Hi Carsten,

We will try to reproduce the issue in more diverse environments.
The information is critical.

Thank you.

 

[Delay on "Dual Camera"]

Hi MacBread,
Yes, We intended.
The positions of "Dual Camera" and "Render Camera" are at different time steps for making the experience more real.
Thank you.

[SRWorks SDK Release 0.9.3.0 Crash on Unreal Engine 4.25]

Hi Eyad,

I am sorry for the inconvenience.

In the version 0.9.3.0, the project SRWorks (XR) SDK UE4 Samples doesn't support Unreal Engine 4.24 but the project SRWorks (XR) SDK UE4 Plugin have supported it.

Are your project based on  SRWorks (XR) SDK UE4 Samples?

Thank you.

Also, when I try to run the C sample, the following call returns a failure (code -1).

ViveSR_InitialModule(ID_PASSTHROUGH);

All cleanup calls afterwards return error 1021 (INVALID_CHANGE). I am on the latest SRWorks 0.9.3.0 version. My SteamVR version is 1.12.5. 

Also the normal system see-through of the HMD is working (i.e. when I double-tab the system button on the controller). The cameras aren't broken - it must be some sort of communication error.

Hi cru89,

Would you please attach your log again after running the C sample?
I cannot fetch a piece of information from the log you attached because everything seems fine.
Thank you

Would you please attach your log file via the forum?

Thank you

 

[About GazeRayParameter sensitive_factor]

Hi Nitesh,

Yes, you are right.

It is just a filter and you can adjust the variable to effect the cutoff slope in the filter.

The default value is 0.007 and you can multiply or divide the variable by 10 until you notice the effect on the gaze data.

Thank you,

[[SRWorks C lib 0.9.0.3] ViveSR_GetVersion() seems returning wrong value "0.0.0.1"]

Hi ayumu_naga,

Thank you.

It has been fixed in latest version.

 

[SDK C Samples (9.0.3) not displaying any images from cameras]

Hi Alexis,

I am sorry for omitting in sample code.

It should add an instruction for copy data from GPU.

You can resolve this problem by calling

ViveSR_SetParameterBool( ID_PASSTHROUGH, ViveSR::PassThrough::Param::DISTORT_GPU_TO_CPU_ENABLE, true);

after

ViveSR_InitialModule(ID_PASSTHROUGH);

We are going to fix this issue in next version.

Thank you for reporting the issue.

[How are the data of time stamp and frame measured?]

Hi @imarin18,

In order confirm your state, could you please provide more information?

For example, your computer equipment, the meaning of x axis in your chart and how you get the timestamp in source code.

Thank you.

Thank WenJie,

So if I'm interested in the verbose data from eyedata_v2, I shouldn't be worrying about filtering? Is it safe to just disable it nonetheless.

Thank you

Hi Marcellotham,

Yes, filtering works as previous version.

Thanks,

WenJie

[Pro eye unsuitable for research - data SUPER heavily filtered during fixation.]

Hi Marcellotham,

SetEyeParameter() is still supported in Eyedata_v2 but filtering always only works on gaze rays. 

So the versions of data doesn't effect filtering.

Thanks,

WenJie

[Eye tracking data - Filter]

Hi André @AKCH,

Gaze origin and Gaze direction are processed if the GazeRayParameter: sensitive_factor has been adjusted.

Pupil position is the raw data.

[Does SRanipal_Eye.SetEyeParameter work?]

Hi Scott,

I recommend you can start with values like 0.001 or 0.0001 and multiply and divide this parameter by 10.

 

[A couple of questions about Focus() and Accuracy]

This satiation might be that you've put too many colliders into the sense.
There is a method to resolve it.
Actually, you can found out that the method Focus() wraps the unity API Physic.Raycast().

Acording to documant of unity 3d user manual, you can ignore colliders with layer mask when casting a ray.

Hence, you can manually create a layer and cast a ray only against the layer and ignore all other colliders.

Thank you.
