This section assumes you know the hardware requirements and features of the Vive Hand Tracking SDK. Please read Vive Hand Tracking SDK Overview section before this section.

Vive Hand Tracking SDK provides an Unity3D plugin as a unity package. You can import the plugin in Unity3D from Assets -> Import Pacakge -> Custom Package… Menu. Samples are included in the plugin. Please refer to the test scenes in AristoSample folder for samples.

  • Minimum supported Unity3D version is 5.4, including all 5.5, 5.6, 2017 and 2018 series.
    • Plugin is tested on Unity3D 5.6.4p3 and 2017.4.16f1
    • Unity version 5.4 and 5.5 seriees are not tested, though the plugin should work
    • A Unity version that supports Android ARMv8 library is required if you what to use ARMv8 version of Vive Hand Tracking SDK
      • This means Unity 2018 series and Unity 2017.4.16f1 or later
      • ARMv8 version is preferred over ARMv7 version if possible

Based on different platform, process of setup may be different. Please refer to the sections below to setup each platform you use.



SteamVR disables camera by default. This means a fresh installed SteamVR cannot use Vive Hand Tracking SDK without manual setup. See Camera Setup in SteamVR for how to setup SteamVR and check camera availability before using Vive Hand Tracking SDK.

  • Make sure OpenVR is loaded as current VR before start detection.
    • Goto Player Settings and set VRSettings (5.x) or XRSettings (2017/2018) to include OpenVR.
  • SteamVR plugin is NOT required for the plugin to function.
  • The library DLL requires Microsoft Visual C++ Runtime 2015
  • Make sure to test camera frame rate in SteamVR settings before start application.


Starting from Unity 2018.2, Unity ships an OpenCL.dll in its installation, which might not work with some graphics drivers. If you encounter OpenCL error when running inside Unity editor, please consider upgrade your Unity to 2018.3.3f1 or newer, which seems to include fix for this related issue. Alternatively, you can remove the OpenCL.dll which is in the same folder with Unity.exe.

WaveVR (Vive Focus)

  • You need to import WaveVR SDK v2.0.37 or v2.1.8 into your Unity project
    • WaveVR 2.1.0 is not supported due to bugs in permission related codes.
  • Camera permission declaration and request are handled in the plugin using WaveVR API.
  • WaveVR only supports ARMv7 binaries.

Android Phones

  • The android library works for non-VR, Cardboard and Daydream.
  • The native library is tested on Pixel.
  • Camera permission declaration is included in plugin.
  • Camera permission runtime request is not included in the plugin. You need to make sure camera permission is granted before starting detection.
    • The only exception is for Daydream using GoogleVR plugin. The runtime permission request is included in the plugin.
  • Both ARMv7 and ARMv8 binaries are provided in Vive Hand Tracking SDK. The binaries are selected by Unity based on your actual archietecture setup in PlayerSetings.
  • The app must be in landscape left orientation.

Selecting Android Binary

Vive Hand Tracking SDK provides different binaries on Android for Android phones and WaveVR platform. This is due to using different APIs to get camera frames, which requires different native libraries.

Editor scripts in Aristo/Editor folder are used for easier Android binary selection. The scripts detect if WaveVR plugin is imported in your project to decide which binary is selected at build time. This should be enough for most use cases, unless you want to support both Android phones and WaveVR in the same Unity project.

You can manually control the process by modifying/removing the two scripts to suit your need. Required steps for each platform are listed below.


Only modify/remove editor scripts when you fully understand what you are doing.

  • If you need to build Android phone app:
    1. Remove Aristo/Plugins/Android/libs/armeabi-v7a/
    2. Remove ARISTO_WITH_WAVEVR from Script Define Symbols in Android player settings.
    3. If you are using Daydream with GoogleVR plugin, add ARISTO_WITH_GOOGLEVR to Script Define Symbols in Android player settings.
  • If you need to build WaveVR app:
    1. Remove Aristo/Plugins/Android/libs/armeabi-v7a/ and Aristo/Plugins/Android/libs/arm64-v8a/
    2. Add ARISTO_WITH_WAVEVR to Script Define Symbols in Android player settings.
    3. Remove ARISTO_WITH_GOOGLEVR from Script Define Symbols in Android player settings.
