I don't think that present resolution would be good enough for me ;) - I wish an option with small matrix of tiniest, more sensitive magnets, maybe of varying (resonance) sizes ? As a touch sense extension it seems intuitive to adapt - but feeling it more like a sound or colors, less as vibration then.. ? What about inducted solution - like a matrix of nanocoils calibrated to/messing with nearby neurons electrical levels to provide super precise feedback - or to feel it maybe like different keys being focused to press by mm movements ? ( reverse keyboard ?? )
