ネット上の賛否表示へのピクトグラフ利用に向けた基礎検討

抄録

Pictographs are often used to provide statistical information, because they are easy to understand. They may also have the capacity of making users imagine another user's feeling and may promote a user to change his/her opinion with consideration for others' feelings, because a pictograph sufficiently represents a human's emotion. In our experiment, using a fictitious online opinion exchange system, we confirmed that randomly arranged arrays affect a user's feelings of others and opinion changes more satisfactorily than arranged arrays, when pictographs are used. The additional experiment showed that when characters and face marks were used as icons of pictograph, characters and angry face marks are more effective than rectangle and sad face marks. It is assumed that how an icon images the activity of various people is related to the effect of randomly arranged array for opinion changes and feelings of others.
