Because the engine block is a totally different temperature.

But it's just something I know as I'm walking through.

I'm just...

feeling that information.

Or if I come across two chairs, I can tell which chair was more recently sat in because there's still a temperature signature on it and so on.

There's a million things about this that one can just come to perceive in new sense, but you can have much wackier things.

We've done, we actually have 70 projects

If anybody's interested, go to neosensory.com slash developers and you can see our blog of all these different projects we have.

So, you know, stock market or feeling social media with your skin or firemen or blind people or people with prosthetics or there's a million different projects we have where we're feeding in new data streams.

And you can come to have perception.

One of the things we've been doing is for drone pilots, where you feel the pitch, yaw, roll, heading, and orientation of the drone on your skin.

So it's like you're becoming one with the drone.

It's like you've stretched your skin up there where the drone is.

And pilots can become much better at flying drones this way, in the fog and in the dark.

And in fact, right now, I'm working with a couple of young engineers in Ukraine to implement this for their defense.

So this is a hypothesis that my student and I came up with some years ago, which is the following.

If you go blind, as we mentioned earlier, if you go blind, that territory or visual cortex gets taken over by neighboring kingdoms of data, like hearing and touch.

But the surprise in neuroscience is how fast this can happen.

So some colleagues of mine at Harvard did this experiment where they took normally sighted people and they blindfolded them and they put them in the brain scanner.

And what they found to their surprise is that after about an hour, they could start seeing activity in the visual cortex when you touch somebody or when you play a sound for them.
