By aggregating and analyzing data obtained from mobile devices, smartphones and wearable sensors, it is possible to realize crowd behavior such as congestion of public spaces such as stations, underground cities, shopping malls, and so on in real time. We are also conducting crowd sensing research using infrared equipments such as laser range sensors (range sensors) and so on.
As pervasive sensing progresses, Human centric Cyber Physical System (HCPS) will receive much attention where effects of human activities are taken into consideration for designing and developing CPS based societal systems. In our group, we focus on safe and secure urban life and study HCPS research.
New life innovation technology can be constructed by utilizing information terminals such as smartphones and small sensors. We are working on the development of ICT technology that contributes to the detection of heatstroke and the estimation of the activity situation of athletes.
We focus on efficient data exchange for acquiring local traffic information, distributed detection of dangerous vehicles on the road and/or highway and so on. We believe that these research contributes safety and comfortable car society.
In this research project, we consider emergency situations with limited availability of cellular networks and Internet connections in urban areas, and develop a methodology to autonomously organize survived communicating nodes to realize a large-scale, tempo-spatial information gathering.
It is expected to make the best use of sensing devices for disaster mitigation. Mega-order vehicular traffic data were collected through probe-car systems and passable roads were shown on Google Maps day by day after 2011 Tohoku earthquake. Recent IT technologies have large potential for disaster mitigation.
We have developed a network simulator "MobiREAL" for realistic evaluation of MANETs. It enables us to specify realistic behavior of mobile nodes, which may change their behavior and location depending on their surrounding information.
We consider situations where many persons are simultaneously injured in disaster, and propose an advanced electronic triage system. It presents dynamic change of injured persons' location and physical condition on monitors in real time.
