Our Dream

On-Site Visualization Consortium has been developing technology of light-emitting sensors that change colors instantaneously upon detection of any deformation or inclination found in infrastructures. Our wish is to contribute to enhancement of safe, secured, and enjoyable environment of our daily life and at workplaces by establishing systems for real-time data processing and display called “On-Site Visualization” through collaborative efforts by industry, government, and academia.

Motivation

We are facing a wide variety of threats to our physical safety that are natural, force majeure, and/or inadvertent. People get injured or taken their precious lives in landslide disasters due to torrential rain or typhoons, accidents at construction sites, accidents of large-scale amusement rides like roller coasters due to inadequate maintenance, accidents due to insufficient strength of buildings and structures, and collapse of houses due to force majeure such as snow load and flood In order for us to detect factors of such risks promptly and notify them to the population of the area to be affected, we need to install various sensors, to process signals of risks from the sensors immediately, and to communicate the resultant messages in easy-to-understand forms. However, conventionally available sensors tend to be very costly, and it is impossible to monitor all risk factors at every location. New and unconventional methodology is needed to realize safe living environment while securing safety of ourselves at low cost.

Methodology

To achieve this objective, we have been developing variety of new sensors. They can be installed at any location, detect changes of any data (e.g. deformation, strain, pressure, temperature, and humidity), display the changes and their magnitude with LEDs in altering colors. Workers on the site as well as people in the neighborhood can, in this way, visually confirm the changes in real time. This enables construction of totally new disaster-prevention/safety-monitoring systems that are unconventional in many ways. Conventionally, what sensors detect are checked on PCs or through other medium at remote locations.

On Site Data Processing and Visualization

This methodology has a potential of realizing a totally new information acquiring/disclosure system which we can call “On-Site Visualization” system. The methodology of detecting changes around us and visualizing the changes in altering colors of light on site can be applied not only to disaster prevention measures but also to regular safety monitoring of any structure that relates to our lives (civil structures, buildings, heavy machinery, large-scale amusement vehicles etc.). Furthermore, the light colors can be altered in response to movement of arbitrary structures; so that this methodology can make school education on simple mechanics more enjoyable and may also lead to creation of a new entertainment tool.

Potential

Thus, the new concept underlying this new monitoring method using light-emitting sensors can be applied to every safety monitoring program ranging from prevention of natural disasters to promotion of safe/secured living environment. A totally new and unconventional system can be structured using in-situ real-time display of monitored information with altering light colors. Thus, there is a large potential for very extensive application of this concept in Japan and in other countries by structuring a series of system models for monitoring variety of engineering quantities at various scales.

New Challenge

There has been very little disclosure of information to the general public concerning various structures that form our social infrastructure. What to do with these structures have been totally left to administrators and experts. By introducing the “light-emitting sensors” to these structures, we will start living in the environment of “ultimate 24-hour information disclosure,” a whole new living environment that no country in the world has experienced yet. In order for us to establish such a new concept in our society and to create safe/secured environment in reasonable manner, unceasing cooperative efforts and information exchange between experts and the general public are essential.

New Responsibility

This new concept requires designers and administrators of structures to determine where to install the light-emitting sensors and how to design displacement levels and color-altering ranges for securing safety of users of the structures (e.g. neighborhood residents, audience, and general passerby). The neighborhood residents are required to learn about displacements, color changes, and risk levels and to participate in periodical evacuation drills, so that they can protect themselves by looking at light-emission of sensors, and as well, they can promptly report risks to the administrators. They are going to be required to “judge safety in their imminent environment” that used to be left to administrators and experts. The “light-emitting sensors” will enable people to make such judgment.

Human networking

OSV Consortium was established on January 9th, 2010 for the purposes of arousing needs for OSV through participation by industry, government, academia, and individual citizens and creating a venue for free and active discussions, implementations, information exchanges, and human interactions for national and international promotion of the innovative concept of “On-Site Visualization” in the field of safety/security of living/working environment. We will continue our efforts for these purposes and expand the human network to promote development and application of more effective low-cost sensors to win safety for all in the new way.
