The document discusses haptics, which is the science of touch. It defines haptics as deriving from the Greek word meaning "being able to come into contact." The document outlines different types of haptic feedback including tactile and force feedback. It discusses how haptic devices work and how they are different from other input devices in providing both input and output. Examples of commonly used haptic devices are also provided such as exoskeletons, cybergloves, and Phantom devices. Applications of haptics include virtual reality, telepresence, games, surgical simulation, and military training.

1) It is the technique to compute the interaction
forces b/w the haptic interface and virtual
object.
2) Ensure that the haptic device correctly renders
such forces on the human operator.
