Usability and accessibility are key success factors for systems, which are developed for the Active and Assisted Living (AAL) target group. In order to maximise the uptake of the software solution implemented in the iCareCoops project, a broad study of usability and accessibility was conducted. A literature review revealed significant shortcomings in concrete implementation guidance across current publications and usability standardisation (WCAG, ISO). The subsequent low-fidelity prototype tests aimed at resolving the knowledge gap through extensive feedback from representative end-user groups. Paper prototypes of the user interface based on literature insights and early concepts allowed for a hands-on experience for participants. Thus, the test resulted in very specific instructions and recommendations for the user interface (UI) implementation. Due to the lack of literature on the practical implementation and the fruitful outcome of the iCareCoops process, we propose a best practice approach for future AAL solution development employing a mix of quantitative questionnaires, qualitative, semi-structured interviews, thinking aloud tests, and goal-driven evaluation with clear usability criteria, measurements and pass-fail indicators. |
