Hi @zzy

1. Add joint rotation/pinch info/palm position info in result
   Can't see joint rotation in GestureResult
2. SetCameraTransform function
   Still missing in header

Hi @zzy

Yes, works fine right now.

But why in HMD space ? why no just in camera space ?

Hi @zzy

Do you call UseExternalTransform(true) before StartGestureDetection?

Yes.

Are  you applying hmd transform on GestureResult, making your hands move with your HMD.

Yes

Hi @zzy

I’ve got some problems.

If I put my physical hand on table ( in fixed pose ) and very slowly turn my headset up and down my virtual hand stays at the same position relative to virtual camera but if I turn my headset a bit faster ( not very fast ) my virtual hand moves with virtual camera and sometimes returns back to initial position in virtual world.

1.)    My frame rate is 90 fps

2.)    No joints, I use only origin of the first point.

3.)    Unity sample has no such issue

4.)    I tried to set maxFPS to 90 in GestureOption the results are the same

5.) The same test runs without issues if I replace Vive-wrapper with LM-wrapper. (both wrappers return only left hand position in headset system coordinates)

Any help would be appreciated.

@zzy when do you plan 'next release' ?

BTW it would be nice to add 'grab-strength' too...

[Win32 version]

Hi @zzy

Yes, it works now.

BTW Why don't make some helper function to calculate ( relative ) angles and pos for hand's bones ?

[typo in UE plugin]

ModelRenderer.cpp

Line 178:     float angle2 = UHandGestureUtils::UnsignedAngle(vec1p, forward);

Should be: float angle2 = UHandGestureUtils::UnsignedAngle(vec2p, forward);

Hi @zzy

GestureOption options;
const GestureFailure ret = StartGestureDetection( &options );

throws Access violation in aristo_interface.dll.

PS

1.) Camera test passed in SteamVR all drivers are up-to-date

2.) If i desable camera in SteanVR StartGestureDetection( &options ) returns GestureFailureCamera

3.) Vive Pro

Any help would be appreciated.

Hi @zzy

We currently using leapmotion in our products but not fully satisfied with it.
We would like to give a try to Vive hand Tracking but we can not migrate to x64 right now due to large code base.

Is there any chance to release x32 ?
