".....and when you're battery's running low."

Which is something you'll become accustomed to with this running.

brilliant.

that guy w/ the "keys in his pocket" has the weirdest gait ever! he was sauntering up the stairs.

It should be adapted to help me silence my cell phone when I don't want to take a call. Kind of like shaking a baby to keep it quiet.

so let me get this right. I put my hand in my pocket and shake my phone and it makes a noise. thats not going to make me look like the pervert I really am!!!!!!!

Just because looking at battery meter is too confusing for some people....

useless

Well, tremendously useful for most people this is not. But it's an interesting development of haptic interface and I can see some utility for people like me who keep their phone silenced most of the time. There's something about the idea of shaking it and feeling a lot of email sloshing around in there that I kinda like.

And of course for the blind this would be very handy.

Look at the bouncing balls, boy I'm glad I don't have the need to pay for fake ones.

@Y2KGTP: Ding!

This is a neat concept, but it's not practical most most people save perhaps the blind.

I think it's a pretty cool idea, although I'd have to agree that it doesn't look good for battery life.

I really like this trend of exploring alternative input and feedback. The ideas aren't always practical, but you just have to think up some wacky stuff sometimes in order to come up with one really good one.

That's not even a phone in the video... It's an iPaq5555/5550 (PPC). So the only real use is for battery life?

that's the stupidest thing i have ever seen, it's like a baby rattle and that guy
has the gay, gay, gay, gay gayist walk, too

I got that PDA (HP H5550) but I can see they have mounted some kind of accesory backpack on it.. could be bigger battery... could be a SD/CF card expansion for their motion sensor. if they got any

Oh PUHLEEZE!!
Stick some bells in a can already!
Hi-tech-dreck!
