Active sensing research refers to the process where sensors or organisms actively gather information by interacting with their environment, distinguishing it from passive sensing, which relies on receiving signals without intervention. This field encompasses research on active sensing in humans, robotics, and computing systems, focusing on how information acquisition is optimized for perception and decision-making. As a key area within computer vision and multimedia computation, active sensing advances technologies that enhance sensory systems and autonomous behavior.
