Rather than projecting from the back of the room to the front, the Short Throw Projector projects on the wall it's nearest to.

The projector uses SXRD laser technology (yes, frickin' laser beams) to render a 4K image on the wall.

Turn the lights out, and you've got a real movie theater experience. And unlike with a standard projector, you don't need to worry about ceiling mounts, or a ceiling fan, getting in the way of the beam.

The Short Throw Projector was presented at CES as part of Sony's Life Space UX concept. Here, the projector is working in concert with a ceiling-mounted projector and a wall screen (on the right) to present a single "sunset" motif.

Another motif for Life Space UX: an underwater theme.

Yet another theme: a Paris street scene.

About that side panel we mentioned earlier, it doubles as a decorative mirror when not in use. But activate the touch screen, and ...

...Once activated, it's yet another touch screen.

On the other side of the Life Space UX room was the ceiling-mounted table projector. Here, the downward-firing projector is built into the light fixture, and displays objects on the table.

It's yet another take on the idea of a "Minority Report" interface; you can manipulate the projected objects on the table via touch.

While Life Space UX was among the more impressive tech in the room, it's not expected to reach consumers anytime soon.

So that's the deal with Sony's 4K Ultra Short Throw Projector and the Life Space UX. But if you don't have 50 grand to spare on such things, don't despair.

At IFA 2014, Sony debuted a smaller, more portable, and presumably less expensive model of the same concept. The Portable Short Throw Projector is also on the horizon. This one was part of a smart-home demo, and we don't have an expected launch date or price yet. But whenever it does come around, it will show a 23-inch image, and it's waterproof, so you can use it in the bath.
