Internet of Things (IoT): A vision, architectural elements, and future directions

This paper surveys the field of augmented reality AR, in which 3D virtual objects are integrated into a 3D real environment in real time. It describes the medical, manufacturing, visualization, path planning, entertainment, and military applications that have been explored. This paper describes the characteristics of augmented reality systems, including a detailed discussion of the tradeoffs between optical and video blending approaches. Registration and sensing errors are two of the biggest problems in building effective augmented reality systems, so this paper summarizes current efforts to overcome these problems. Future directions and areas requiring further research are discussed. This survey provides a starting point for anyone interested in researching or using augmented reality.

A survey of augmented reality

From the Publisher: 
A Question of Identity 
Life on the Screen is a fascinating and wide-ranging investigation of the impact of computers and networking on society, peoples' perceptions of themselves, and the individual's relationship to machines. Sherry Turkle, a Professor of the Sociology of Science at MIT and a licensed psychologist, uses Internet MUDs (multi-user domains, or in older gaming parlance multi-user dungeons) as a launching pad for explorations of software design, user interfaces, simulation, artificial intelligence, artificial life, agents, "bots," virtual reality, and "the on-line way of life." 
Turkle's discussion of postmodernism is particularly enlightening. She shows how postmodern concepts in art, architecture, and ethics are related to concrete topics much closer to home, for example AI research (Minsky's "Society of Mind") and even MUDs (exemplified by students with X-window terminals who are doing homework in one window and simultaneously playing out several different roles in the same MUD in other windows). Those of you who have (like me) been turned off by the shallow, pretentious, meaningless paintings and sculptures that litter our museums of modern art may have a different perspective after hearing what Turkle has to say. 
This is a psychoanalytical book, not a technical one. However, software developers and engineers will find it highly accessible because of the depth of the author's technical understanding and credibility. Unlike most other authors in this genre, Turkle does not constantly jar the technically-literate reader with blatant errors or bogus assertions about how things work. Although I personally don't have time or patience for MUDs,view most of AI as snake-oil, and abhor postmodern architecture, I thought the time spent reading this book was an extremely good investment.

物件導向軟體之架構(Object-Oriented Software Construction)探討

Repo-3D is a general-purpose, object-oriented library for developing distributed, interactive 3D graphics applications across a range of heterogeneous workstations. In this paper we discuss how Repo-3D simplifies exploratory programming of distributed 3D graphical applications, making it easy for programmers to rapidly evolve prototypes using a familiar multi-threaded, object-oriented programming paradigm. All data sharing of both graphical and non-graphical data is done via general-purpose distributed objects, presenting the illusion of a single distributed shared memory. Repo-3D is embedded in Repo, an interpreted, lexically-scoped, distributed programming language, allowing entire applications to be rapidly prototyped. We discuss Repo-3Di?½s design and how it supports exploratory distributed programming, present a number of illustrative examples, and discuss the pros and cons of this model for other programming tasks.

Exploratory programming of distributed 3d graphics applications

A seamless blending of the real and virtual worlds is key to increased immersion and improved user experiences for augmented reality (AR). Photorealistic and non-photorealistic rendering (NPR) are two ways to achieve this goal. Non-photorealistic rendering creates an abstract and stylized version of both the real and virtual world, making them indistinguishable. NPR hides unnecessary and overwhelming details of the world, and reveals and emphasizes important information of the scene. This could be particularly useful in some applications (e.g., AR/VR aided machine repair, or for virtual medical surgery) or for certain AR games with artistic stylization.
Achieving temporal coherence is a key challenge for all NPR algorithms. Rendered results are temporally coherent when each frame smoothly and seamlessly transitions to the next one without visual flickering or artifacts that distract the eye from perceived smoothness. For example, temporal coherence is maintained in brush-based NPR algorithms if the brush stroke located at a certain anchor point smoothly transitions to a corresponding anchor point from one frame to the next. NPR algorithms with coherence are interesting in both general computer graphics and AR/VR areas. Although NPR has attracted many researchers’ interest in the AR/VR community, very few of the existing algorithms can support temporal coherence. Rendering stylized AR without coherence processing causes the final results to be visually distracting. While various NPR algorithms with coherence support have been proposed in the general graphics community for video processing, many of these algorithms require thorough analysis of all frames of the input video and cannot be directly applied to real-time AR applications. We have investigated existing NPR algorithms with coherence in both general graphics and AR/VR areas. These algorithms are divided into two categories: Model Space and Image Space. We present several NPR algorithms with coherence for AR: a watercolor inspired NPR algorithm, a painterly rendering algorithm, and NPR algorithms in the model space that will support several styling effects.

Non-photorealistic rendering with coherence for augmented reality

In this position statement, we summarize a research seminar we are teaching this spring as a vehicle for discussing our common research interest in the design of augmented reality applications.

A multi-disciplinary course on augmented reality design

Mixed reality (MR), from location- and context- aware systems through immersive augmented reality applica- tions, has been studied in research labs for more than two decades. With the advent of the modern smartphone, and the rapid adoption of wireless broadband technologies, this re- search is moving out of the lab and into the real world. Beyond justprovidingaplatformforMRtoreachabroadrange of users, the capabilities and limitations of the smartphone provide a set of constraints on what kinds of applications can and cannot be delivered to consumers that have fundamentally changed how researchersthinkaboutMR.Weexaminepreviousdefinitionsof MR, and reimagine the term as a class of experiences occurring in an ecosystem consisting of the smartphone, the cloud, and the user. Using a selection of current MR applications as a lens, we identify three key areas of continuing evolution and suggest howthedevelopmentofanext-generationMRenvironmentcan help us channel the future growth of MR in research, industrial, and consumer communities.

Here We Are! Where Are We? Locating Mixed Reality in TheAgeoftheSmartphone This paper is about mixed reality and how the real-and-synthetic-scene hybrid is moving from the laboratory to the real world, technology to capability, space to place, and vision to perception.

In this paper, we treat VR as a new writing space in the long tradition of inscription. Constructing Virtual Reality (VR) narratives can then be understood as a process of inscribing text in space, and consuming them as a process of “reading” the space. Our research objective is to explore the meaning-making process afforded by spatial narratives—to test whether VR facilitates traditional ways of weaving complex, multiple narrative strands and provides new opportunities for leveraging space. We argue that, as opposed to the linear space of a printed book, a VR narrative space is similar to the physical space of a museum and can be analyzed on three distinct levels: (1) the architecture of the space itself, (2) the collection, and (3) the individual artifacts. To provide a deeper context for designing VR narratives, we designed and implemented a testbed called RealityMedia to explore digital remediations of traditional narrative devices and the spatial, immersive, and interactive affordances of VR. We conducted task-based user study using a VR headset and follow-up qualitative interviews with 20 participants. Our results highlight how the three semantic levels (space, collection, and artifacts) can work together to constitute meaningful narrative experiences in VR.
