Facebook's coming up with a new way to constantly be on social media.

Its researchers are developing a device to allow users to feel messages through their skin.

The sleeve-like prototype translates words into vibrations delivered by pads onto the arm.

A paper published by Facebook points out "it can be devastating to miss important call, text, or notification from a loved one".

Researchers say their invention is needed to receive messages in situations when users can't check their smartphones, such as during a meeting, when in the cinema, or while attending church.
