Uma proposta de design da interação multimodal para e com a terceira idade para dispositivos móveis

Abstract

The use of small mobile devices such as smartphones and tablets has been growing in various public in Brazil. Even though many devices have features such as touch, gestures, voice, many applications do not adopt such resources to support different ways of interaction. Among the various audiences that have been using the mobile devices in Brazil, it can highlight the elderly person. To understand the needs of elderly audience is important not only observe their actions as well as brings them to inside of the process of development. User Centered Design (UCD) is a methodology that uses models, methods and processes for software design aiming to fulfill the user needs, composed by the steps of research, development and evaluation. Based on the UCD principals, this work presents an approach to support the design of interaction which besides being to the user, is also developed with the elderly user adding to the UCD cycle the techniques of participatory design and of personas. The application developed by the approach allows the elderly users to use the multimodal interaction according to their preferences and to the context of use. The methodology of this work was composed by three steps. First, a systematic review gave the support to the fundamentals and to the delimitation of the work scope. After that, the approach was designed based on UCD method including the participatory aspects. The proposal verification was conducted following the approach phases with the participation of a total of 279 elderly users. The results show that the elderly user, as a active member of the development process, aiding on the identification of real interaction aspects of the application.
