Sony wants to make your table interactive.
This projector senses depth, and responds to gestures.
It could also see objects you put on the surface.
It goes by the name of Concept T. And can do some cool things, like act as a house simulator.
The blocks represent the stories of a house.
So you can remove one at a time to see the floor plan, or wave your hand overhead to block the sun.
Try your hand at some classical musical with cylinders, put them in the right spots, and music starts to play from the projected speakers.
Isolate instruments, and make them louder by touching the round blocks.
or try an Alice in Wonderland game with an interactive book.
Tap the characters and they come to life on the table.
But Concept T is just that, a concept for now.
It's supposed to give us an idea of what to expect from future products.
And if you do want a taste of this in a real device, Sony's Xperia projector uses some similar tech and turns the surface into a giant touch screen.
