Abstract
In this study, the effective methods of making user consider for environmental impacts who would select products were examined. First, through the case of television, the words concerned with product selection were sorted out by KJ method. Then using the third theory of quantification and the cluster analysis method, various televisions were classified into four groups in view of user's requirement. From a result, we suggested a plan which would urge the user to consider about the environment to each of the groups classified by the above-mentioned methods. By this means, we showed capabilities to deepen user's consideration for environment without contradiction to their requirements.
