An approach to designing ubiquitous systems that consider the user's diversity

Ubiquitous technology has great power to simplify and improve people's life. However, as the 4th Grand Research Challenge for the Brazilian Computer Society mentions, it is necessary to extend computational systems to all Brazilians, respecting their diversity and differences. Most studies in the literature consider the participation of users with different profiles during the design process. However, there is not a concern with interface adaptation to user's needs and interaction preferences. This paper presents a design process which guides the ubiquitous systems design from the relevant users' features identification to adapt the user interface, to the evaluation of the created prototype. The user's characteristics identification is performed by applying the UbiCARD technique in the system context to be developed. A prototype is presented as a proof of concept.
