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

Hit me.

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

So this is a musical interface built by a student from Italy, and he's now turning this into a product.

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

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

When they're laid out, I can pull things to new locations or delete things or just quickly sort a whole pile, you know, just immediately, right?

(Laughter)

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

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

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

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

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

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

We have perception, computation and non visual interfaces.

Now, this is an interesting little message, and it's a lesson that has since, I think, been forgotten or lost or something, and that is, namely, that the OS is the interface.

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

I'm telling you it's there.

Just imagine, in a classroom a teacher writes on the blackboard and a blind student can see what's written and read using these non visual interfaces.

As you can see, I can use the same two fingered gestures to go down and go in really seamlessly.

And one of the reasons why I think that is will be helped by things like graphics and visualization and inference tools, but I also think a big part of it is going to be having better interfaces, to be able to drill down into this kind of data, while still thinking about the big picture here.

We just came up with that on the spot, it's probably not the right thing to do, but there's such interesting things you can do with this interface.

I mean it's been 25 years.

It's a great example of the kind of research I really love all this compute power to make things do the right things, intuitive things, to do exactly what you expect.

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.

My orders are to take you there immediately.

And he published it. It wasn't locked up and disappeared.

They put them in foam, little containers.

We're not accessing it.

He died of an overdose.

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

The DOM is an interface to the structure of an HTML.document, for example, the head or body element.

I've got three rectangles here, and I also have their dimensions.

It has the frequency of roughly 12 cycles per minute.

So, the news stories that are all about the same topic get displayed together.

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.

And in fact, that's what we get.

The comparison here is simple.

This letter to Rogers is signed by Mr U N Owen.

Warning unsupported characters are displayed using the '_' character.

The ones I started were much more primitive.

The ones I started were much more primitive.

Look, I know you're scared.

So this led full circle, in a strange way, to build these ideas into what we believe is the necessary future of human machine interface the Spatial Operating Environment, we call it.
