@THubbard I know it's been over a year, but did you find a great way to do this? I would love to know if you did. Best Regards, Louis

Hi @chengnay, Is there a way for me to store my video-files on the Standalone HTC Vive Focus 3 Headset, and the create a path to the videos in the .APK file. So when I run the Application from the headset, It locates the videos and play at a specific scene?

Yes I do. And i can also download it successfully. However, it does not show in my library. The problem was the size of the file. The app uses approximately 3 min of video (.mp4) in Ultra HD, which now is made HD instead. This creates an .APK file of approx. 1 GB instead of 2.93 GB and therefore pops up in the library on my Vive Focus 3 and works perfectly.

How this makes sense 🙂

One moment:

Here you go.

Hi @chengnay The .apk file is created from Unity and stored on the C-drive. I then use the "VIVE Business Streaming USB Cable" to transfer the .apk file to the headset. When i open the Command Prompt and type "adb devices", it just say: "'adb' is not recognized as an internal or external command, operable program or batch file."

I'm sorry, I don't know how to do that. Seems like a big task for a me (I don't have those type of computer skills)

I'm new to developing, so bear with me. I've downloaded the Android Logcat from Package Manager and tried to run it within Unity. I've copied everything i get into a text document which is attached: What should I do now? Logcat (before).txt

Working file around 1.01 GB, Not Working 2.93 GB

Unfortunately, the file ZIP-file is too big to be uploaded..

It is taking some time to create the ZIP file. I will upload once it is done

Hi @chengnay, Thank you for replying so fast, that is really great! Instead of building every scene, I have now tried building only a small part of my scenes. This WORKS (It now shows up in the Library), and that is the only change I have done. It has to be some capacity issue within the Focus 3.. Do you want me to send a zip-file of a Unity Project or the .APK file?

Yes, I just did, and unfortunately it didn't sort the problem.

Okay, I have not tried to uncheck the "Player Settings/Publishing Settings/Custom Main Manifest" from the large application, and the built the app. But it is still not showing up in the Focus 3 library when downloading to the headset. Any other approaches I could make?

Hi @chengnay, The smaller apps don't have any AndroidManifest file at "Assets/Plugins/Android". I just tried to add one to the small app from the Player Settings/Publishing Settings/Custom Main Manifest and then building the app. Now the small app will NOT show in the library (After a main AndroidManifest is created), that's weird...

I have built an Android Application in Unity which I want to transfer to the Standalone HTC Vive Focus 3 Headset. However, when I am trying to download the application on the headset, in says that the app is installed, but nothing is shown in the Library. I have been able to do it with smaller applications (around 400 MB), but this new app is 2,93 GB. Can that be a reason for it not showing up in the library? Best Regards, Louis H

I got it to work with the eyes being tracked, but now i want to actually collect data and use a video to collect data from. Any information on this?

In what way did you use the eye - and face tracker? Been trying to use the Eye tracking for gazing-data for investigating where participants are looking at a specific view-out but I don't know how to go on about it.

Hi @nreimens.ttt I am really interested in a more detailed description on how you get Eye Tracking data out from Unity when using the Focus 3! My main goal is to collect Eye Tracking data on a 360-degree video to get an understanding of where participants are looking at a specific view-out. I have been trying for hours and hours to get the Eye-Tracking working with Unity, but none of the tutorials regarding VIVE Wave or OpenXR works. iMotions and Tobii software are not working with the HTC VIVE Focus 3 . Best Regards, Louis H

When you're saying that you're running the eye tracker on the Focus3 over VBS, what does that mean? I've been trying for some time now to get any data out from the Focus 3 regarding the Eye Tracker, but I don't know how to go on about it...

Hi @DiegoVisionary I've been trying for about a week now to get the add-on Eye Tracker for HTC VIVE Focus 3 to work. First i wanted to use it on a project in Unity, but now I just want to try and get it to work on a 360-degree video/image and somehow get gazing data out of it. I spoke with Tobii support, but they said that they don't support the VIVE Focus 3. So did iMotions say.. Could you elaborate on what to do? I've tried to follow your link and download the SRanipalInstaller, but is says that can't open the "SRanipalService" as the file wasn't found.. TIA, Louis H

Thank you for the tip @MarcusN 🙂 Firstly: After creating an XR Rig and choosing an Android application when pressing "Build and Run" in the "Build Settings", it only supports "Head movement" and not Eye Tracking. Meaning I can only toggle the buttons when the middle of the HMD is focused on it. Not my eyes. Does it make sense and do you know what I need to do to fix it?

Hello, I would like to use the VIVE Focus 3 with the belonging "Eye Tracker", and I've been trying to implement the tracking into Unity. My main goal is to collect Gazing data on a 360-degree video to get an understanding of where participants are looking at a specific view-out, see figure of example: Reference Picture I have been trying for hours and hours to get the Eye-Tracking working with Unity, but none of the tutorials regarding VIVE Wave or OpenXR works. Do any of you have any recommendations or step-by-step videos/pictures that could help me out? This is the first time using Unity, so it is quite a task. Best Regards, Louis H
