The technology to control objects just by thinking about them is being developed in labs all over the world. But in Japan, a neuro-technology company is taking serious brainwave science and turning it into fun.
In Tokyo, they're all ears for the latest in hi-tech fashion.
The headware is called "Necomimi" - or cat ears in Japanese. And it doubles as a communication device.
Necomimi can be controlled by the wearer's thoughts and emotions.
Necomimi was created by a company called Neurowave. They're using basic, non-invasive neuroimaging technologies and adapting them for the fashion world.
Apart from the ears, Necomimi has two brain-wave sensors that can read the emotions of the wearer.
Red brain waves show nervousness or concentration. Green waves indicate a relaxed state of mind.
The ears shoot up when the wearer is nervous or focused. They flatten when the wearer is relaxed.
When a person is relaxed but also focussed on a specific activity like a game or reading a book, the ears swirl around in a circle. When brain activity is low, the ears just flap gently back and forth.
One of the creators of Nekomimi says she wanted to come up with a communication device that could be enjoyed by everyone. And in Japan, cats are popular.

"When cats are frightened or want to scare away an enemy, they flatten their ears. But with Necomimi, flat ears mean a relaxed state of mind. So we have changed the meaning to suit human perceptions. To humans, when cat ears flatten, it's kind of cute."
The science of neuro-control is being developed in labs all over the world. The aim is to help the disabled or victims of "locked-in" syndrome.
Neurowave says it plans to launch the Necomimi internationally later this year at a price of several hundred dollars per unit.
