Task description is essential in performing task analysis which is required for designing man-machine systems. Currently, there are many methods to support the task description which is very complex and time-consuming. However, these methods contain some problems such as being hard to understand and a lack of description. This research deals with an object-oriented task description(OOTD) method trying to solve these problems effectively. The OOTD method includes an object-oriented task structure diagram and an object-oriented task attribute diagram. The former shows some relationship between a task and a derived task. The latter includes important attributes to define each task.
