Abstract
The tool of ICT (Information & Communiation Technology) set as the object of an information design is the tool which changes our activity from the basis.The design of the tool which can be used now is not made only by observing the activity currently performed now. Because such a new tool pulls out different activity.In order to know the essence of activity, we need to have a user "Telling" and "Sense" the true meaning of their activity. And it is necessary to structuralize the "event" currently "told" there. In this paper, it takes up a case study of the design for the support tool for rotation of crops, and how treated "Telling" and "Sense"are.
