Rehabilitation of Data Web Application Design and Usability Evaluation for Elderly Users

Abstract

As nations face aging populations, elderly individuals often resist seeking medical care, negatively impacting their physical and mental well-being. Current telemedicine solutions often present unfriendly interfaces, exacerbating seniors' difficulties comprehending these technologies. To address these challenges, we developed a web-based application enabling elderly users to access rehabilitation data on mobile devices, gain insights into their rehabilitation training, and obtain medical guidance.Our methodology combined semi-structured interviews with seniors, on-site observations, and expert consultations to understand user requirements. We then conducted usability task experiments to assess key usability metrics, such as satisfaction, efficiency, and error rates. Finally, we employed a usability questionnaire and semi-structured interviews to evaluate the application's usability and seniors' motivation.Analyzing the completion of five predetermined tasks and the results of the MAUQ questionnaire, our findings demonstrated good overall usability for elderly users, with an average score of 5.20 per question. Using an independent sample T-test, we found that although the total questionnaire score remained unaffected by respondents' education level, significant differences arose concerning ease of use and satisfaction among respondents with distinct educational backgrounds.Our study highlights that the web application enhances older adults' willingness to use mobile devices for rehabilitation. By integrating the application into geriatric rehabilitation training, healthcare providers can facilitate a deeper understanding of seniors' conditions, increase motivation for rehabilitation, and streamline the process, making it accessible, digital, and visually engaging.
