Notes for Windows

  • Gesture detection uses OpenCL for GPU acceleration. Please make sure you have installed latest driver for your graphics card.
    • This includes driver for your Intel iGPU, since NVIDIA driver sometimes does not install OpenCL correctly.
    • A quick check is to make sure C:Windowssystem32OpenCL.dll exists and is valid.
  • 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.
    • This need to be done on PCs of developers and end users.
  • It might take more than half a minute for internal setup on each machine, if Gesture is run for the first time. The setup is only needed once and subsequent launches should start very quickly.

Notes for Android

  • CPU backend is recommended on Android devices to leave entire GPU for VR rendering tasks.
  • Different binaries are provided for Android phones and HTC Vive Focus, due to different ways to fetch camera frames, i.e. NDK Camera2 API vs. WaveVR_Camera API.
  • ARMv8 version is preferred over ARMv7 version, for better detection speed and enery efficiency.
  • The app must be in landscape left orientation.
