    Over the past 20 years, a lot of effort has gone into making the vision of ubiquitous computing a reality. A major focus of this effort has been on the understanding of human activity as input to enable the design and implementation of context-aware applications. Context-awareness is a vital enabling technology for ubiquitous virtual reality applications. However, it is only recently that we have ... View full abstract»

    Today's mobile devices have inherited many of the characteristics of desktop computing -- including the assumptions that the user's full attention and dexterity can be focused on the interface. Unfortunately, on-the-go users are impaired by their mobility and often find desktop-style Windows Icon Menu and Pointer (WIMP) interfaces difficult, if not impossible, to use while performing their primary...

    Rapid prototyping allows for evaluation of design product in a short period of time. Designers or CEOs may perceive the size and appearance of the product by touching the automatically constructed physical objects produced through rapid prototyping. However, it is usually impossible to change its color, texture, and user interface. In this paper, we introduce 'Augmented Reality based Re-formable M... View full abstract»

    In this paper, we propose a tensor-based active appearance model (AAM) which improves the fitting performance of conventional AAM. Tensor-based AAM generates the specific AAM basis vectors by indexing the model tensor in terms of the estimated input image variations. Experimental results show that the proposed tensor-based AAM reduces the average fitting error than the conventional AAM significant... View full abstract»

    Diminished reality is a technique that provides visual convenience by virtually hiding an object. Despite that the promising advances of projection-based vision techniques provided good solutions for vision applications, there has no report of the development of diminished reality systems using projection-based vision techniques. As a first attempt, this paper proposes a projection-based diminishe... View full abstract»

    As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrast... View full abstract»

    In 3D computer graphics, it has been an important issue to describe a virtual object realistically and show it in a physically correct manner. Unlike the virtual reality(VR), the augmented reality (AR) is an environment containing virtual and real objects simultaneously. However, the difference in motion between the virtual and real objects is obvious, which makes it hard for AR to be realistic an... View full abstract»

    3D virtual objects can be augmented in the streaming data through a webcam for various purposes using a marker and AR techniques. But the augmented results without shadows it can be shown unnaturally because the illumination of the real scene does not be considered. To minimize the unnaturalness between the background and virtual object, the illumination of the background is uniformly applied to t... View full abstract»

    In this paper, we propose Simple Frame Marker (SFM) which has a rectangular frame and encompasses a planar natural view such as characters, logos and images. In order to support recognition of characters as well as an image, Simple Frame Marker is constructed by square-type and rectangle-type markers. Therefore Simple Frame Marker first distinguishes its content by the marker type and applies a pr... View full abstract»

    In this paper, we study how to exploit the context-awareness in augmented reality (AR) applications to take advantage of the context in both the high-level and low-level processing. We propose an AR system architecture that works with a context-awareness framework. In the system, both the preliminary and the final context is provided to the process that needs the context. We provide two scenarios ... View full abstract»
