Brain to brain

and brain-computer communication.

Last revised 9/6/2014. Return to Major concepts. See interaction, cyborg, glasses.

A humor example of brain-to-brain communication, on the One Penny Sheet website, where one of the participants asks the other one "How do you do?".

Direct communication from brain to computer, and then to other human brains is no longer science-fiction. For several years now, we can find devices, simplistic perhaps, at low prices, and free software. As far as we know, neither scientists nor philosophers, nor even science-fiction writers see interested in this issue. We don't find anything in literature, when humanoid robots have been told about since Antiquity. Who will dare to go on this topic.

Present experiences or realizations can be classified as follows.
1. Corporal intrusion degree.
- no corporal intrusion, nor even physical device; it is the domain of telepathy, suggesion, hypnosis;
- non-intrusive sensors and actuators: headsets, goggles, contact lenses, mobile prostheses;
- intrusive sensors and actuators: implants and electrodes connecte to the brain and the neural system in general.

2. The communication direction: from outside to the brain( perception) and from brain to outside (action).

3. Relationship density
- bandpass, precision and semantic richness of transmitted signals.

4. Conscious and willful engagement
- no perceptible engagement; ideally the prosthesis, as any organ, lets itself be forgetted when it works correctly (liver as well as glasses);
- no engagement, but bad situations where the subject is controlled without knowing it, or triggers external actions without willing them;
- the neural system and the mind globally must be adapted to an environment which does not transits via the traditional sensori-motor channels; hence, for instance, the demand for haptics, the noise accepted tof computer keyboards, etc.; if we go quite far, we enter a "terra incognita" of relations with the world, and cannot find any help in historical precedents.


5. The part of digital art in these experiences
- Most of these experiences are presently games or medical cures (ans probably also military);
- some artists make experiences in this domain, but not yet convincing; see our dialog with Kiel Long, following a symposium at Brussels 'Imal de Bruxelles.
