I am currently trying to retrieve eyetracker data in a Unity application using C#. Could you please explain how you managed to collect pupil diameter data in Unity? Which SDK did you use? Any information would be highly valuable to me! Thank you very much in advance. Best regards, Cice

sorry in the path missing a "/". This is the correct path to access the local storage of the Unity build: "/mnt/sdcard/Android/data/com.DefaultCompany.projectname/files"

Thank you @JAMESJ, I found a solution that worked for me. For anyone interested, I used the following path: "/mnt/sdcard/Android/datacom.DefaultCompany.projectname/files" Additionally, I modified the Android Manifest under --> Player Settings --> Player --> Publishing Settings --> Custom Main Manifest At that point, I found it in Assets\Plugins\Android\AndroidManifest.xml and modified it as follows to include permissions: <?xml version="1.0" encoding="utf-8"?> <manifest xmlns:android="http://schemas.android.com/apk/res/android" package="com.unity3d.player" xmlns:tools="http://schemas.android.com/tools"> <application android:icon="@drawable/app_icon" android:label="@string/app_name" android:theme="@style/Theme.WaveVR.Black" android:resizeableActivity="false" tools:replace="android:theme"> <!--You can use your theme here.--> <activity android:name="com.htc.vr.unity.WVRUnityVRActivity" android:label="@string/app_name" android:configChanges="density|fontScale|keyboard|keyboardHidden|layoutDirection|locale|mnc|mcc|navigation|orientation|screenLayout|screenSize|smallestScreenSize|uiMode|touchscreen" android:enableVrMode="@string/wvr_vr_mode_component"> <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> <category android:name="com.htc.intent.category.VRAPP" /> </intent-filter> <meta-data android:name="unityplayer.UnityActivity" android:value="true"/> </activity> </application> <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /> <uses-permission android:name="vive.wave.vr.oem.data.OEMDataRead" /> <uses-permission android:name="vive.wave.vr.oem.data.OEMDataWrite" /> <!-- <uses-permission android:name="android.permission.CAMERA" /> --> <!-- <uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /> --> </manifest> I hope this helps!

Hi @Alex_HTC and hi everyone, I have the same issue. I would like to access local files on HTC Vive Focus 3 as I am working with large video files through a Unity apk. I need to access the project build folder or a local folder on the HTC Vive Focus 3 device. When I was working on Meta Quest 2, I used the following path: /sdcard/Android/data/com.DefaultCompany.projectname/video. Do you have any advice on how to access these folders on HTC Vive Focus 3? Thanks a lot in advance

I have been trying to work with HTC Focus 3 in Unity for a few weeks, and I would like to implement eye tracking data collection. There is very little information available online about this. I found this discussion, and I want to inform you that I have the same issue with Unity 2021.3.7f1. I am attempting to visualize the output data from my Eye Tracker Focus 3 in Unity using the VIVE Wave XR Plugin - Essence SDK (Version 5.3.1-r.2). I am using the EyeManager from the Wave SDK. Unity is logging the following output to the console: "Wave.Essence.Eye.EyeManager StartEyeTrackingLock() result: WVR_Error_FeatureNotSupport, status: UNSUPPORT" "Wave.Essence.Eye.EyeManager Update() m_LocationSpace: World, hasEyeTrackingData: FalseUpdate() m_CombinedEyeOriginValid: False, m_CombinedEyeOrigin (0, 0, 0), m_CombinedEyeDirectionValid: False, m_CombinedEyeDirection (0, 0, 0)Update() m_LeftEyeOriginValid: False, m_LeftEyeOrigin (0, 0, 0), m_LeftEyeDirectionValid: False, m_LeftEyeDirection (0, 0, 0)Update() m_RightEyeOriginValid: False, m_RightEyeOrigin (0, 0, 0), m_RightEyeDirectionValid: False, m_RightEyeDirection (0, 0, 0)" How can I avoid this problem? Is there a sample project to test the Wave SDK eye tracker? Thanks to anyone who can provide an answer or update on this.
