The triage tag is used in Mass Casualty Incident (MCI) to check the priority of patients treatments and conditions. However, it is difficult to grasp a change in the patient's information since it is a paper tag. In this paper, we propose a system using the electronic triage tag (eTriage) that facilitates emergency medical technicians to grasp patients locations and conditions through visualization...
We describe an augmented reality prototype for exploring a 3D urban environment on mobile devices. Our system utilizes the location and orientation sensors on the mobile platform as well as computer vision techniques to register the live view of the device with the 3D urban data. In particular, the system recognizes the buildings in the live video, tracks the camera pose, and augments the video with...
We present the use of commodity depth based cameras to control viewpoint from passive unencumbered head tracking. This allowed participants to maintain correct perspective while playing an immersive computer ball game, without the need to wear devices, wires or markers. While viewpoint update is more generally useful than stereoscopy it has traditionally used tracking equipment of expense and complexity...
Low delay interactive 3D multi-angle live streaming system is proposed to provide users with high sensation of both depth impression and realistic feeling, by viewing 3D video and low delay interaction of camera angle change. The proposed system consists of real-time multi-view encoding part and low delay server client streaming part. The server has the live stream buffer management for extraction...
The display of complex 3D scenes in real-time on mobile devices is difficult due to the insufficient data throughput and a relatively weak graphics performance. Hence, we propose a client-server system, where the processing of the complex scene is performed on a server and the resulting data is streamed to the mobile device. In order to cope with low transmission bit rates, the server sends new data...
The availability of low-cost virtual reality (VR) systems coupled with a growing population of researchers accustomed to newer interface styles makes this a ripe time to help domain science researchers cross the bridge to utilizing immersive interfaces. The logical next step is for scientists, engineers, doctors, etc. to incorporate immersive visualization into their exploration and analysis workflows...
Mixed reality techniques are boosting for aviation progress. In this paper, we present MRStudio, a mixed reality display system for aircraft cockpit. The system architecture is given, with special attention paid upon such technical issues as three-dimensional map construction for aircraft cockpit, computer vision based 6-DOF head tracking, virtual aircraft cockpit panel construction and registration,...
In this study, we construct a stereo camera sensor network system designed for use with a breeding database. We collect stereo images using the system, and we propose an evaluation method to indicate leaf growth. We are able to obtain an evaluation value from the three-dimensional (3D) shapes of tomatoes, and thus we can evaluate the tomato plant canopy using our system. Our proposed system can analyze...
This paper presents an efficient video-on-demand (VOD) scheme for free viewpoint television (FTV), and proposes a data format and its data generation method to provide a walkthrough experience. We employ a hybrid rendering approach to describe a 3D scene using 3D model data for objects and textures. However, conventional hybrid rendering methods such as multi-texturing include excessive redundancy...
This contribution describes a distributed multi-camera capture and processing system for real-time media production applications. Its main design purpose is to allow prototyping of distributed processing algorithms for free-viewpoint applications, but the concept can be adapted to other (multicamera) applications. The system integrates broadcast components into a distributed IT-based processing system...
We present a framework for collaborative cyberarchaeology aimed at remote real-time interaction with 3D archaeological models through a shared virtual environment. The project combines research in 3D computer vision, collaborative virtual reality and archaeology. At each geographical location, a set of stereo cameras captures 3D video of the user in real time to create his/her avatar. The 3D data...
Future normally-unmanned oil platforms offer potentially significantly lower commissioning and operation costs than their current manned counterparts. The ability to initiate and perform remote inspection and maintenance (I&M) operations is crucial for maintaining such platforms. This paper presents a system solution, including key components such as a 3D robot vision system, a robot tool and...
Virtual Reality is becoming more than a part of our everyday life, helping us to identify quickly the elements of the environment or to better entertain us. The purpose of this paper is to present an application framework that we are developing, in order to help others implement their own applications. In the first section the focus is set on the Augmented Reality basic concepts and the necessity...
In this paper, we propose 3D space which is based on concept of real and digital spaces symbiosis. Recently, collaborative work environments which are using Augmented Reality have been expected to realize effective collaborative works. However, these environments have some limitations. One of limitations is restricted availability of devices, and another limitation is low usability. Because of these...
We present a prototype collaborative application for archaeology that allows archeologists from remote locations to interact in real time with 3D archeological models through a shared virtual environment using teleimmersive technology. At each location, a set of stereo cameras captures 3D video of the user in real time to create his/her avatar. The 3D data is sent over the network to the remote location...
The prototype of time-shifted system on multi-view video is proposed for the first time in this paper. Synchronous locating of multi-view video streams is one of the key issues in supporting time-shifted function. In time-shifted system, video streams are forever lasting, the relative time, as the traditional locating index, now is meaningless to clients, as they would never know when the real moment...
In this paper we present a Mixed Reality (MR) teleconferencing application based on Second Life (SL) and the OpenSim virtual world. Augmented Reality (AR) techniques are used for displaying virtual avatars of remote meeting participants in real physical spaces, while Augmented Virtuality (AV), in form of video based gesture detection, enables capturing of human expressions to control avatars and to...
For several decades, many researches had done to improve user interface. Multi-touch technology is one of the emerging technologies and some products are shown and getting users' attention in the market. In this paper, we introduce two types of 3-dimensional multi-point input systems of using two-hands in an open space. They were implemented in a form of a wearable computing system for providing users...
Research project FLOREON+ deals with disaster management support. Philosophy of the project is based on its modularity which enables integration on seemingly unrelated problem domains. The research is primary focused on modeling and simulation of flood risk, traffic, and water and air pollution. Domain areas can be extended in the future. This paper is aimed at description of visualization module...
