- Serious games for the Elicitation of way-finding behaviours in emergency situationsPublication . Almeida, João Emílio; Jacob, João Tiago Pinheiro Neto; Faria, Brígida Mónica; Rossetti, Rosaldo J. F.; Coelho, António LecaUnderstanding human behaviour in emergency evacuation from buildings is of utmost importance for fire safety designers, architects and engineers as they elaborate on strategies to improve the emergency paths to exits. This paper describes an experiment designed to elicit human behaviour when facing the urgent need of exiting a room of an unknown building. This test is part of a methodological approach that aims at the creation of a framework coined SPEED (Simulation of Pedestrians and Elicitation of their Emergent Dynamics). A population sample of 22 subjects was used to test such a methodological approach, which consists in having the subjects answering a questionnaire and later on, in playing a Serious Game. The game environment presents the same scenarios shown in the questionnaire using more elaborated 3D rendering to provide players with a sense of realism. The game was developed under the Unity3D game engine and based on the Serious Games concept. Preliminary results are promising, showing that the challenge made players think about the various situations that might happen when facing an emergency. They are also implied to reason on their stream of decisions, such as which direction to take considering the environment and some adverse situations, such as smoke, fire and people running on the opposite direction of the emergency signalling.
- Towards a methodology for human behaviour elicitation: preliminary resultsPublication . Almeida, João Emílio; Rossetti, Rosaldo J. F.; Faria, Brigida Monica; Jacob, João Tiago; Coelho, António LeçaHuman behaviour knowledge is an important requirement for implementing realistic evacuation models. Although much work has been done in this field of research there are no universally accepted quantitative methods. In this paper we present a novel methodology for human behaviour elicitation that was coined SPEED (Simulation of Pedestrian and Elicitation of their Emergent Dynamics). An experimental setup to test the concept was envisaged and validated by a group of experts using the Delphi method. A test bed was designed using the Serious Games concept and 22 subjects were selected for a pilot test. Preliminary results are promising, showing that this methodology might be used for the elicitation of human behaviour of subjects when facing an emergency. Moreover, the data acquired is of great importance for the fire safety experts designing new buildings or planning strategies to improve emergency paths. Another possible outcome is to create an artificial population based on human behaviour to populate emergency evacuation simulators.
