Outline of Final Research Achievements

In this research, an original algorithm that predicts the future state of recipient’s activity was developed to detect a medication error (e.g. a recipient occasionally overdoses or forgets to take medicine) while going out. The future state was estimated based on data measured by a variety of sensors in a smartphone such as an acceleration sensor, a gyro sensor, an ambient light sensor, a touch panel, and a barometer. The data were converted to feature quantities, which do not correlate with each other, by principal component analysis and were entered into a Bayesian network for activity state estimation. The target value of accuracy of estimation was set more than 70 percent, but it was not achieved. The main reason of the bad result was that eating-related states were so difficult to be predicted only by using the above sensors.
