Hi all, I would like to express some of my opinions on this topic that I find rather interesting: first, I apoligize in advance for some of my lack of detailed knowledge about on some of these areas, however I agree with the "creation" of a kind of NerveGear kind taht exist in SAO, however the information read in this thread I could summarize a few points which,with current technology, we have several shortcomings. how were they developed VR devices like the Oculus Rift and Leap Motion, we done several "breakthroughs" in VR technology, however what I read I could deduce that the real problem of brain-computer interface is tied mostly to the sensations that you perceived, even(referring to the anime SAO) be aware while using a device such as the NerveGear, reproducing the impulse given by one part of our brain only for a specific fuction within the game/program, such as the articulation movement or through a movement to pick up an object, being able to feel the consistency and other data, and send that information to our nervous system. However, about the last topic that I have mentioned, we must always bear in mind not to block the functions of the hypothalamus (autonomous functions such as breathing and heartbeat) or other damage. In any case this modernization of VR tchnology can be useful in many fields including medicine (the most important in my opinion), even commercial, mentioning once SAO; related to the latter, by myself I started to do some surveys in the region where I liveif it could affect a play VRMMORPG according to different age groups, getting mostly a positive response; trade, however in my opinion, presents several disadvantages to a few factors: the addiction to the game, the cost of producing such world class equipment,...etc so even if this a secondary issue. However I would agree to work on such a topic, or more correctly, to give my contribution to a similar project, although I'm now finishing high school. I apologize for my bad English.
