The day where we are connected to your computer through a neural interface is not far off. If they can correct the speech of a kid through deep brain stimulation then injecting data into the mind and reading from it is not far off. source
The current interface of Emotive is currently just reading electrical impulses on the outside region and does not give the resolution of a MRI.
A MRI can give you the resolution since it can see all the electrical pulses deep inside but the equipment is massive. With the correct software one can map the neurons for each person. This has been done to a point where they have a set of videos that can randomly play to a viewer inside a MRI and then extrapolate a fuzzy image read from the brain of the video playing.
It is not to much of a stretch to think mind control avatars in a game or injecting the game into your mind. This is scary and can be abused.
Still I am excited and waiting for the tech to be developed by researchers. I’ll do my part of working on data and vision linking through data fusion.
