Haptic Rendering

Definition

Haptic rendering is the process of simulating the sense of touch through technology, enabling users to interact with virtual environments in a tactile manner. This technique enhances user experience by providing realistic feedback during interactions, which is especially crucial in applications like surgery, where precise movements and sensations are essential. By integrating haptic rendering into robotic systems, surgeons can receive feedback that mimics real-life sensations, making the virtual experience more immersive and intuitive.
