Gaze detection method and apparatus

A method for determining whether a line of sight of a user points to a direction of a region of interest in a 3D scene includes: providing the 3D scene including the region of interest; associating anattribute with the region of interest; creating a bitmap representing a location of the region of interest in a projection view of the 3D scene, each pixel of the bitmap to which the region of interest is projected storing an attribute of the region of interest; detecting the direction of the sight of the user; the bitmap is used to determine whether the detected user's gaze points to the direction of the region of interest. 一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。
