kageinuyasha

as quoted by my friend shadow skeptic though no idea who he go it from "the key to the mind is a great en devour" means that the mind is yet to be fully explored so the first generation would probably be like that... but it could be like the one from SAO in the fact that japan is three centuries ahead in technology .

with this said you would need a test subject.. i suggest using a computer made brain... for example like they do in deadliest warriors where they have the human brain function in dummies so that they may test if a strike is fatal before actually using computer graphics to make the characters fight. the nerve gear is a simple yet complex machine so in order to achieve the quality that you want it has to be precise

if you study the human body the nerves are what makes the body feel hear touch and smell and all the nerves are inside the spinal chord but you wouldn't want to tamper with that due to the fact that the body would react and paralyze the gamer in question so you could use a harmless neuro laser to also get the effects you want though you would still need the limiter to make sure the gamer isn't affected by the system.

well to be fully honest you do not need to connect the brain to wires and hope that this will work ... in order for the full dive system to actually work you will need to simotainiously have the brain functions of touch taste hear smell and feelings all working within the nerve gear its self while also having it only touch the players head. in order to do that you will also have to know how the brain works along with the daily body functions of the human body so as no to cause an incident in the real world while the user is in game. so i suggest that we take a look back at sao they used micro wave particles to attach the user to the game in doing so they could have easily killed thousands of people but instead they tested the safety device that delutes the waves so that the gear is safe for use i think the very first step should be locating a safety device such as this then comes the console then the game. sorry english isnt my first language japanese is but i hope that you know what i meant. and to be honest you would also have to have a very strong fire wall too
