Abstract

Ordinal TVs or PC monitors are used to present images. However, these image-presenting equipments are fixed and cannnot be moved and rotated. When pictures present with shooting angle based on audiences' looking position, their presence will be much higher. In this paper, we investigated the method for improving presense by using moving-projecter and roaming images. To represent the camera shooting angle, we used optical flow. An optical flow method resulted in errors of 7.5% of the camera directions, which was accurate enough for our purpose. Furthermore, we compared exisiting presenting method (non-moving) and our method (moving). Six subjects participated in this experiment. The result indicates that our method could help understanding of the positions of objects in images more precisely. We can say that the proposed method is effective to improve presense.
