INVESTIGATION INTO AUDIO-VISUAL ENVIRONMENTS FOR "KANSEI CONTENT" DEVELOPMENT

Abstract

Nowadays, we can stay at home and enjoy realistic movies and other multimedia content that is clear and full of realistic sensations. However, it is still difficult for amateurs to make multimedia content that can express their intention and idea to the viewer's Kansei, because techniques of making multimedia content depend on the producer's creativity and experience. In this research, we define “Kansei content”as multimedia content that is successful in conveying the producer's intended emotional component to the viewer. Using data of assessment results, such as data of audio-visual environment effects, we develop techniques for producing Kansei content. As the first step toward Kansei content development, we explore audio-visual environments in which multimedia content can better express the producer's intention to the viewer's Kansei. Subjective assessment experiment investigates how the viewer's feelings are influenced by relations among audio environments, screen sizes and multimedia content. In the subjective assessment experiment, we prepare four different audio-visual environments and eight multimedia content items, and subjects answer what impression they receive from each multimedia content in each of the audio-visual environments. According to 120 assessment results, differences in the audio environment influence the impression of the multimedia content more than differences in the screen size do. Moreover, the differences in the audio environment affect the impression not only for “audio”but also “visual, ”“storyline”and “audiovisual”aspects of the multimedia content.
