我们提出了一种在虚拟人类中自动生成自下而上的视觉注意行为的系统。自下而上的注意力是指环境引起人们注意的方式，而不考虑任务级别的目标。我们的框架基于多个组件的交互：用于感知虚拟世界的合成视觉系统、用于感知刺激的早期视觉处理的自下而上注意模型、用于存储先前感知数据的记忆系统以及用于生成结果行为的凝视控制器。我们的目标是通过赋予代理关注周围环境的能力，在有人居住的虚拟环境中提供一种临场感。
We present a system for the automatic generation of bottom-up visual attention behaviours in virtual humans. Bottom-up attention refers to the way in which the environment solicits one's attention without regard to task-level goals. Our framework is based on the interactions of multiple components: a synthetic vision system for perceiving the virtual world, a model of bottom-up attention for early visual processing of perceived stimuli, a memory system for the storage of previously sensed data and a gaze controller for the generation of resultant behaviours. Our aim is to provide a feeling of presence in inhabited virtual environments by endowing agents with the ability to pay attention to their surroundings.
