The work aims to improve the interface design of current information terminals and enhance user experience for the elderly. First of all, information terminal processes were described with essential use cases. Based on the needs of the elderly, the evaluation system of information terminal interface layout for the elderly was constructed from structure, task and cognition. Then, the test samples were made according to the design research, an interface layout evaluation test for the elderly was conducted. Next, based on the results of the interface layout evaluation test, entropy weight method was used to determine the relative weight of evaluation indexes of the evaluation system. Finally, the test results were transformed into grey relational degree through the grey relational analysis, and the best scheme was determined by comparing grey relational degree. In this study, ATMs of the bank were taken as a case study, the results proved the applicability of the proposed method. Through the evaluation model of information terminal interface layout based on the entropy weight method and the grey correlation analysis method, the user preferences of the elderly can be quantified. It can effectively evaluate the interface layout of information terminals for the elderly, and has certain guiding significance for interface layout optimization.
