic data to be represented in terms of primitives an d\, based on them\, the derivation of manoeuvres. Based on this\, a method ology is presented for the systematic definition and extraction of scenari os using ontologies. The different methods are integrated into a modular p latform that enables the continuous identification and analysis of scenari os in real-world traffic data.
The procedures and methods presented i n this work are individually evaluated using real-world problems. Overall\ , the results show that the proposed methodology enables the systematic id entification and representation of scenarios from real-world traffic data\ , thereby contributing to the compilation of a comprehensive knowledge bas e of scenarios. Furthermore\, the results highlight the versatility of the proposed methodologies\, demonstrating their application to a range of re search questions. The exemplary use of ontologies may also serve as a foun dation for future work\, particularly within the domain of artificial inte lligence research.
