"Honda Says Brain Waves Control Robot"

The machine for reading the brain patterns also would have to become smaller and lighter - like a cap that people can wear as they move about, said ATR researcher Yukiyasu Kamitani.

What Honda calls a "brain-machine interface" is an improvement over past approaches, such as those that required surgery to connect wires. Other methods still had to train people in ways to send brain signals or weren't very accurate in reading the signals, Kamitani said.
