Sensory feedback

Definition

Sensory feedback refers to the information received by the human senses as a result of interaction with objects or environments, which is crucial for perceiving and controlling movement. This type of feedback plays a significant role in refining actions, enhancing precision, and enabling a better understanding of physical tasks through touch, sight, sound, and proprioception. In various fields such as robotics and haptic interfaces, it informs users about system performance and object characteristics during operation.
