The ability to provide tactile feedback along with audio and video, while interacting with the virtual world provides a much better immersion. However, touch being an active sensing mechanism, researchers have been working on providing the sensation of touch through kinesthetic devices, once the 3D surface is defined. But how good is the force feedback? Is it slippery? Can we capture the surface texture? How well defined the surface has to be? What is the relevance of the force feedback to haptic perception? Are there any engineering applications of haptics? We shall try to explore answers to some of these questions during the talk. We shall begin by providing an introduction to haptics.
