Framework IDEA: princípios para condução de avaliação de dispositivos de interação voltados à tecnologia assistiva

Abstract

The Assistive Technology (AT) proposition for interaction with computers is still a big challenge, since the interaction devices need to be adapted to the user needs. This challenge is addressed by Human-Computer Interaction (HCI) field, which explores the design, implementation and evaluation of interactive computer systems. This thesis focuses on contributing to more inclusive principles in conducting assistive technology device evaluation experiments in Human-Computer Interaction area. Having as use scenario a device for computer access by people with head moviments preserved. To address this challenge, we first sought from the literature answers to how IHC evaluation methods focus on the disability issue. For this, a literature systematic mapping was performed. For the second moment, experimentation was sought to highlight how users make use of these devices and how devices are evaluated by existing methods. The research third stage involved results from MSL and hands-on experimentation to guide field research. Field research has allowed us to know and get the answers from the TA specialists who effectively prescribe, deliver, and follow up with a TA. Interviews with TA end users were also conducted to understand their reality and real needs. As a result of these three analyzes, theoretical, practical and field research, the IDEA framework was proposed, which consists of principles for conducting interaction device evaluation. To assist designers and evaluators of AT-focused systems with more inclusive procedures that address disability aspects. As a way of evaluation, a new experimentation cycle was performed to verify the IDEA framework application.
