A recent paper published in Frontiers reviewed the possibility to use Automatic Speech Recognition (ASR) from neural signals to produce textual representations of imagined words: http://journal.frontiersin.org/article/10.3389/fnins.2016.00429/full

The key concept of this brain-to-text technology is the capture of neural signals from the brain metabolic activity using Functional Magnetic Resonance Imaging.

While this system employs invasive technologies like EEG, I think the future of brain-to-text systems is to employ non-invasive technologies to process and analyze metabolic neural data from smart phones.

Any thoughts ?

In what way are EEG and fMRI "invasive" ?

In what way are EEG and fMRI "invasive" ?

EEG is considered "invasive" neuroimaging technology since it requires electrodes to be installed on the head of the patient to decode neural activity. In contrast, non-invasive neuroimaging devices (fMRI) do not requires electrodes to visualize functional brain activity.

Would you consider the metal-fasteners on your jeans "invasive".

Typical  EEG electrodes are similar, (they don't pierce the skin).

I feel clamping your head in position inside a noisy machine and subjecting you to a 4T magnetic field pretty invasive but if they want to get information from you it might be better than what interrogators traditionally do
