Japanese fashion electronics company Neurowear has developed Necomimi, a wearable set of cat ears that you can move with your mind to express emotions via sensors that detect signals from the brain. Here’s a rough translation of the product description from their website:
We created new human’s organs that use brain wave sensor.
“Necomimi” is the new communication tool
that augments human’s body and ability.
This cat’s ear shaped machine utilizes brain waves
and express your condition before you start talking.
Just put on “necomimi” and if you are concentrated on,
this cat’s ear shaped machine will rise.
When you are relaxed, your new ears lie down.
