[Q] Gyroscopic camera

Or gyro stabilized camera.
My train of thought might be too naive; (phone has gyroscope, phone has camera, why not!) but really is it something possible to give to our DHDs? A videocamera with which no matter how the phone was rotated, the horizon in the recorded video will always stay horizontal. They got used in MotoGP.
Here's a video example for anyone unfamiliar with them - skip to 40seconds in
motogp.com/en/videos/2010/Rossi+debuts+Gyroscopic+OnBoard+camera

Anyone got any idea? Or maybe I should actuallt ask in general android apps.

It wouldnt be impossible but it would take quite a lot of processing power and would take a lot of time to make. And I'm not sure if anybody has that sort of time.

You sure the phone has a gyroscope? Your not confusing it with the accelerometer are you?

And that isn't the correct way to build it either.

Oh ok, thanks a lot. That provided some food for Googling on these things.
Silly marketing got me again; so a g-sensor is actually an accelerometer which is different from a gyroscope and not as accurate at measuring movement (tilt/pitch in specific). DHD has accelerometer only while iPhone 4 and upcoming Sensation are also equipped with a gyroscope (or gyro-sensor).

[Q] how to fix the sensors after flashing andriod

hi
how are you all
please help me fixing my phone sensors it was good but after flashing android the left sensor still good but the right sensor stop working (i am on bada 2.0)

yeah i have same ur problem
we want a sloution

I read the forum. I'm on Android. I don't know the Bada system but if the operating system does the same thing, then you may have somewhere, the option to calibrate the sensors in the settings option. Any more than this, I would opt to go back to your original os, until you've found out where to go on this forum.

How did you notice that? Maybe it's a bada 2.0 Bug...
Did you tried to flash Android on Bada 2?
Did you removed Android before flashing bada 2.0?

That is Android's fault and mainly user's fault also
Devs stated that sensors doesn't work in Android though you find people trying to calibrate them
WTH is the user doing by calibrating the sensors in Android ????
bada sensors calibration is screwed up
for motion sensor calibration try to put your phone on a horizontal floor and calibrate it with this code *#66225*#
for other sensors i don't know what you should do
Best Regards

Sensor Calibration

Hey,
can anyone tell me how to calibrate the G-Sensor in the Gaaxy Nexus Prime? In games and apps using this sensor it seems that the y-axis is about 5 degrees leftside when i hold the smartphone straight up. This means for example that the figure in doodle jump moves slowly left, although the Nexus is holded erect...
Googled for an solution by myself, but nothing helped so far. Even apps like BubbleLevel, which have the calibration tool, calibrate the sensor just for this app... and not in general.
Thanks

Try calibrating with this app and see if it helps.

Ignore everyone telling you to use an app to do it, because you can't. Android has no concept of global calibration regarding the sensors.
I have 3 Android phones, they all have wrong default calibration, from a few degrees (Galaxy Nexus) to about 30 degrees (Xperia X10 Mini Pro.. unusable).

You used to be able to calibrate in gingerbread by modding axis offset values in the AK8973Prms.txt file in data/misc. ICS doesn't seen to have that file, at least not in the same place.

HTC Desire, Desire HD have its calibration app.

He asked for help and I tried to help him with what work for me in the past. No need to tell him to ignore people. It's a simple process that involves rotating the phone on 3 of its axis. If it helps, then great. But it certainly wouldn't hurt for him to try, would it? No need to be condescending; it's not like I'm trying cause him harm.

I think that method works well for compass calibration for apps like maps and sky, but it is temporary and doesn't seem to affect pitch and roll. GPS status let's you calibrate pitch and roll but only within the app, it doesn't affect system calibration. The file i mentioned above did allow manual system calibration under gingerbread. Not sure how to accomplish under ics. A post i saw suggested that gnex and ics automatically calibrate if you leave the unit to sit alone for a bit. I don't buy it, but that's the only info i have found.
In case anyone is interested in how it was done under gingerbread, see my post at http://forum.xda-developers.com/showthread.php?p=16592139

It's not Gingerbread, it's for that specific sensor with that specific driver. The Galaxy Nexus uses a Bosch BMA250 which has an NV memory where calibration settings can be stored but doing so is not trivial.

[Q] Note 2 : Street view jitter in compass mode ?

