Visual Realism

Adding virtual information that is indistinguishable from reality has been a long-awaited goal in Augmented Reality (AR). While already demonstrated in the 1960s, only recently have Optical See-Through Head-Mounted Displays (OST-HMDs) seen a reemergence, partially thanks to large investments from industry, and are now considered to be the ultimate hardware for augmenting our visual perception. In this article, we provide a thorough review of state-of-the-art OST-HMD-related techniques that are relevant to realize the aim of an AR interface almost indistinguishable from reality. In this work, we have an initial look at human perception to define requirements and goals for implementing such an interface. We follow up by identifying three key challenges for building an OST-HMD-based AR interface that is indistinguishable from reality: spatial realism, temporal realism, and visual realism. We discuss existing works that aim to overcome these challenges while also reflecting against the goal set by human perception. Finally, we give an outlook into promising research directions and expectations for the years to come.

An efficient and effective person re-identification (ReID) system relieves the users from painful and boring video watching and accelerates the process of video analysis. Recently, with the explosive demands of practical applications, a lot of research efforts have been dedicated to heterogeneous person re-identification (Hetero-ReID). In this paper, we provide a comprehensive review of state-of-the-art Hetero-ReID methods that address the challenge of inter-modality discrepancies. According to the application scenario, we classify the methods into four categories --- low-resolution, infrared, sketch, and text. We begin with an introduction of ReID, and make a comparison between Homogeneous ReID (Homo-ReID) and Hetero-ReID tasks. Then, we describe and compare existing datasets for performing evaluations, and survey the models that have been widely employed in Hetero-ReID. We also summarize and compare the representative approaches from two perspectives, i.e., the application scenario and the learning pipeline. We conclude by a discussion of some future research directions. Follow-up updates are available at https://github.com/lightChaserX/Awesome-Hetero-reID

This chapter introduces design and principles of head mounted displays (HMDs), as well as their state-of-the-art examples, for augmented reality (AR). Section 2 introduces a brief history of head mounted displays, human vision system, and application examples of see-through HMDs. Section 3 describes designs and principles of HMDs, such as typical configurations of optics, typical display elements, and major categories of HMDs. Section 4 gives typical characteristics of HMDs, such as resolution, field of view, and distortion. Section 5 describes human perceptual and health issues such as depth perception and safety. Finally, Section 6 gives conclusions with future challenges and prospects. For researchers, learners and HMD developers, this chapter is a good start point to learn basics, state of the art technologies, and future research directions of HMDs. For system developers and end-users, this chapter will give a good insight to HMDs to choose a suitable HMD for their purposes.

Crossing, or goal crossing, has proven useful in various selection scenarios, including pen, mouse, touch, and virtual reality (VR). However, crossing has not been exploited for freehand selection using augmented reality head-mounted displays (AR HMDs). Using the HoloLens, we explore freehand crossing for selection and compare it to the state-of-the-art “gaze and commit” (head gaze) method. We report on three studies investigating freehand crossing in multiple use cases. The first study shows that crossing outperforms head gaze in selection scenarios of varying target arrangements. The second explores crossing, head gaze, and hand pointing in radial menu and dynamic interface scenarios. The third explores crossing as a function carrier for a variety of basic interaction functions in a drawing application. This work builds on existing knowledge on the goal-crossing paradigm by demonstrating its potential as a useful interaction method in 3D AR HMD interfaces.

Is your love in vain? – dialectical dilemmas in Bob Dylan's recent love songs

The 1960S

In a recent interview, Bob Dylan said that he has learned never to ‘give one hundred per cent’ – a person, particularly a public artist, should always hold something in reserve. Somewhat taken aback, the interviewer pressed for a follow-up to this puzzling statement. Wasn't Dylan giving 100 per cent on those great albums of the 1960s. Highway 61 Revisited and Blonde on blonde? All right, Dylan finally admitted, maybe he was. The reporter dropped the question and went on to other subjects, leaving the readers, like Mr Jones, wondering just what is going on here. Most people who have followed Dylan's work throughout his career would agree that, in his work of the 1980s, he seems to be holding something back. There are flashes of brilliance, of the old verbal acuity, the ability to come up with the startlingly perfect phrase to fit his needs in a song. There have been truly great songs, like ‘Jokerman’, ‘Dark Eyes’ and ‘Brownsville Girl’. But there have also been embarrassingly awful songs, like ‘Never Gonna Be the Same Again’, lacklustre singing and woefully inconsistent production values on his records. We know what he is capable of – he knows what he is capable of – yet he doesn't give us his best. Why? In our view the answer, like most aspects of Bob Dylan, is not simple but may well involve a complex combination of factors all pertaining to the attempt to balance the dialectical forces pulling upon him from both the public and private areas of his life.

Legitimacy Crisis

This chapter presents the research questions and outline of the book, providing a brief review of the state of the art of legitimacy research in established democracies, and discusses the recurring theme of crisis throughout this literature since the 1960s. It includes a discussion of the conceptualization and measurement of legitimacy, seeking to relate legitimacy to political support, and reflecting on how to evaluate empirical indicators: what symptoms indicate crisis? This chapter further explains the structure of the three main parts of the book. Part I evaluates in a systematic fashion the empirical evidence for legitimacy decline in established democracies; Part II reappraises the validity of theories of legitimacy decline; and Part II investigates what (new) explanations can account for differences in legitimacy between established democracies. The chapter concludes with a short description of the chapters included in the volume.

The 1960S

This chapter shows how in Japan, the year 1945 represented a change of a very different kind. Japanese historians now repudiated the ultranationalist historiography of the 1930s and early 1940s, and turned in significant numbers towards Marxism, which rapidly achieved a kind of hegemony. They criticized the master narrative of the post-Meiji past, centered on the Tennō (emperor), and identified it with Fascism as a failed experiment in modernity. In the 1960s, however, this Marxist historiographical dominance was gradually supplanted by a pluralism of competing approaches. Modernization theory, social science methodologies, and ‘history from below’ coexisted, and historians, inspired by the Japanese economic miracle, tried to come to terms with the fact that Japan’s traditions, long perceived as an obstacle to modernization, actually seemed to foster it.
