Having Fun With PowerBook Motion Sensors
mjk325 writes "Amit Singh has published a discussion on the 'Sudden Motion Sensor' feature in the latest revision PowerBooks. One utility he has released displays a 3-D view of the PowerBook that follows the actual movement of the physical machine. Another utility creates windows that rotate in opposite directions to the physical machine to appear always straight. My brand new PB has the motion sensor, but apparently the utilities work on any system using software faking."
This is cool enough to make me want a PowerBook.
Seems like this could be used to implement some sort of security feature. Turn on a utility, and when significant movement is detected the computer could send out a signal- in the form of activating an attached alarm, taking a picture with a webcam and emailing it, etc etc. When the owner returns, the utility could be quickly turned back off.

Obviously, you all have no imagination.
What is clearly needed is a plug-in that clears the screen when the unit is held upside-down and shaken!
Or a version of Marble Madness that uses the tilt of the machine to control the marble.

Tilt games using ball bearings need to be developed as soon as possible to make use of this.
The pBook is light enough to make it feasible for a little while anyway. My only concern would be causing the drive heads to park to often due to "agressive" playing. The article implies that you can disable the head parking, but then I'd be worried about disk damage.
I wonder what the threshold is for head parking?

Just stick one on the ground and wait for earthquakes, who needs all that specialist equipment

I own a Thinkpad T41 which has this feature. One of the coolest things, to my friends, is that you can set the applet, which monitors harddrive shocks, to display the laptop in real time. It doesn't display vertical movement, however, it will show you flipping it upside-down, angling it in any direction, etc. It is pretty neat.
Finally! My Powerbook can be an etch-a-sketch. You could even get two of these for the knobs, if you're really into it...
This is the first piece of software that's had me drop my jaw for ages. Well done. I swear I will pay good money for the first "shake the machine and the window clears" etch-a-sketch plug-in for Pages or Keynote :)
Hmmm... differential GPS just depends on having a local waypoint to give you a very accurate position, beyond the 1-3 meter resolution of GPS.
:)
Now why not keep track of the accelerations, integrate (SUM) over time to get the velocity, integrate once again to get the spatial location. You could keep a log of where the laptop goes while it's on. Hmm... I might have to buy one of these toys, make the software and put it in the passenger seat of my car and see what I can make it do...
I remember a circuit cellar article about a 3-d accelerometer, but I didn't feel like dinking around with a soldering iron that year. Looks like a new powerbook will let me accomplish that long-delayed task with software alone.

Put a book under one leg of your desk?
If anybody is interested, I have recorded a video of the rotation of the two programs on the website.
You will notice that with the StableWindow, sometimes its a bit off, and with the AMSVisualizer, the Y-axis animations seem to be backwards. But, who cares? It's neat anyway.
