Android hand tracking - starting tips ?

Recommended Posts

Thats probably not the case as I have both the controller and daydream view on my desk, but I've noticed the following problem in adb log :

It seems that the android ndk is failing to update camera, I dont have NDK installed but will try with it next, do I have to change from mono to il2cpp ?

Hi  

 

You are right, the problem is in Hand Tracking SDK now, since we cannot get camera frames from your rear camera. From the log, we can find a rear camera, but cannot get frames from it.

 

If you are building 32bit binary, using mono is definitely fine.

 

Please make sure:

1. Your app have camera permission (I recommend you grant permission manually in Settings)

2. Some phones may not support NDK Camera2 API, which is what we use to get frames. A simple check is to try this example and see if it works.

Allright, the example Native Android Camera2 shows black, is there any option to enable it or change the api from camera2 to other camera provider?
edit:


After a while it seems that native android camera actually does work, so that makes me wonder what doesnt work on the aristo side.

OK, it seems that on your phone, it takes a longer time before the camera streaming starts to output frames. We internally have a 1.5 second timeout for waiting one frame. This seems to be the reason. I'll try to increase the timeout for the first frame in next version (expected to release in a few days).

Hi , yes the next version includes Android phone and Focus support in Unreal plugin

Hey,
I've tried the update and there is a progress - it actually started!
I can see the green and blue balls flying where my hand should be, thats unbeliveable.

And it recognizes gestures too! for now only pointing fist and all five works, "ok" gesture didnt trigger nothing yet.

Phone gets hot pretty quick.

And it seem to lose track of hand centre and jump to fingers but thats ok.

Sometimes hand tracking stops and doesnt want to start but after app forced close it worked again, 

Implying that Aristo service runs after app was closed or stays in memory.

Anyway im pretty excited for this technology to mature and ways I could use it!

 

Dropping logcat for good measure:
