This would allow for some immersive avatar features such as a gun vibrating when shooting, bow vibrating when you're drawing an arrow on a bow, or vibrations when high-fiving your friends.
For example, using contacts to detect your hand hitting another hand, having a toggle on the contact component for "haptic vibrate on-enter", or maybe a more indepth state behavior component for the animator, and boom you got a super immersive high-five :-)
