Somehow these guys have used lasers to both track objects and draw as well.

I love this. A completely invisible interface that’s still perfectly intuitive. Who knew you could create a ground-breaking device that doesn’t even need an instruction manual! Amazing.

iPhone owners can use their phone to control an interactive advertisement.

While new ways to advertise to us usually don’t make me happy, this new technology is quite cool. The ability to walk up to any interface and control it with your iPhone is something with HUGE potential. I just hope someone jumps on this and makes it useful to us.

Imagine: Walking into In&Out and ordering your whole meal from next to the napkins. Or buying movie tickets and snacks then picking them all up at once. Or when you are looking at clothes, being able to see them in full controllable 3d before you even have to try them on.
Sure some would say this is just a way to make us lazier, but I think it’s a way to make us more productive with less work, thus increasing our ability to go do stuff that really matters. Or so I hope.
