Designing, Human and Computer Interaction, ElderlyAbstract
This research aimed to 1) study the guidelines for designing human-computer interaction that is friendly to the elderly and 2) design a human-computer interaction system that is friendly to the elderly. The sample group used was 25 elderly people aged 60 years and over by purposive sampling. The research instruments consisted of the experimental instrument, which was a human-computer interaction system that was friendly to the elderly. The application for health care for the elderly on smartphones was designed and developed based on the principles of human-computer interaction design. The data collection instruments included a user satisfaction assessment form and an assessment form for the ability to use a human-computer interaction system that was friendly to the elderly. The analysis of the needs of the elderly found that most elderly people had vision problems, which affected the design of font size, font colour, font shape, layout, and display of text data. Therefore, the font size, font colour, font shape, and layout were designed to be standard sizes that the elderly could easily and conveniently see. The results of the evaluation of user satisfaction with the application system for health care for the elderly on smartphones showed that overall satisfaction was at a high level ( = 4.39). The results of the evaluation of the usability of the application for health care for the elderly on smartphones showed that the overall usability of the system was at a high level (
= 4.41)
