Tactile Rendering

Definition

Tactile rendering is the process of generating and displaying haptic feedback to users through tactile sensations, allowing them to perceive and interact with virtual environments in a more immersive way. This technique enhances user experience by simulating touch, texture, and surface properties, making virtual objects feel more real. Effective tactile rendering can also improve user performance in tasks that require precise manipulation and control.
