Gadgets: How long do you think till our cell phones will be able to project an HD image onto a surface, effectively creating a portable theater anywhere?

This TED talk is a fantastic look at projector/cell phone/gesture interface research. Brilliant.

I believe the future is now.

The sheer amount of power you need to project an image in a normally lit room, let alone outside, means we won't see that until we get drastically better power sources and light sources than we have now. You're talking a couple of orders of magnitude higher power use than a normal smartphone. You'd need a ridiculously efficient light source to get enough light out without the waste heat melting the phone or your hand.

Unless, that is, your definition of "anywhere" is "any dark room" in which case it won't be long, I suspect. You can already get compact cameras with (shitty) projectors built in.

When the power available to such devices is not limited by lithium batteries. New super-capacitor powered devices will permit the light intensity required for this.

First they need blue lasers on a chip that are as bright and energy efficient as the red laser pointers. Red and green are ready for production now.

Digital cameras have had this for over a year now:

There's projecting an image, and then there's projecting an image. I doubt cell phones will ever be able to project a high quality image with sufficient brightness, partly due to technology, and partly due to the added cost of putting something in there like that which most users wouldn't use. On the tech side, consider that currently a projector uses a very bright and hot-running bulb. The bulbs themselves run anywhere from $300+, and require a fan in the projector to cool them, not to mention the power requirements. I doubt you'll ever see a cell phone that can project a 100" picture on a wall 14 feet away with sufficient brightness and clarity to consider it HD.

A couple of years until the low-res versions are common.

HD seems like a lot to ask, but those engineers can be very tricky indeed.

Not long. I think the bigger challenge is how to get big sound out of a pocket sized device. I could see directional sound as a personal solution, but wouldn't really work for a crowd as well.

12 years for a 2k projector in a phone is my guess.
