The TouchPico is about the size of two large phablets stacked on top of each other. It's pocketable in the sense that a flask is pocket-sized; it'll fit, but you won't forget it's there. And it won't actually turn your wall into a touchscreen. That's the bad news.
What it does instead is project up to an 80-inch-diagonal screen on whatever wall you point it at. An included stylus with a clicky tip serves as your touch-device: tap it against the wall you're projecting on, and it sends an infrared signal to the projector registering your click. Try clicking with your finger, and the projector will do nothing but wait for you to quit messing around.
All the engineering and designing has been done, but Touchjet is turning to Indiegogo to raise money for the first batch of products. Backers will get the TouchPico projector for $350, with regular retail price set at $500 once the campaign is over. That's steep, but until someone comes out with an 80-inch Android device you can carry in your pocket, then hang on a wall, it's probably the best you're gonna do.
