Abstract of Bachelor s Thesis Construction of action forecast system by usesing vital information Academic Year 2003 Summary I propose KALAS that guesses the user s behavior and does the action support measuring user s energy and motivation to act in this thesis. Recent years,the personal computer spread by the development of the information technology at the people.the development of the information technology has an influence big as for the workplace environment by it, and has changed the starting work form. Though the VDT frequency in which it works increases and the business processing speed improved, the VDT worker s influence on the mind and body came to be put in question. As for the VDT work, body tiredness and mental tiredness are large. So the worker s load increased, and the improvement of the working environment was needed. The system to support the worker inside is few though various approachs and systems are designed for the working environment improvement. Then, KALAS understood the worker inside by using worker s living body information. The action forecast is done based on it. Thus, doing support that suits the worker s desire becomes possible, and the worker s load can be reduced. In this thesis, KALAS was mounted with a living body sensor, and it evaluated it. The energies level was in real time judged with a living body sensor, the action forecast was done, and movement support target became possible at the right time. It was shown that the forecast accuracy improved by building the energies level into the action forecast. The technique of management the worker inside was able to be established by introducing the energies level.
