VR/AR input devices and tracking. - In: Virtual and augmented reality (VR/AR), (2022), S. 107-148
How do Virtual Reality (VR) and Augmented Reality (AR) systems recognize the actions of users? How does a VR or AR system know where the user is? How can a system track objects in their movement? What are proven input devices for VR and AR that increase immersion in virtual or augmented worlds? What are the technical possibilities and limitations? Based on fundamentals, which explain terms like degrees of freedom, accuracy, repetition rates, latency and calibration, methods are considered that are used for continuous tracking or monitoring of objects. Frequently used input devices are presented and discussed. Finally, examples of special methods such as finger and eye tracking are discussed.
VR/AR output devices. - In: Virtual and augmented reality (VR/AR), (2022), S. 149-200
This chapter discusses output devices and technologies for Virtual Reality (VR) and Augmented Reality (AR). The goal of using output devices is to enable the user to dive into the virtual world or to perceive the augmented world. Devices for visual output play a crucial role here, they are of central importance for the use of VR and AR. First and foremost, Head-Mounted Displays (HMD) must be mentioned, the different types of which are discussed in detail here. However, VR also uses different forms of stationary displays, which are another major topic of this chapter. Finally, output devices for other senses are reviewed, namely acoustic and haptic outputs.
Augmented reality. - In: Virtual and augmented reality (VR/AR), (2022), S. 291-329
This chapter covers specific topics of Augmented Reality (AR). After an introduction to the basic components and a review of the different types of AR, the following sections explain the individual components in more detail, as far as they were not already part of previous chapters. This includes in particular the different manifestations of registration, since these are of central importance for an AR experience. Furthermore, special AR techniques and interaction types are introduced before discussing individual application areas of AR. Then, Diminished Reality (DR), the opposite of AR, is discussed, namely the removal of real content. Finally, Mediated Reality, which allows for altering reality in any form, including the combination of AR and DR, will be discussed.
Authoring of VR/AR applications. - In: Virtual and augmented reality (VR/AR), (2022), S. 371-400
This chapter deals with the authoring of VR and AR applications. The focus here is on the use of authoring tools in the form of software development kits (SDKs) or game engines. First, the actual authoring process will be briefly discussed before selected authoring tools for VR and AR are reviewed. Subsequently, the authoring process and the use of the tools will be illustrated through typical case studies. The other chapters of this book deal with the fundamentals and methodologies of VR and AR. These are generally applicable over a longer period. In contrast to this, this chapter looks at some very specific authoring tools and the authoring process based on them, which can inevitably only represent a snapshot in time. Features, releases and availability of these tools can change at short notice, so that individual sections may no longer be up to date when this book is in press. To take this aspect into account, the case studies listed here are stored in an online repository, where they are regularly updated to reflect the latest versions of the authoring tools and runtime environments.
Fear and deprivation in Trump’s America: a regional analysis of voting behavior in the 2016 and 2020 U.S. presidential elections. - In: Personality science, ISSN 2700-0710, Bd. 3 (2022), e7447, S. 1-57
Since Trump was elected U.S. President in 2016, researchers have sought to explain his support, with some focusing on structural factors (e.g., economics) and others focusing on psychological factors (e.g., negative emotions). We integrate these perspectives in a regional analysis of 18+ structural variables capturing economic, demographic, and health factors as well as the aggregated neuroticism scores of 3+ million individuals. Results revealed that regions that voted for Trump in 2016 and 2020 had high levels of neuroticism and economic deprivation. Regions that voted for Trump also had high anti-Black implicit bias and low ethnic diversity, though Trump made gains in ethnically diverse regions in 2020. Trump’s voter base differed from the voter base of more traditional Republican candidates and Democrat Bernie Sanders. In sum, structural and psychological factors both explain Trump’s unique authoritarian appeal.
