For those interested, the Haro3D library version 2.0 that includes a LabVIEW API for the Microsoft Hololens is now available. The library can be downloaded using VIPM.
Notice that if you you have a license of version 1, installing version 2.0 might mess up your license. Additionally, if you already had the 30-day trial for version 1, the trial will not be available for version 2 if you install it on the same computer.
Also notice that the API requires the Haro3D app to be running on the Hololens (or emulator).
Below are two videos showing how to use the Haro3D library to control the Hololens using LabVIEW.
