GAZE DETECTION METHOD AND APPARATUS

A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a pr...

Zusammenfassung:A method for determining if a user's gaze is directed in the direction of a zone of interest in a 3D scene comprises: providing a 3D scene containing a zone of interest; associating a property with the zone of interest; creating a bitmap representing the location of the zone of interest in a projected view of the 3D scene, each pixel of the bitmap to which the zone of interest is projected storingthe property of the zone of interest; detecting the direction of the user's gaze; using the bitmap to determine if the detected user's gaze is directed in the direction of the zone of interest. 种用于确定用户的视线是否指向3D场景中的感兴趣区的方向的方法包括：提供包含感兴趣区的3D场景；将属性与该感兴趣区相关联；创建表示该感兴趣区在3D场景的投影视图中的定位的位图，该感兴趣区所投影到的该位图的每个像素存储该感兴趣区的属性；检测用户的视线的方向；使用该位图来确定检测到的用户的视线是否指向该感兴趣区的方向。
