Iphone compass app
I have read that the Iphone uses a magnetic compass, which suggests it
would be affected by very local magnetic fields, but putting a magnet close to my SE doesn't seem to affect it at all. What am I missing? |

What am I missing? It's magic [tm] It's probably doing an AI job on you, and possibly cancelling out your deliberate field interference when compared with other sources (GPS, skyhook) of information - which probably has a few vectors valid within a time window. Should be able to fool it though. Keep trying, say - turn off the wireless comms? or sweeping your magnet across slowly. -- Adrian C |

I don't know but I do find often that moving in the garden seems to effect
its detection of north, so I'm guessing its actually quite slow at detecting things. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff...

Its an older but much loved Iphone model as it actually has a real earphone
socket on it. Brian -- ----- -- This newsgroup posting comes to you directly from... The Sofa of Brian Gaff... Blind user, so no pictures please Note this Signature is meaningless.!

It happens that Brian Gaff formulated :
I don't know but I do find often that moving in the garden seems to effect its detection of north, so I'm guessing its actually quite slow at detecting things. Brian That makes some sense. I guess it is using a mix of magnetic and gyro/ motion sensor, to work out a bearing, which is causing a lag in response to a magnet. The thing is, it keeps showing upto 90 deg out on a bearing on the compass. I do have a magnet close to where I charge it, one I was using to check its response to a magnet. So long term it uses magnetic field, short term it uses its gyro. |

. What am I missing? The inputs from the accelerometers. If the phone isn't moving there's no point updating the compass. |
