Scientists led by Rajesh Rao, University of Washington, have managed to do the first step to show, through a video game, that human beings can interact with virtual realities by stimulating the brain.
In this study published in the journal "Frontiers in Robotics and AI", the researchers describe what's demonstration of the first people to play a video game simply by using only the data coming from the stimulation of the brain, without using any kind of signal that comes out of sight, hearing and touch.
As in Matrix
Participants in the study must find the way to 21 different labyrinths, with two choices, walk straight or down, based on visual stimulation.
"But key question is whether the brain can use the artificial information that has not seen before and navigate in a virtual world or perform necessary tasks without stimulating the senses," says Rao.
"In fact the answer is yes," he said.
Five persons who participated in this experiment have conducted appropriate actions labyrinths in 92 percent of cases, when the signal received direct stimulation of the brain, compared with 15 percent of the cases that have not received this information.
This means that new information coming from the sensors generate artificial or virtual form can be processed and sent to the brain to solve the exercises.
"In the future this technique can be used to help people who have various shortcomings, but to pave the way for a more realistic virtual reality" concludes Rao
