Concept

haptic feedback

A hand gently cradles a glowing, wavy object against a soft, starry background, symbolizing the concept of haptic feedback in a futuristic, tactile interface.

The transmission of tactile sensations—such as resistance, texture, and tension—back to the user of a tool or robotic interface. In conventional surgery, this tactile response is essential for judging the fragility of tissue and the tension of a suture. The absence of true haptic feedback remains the primary limitation of robotic platforms.
