A collaborative virtual reality environment (CRVE) can be used in molecular biology because it can provide users with virtual experiences of three dimensional molecular models in cyberspaces. Therefore, we developed a remote collaboration system for molecular docking and crystallography using virtual reality techniques. The collaborative works of molecular docking were successfully exercised. We also conducted visualization and manipulation of three dimensional biomolecular models and supported discussions of remote participants for crystallography using the collaborative system.

Although various discriminant analysis approaches have been used in Content-Based Image Retrieval (CBIR) application, there have been relatively few concerns with kernel-based methods. Furthermore, these CBIR applications still applied discriminant analysis to face images as face recognition did. In this paper we concerns images with general semantic concepts. We use our presented symmetrical invariant LBP (SILBP) texture descriptor to extract image visual features. We then explored effectiveness of Principal Component Analysis (PCA), Fisher linear discriminant analysis (LDA), and Kernel LDA algorithms in providing optimal discrimination features. Following it, we present an LDA based framework to carry out kernel discrimiant analysis in our application. By taking advantage of the efficiency in nonlinear condition of kernel-based methods and the simplicity of LDA, the proposed approach can improve the retrieval precision of CBIR. The experimental results validate the effectiveness of the proposed approach.

Smart phones are becoming visual computing powerhouses. Using sensors such as camera, GPS, and others, the device can provide a new user interface to the real world, augmenting user's view of the world with additional information and controls. Combining computation with image capture allows new kind of photography that can be more expressive than is possible to obtain with a traditional camera. New APIs allow harnessing more computation power of a smart phone to visual processing than what one can obtain from just a CPU.

In this paper, we propose a concept of Context Aware Mobile AR (CAMAR) mashup as an enriched form of participatory user interaction in U-VR environment. 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.

In this paper we present ideas that can help to close the gap between virtual reality and embedded interaction, which are usually assumed to be the two extremes of a dimension that describes mixed reality interaction. We present our preliminary ideas on surface interaction with stereoscopic data as well as our work on mobile camera-projector units. While the first line of research tries to increase the degree of the interaction experience in virtual worlds, the second uses the physical properties of the real world to enhance the augmented reality experience. The first idea uses the physical world to constraint the interaction in the virtual world. The second idea embeds virtual information into the physical world by respecting its physical properties.

In this paper, we propose a novel tag framework for sharing information in dual-reality space, which is based on context-aware mobile augmented reality (CAMAR). When a user selects a target object to be tagged onto dual-reality, the proposed framework and procedures create CAMAR Tag with a user’s mobile device to be registered in virtual space. CAMAR Tag is able to play a role as a reference point, a sharing point and a key of contextual searching. We present a concept behind CAMAR Tag and how it can be generated, implemented and deployed in dual-reality.

With the rapid spreading of ubiComp and mobile augmented reality, the interaction of mobile users in U-VR environments has been evolving. However, current interaction is limited in individuals’ experience with given contents and services. In this paper, we propose CAMAR 2.0 as a future direction of CAMAR aiming at improving perception and interaction of users in U-VR environments. We thus introduce three principles for future interaction and experience in U-VR environments. We also discuss technical challenges and promising scenarios for realizing the vision of CAMAR 2.0 in U-VR environments.

Wikis are very useful for collaborative learning because of their sharing and flexible nature. Many learning activities can use Wiki to facilitate the processes, such as online glossaries, project reports, and dictionaries. Some EFL (English as a Foreign Language) instructors have paid attention to the popularity of Wiki. Although Wikis are very simple and intuitive for users with information literacy, Wikis need computing environment for each learners to edit Web pages. Generally, an instructor can only conduct a Wiki-based learning activity in a computer classroom. Although mobile learning devices (such as PDAs) for every learner can provide ubiquitous computing environment for a Wiki-based learning activity, this paper suggests another inexpensive way by integrating digital pen with Wiki. Consequently, a learner can annotate an EFL reading with his/her mother tongue by digital pen. After everyone finishes reading, all annotations can be collected into a Wiki system for instruction. Thus, an augmenting Wiki structure is constructed. Finally, learners’ satisfactions about annotating in the prototype system are reported in this paper.

Modern society generates and shares great amount of information with rapid development of information and communication infrastructure. The development, however, makes people too busy to communicate enough time with families and accelerates separation of families in a sense of physical and social location. In this paper, we describe two concepts of stories for messages of the communication. The stories are generated from dynamic context information and story template. Then we describe an implementation of a system that enhances inter-communication among intimate group members such as families and friends by providing opportunities of story exchanges for keeping in touch with them. The system helps for improving individual’s Quality of Life (QoL) and social health.
