I really wish that interfacing with the nervous system was easier.
It can be, at least for inputs back to us, just not via direct nerve interaction like brain gate/Kevin Warwick’s stuff - but we already have access to a super large sensory organ largely unused for information throughout and encoding.
Ian Davis also considered using a method similar, via haptics feedback based off pressure sensors on the fingers - although I don’t think that went far.
I’ve been poking around at figuring out ways to construct and ingest new signals as an interface - getting close to software release that would enable others to more readily do similar and play around even easier like I’ve been doing.
Sensory Weaver might be of interest, for further references there.
Haptics stuff is also what some prosthetics already are using and have been for a while, the field overall has lots of literature available for best ways to do it for different uses (well, common uses - stuff for extra augmenting isn’t so common)
