Virtual Space Creation System reflecting User's Emotion

Abstract

In this paper, we propose a new system reflecting user's emotion in a virtual space. In the system, a user inputs his/her emotion using 6 emotional parameters in detail, and he/she chooses some shapes of objects to exist in a virtual space. From these information, the proposed system reflects user's emotion in 6 aspects using fuzzy logic and weighted average calculation. The aspects are 1) an extent of the space, 2) background colors of the space, 3) colors of the objects, 4) size of the objects, 5) moving speed of the objects, and 6) the number of the objects. In the created virtual space, user can go forward, go back and turn as he/she likes. The system is evaluated by objective questionnaires by 13 testees and the effectiveness has been shown.
