This study aims to explore the elderly users’ preference for the transparency of the guiding diagrams in the phone interface and their use of the interface. In the one-to-one interview and the questionnaire survey, the subjects compared the guiding diagrams of two levels of transparency, and the statistical software was adopted to analyze and process the data obtained from the questionnaire. According to the results of the statistical analysis of the interviews and questionnaire survey involving 20 elderly people, there is no significant difference in the preference for transparency among the elderly users, and the effects of the transparency of guiding diagrams on the use of the phone are insignificant. The findings can provide reference for phone interface designers in the process of interface design.
