As more and more people face mobility constraints due to the natural aging process of the population, barrier-free planning becomes an important urban planning issue. It is elemental to know the place of spatial barriers associated with the negative emotion - the “stress” of probands. To achieve this, a method of psycho-physiological monitoring was developed, using a special technical device to measure autonomic bodily functions as indicators for emotions - a Smartband. This chapter presents the main characteristics and the outcomes of two projects that have applied the method, one in Germany and the other in Brazil. Future research directions are also discussed in this chapter. In summary, the next steps are to automate the interpretation of the collected data and to combine the existing methods with the development of a smartphone-based app to allow people to give some qualitative hints about urban parameters.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
