A touch-sensitive robotic finger that can be attached to smartphones has been developed by a researcher in France.
The MobiLimb finger can crawl across the desk, waggle for attention when messages arrive and be used as an interface to control apps and games, according to BBC.
It can also stroke its owner on the hand, which developer Marc Teyssier said could create more personal connections.
He said people generally found the finger creepy or weird because it was so unusual, but hoped it would be "accepted" in time.
