The development of better eye and body tracking systems, and more flexible virtual environments have allowed more systematic exploration of natural vision and contributed a number of insights. In natural visually guided behaviour, humans make continuous sequences of sensory-motor decisions to satisfy current goals, and the role of vision is to provide the relevant information in order to achieve those goals. This paper reviews the factors that control gaze in natural visually guided actions such as locomotion, including the rewards and costs associated with the immediate behavioural goals, uncertainty about the state of the world and prior knowledge of the environment. These general features of human gaze control may inform the development of artificial systems.
更好的眼睛和身体跟踪系统以及更灵活的虚拟环境的发展,使得对自然视觉进行更系统的探索成为可能,并带来了许多见解。在自然的视觉引导行为中,人类会做出连续的感觉运动决策序列以满足当前目标,而视觉的作用是提供相关信息以实现这些目标。本文回顾了在诸如行走等自然视觉引导行动中控制注视的因素,包括与当前行为目标相关的奖励和成本、关于世界状态的不确定性以及对环境的先验知识。人类注视控制的这些一般特征可能会为人工系统的开发提供参考。
