iPhone users please help ;)

Hi,
Can iPhone users test if wakelock works on this VR game ?
Game is not finished yet, but seems wakelock is not reliable on iPhones (according to the client) and I don't have an iPhone to test.
I only have an iPad and wakelock doesn't work here.

Many thanx !

@jeromebg

I use iPhone X
I did not find any problems, it has been 5 minutes and the screen has not turned off

Thx for trying panoyun !
Strange, client still reports that wakelock doesn't work on first load with empty cache, and works as expected if he refresh the page...
Any clue on this ?
Thx !

Hi Jerome,

i did some more tests.
it is ugly..
the iPhone detects if there is 'attention'.
this 'attention' is not triggered by moving the device but actually looking at it( or touching it i suppose).
(my own conclusion) .. and it also says exactly that in the description of the 'automatic lock'.

So.. i would say.. cardboard and iphone is a worthless combination at the moment.
I tested this, again, a few times with this new insight.
When i visit your nice game.. visit a pano.. then put the iPhone away.. it goes to sleep/dim.. then turn the iphone on all axis .. nothing happens.. the dimm and lock continue..
When i do the same but hold it in my hand without touching the screen it stays good..
Face recognition/attention..

sorry.. i think this is bad news for all of us at the moment.

Hope there will be a fix..
Good christmas wishes from Holland!

Thanks a lot for testing Tuur, you're always a great help !
Hope Klaus could find a workaround, or this project might be dead before it started...

Ok, I bought an old iphone (6S) to test, IOS 14.3.
On first load (my tour or webvr example on krpano website) wakelock doesn't work, screen goes black, but on second load (you have to refresh the page) then wakelock works as expected...

Klaus any clue on how to solve this ?

jeromebg · January 4, 2021 at 9:17 AM

After more test it looks the problem is related to motion and orientation access authorisation ?
If it's the first time to activate webvr for a website safari ask if you want to enable motion and orientation access, in that case wakelock doesn't work on first load.
Once you enabled motion and orientation access for a domain then wakelock works for all webvr of that domain.
A workaround could be to refresh page when user enables motion and orientation access ? but is there an api for that ?

Hi,

I will have a look...

The wakelock hack works by playing a small hidden video and should prevent the Safari browser from letting the device sleep.

To start that video a touch anywhere is required and krpano will automatically wait and use any touch on the screen to do that.

The 'wakelock hack' starts when entering the VR mode, so maybe a touch on the screen is something missing...

I don't see a reason why the iOS gyro permission request should be involved here, but as written I will have a look.

Best regards,
Klaus

Thx for looking Klaus !
I also don't see why gyro permission has something to do with it, just what I noticed ?

jeromebg · January 5, 2021 at 5:41 PM

Did more test on Safari and Chrome with the same behaviour, and missing touch is not the problem.
With clean cache when you first enter webvr the orientation autorisation is prompted, I accept, gyro works but wakelock doesn't (even if I have touched the screen after entering Webvr mode).
If I reload the url or any url of the same domain then orientation autorisation is not asked anymore and wakelock works as expected.

PLEASE HELP !

THX !

jeromebg · January 6, 2021 at 11:48 AM

Ok, I found a workaround !
If I call DeviceMotionEvent.requestPermission before entering webvr mode then wakelock works as expected on first load !

Thanks!
Will check that.
