In this paper, a framework binding 3 PoIs with distinctive features into a successive, cohesive, and immersive narrative is introduced. It applies and improves upon the Memorable Experience Design(MED) Framework and the Interest Curve proposed by Bulencea and Egger (2015) to guide tourists through Daereungwon, while game challenges and rewards in the form of augmented objects and interactions provide them with information on the PoIs and Daereungwon as a whole.

To experience it, we define two major enabling technologies: 1 Context-of-Interest CoI based Trans-Space registration and selective augmentation and 2 augmented object interaction for realistic collaboration. Through these technologies, a user wearing augmented reality AR glasses can naturally experience remote collaboration with spatial co-presence while moving in space. We implemented a prototype of the Trans-Space for a preliminary test experiencing spatial co-presence in an indoor environment. With an assumption that a common physical CoI is in each space, a distant mirror space can be conveniently linked with real user's mirror space and they are merged together as a Trans-Space. Through the proposed convergence system, a human's co-presence experience can be enlarged by selectively context sharing and effectively spatial interaction between remote mirror spaces. We expect this is applicable to AR-based time/space transcended smart applications, such as the next generation of experimental education, training, medical surgery, and entertainment.

In this paper, we propose a smart recommendation for highly efficient and balanced itineraries based on multiple user-generated GPS trajectories. Users only need to provide a minimal query composed of a start point, an end point and travel duration to receive an itinerary recommendation. To differentiate good itinerary candidates from less fulfilling ones, we describe how we model and define itinerary in terms of several characteristics mined from user-generated GPS trajectories. Further, we evaluated the efficiency of our method based on 17,745 user-generated GPS trajectories contributed by 125 users in Beijing, China. Also we performed a user study where current residents of Beijing used our system to review and give ratings to itineraries generated by our algorithm and baseline algorithms for comparison.

Researchers in mobile AR technology have emphasized the technical challenges involved in the limitations imposed from mobility. They did not consider context-aware service with user-related information annotation, even if in ubiquitous computing environment, various contexts of both a user and an environment can be utilized easily as well as effectively. Moreover, it is difficult to have access to pervasive but invisible computing resources. At the same time, the more smart appliances become evolved with more features, the harder their user interfaces tend to become to use. Thus, in this paper, we propose Context-aware Mobile Augmented Reality (CaMAR) system. It lets users interact with their smart objects through personalized control interfaces on their mobile AR devices. Also, it supports enabling contents to be not only personalized but also shared selectively and interactively among user communities.

In this paper, we introduce a concept of in-situ AR mashup content (AMC) as a new type of end-user created content for AR applications and as a concentrated digital trace that reveals Social and Community Intelligence (SCI). Especially, we present an AMC-based application for an art gallery that focuses on a specific representation format for AMC and the underlying architecture that enables such user participation. The proposed in-situ AR mashup elevates, otherwise passive users to active contributors of the content ecosystem by adding informational and experiential content. As a result of such content mashup activities, currently limited and frozen AR content ecosystem can be enriched and revamped. At the same time, the user-generated AMC implicitly leaves rich and multi-dimensionally structured digital traces that can be collectively used to build SCI.

Ubiquitous Virtual Reality (U-VR) has been researched in order to apply the concept of virtual reality and its technology into ubiquitous computing. In this paper, we analyze past research on ubiquitous virtual reality and find future research direction.

We define CAMAR mashup and discuss how its characteristics are different and distinguishable from previous mashup activities in various additional aspects such as context-awareness, mobility and presentation. To elaborate the proposed concept, an exemplar scenario is presented and foreseeable technical challenges are discussed. 1 1.

Unlike conventional interface such as keyboard or joystick, the proposed system provides more natural and comfortable interface by exploiting rnuitimodal interfaces such as 3D vision and speech recognition. In addition, the proposed 3D vision-based interface allows relatively free-movement in 3D space, ...

T... more In this paper, we present the Responsive Multimedia System, an interactive edutainment system.. The system consists of an AR-based tabletop tangible user interface (ARTable) and a virtual environment manager (VEManager) integrated by enhanced Personalized User Interface Framework. In this system, a user interface and virtual environments are integrated seamlessly by sharing user-centric context. To share user-centric context efficiently, our system optimizes the number of network connection between objects in real and virtual environments. The synchronization problem between ARTable and a virtual environment is solved by calculating coordinates with additional information such as collision with terrain and physics law in a virtual environment as well as user-centric context. Moreover, it reorganizes responses of an object according to a user-centric context and condition-action rules. To demonstrate the effectiveness of the proposed system we developed an application on the subject 'Dream of Mee-luck'. According to the experimental results, we found that the proposed system could be a promising technology that enables users to experience an interactive story. In the future, the proposed system can play an important role in developing interactive applications for edutainment.

The ISUVR series continues to provide an interdisciplinary forum for leading researchers and graduate students, especially in the areas of ubiquitous computing, virtual reality, and augmented reality. The 2010 symposium's theme, "Toward a Digital Ecosystem," emphasized the roles of end users in actively creating and maintaining content in a managed systematic way, referred to as the digital ecosystem. The four-day conference consisted of tutorials, invited talks, paper and poster presentations, a panel talk, and a social event. Approximately 60 researchers and students from Europe, Asia, and the US attended.

We propose a software architecture to support a sustainable service environment based on a content ecosystem in a smart gallery. To continuously enrich contents, the proposed architecture presents spatial contents over physical objects, allows users to generate new contents by extending the contents and enables them to selectively share contents in real-time through a server. The proposed architecture also enables the generated and shared contents to behave intelligently, based on a layered response ...

We develop a vision-based tangible AR interface to support intuitive interaction with billiARds system. In order to enhance user's experience, we go a step further by adding forcefeedback to the tangible interface. Our primary contribution is incorporating force-feedback into AR without restraining mobility of the user. To achieve this, we design a wearable device for force- ...

However, most ways of describing context are specific to purpose of each service or give undue value to particular information, eg location. In this paper, we propose unified context, which describes usercentric situation without dependence on purpose of any service, in terms of 5W1H (Who, What, Where, When, How, and Why). The proposed ...
