Hello everyone, I'm developer of Vive Hand Tracking SDK. This topic will include some suggestions and requirements for using Hand Tracking SDK.
This FAQ is intended for latest version (v0.8.1). If you are using older version, please upgrade to v0.8.1 first.
To run inside Unity Editor, please make sure:
Start Detection Error: Camera
Hand tracking SDK uses camera frames to detect hands, so make sure you have correct setup for camera device:
Start Detection Error: OpenCL
Hand tracking SDK on Windows requires OpenCL for GPU acceleration, therefore please make sure you have proper drivers installed:
Bad hand detection accuracy
Hand Tracking SDK uses a deep learning model to detection hands and fingers. So the accuracy depends largely on the training images, and we are consistently collecting data and improving accuracy. Therefore, hand detection, especially finger tracking, may vary based on your lighting condition and background. Here are some tips for temporarily improve accuracy:

1. Are you using 32-bit Unity? We only support 64-bit Unity Editor on 64-bit Windows.
2. Please check if Assets/Aristo/Plugins/x86_64/aristo_interface.dll exists.

Hello! Thank you for this post. But unfortunately, when I start the game in the "Sample" scene, I get the following error:
"Start gesture detection failed: Camera
What can be wrong?

Please follow instructions in our document to setup camera on SteamVR: https://developer.viveport.com/documents/sdk/en/misc/steamvr.html

Could you tell me when the Vive Hand Tracking plugin will be available for Unreal Engine? I mean for Vive Focus (Android).

Hi @MDV Games, we are currently working on it. We plan to release it in Q2.
Since no one in our team is familiar with Unreal, it may take some time.

I tried to run the given sample scene. OpenVR was included, the camera was working fine, already update patch
However, when ran using Unity 2018.2.20, Unity showed error
when ran using Unity 2017.4.16, Unity crashed and disappeared
The problem also occured when include GestureProvider script to other scenes
Do you know what might be the problem of this

Please help to provide more information about your problem, so we can identify the reason:
1. Can you show what's error you encountered in Unity 2018.2.20?
2. On Unity 2017.4.16, if it crashes after play, you can open Visual Studio, attach to Unity.exe and see where it crashes. See this link for instructions

From a quick google about "igdrclneo64.dll", it seems to be a driver problem which makes OpenCL failed to work. Please make sure:
1. You have installed latest drivers from NVIDIA/AMD (depending on your vendor) and Intel (seems your Intel CPU have integrated GPU). Don't use the one installed by Windows Update. Goto the company website and go to support/driver download page to download latest drivers.
2. Your Vive/Vive Pro is not connected to Intel iGPU.
3. If you still encounter this failure, I would recommend you to disable iGPU in your bios.
Besides, you can test if OpenCL is successfully installed on your system. You can download a OpenCL device query binary from NVIDIA opencl sample website. Scroll down the page and download "OpenCL Device Query" for Windows (x64). You can use the binary in the "NVIDIA GPU Computing SDK\OpenCL\bin\win64\Release" folder of the zip file.
Finally, if this does not solve your problem, I would recommend you to start a new topic dedicated for your problem and we can continue discussion there.
