我们的眼睛看什么地方？在自然的、主动的视觉中，我们把眼睛移到场景中与任务相关的信息中。实际上视点落在信息最大的地方，即是减小局部不确定性。-How do we decide where to look next? During natural, active vision, we move our eyes to gather task-relevant information from

the visual scene.One strategy is to move the eyes to locations that maximize the total information gained about the shape, which is equivalent to reducing global

uncertainty. Observers’ behavior may appear highly similar to this strategy, but a rigorous analysis of sequential fixation

placement reveals that observers may instead be using a local rule: fixate only the most informative locations, that is, reduce

local uncertainty.
