the kochler implants that people have been tinkering with for while are really neat (implanting electrods to supplement a sense – lost vision for example) and i’ve been interested in the subject. occasionaly i’ve asked my friends which senses they’d like to have if they could pick and chose, and beyond the obvious ones (better hearing or vision) they are an unimaginative lot. i’d like to sense air currents. this isn’t of much use unless you’re flying or skydiving, but i imagine it would be cool.
wired has a very nice article summarising some of the development and innovation in the field. read it here: wired.com article
