To support the evacuation process of crowds from emergency situations, we have developed a wearable device, LifeBelt, for vibro tactile guidance of individuals in panic towards exits. Since visual and auditory perception is overwhelmed in situations of panic, exit sign and loudspeaker based evacuation often appears ineffective. LifeBelt as a coordinated(More)
To increase crowd evacuation efficiency in emergency situations, the authors developed a wearable computer, LifeBelt, to guide individuals from emergency situations to escape. The LifeBelt collects position and orientation information about individuals from embedded sensors, shares this information with a background emergency coordination system, receives(More)
Due to catastrophic disasters induced by forces of nature like flooding or tsunamis, terrorism or nuclear power plant accidents, understanding the dynamics of urban evacuation systems has elicited massive interest over the past years. While discrete event simulations of evacuation models become prohibitively complex dealing with the time, space and(More)
A considerable increase in road traffic has provoked a total change in the operating paradigms of vehicles, shifting vehicle handling from “just steering” towards a complex adaptation task. With the emergence of wireless communication technology, vehicle operation can now incorporate for the first time ever beside the local driver-vehicle(More)
While modelling (and simulating) a socio-technical system, the primary focus has been on the technological side almost ignoring the social dimension of it. However, with recent advancements in Ambient Intelligence (AmI) and emotions sensing technologies, it is now possible to fill this gap. To this end, we have integrated cognitive decision making model(More)
To individuals evacuating, many multi-exit environments do not allow visibility of all the exits due to line-of-sight constraint. In addition, the environment can be dark or smoky, not allowing visibility to even a single exit. In such a situation, given that each individual in the crowd is accompanied with a helping device globally connected with a central(More)