Hi
I bought the Note II 2 days ago, and I ended trying Google Street View in compass mode... Nice software...
As probably you know, in this mode the orientation of the handset controls what you see on the screen, offering a better 3d experience than simply sliding your finger on the screen to change the viewpoint (try it: maps --> select a place with street view available --> enter street view mode --> press "menu" left virtual touch --> select compass mode, and play with it!).
This is all nice and well, except that I experience on my phone a serious random jitter (mostly azymuthal) in the street view: a few degrees more or less, not much but enough to make you dizzy after a while. This happens also in Google Skymap.
I tried to recalibrate the gyroscope, also had a look in the hidden "test" menu (dialed *#0*#), and installed marketplace compass apps which offer calibration tools... to no avail. I also changed position in my flat to check for stray magnetic fields effects, but nothing new.
I know there are other devices forum threads where this type of problems is explored (not much as far as i know), the point here is I would like people with Note 2 at hand to check if they experience the same type of problems: I'd like to know if this could be related to a hardware problem, or if it is another screw up by Google/Samsung ...! :silly:
What do you think ?

Same thing here, I've had my T-Mobile GNote2 for just under two weeks and when I tried the compass this am I found the same jitter you describe, using GPS Test app and the diagnostic mode you found. Started a thread in T-Mobile GNote2 here, looks like it wasn't a priority for Samsung.

I'm getting gitter in Street View too. Damn annoying.

Bad jitter here too .... and this was one of the features that seemed best to try out on the larger screen... Hopefully there will be a software fix. If some people would post that they have no jitter in street view compass mode, then I'd go see if it was just my/some units with the defect and exchange while in my 14 days.

I can confirm the jittering on my Note 2. It's pretty annoying. Calibration hasn't worked for me.

In other compass apps, I can't experience any jittering. So I think it must be directly related to Street View and how they read/process the values from the compass. Maybe the interpolation is wrong?

Well, I can tell you that I exchanged TWICE my Note II since I posted the problem on the forum (one was exchanged for another reason)... and the jitter was and is here on the three handsets.
The last one I got works marginally better, but the effect is still quite annoying.

I tried a few compass apps. They mostly had the jitter as well... and the *# test menu showed the same jitter back and forth on the compass :=/

Are you all running on stock rom and kernel? So maybe we can isolate the source for the jittering.

Jittery here too... On stock rom/kernal

Hm, stock rom/kernel...why doesn't Samsung test this stuff before releasing. Now we need to find out, if it's a software failure or a hardware problem. I have tested this compass app and there is no jittering. Can anyone confirm this?

I have slight jitter in compass mode on street view too.
Stock ROM, no root.

I've tried several other stock/non-stock roms and kernels. All have the same problem. Has anyone contacted Samsung about this?

That's exactly what I'm saying! I actually called Samsung's main technical services department and the person I spoke to didn't have a clue what I was on about, so I had to describe it to her carefully. And by the way, yes I've tried it on all the available compass apps on the play store and they all have the same issue. To compare, I used my dad's S3, totally fine. This is one of the reasons I bought the phone in the first place, to use the street view in compass mode after seeing it on the S3 but its a total letdown, which leads me to believe that its very likely a hardware issue, and that's what I'm dreading.

Maybe it also could be a software problem. I don't think that Samsung includes defect hardware sensors in all of their Note 2 devices (therefor they have extensive hardware tests). I hardly believe they hadn't had the time to write a proper kernel driver with interpolation for the magnetometer. And probably all other kernels base on the kernel sources, Samsung has published. So this could be an inherited problem. Would be interesting if the Note 2 and the S3 share the same magnetometer sensor. Can somebody elaborate on this? If so, then we need to compare the kernel sources for both sensors and try do debug the problem step by step.

So you're telling me this problem may be fixed with either a 4.2 or 5.0 update? One can only wish right now.

Jitter here too. Very annoying. Quite shocked this got past QC.
Tried multiple roms and kennels, always the same.

Well I'm now on stock 4.1.2, and sad to say its the same problem. Absolutely nothing has changed. I think we're stuck with this issue guys, such a shame

it is a big samsung problem. it is on the S3 as well...

I had the same problem. I tried several compass applications from the market and celebrated the compass several times. The only thing that really helped to get the digital compass get stable is to turn off all wireless functions, including the phone, as well as the phone sound and power saving functions. I turned off anything that might produce a megnatic field in the phone, and then calebrated the compass again. Now the compass works fine after turning on everything.

The compass works on my phone fine. Please if someone can at least install the app to check operation. Thanks a bunch.

All these views and not one piece of advice? Really? 34 people up to this point.......35 for who is reading this now......
And no one cares about a non functioning compass? Ahhhh

The Huawei Watch doesn't have a compass, so it won't work.
