Problem with some mobile phones only scrolling up-down (krpano)

[MATRADI]

I use krpano version 1.19-pr13 to produce 3D stereoscopic panoramas of interiors (CG, not real photos).

 

Everything works fine in my computer and my mobile, but this morning I was doing a demonstration for a client and two of their mobile phones didn’t work right: As they move them in every direction, the pano only scrolls up and down, not sideways.

 

These were Samsung mobiles with Android OS and Google Chrome.

Ok.

 

Klaus, the author of krpano, solved my question. I copy here the answer in case it helps others:

Hi:

 

When this is happening, then the Android device doesn't have a gyroscope sensor! Normally this are only cheap low-end Android phones...

 

The up/down panning and left/right rolling will be done roughly by the acceleration sensors. But for the left/right panning and the fine movements a gyroscope sensor is required. Without gyroscope this is technically not possible.

 

You should have the same problem also in all other apps that are using the gyroscope on that device.

 

From JS/krpano side itself is unfortunately not possible to detect that case. Normally it should be the Chrome browser itself that should report that there is no gyroscope, but sometimes it doesn't do that (could be maybe also related to the device itself).

 

Best regards,

Klaus
