This paper proposes a smart object event modeling language. By attaching sensor nodes to everyday objects, users can augment the objects digitally and apply the objects into various services. When creating such smart object services, users should define events, such as beverage of a cup turns cold or someone sits down on a chair, using physical values from sensors. The most common event definition for end-users is simply describing threshold of sensor values and boolean operation. When they want to define more complex events, such as multiple people sit down on chairs or a user starts to study using a pen and a notebook, they need to use a programming language. To define such complex event easily without complex programming language, we present a new event description language called SOEML based on temporal relation among simple events. We also provide users a visual interface to support users defining or reusing events easily.
