Abstract
A household accounting system should be a "tool for thinking" to create an economical plan for the future. We propose a new household accounting system that visualizes expenditures and incomes through the placement of rectangles whose areas are proportional to the money amount: Thus, the user can arrange, move, cut off, and connect each item and grasp the state of a family budget. The purpose of this system is making a user look back to the balance of payments naturally by acquiring some awareness through interaction with each item. In this paper, we tested the proposed system by the input and arrange experiment and we describe about the result of long term use.
