| Summary: | 碩士 === 國立清華大學 === 工業工程與工程管理學系 === 96 === In recent years, mobile device such as mobile phone, digital camera, MP3 are becoming ubiquitous, especially for mobile phone which is the necessary product for modern people. With improved medical treatment, the floridisation is the trend of the world, and thus there are more and more old people may use mobile phones.
Physical limitation and cognitive limitation are two limitations when people get old, and these make elders confused, and thus the usual mobile phone can not satisfy the elders.
Therefore, the goal of this study is to design a mobile phone especially for the elders. First we use questionnaire to attain User-centered development. Then according to the questionnaire results, the mobile phone interface is designed and simulated by computer. The effect of the simulated interface is verified by an experiment. The results revealed that users searching time and error rate were reduced significantly. Besides, the users are more satisfied with the simulated interface. The results of the study verified that it would be beneficial to concern with user’s need while designing mobile phone interface. It is hoped that all elder users would enjoy the convenience with mobile phones.
