Abstract
It is frequently said that there is a regional difference in the use of high-tech device such as a cell phone. But the empirical evidence is few to be found regarding the detail of the literacy and the use of such device. In this paper, authors focused on the use of the cell phone by senior people living in Chiba City and Ishigaki City. The result of the questionnaire research showed that there are differences in the literacy and the use of the cell phone between Chiba and Ishigaki. Although the self-evaluations on the literacy for the cell phone were same for both districts, the substantial literacy level was high for Chiba. This is related to the difference in the life pattern and the environmental factors in both districts.
