    Until recently, most content on the Internet has not been explicitly tied to specific people, places or things. However, content is increasingly being geo-coded and semantically labeled, making explicit connections between the physical world around us and the virtual world in cyberspace. Most augmented reality systems simulate a portion of the physical world, for the purposes of rendering a hybrid... View full abstract»

    In this paper, we propose a concept of u-Content ecosystem in ubiquitous VR environments. We present a definition and features of u-Content ecosystem, and describe its application scenario to interacting with users in ubiquitous VR environments. We also explain the u-Content life-cycle that includes resources, contents production, growth, evolution, reproduction, and destruction. View full abstract»

    This paper presents a practical method to estimate the positions of light sources in real environment, using a mirror sphere placed on a known natural marker. For the stable results of static lighting, we take the multiple images around a sphere and estimate the principal light directions of the vector clusters for each light source in running-time. We also estimate the moving illuminant for chang... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (346 KB) | HTML iconHTML

    Soft tissue simulation is very important in medical simulation and learning procedures. But such simulations require intensive computation. With the force feedback devices, the computation required should be much faster as touch sensation is approximately 20 times faster than that of visual. In this paper an efficient Vertex based algorithm for visual deformation is presented. Visual deformation o... View full abstract»

    Due to the incomparable ability to increase realism in synthesizing the motion of virtual objects, physics simulation is increasingly adopted in augmented reality (AR) applications. In this paper, we show with experiments that, if physics simulation is naively employed in AR applications, visual artifacts diminishing the realism of a scene may occur when real and virtual objects collide. This is d... View full abstract»

    Table-top is collaborative work space providing large touch screen which is capable of multi-touch interface. To make an extended collaborative work space without restriction of time and place, one possible way is adoptingmobile devices. In this paper, we propose a way to monitor and control the table-top using mobile devices. To monitor the large-screen table-top with a mobile device, it is neces... View full abstract»

    Request permission for commercial reuse | Click to expandAbstract | PDF file iconPDF (234 KB) | HTML iconHTML

    This paper focuses on time-efficient data congregation protocols on a Dynamic Cluster-based Wireless Sensor Network (CBWSN). The CBWSN is self-configurable and re-configurable, thus capable of performing two dynamic operations: node-move-in and node-move-out. In this paper, we propose two efficient congregation techniques for Dynamic CBWSN. In order to facilitate the efficient congregation protoco... View full abstract»

    We propose a mARGraphy, which visualizes information based on augmented reality (AR) technology. It provides the intuitive and interactive way to make users to understand dynamic 3D information in situ with highly relevant to the target. To show the effectiveness of our work, we introduce a traditional map viewer application. It recognizes region of a traditional map with object recognition and tr... View full abstract»

    In this paper, we propose a planar target tracking method that exploits a barcode containing information about a target. Our method combines both barcode detection and natural feature tracking methods to track a planar object efficiently on mobile devices. A planar target is detected by recognizing the barcode located near the target, and the target's keypoints are tracked in video sequences. We e... View full abstract»

    In this paper, we suggest a mobile phone-based indirect 3D object manipulation method that uses sensor information in an augmented reality environment. Specifically, we propose 1) a method that exploits a 2D touch screen, a 3DOF accelerometer, and compass sensors information to manipulate 3D objects in 3D space, 2) design transfer functions to map the control space of mobile phones to an augmented...

    Three different types of cartoon-like stylization methods are introduced. First, we introduce the rubber-like exaggeration method that allows a virtual character to stretch and bend its limbs flexibly by subdividing the joint hierarchy. Second, a slow-in and slow-out filter is introduced, which is based on the time-shift filter and is useful to give a slow-in and slow-out effect to a character. Fi... View full abstract»

    This paper introduces an education system for typical assembly procedures that provides various haptic sensory information including active and passive haptic feedbacks. Using the system, we implemented four kinds of training methods and experimentally evaluated their performances in terms of short-term and long-term memory over the task. In results, active haptic guidance showed beneficial effect... View full abstract»
