Detection of situations of danger faced by old pedestrian in urban space via the segmentation of sound scenes
Abstract
In a context of an international interest for the question of urban spaces accessibility for elderly, we tend to construct an experimental protocol correlating data issues of commented walks, psychophysiologic measures of stress level engendered by the crossing of some dangerous urban configurations and signal processing. This treatment is declined under multiple graphic representations allowing detecting in two dimensions those situations of danger. Through this protocol, we intend to characterize the informational content of urban sonic ambiances. The emergence of sound events that may announce a dangerous situation can be represented and we can guarantee to seniors with hearing loss a serene using of the city.
