Hitachi has successfully trial manufactured a lightweight, portable brain scanner that enables users to keep tabs on their mental activity during the course of their daily lives.
The system, which consists of a 400 gram (14 oz) headset and a 630 gram (1 lb 6 oz) controller worn on the waist, is the result of Hitachi’s efforts to transform the brain scanner into a familiar everyday item that anyone can use.
The rechargeable battery-operated mind reader relies on Hitachi’s so-called “optical topography” technology, which interprets mental activity based on subtle changes in the brain’s blood flow.
In addition to health and medical applications, Hitachi foresees uses for the personal mind reader in fields such as psychology, education and marketing.
The technology could also be used in new forms of entertainment such as “mind gaming,” where the player’s physical brain activity becomes a part of game play. It is also feasible to integrate the brain scanner with a remote control brain-machine interface that would allow users to operate electronic devices with their minds.
