Haptics:
Haptics (pronounced HAP-tiks) is the science of applying touch (tactile) sensation and control to interaction with computer applications. The word derives from the Greek haptein meaning “to fasten.” Haptics offers an additional dimension to a virtual reality or 3-D environment and is essential to the immersiveness of those environments.

Reminds me of the old BBS days, when it was easy to offend someone because body language, inflection, etc, simply didn’t come through the telecommunications channel.
But I suspect the haptics folks are working on that.
