Can We Do More with Brain Waves Signal ?

More efforts for translating brain waves into words.

This is much to get debated over privacy in some extend, but we can set some limits over the usage, e.g. Only compulsory wearable to those below 7 y.o., under self-control over what to share, only sending out alerts to next-of-kin when distressed signal prolonged and exceeded the optimistic boundary.

Longing to communicate with a comatose patient? Eagerly wishing to locate a lost child to human trafficking and kidnapping? Wishing to understand your baby?

We can't deny every suggestion above is a wonder we hope to happen.

How much longer to go there from now?

Years ago, before I understand what neuro-linguistic programming (NLP) refers to, I simply thought it means we have managed to translate brain waves exactly into comprehendible language. But, it was not true. Multiple scientists tried to do that, but it was not very successful and accurate yet. That's a huge regret. As we claimed of how advanced we are, we cannot even decode exact information yet, be it just guessing the direction in degree of eye movement from the EEG data, we are just not exactly anywhere near yet. Big data approach does not seem to be very helpful in doing the task as well.

So, can we make deep learning do that? Can we just input the brain and physiological signals recorded and let the model learns against a subject's activity, say, starts by decoding whatever is handwritten by a subject based on match and prediction function in the initial testing of the model? Given that we have neural networks that able to predict individualized upcoming words, I think it worth a try. Moreover, given that not every model needs a validation set to work with these days, I believe it will not be way too long for us to get there. If we success, be it just 50% achievement, our time to use such 'tech' to investigate crime is not far either. Undeniably, if triumph and good lucks stay by our side, we would even able to let patients with declined motor ability to convey what they want to say or do in exact. By then, if we can ever rewind the time, maybe Prof. Stephen Hawking would get really happy with the invention too.
