4C Head tracking data in Unity SDK

[Alex [Tobii]]

Hi! We are working on it.

Currently the only public way to get head pose data is through the new low level API:
https://www.nuget.org/packages/Tobii.StreamEngine.Native/
https://www.nuget.org/packages/Tobii.StreamEngine/

This is a low level API so please only use it if you know why you are doing it. Very little support is going to be provided.

Thank you for the post Mr. Alex. At present my laptop is not working properly to check this functionality. Meanwhile I would like to know , whether it provides only two angle values from eyes focusing points on the screen (or) Head Position (X, Y , Z) and rotation (pitch, yaw and roll).

Thanking you
Best Regards,
Anil

Hi!

It’s x, y, z, yaw, pitch, roll.

It’s important to say that Tobii Eye Tracker 4C is primarily an eye tracker, so head pose signal should be considered as an add-on feature and its quality may vary. We strongly recommend using it in combination with eye tracking for features like Extended View.

Could you please tell me , how long does it take to release the head pose signal SDK.

Hi!

What do you mean by the head pose signal SDK? Adding it to Unity SDK? It’s almost there, but we still need some time before we can release it publicly. Unfortunately I can’t say any dates.

I saw you had mentioned sending out a beta package. Would it be possible for me to get a beta package of the Unity SDK with head tracking? I’m trying out a variety of eye / head tracking platforms, and I’m hoping to determine if Tobii is the solution for our company to go with soon. I’m only planning to make demos and prototypes, so I’m fine if the package is still buggy.

I totally understand if you do not want to send a beta package.

Hi @alex

I would really appreciate if you could send me the beta package mentioned in previous posts please 🙂

Hi!

It’s published now. You can download it here:

Hi is there an update for c# SDK as well?

[Alex [Tobii]]

Yes.

For general C# (not Unity):

Nuget package:
https://www.nuget.org/packages/Tobii.Interaction/

Hi,
I got a Tobii EyeX tracker 4C and I use C++. Is there a way to access head tracking data using the SDK? Any help will be much appreciated!
Best regards,

Hi!

It’s definitely possible our low level Stream Engine API:

Nuget package:
https://www.nuget.org/packages/Tobii.StreamEngine.Native/

Documentation & samples:
https://github.com/Tobii/stream_engine

Hi Alex,
Thanks a lot. Just another query, in the SDK guide link in the Tobii website it says that the higher level Interaction API of the Core SDK for C/C++ will be released soon. Can you please give me an idea when it will be released?

Thanks,
Ann

Hi!

I don’t have exact information, but I believe it’s months away.

What is your application about? Is it a game?

[Anuradha Kar]

Hi Alex,
My application just needs real time head pose data of users looking at videos. I will work with the stream engine, I just thought that the higher level API will be easier to work with (as I am a c++ beginner). Is there any sample c++ code that extracts the head pose information from the 4c tracker? Any help on this would be great!

Best regards,
Ann
