3-D Emotion Space for Interactive Communication

Fumio Kawakami; Motohiro Ohkura; Hiroshi Yamada; Hiroshi Harashima; Shigeo Morishima

In this paper, the methods for modeling facial expression and emotion arc proposed. This Emotion Model, called 3-D Emotion Space can represent both human and computer emotion conditions appearing on the face as a coordinate in the 3-D Space.

Studies on an optimal presentation mode and appropriate contrast level for a CRT display.

Satoru Kubota; Motohiro Ohkura

CRTディスプレイの表示モード (陽画表示と陰画表示) について, 視作業のパフォーマンス, 視覚負担などの点から比較検討した.実験1では, さまざまなコントラスト条件を設定し, 両表示モードを比較した.結果は, コントラストが極端に低い場合は, 陽画表示の方が陰画表示よりも作業パフォーマンスが良い.しかし, 適正なコントラストが確保された条件では, 表示モードの違いによる作業パフォーマンスの有意な差は認められない.瞳孔径は, 発光部分の輝度およびコントラストが等しい条件で比較すると, 陽画表示の方が陰画表示よりも0.2~0.3mm小さい.両表示モードとも, 管面外光反射輝度が2~21cd/m2の範囲では, 適正コントラストはおおむね5 : 1~20 : 1の範囲にあると考えられる.実験2では, 表示モードと視覚負担の関係を検討したが, 適正なコントラストが確保された条件では, 表示モードの違いによる視覚負担の有意な差は認められなかった.
