Generation of emotion spaces based on the synesthesia phenomenon

This paper describes an investigation of the generation of surrealistic spaces that aim to achieve a new communications environment in which people can mutually convey their thoughts, mental images, and emotions more effectively. Emotion spaces here can be compared with conceptual spaces in the analogy of "logos versus pathos." Our focus was on the phenomenon of synesthesia, and the results shown are the tests of color image creation involving "tanka" (31-syllable Japanese poems), aiming at the generation of spaces where some emotions are reflected rather than concrete scenes imagined from word meanings. In addition, this paper proposes an application that judges the similarity of pieces of music, showing the possibility of making instant, subjective judgements without need for a performance.
