Brain-machine interfaces

This article on independent.co.uk is about a Japanese initiative to develop head-sets with sensors which can detect certain kinds of brain activity, allowing devices to be controlled by brain activity.

According to the article, the Nikkei daily has reported that the Japanese government plans to have mind-machine interface devices, co-developed with a consortium of Japanese companies, available within a decade.

New technology like this can provide a variety of story options for cinema and fiction. For example, a character could learn through familiarity with such devices and how they work that intricate details that the character thought they knew about supposed mechanical processes of the mind and how people relate to one another is just unfounded speculation.
