But now a design student is suggesting that it could be possible
to have more, with a prosthetic third thumb to aid productivity.
The thumb is the brainchild of Dani Clode, a product design
student at London's Royal Academy of Art. She calls her
3D-printed Third Thumb a human hand extension.
"It's an exploration into human extension and human
augmentation, as well as better understanding the connection
that develops between body and prosthetic technology," she told
Reuters.
The thumb sits below the little finger, opposite its natural
counterpart, and straps on a like a watch. The device is
controlled wirelessly by sensors worn on the feet.
Clode says she was fascinated with the idea of using prosthetics
to augment the human body, rather than to replace a lost
appendage.
"I really like this idea of re-framing prosthetics as extensions
to the body rather than anything that fixes or replaces", she
said.
Clode says there are no plans to copyright or market the Third
Thumb and she sees it more as a thought piece and catalyst for
discussion.
