Our body is central to what we define as our self. The mental representation of our physical appearance, often called body image, can have a great influence on our psychological health. Given the increase in body mass index worldwide and the societal pressure to conform to body ideals, it is important to gain a better understanding of the nature of body representations and factors that play a role in body size estimation tasks. This doctoral thesis takes a multifaceted approach for investigating the role of different visual cues in the estimation of own body size and shape by using a variety of experimental methods and novel state-of-the-art computer graphics methods. Two visual cues were considered: visual perspective and identity cues in the visual appearance of a body (shape, and color-information), as well as their interactions with own body size and gender. High ecological validity was achieved by testing body size estimation in natural settings, when looking into a mirror, and by generating biometrically plausible virtual bodies based on 3D body scans and statistical body models, and simulating real-world scenarios in immersive virtual reality.

Humans always wanted to go faster and higher than their own legs could carry them. This led them to invent numerous types of vehicles to move fast over land, water and air. As training how to handle such vehicles and testing new developments can be dangerous and costly, vehicle motion simulators were invented. Motion-based simulators in particular, combine visual and physical motion cues to provide occupants with a feeling of being in the real vehicle. While visual cues are generally not limited in amplitude, physical cues certainly are, due to the limited simulator motion space. A motion cueing algorithm (MCA) is used to map the vehicle motions onto the simulator motion space. This mapping inherently creates mismatches between the visual and physical motion cues. Due to imperfections in the human perceptual system, not all visual/physical cueing mismatches are perceived. However, if a mismatch is perceived, it can impair the simulation realism and even cause simulator sickness. For MCA design, a good understanding of when mismatches are perceived, and ways to prevent these from occurring, are therefore essential. In this thesis a data-driven approach, using continuous subjective measures of the time-varying Perceived Motion Incongruence (PMI), is adopted. PMI in this case refers to the effect that perceived mismatches between visual and physical motion cues have on the resulting simulator realism. The main goal of this thesis was to develop an MCA-independent off-line prediction method for time-varying PMI during vehicle motion simulation, with the aim of improving motion cueing quality. To this end, a complete roadmap, describing how to measure and model PMI and how to apply such models to predict and minimize PMI in motion simulations is presented. Results from several human-in-the-loop experiments are used to demonstrate the potential of this novel approach.

Technologische Fortschritte in der Computergrafik, dem dreidimensionalen Scannen und in Motion-Tracking-Technologien haben zu einem erhöhten Einsatz von Selbst-Avataren in immersiven virtuellen Realitäten (VR) beigetragen. Selbst-Avatare werden zum Beispiel in den Bereichen Visualisierung und Simulation, aber auch in klinischen Anwendungen oder für Unterhaltungszwecke eingesetzt. Deshalb ist es wichtig neue Erkenntnisse über die Wahrnehmung des eigenen Körpers, des Selbst-Avatars und der räumlichen Wahrnehmung des Benutzers zu gewinnen, sowie den Einfluss des Selbst-Avatars auf die räumliche Wahrnehmung in der virtuellen Welt zu untersuchen. Mit Hilfe von moderner VR-Technologie habe ich untersucht wie Veränderungen des Selbst-Avatars die Wahrnehmung des eigenen Körpers und des Raumes verändern. Die Ergebnisse zeigen, dass Selbst-Avatare nicht genau die gleichen Dimensionen wie der Körper des Benutzers haben müssen, damit sich der Benutzer mit seinem Selbst-Avatar identifizieren kann.

More than 200 years after the first speaking machine, we are accustomed to voices that speak from any- and everywhere. We interact daily with voices that emit from house alarm systems, cars, telephones, and digital assistants, such as Alexa and Google Home. However, vocal events still have the capacity to raise age-old questions about the human, the animal, the machine, and the spiritual-or in non-metaphysical terms-questions about identity and authenticity. In The Oxford Handbook of Voice Studies, contributors look to the metaphorical voice as well as the clinical understanding of the vocal apparatus to answer the seemingly innocuous question: What is voice? From a range of disciplines including the humanities, biology, culture, and technology studies, contributors draw on the unique methodologies and values each has at hand to address the uses, meanings, practices, theories, methods, and sounds of the voice. Together, they assess the ways that discipline-specific, ontological, and epistemological assumptions of voice need to shift in order to take the findings of other fields into account. This Handbook thus enables a lively discussion as multifaceted and complex as the voice itself has proven to be.
