Hefestos: um modelo para suporte à acessibilidade ubíqua

Abstract

Nowadays, the wide range of available mobile devices, from various types, capabilities and technologies, associated with the profusion of wireless communication networks, allows the services offer anywhere and anytime. Although some research areas such as education, business, medicine, games and entertainment have been developed with the adoption of these technologies, the accessibility area still lacks of similar studies. Therefore, this dissertation proposes a model for accessibility support called Hefestos which uses ubiquitous computing to manage resources for elderly and People with Disabilities? (PWDs) accessibility. Various scenarios of everyday life are also described in this dissertation, where the Hefestos model can be applied, and the prototype of the smart wheelchair, called Hefestos Wheelchair, which was implemented to evaluate a scenario related to wheelchair users. Ultimately, the results obtained in the practical experiment are presented, with the participation of wheelchair users with a range of disability degrees, whose main goals were to evaluate the usability and functionality of the prototype and the acceptance to the proposed model.
