In an Army Research Laboratory facility here called "The MIND Lab," a desktop computer was able to accurately determine what target image a Soldier was thinking about.
MIND stands for "Mission Impact Through Neurotechnology Design," and Dr. Anthony Ries used technology in the lab to decode the Soldier's brain signals.
Ries, a cognitive neuroscientist who studies visual perception and target recognition, hooked the Soldier up to an electroencephalogram - a device that reads brain waves - and then had him sit in front of a computer to look at a series of images that would flash on the screen.
There were five categories of images: boats, pandas, strawberries, butterflies and chandeliers. The Soldier was asked to choose one of those categories, but keep the choice to himself. Then images flashed on the screen at a rate of about one per second. Each image fell into one of the five categories. The Soldier didn't have to say anything, or click anything. He had only to count, in his head, how many images he saw that fell into the category he had chosen.
When the experiment was over, after about two minutes, the computer revealed that the Soldier had chosen to focus on the "boat" category. The computer accomplished that feat by analyzing brainwaves from the Soldier. When a picture of a boat had been flashed on the screen, the Soldier's brain waves appeared different from when a picture of a strawberry, a butterfly, a chandelier or a panda appeared on the screen.
"We want to create a solution where image analysts can quickly sort through large volumes of image data, while still maintaining a high level of accuracy, by leveraging the power of the neural responses of individuals," he said.
Dr. Anthony Ries instructs Pfc. Kenneth Blandon on how to play a computer game, using only his eyes to control the direction of fire of a bubble-shooting cannon at Aberdeen Proving Ground, Md., Nov. 3, 2015. Ries is a cognitive neuroscientist, who studies visual perception and target recognition. Blandon is a mechanic with the 20th Chemical, Biological, Radiological, Nuclear and Explosives Command.
