Abstract

本研究の目的は生活用の製品を使用をしているときに生じる情動変化を顔面筋の筋電図計測によって推定することである.まず,顔面筋の筋活動を精度よく計測するために,多点電極を使用して筋の神経支配帯の位置を確認した.次に表情筋と咀嚼筋を同時に計測した.その結果,両者の筋活動は互いに密接に関連していることから,顔面筋の活動を計測する際には咀嚼筋の活動をモニターすることが必要であった.第3に閾値を設定することによって,顔面筋の活動レベルを2値化した.2値化された頻度によって快-不快の情動を定量的に表現した.応用例として,ドライビングゲーム中及び自動車運転中の顔面筋の活動を計測し比較した.その結果,アンケートから引き出せなかった情動変化が顔面筋の活動から計測できた.

The purpose of this study is to estimate the emotional changes in using the products for the life by electromyogram measurement of facial muscles. First, the position of innervation zones in each muscle was confirmed using the multiple-electrode in order to accurately measure the muscular activity of facial muscle. In the second, the activity of mimic muscles and masseter was measured simultaneously. As a result, it was necessary to monitor the activity of masseter, when facial muscle activity is measured, because both muscular activity were closely related to each other. In the third, the facial musculer activites were presented binary value by setting threshold. the emotion of pleasantness and unpleasantness was quantitatively expressed by the rate that presented binary value. As anapplication, the activites of facial muscles under driving game and actual automobile driving were measured and were compared. Emotionalchanges that could not be derived in the quwstionnaire could be measured from the activites of facial muscles.
