A researcher, healthy young people and a diabetic each used the finished system, and some needed refinements became clear. The largest problem was the size of the screen and the size of the characters and figures to be input. With a PDA, it was impossible to solve this problem radically. But we can support for people of advanced age and the people who eyesight is reduced because this system can be used in all models in which PHP works by models with a large screen. The advantage of portability is lost by this, but the good point of this system is that it can support a wide range of situations where it can be easily used.In addition, information was accumulated in a database, and data analysis was enabled. This analysis is made use of for evaluation in self-care.A PDA was rented to four diabetics for about 1 month, and we asked them to input information about their self-care situation. They answered that all four of them understood how to use the PDA immediately, but, because of the problem of character size, one person was not able to continue using the PDA for one month.At the end of one month's evaluation we found the following positive results from using a PDA: a consciousness of self-care was strengthened, the PDA was better than writhing things down on paper, and the probability of continued self-care also seemed better. Our evaluation showed that they wished to continue using this system and confirmed the effectiveness of self-care support using a PDA. On the other hand, it may be thought that it is difficult for people of advanced use who have never used the Internet to operate a PDA and this is an issue that requires further investigation.
