就職模擬面接による身体引き込み観客キャラクタを用いた実映像対話システムの評価

摘要

An embodied video communication system, called ’E-VChat’, was developed for enhancingremote communication using a video image. This system is constructed by the partner’svideo image using interactive CG characters including user’s own avatar and virtualaudience characters. We have confirmed the effectiveness of the system by an experimentunder free conversation. Furthermore, we developed an embodied entrainment audiencecharacters system with partner’s face to relate audience characters with the partner. Thissystem could bring about more active interaction by virtual audience even if the remotepartner does not respond to user’s speech. In addition, we confirmed the effectiveness ofthe system in which face images of partner’s face are superimposed on audience charactersunder free conversation with friends. However, this system is not always evaluatedeffectively in all situations including nervous situations such as a job interview. In thispaper, a communication experiment by a simulated job interview is performed for tenstudent subjects and one interviewer who works for a company, and the effectiveness ofthe system is investigated by the sensory evaluation.%遠く離れた家族や友人の顔を見ながらディスプレイを介して対話できる実映像対話システムは非常に有用であり，ネットワークの拡大とともに用途を増し，テレビ会議やWEB 面接などが普及しつつある．昨今の急速なスマートフォン端末の普及により誰でも手軽に動画撮影を行えるようになっており，Skype 等のビデオチャットアプリケーションをより手軽に扱うことを可能としている．
