As a representative device of ICT-related devices and systems, authors selected the mobile phone for our research. Authors started their analysis from the questionnaire research roughly focusing on the use of mobile phone. As a result, it was revealed that the elderly people have low literacy for using the mobile phone compared to the young people. Furthermore, the elderly people living in urban area have higher level of mobile phone literacy, while those who are living in rural area tend to rely on others, especially young people. In order to analyze the difference between urban are and rural area and between young people and elderly people, authors then conducted a field survey adopting the contextual inquiry and analyzed the data by applying M-GTA, then summarized the information as a category relationship diagram. In the diagram, such factors as the motivation for using mobile phone, the active involvement to the communication and the mobile phone literacy were regarded as the principal components.
