| Abstract(in English) | Nowadays, approximately 75% of all employees in industrial countries are required to work in a seated position. According to a report, long-term seated position is suggested to have the relationship of health index and 28% of office workers have chronic low back pain. It is therefore important for office workers to take a break at an appropriate timing. To estimate office workers’ seated state automatically using Machine Learning, we must collect a lots of training data for obtaining a good performance. It requires however much labors and costs. In the present study, we present a method of automatic training data collection for Machine Learning using a smart phone attached to a person and accelerometers installed on a chair. On experiment of automatic training data collection, the average accuracy has shown 98.4% and this indicates that our method has reached a practical level. |
