The beam splitters and lenses are represented by physical objects, and the system projects down the laser beam path.

It will make our denominator 0.

(Laughter)

Uranium hexafluoride is a gas.

Google the App Engine Datastore actually has some of these limitations.

It's completely intuitive there's no instruction manual.

They're going to essentially turn into water and disappear into the solution.

So there must have been 1 mole of hydrogen to begin with.

Hit me.

We have so much technology nowadays that these interfaces should start conforming to us.

We have perception, computation and non visual interfaces.

And then you're going to do customer validation and actually see if your proposed solution actually matches what you think the customer problem was.

Now my question to you is, is this the most general solution?

This problem there are.

We're 25, 26 years after the advent of the Macintosh, which was an astoundingly seminal event in the history of human machine interface and in computation in general.

There's no interface, again. It really allows anybody to kind of go in and it just does what you'd expect, you know?

(Laughter)

Right?

We're not accessing it.

And it just sits there and burns for the 60 years, and then it's done.

The sensors that are used can see through the dark, the fog and rain.

So, think about strategic alliances.

The executives at these companies told me,

The next thing is you're going to test the solution, and you're going to test the solution if you're on the Web by building a low fidelity and then a high fidelity prototype, and you're going to again test your understanding of the customers' needs and whether your solution matches this.

The term Widget refers to the basic building block of a computer program's interface.

So for this, we developed many different types of non visual user interface technology.

I'm telling you it's there.

Then, on the side, we've got the Web and, increasingly, the cloud, which is fantastic, but also in the regard in which an interface is fundamental kind of a distraction.

What's really interesting here is what you can do with it and the kind of interfaces you can build on top of it.

You're going to test your understanding of the customer's problem or need, and you're going to figure out how to build the prototype.

They completely neutralize each other, and you have a completely neutral solution.

At that point, I've essentially eliminated all of the hydrogen ions that were in my original solution.

There's also companies like Google that are using the technology to create interfaces between mobile phones, tablets and the real world.

I mean it's been 25 years.

And, so, we have what I think is the easiest to use and I hope most enjoyable subtitling interface anywhere.

I thought, Why can I not connect the normal interface of a physical sticky note to the digital world?

I can do it simultaneously, holding this down, and gripping on another one, stretching this out.

Well we need a neural interface, a way to connect to our nervous system or our thought processes so that it's intuitive, it's natural,

Is it performance or cost?

So it creates this inflection in the graph, and you just would have to look at this chart.

So I'd like to show you a few examples, because there are many possible applications for this new interface.

But Alex was preparing a little, sort of obscure, indie, arthouse film called Minority Report for Steven Spielberg, and invited us to come out from MlT and design the interfaces that would appear in that film.

So let's look at these two situations and see if we get any solutions that make sense.

That is system integrators are designed to handle complex systems.

And so the phases of customer discovery start with stating your hypotheses, testing the problem, testing the solution, or verifying or pivoting.
