Phantom Haptics
Haptics is the science of applying touch sensation to interact with computer applications. Just as with phantom limbs the sensation of the limb is still felt, phantom haptics occurs when the sensations associated with an electronic device is still felt even when that device is not physically in contact with the body.
I have experienced phantom haptics when I am not wearing my Apple Watch. I still feel my watch telling me to stand up even though I am not wearing it.
