Tiled Display Environment to Realize GIS Based Disaster Information System

Understanding of damage information in disaster situation is the most important role for emergency response headquarters in order to provide relief action. Although responder in actual large-scale disaster situation could not deal damage situation easily that is ascribable to difficulty for understanding of spatiotemporally damage information. This paper proposes a GIS based disaster situation displaying and sharing approach system for represent disaster damage information at emergency response headquarters in large-scale disaster, to provide association between geolocation and multimedia content which is taken into disaster affected area. Our approach presents images of damage situation upon digital map on a high resolution single and large sized display, allows helping of damage by detail of damage situation in specific area not only showing it. We designed system architecture, use case of system and human computer interaction under operation for damage situation collection on large scale tiled display system. This system can be connected multiple counter disaster sites each other with disaster controlling network in an effort to share digital pictures and/or videos of disaster situation. We also discuss task oriented intuitive input method for our disaster information GIS. We will use some tablet devices in each site to make considerations interaction of system with multiple users.

A GIS Based Disaster Status Sharing and Representation System Using Ultra Definition Display Environment

In case of large scale disaster has been broken out, a large number of disaster damage information are reported from over wide area to disaster countermeasure headquarters. Modern disaster management GISs have limitation of number of statuses at the same time, it suggests restriction of efficiency in case of catastrophic disaster. On the other hand, sharing of damage situation is performed asynchronously in actual disaster management operation, appropriate sharing of status might be a kind of difficult task in disaster management. This paper describes a proposal design of disaster information representation GIS based system on large scale and ultra definition display system. We designed proposal system intents to represent detailed disaster status and wide-areas one with compatibility as well as to provide multiple users disaster information, by using Tiled Display Wall environment. Proposal system provides tablet based intuitive interaction device for user who handles geolocation information, not just conventional interaction method. We consider this system is operated with dedicated network which provides persistent connectivity even though normal time broadband networking is disabled or exceedingly limited.

To this goal the emergence of adequate information and communication technologies with respect to high performance computing-networking-visualisation and their mutual awareness is required. The developed technology and algorithms will be applied to a real peta-scale data intensive scientific problem with social importance, i.e. human upper airway flow modelling.

Study on Tele-immersive Communication with Multi-video Streaming on Tiled Display Wall

In tele-communication via WAN, the existence of participant by video streaming in real scene is important. In addition, we consider that non-verbal communication play an important role. In order to realize realistic communication between remote places, the display of video image in remote site with the large-scale screen is effective. However, the video image on wide-area display with a projector and large screen is low-resolution, and sufficient presence is not obtained. In past, we have constructed tele-immersive environment with tiled display wall to realize realistic remote communication with video streaming. However, the video image by single small camera is difficult to display with realistic high-resolution on tiled display wall, because there is a limit in the display resolution of video image captured by a small camera. In this paper, we have proposed the technique to realize high-speed display of realistic high-resolution video image on tiled display wall by transmitting each video image data which captured by multiple cameras and compositing as a high-resolution video image. From the experimental result, the video image could display more high-quality than expanded video image by single small camera. In addition, we have measured the network throughput performance for each transmission video in the system, and steady throughput performance has been gained in the case of each video image.

Experimental Evaluation on Transmission and Display of Ultra-Resolution Video on Tiled Display Wall in JGN-X Testbed

In order to realize high-realistic sensation telecommunication over Wide-Area Network, we consider that non-verbal communication play an important role, and displaying the existence of participant by ultra-quality video in real-time on large-scale screen system between each remote site is effective. However, displaying a video with realistic high-resolution in real-time is difficult, because there is a limit in the display resolution of video image captured by a single camera. In existing researches, we have constructed the telecommunication environment to display ultra-resolution video streaming by multi-transmitting each video which captured by multiple cameras with the tiled display wall which is a technology to display various high-quality visualization contents by configuring the large-scale display with two or more LCD panels. However, the adjustment of each camera position is necessary to display an ultra-resolution video by combination of boundary area between each captured video, we have studied on the effect of position setting of multiple cameras. Based on these studies, we have conducted an experimental evaluation on ultra-resolution video transmission and display on tiled display wall between remote sites in JGN-X testbed in this paper.

Tele-immersive environment with tiled display wall for intuitive remote collaborative work

In remote collaborative work via WAN, sharing and recognizing various high-quality visual contents such as photography, visualization image, and real video streaming is extremely important. Supporting a high-quality display of these contents on a large-scale display system is necessary to support intellectual remote collaborative work. However, these contents are currently magnified in low resolution on a general projector used as large-sized display equipment, and these equipments are difficult to display the contents with sufficient quality. In this paper, we have focused on the tiled display wall technology which configure a wide-area screen with two or more LCD and tried to display realistic high-resolution visual contents to solve these issues. We have constructed a tele-immersive environment with a tiled display wall, and have studied the availability for intuitive remote collaborative work by implementing various collaborative applications for the effective display of high-resolution contents as well as developing interaction techniques for enormous visual contents in this environment. As a result, we have showed that the practical use of a tiled display wall is useful in the construction of intellectual remote collaborative environment.

In past research, we have constructed tele-immersive environment with tiled display wall to realize high-realistic tele-communication. However, the video image captured by a single small camera is difficult to display as video streaming with realistic high-resolution on tiled display wall, because there is a limit in the display resolution of video image captured by a single camera. In response to these issues, we have constructed the tele-communication environment to display a ultra-resolution video image on tiled display wall by multi-transmitting each video which captured by four cameras with tiled display wall.
