6 Conclusion
Smart houses with a sensor network and domestic robots were built to take care elderly
people living alone. Many simulation tools have been proposed to help smart house
developers test and verify their designs, but it takes time and effort to build a simulation
scenario, and developers need to repeat scenario-generation procedures if they want to
use multiple simulators. To address these issues, we proposed a simulation tool that
provides diverse simulation scenarios and enables developers to build scenarios
automatically in multiple simulation platforms [11].
In this paper, we proposed an activity schedule generator that is an essential part of
our simulator. With an improved motivation-driven method, the generator produces
diverse daily activity schedules to mimic the daily lives of residents living alone. It
outperforms existing generators in three aspects: 1) it is adaptive to the layout of a
