| description | The present invention can provide a device and method for predicting a VR sickness, in which a user head angular velocity, a visual angular velocity, and a perceived angular velocity are extracted as a perceptual motion feature from a VR content, a texture feature and a motion feature are extracted as a statistical content feature, and a feature vector is then configured and temporally pooled so as to predict a VR content sickness. Therefore, the present invention can objectively and accurately predict a VR content sickness showing a large individual deviation.
La présente invention concerne un dispositif et un procédé de prédiction d'un malaise VR, dans lequel une vitesse angulaire de tête de l'utilisateur·trice, une vitesse angulaire visuelle, et une vitesse angulaire perçue sont extraites en tant que caractéristique de mouvement de perception provenant d'un contenu VR, une caractéristique de texture et une caractéristique de mouvement sont extraites en tant que caractéristique de contenu statistique, et un vecteur de caractéristique est ensuite configuré et temporairement rassemblé afin de prédire un malaise lié à un contenu VR. Par conséquent, la présente invention peut objectivement et de manière précise prédire un malaise lié à un contenu VR présentant un grand écart individuel.
본 발명은 VR 콘텐츠로부터 사용자 헤드 각속도와 시각적 각속도 및 인지 각속도를 지각적 움직임 특징으로 추출하고, 텍스쳐 특징 및 모션 특징을 통계적 콘텐츠 특징으로 추출하여, 특징 벡터를 구성하고 시간적 풀링하여 VR 콘텐츠의 피로도를 예측함으로써, 개인적 편차가 크게 나타나는 VR 콘텐츠의 피로도를 객관적이고 정확하게 예측할 수 있는 VR 피로도 예측 장치 및 방법을 제공할 수 있다. |
