From my Boston Globe column this week:
Wearing what looks like a swim cap wired with electrodes, you can “command’’ a robot to move left, right, and forward by looking at corresponding areas on a computer screen, the Northeastern researchers say.
Here’s how it works:
Each quadrant on the user’s computer screen represents a different command and flashes at a different frequency.
Staring at a particular quadrant causes the user’s visual cortex to emit a corresponding frequency, which a computer translates into a directional command.
The system then wirelessly transmits those commands to the laptop on the back of the robot. (The user can track the robot’s whereabouts by using a Skype video connection with the laptop.)
