In a UW experiment subjects were asked to navigate through mazes on the sole basis of the inputs that their brains delivered to them. This was done by a magnetic coil placed at the back of the skull. It demonstrated that how humans can interact with virtual realities using the process of brain stimulation.
Coinciding with plot of the movie Matrix, the researchers of University of Washington took the first step to show how humans can interact with virtual realities using brain stimulation.
The subjects of an experiment were made to play two dimensional computer games. They had to navigate through 21 mazes, with on two choices: forward or backward. The fundamental question, on which this experiment was based, was-Can the brain use unknown artificial intelligence to navigate a virtual world? It was found that yes that was possible.
The game demonstrated how novel information can be successfully encoded and sent to the human brain to do useful tasks. It is being said that over time this can help in assisting people with sensory deficits while also paving the way for more realistic virtual reality experiences.
