Description

In conventional video communications, gaze direction is not sent correctly and there is not proper eye contact usually. Most studies have tried to simulate it to real world. In this paper we propose a new approach of this problem. Creating the "ambiguously interpretative zone" of the gaze information, and presenting other information that helps to recognize whom the speaker looked at, listeners can select a correct gaze direction from the video image. Experimental result shows that the ambiguously interpretative zone can be created by controlling the video resolution.
