PowerBook As A New Kind Of Human Interface Device
An anonymous reader writes "As covered earlier on Slashdot, Amit Singh had shown how to access and use the motion sensor feature in the late model PowerBooks for innovative things, which created quite a buzz in the Mac community. In an ingenius new article, Singh has taken the idea all the way and released software which lets you use a PowerBook with a motion sensor as a general purpose input device which works with existing apps. IMHO the coolest use of this is for playing games: be sure to check out the video footage in the article. For instance, in a car racing game, you steer by tilting the PowerBook left and right, go faster by tilting it forward, brake by tilting it backwards! You can also scroll in apps. Google Map scrolling with my PowerBook feels like flying in an aiprlane over the terrain. I must say you have to try this in real life to appreciate the experience ... go to the Apple store or something if you don't have the hardware ;-) Before this my girlfriend (who uses a Dell notebook) has never called anything computer related "jawdropping"! Wouldn't it be nice to have a gaming motion sensor be standard issue in all future laptops?"
What's even cooler about Amit Singh is that he's a he's a researcher at IBM Alamaden Research Center, working on, among other things, secure communications and Linux on the desktop.
And be sure to check out his other articles, particularly What is Mac OS X? . They're all well written, comprehensive on their respective topics, and generally excellent.
This article is fake. Note the following lie in bold:
"Before this my girlfriend (who uses a Dell notebook) has never called anything computer related "jawdropping"! "
This Porn Site is Powerbook Enabled ..yes, I can see a lot of new ways of interaction

How much good all this tilting and stuff does the hard drive. I'd think it caused some undue wear and tear, if not a head crash. Plus, to be picking up the whole laptop for use as an interface device seems a bit risky. Especially a Powerbook (you're talking around 2 grand there, Slim.)
You like your new Mac more than you like me, don't you, Dave? Dave? I asked...She said Yes.
Umm, actually, she was just yawning.
There are 0x40000000 types of people: those who understand 32-bit IEEE 754 floating point, and those who don't.
Depending on how you have your power settings, the HD is probably going to be asleep most of the time anyway. And the gentle motion you're talking about here is hardly going to be enough to phase a laptop drive - I've got a portable storage device that uses a laptop drive and had it sucessfully write a whole GB of data while I was walking quickly and had it in a pocket in my shorts.
In short, don't worry about the HD... slippery fingers might be a bit more of a concern but just be careful to do this above your lap, not held high in the air like a trophy.

There are 2 kinds of people in this world. Those that can keep their train of thought,
Well, no.
Don't get me wrong, this is a cool hack, but a 17" powerbook weighs over 3 kilograms.
You know how your Xbox controller was a bit big? Well, it wasn't that big.
~~~~~ BigLig2? You mean there's another one of me?
After (of course) parking the disk heads, I think that turning the laptop upside-down and giving it a good shaking should clear the screen.
I mean, wouldn't that just be common sense?
Other laptops may have had this for years...
So where are the Windows apps that make use of this sensor?
Apple doesn't even deserve credit for this one as they include the sensor for the same reason everyone else does. Apple does deserve a little credit for making the output of this sesnor accessible to the programmer, and then the guy that developed the initial software to make use of it deserves the lions share of the credit for saying "hey, what if I did this!".
In your rush to discredit Apple, you were a bit too hasty in dismissing the accomplishments of the programmer as well.

Yes with both you could bludgeon someone to death , however with the powerbook you could bludgeon in style whilst running OS X and with the sensor you would risk less HDD dammage whilst doing it
The only things certain in war are Propaganda and Death. You can never be sure which is which though

I tried it with John Madden's NFL Football. I threw a Hail Mary pass; a perfect, aim-for-the-end-zone spiral. My Powerbook sailed out the window of my 10th floor San Francisco apartment and I haven't seen it since.
I wonder if the pass was complete?

Consider tilting your laptop all over the place on an airplane. I''m sure it would annoy your neighbors to no end.
Actually, tilting the laptop didn't annoy my neighbors nearly as much as the airplane sounds I made, or when I'd headbutt the guy sitting next to me when I'd tilt my head along with the laptop.
The stewardess took my laptop away half way through the trip. Something about homeland security...

This is really cool from a UI perspective, but not entirely new. A couple years ago people were doing interesting things with tilt sensors for Palm devices. Also see: Nintendo's new WarioWare game for GameBoy advance, which has a rotational sensor built-in to the cartridge. Also, Sony has done research in this area as well.

I can see the powerbook/ibook sensors becoming popular amoungst laptop music geeks as a controller for interactive performances. (making the computer more and more like an instrument that can be played live)
Do you really want to be tilting a PowerBook around when you've only got one hand free?
Hate to sound like a phone geek, but my new Nokia 3220 with this standard mod has this feature, supported by 'Java motion' for programming, and ships games that use it...
Wow this is perhaps the most genius post ever, why didn't we think of just doing it properly first instead of spending decades improving technology step by step???
Surely your revelation will usher in a new era of computing. Hell before this we hadn't even been thinking thanks fsterman, thanks.
WARNING: Comment may include sarcasm in reply to a horribly naive and foolish post.
On Thinkpads the sensor is on the hard drive itself. The difference is that in PowerBooks it is on the motherboard, allowing it to be used with any hard drive and technically any hardware - e.g. Sudden Motion Sensing iPods...
