- Continuously process frames captured by the HoloLens color camera and attach the tags returned by Microsoft's Cognitive Service Vision API
But first, let's set up the environment and then look at how we can better understand the environment by plotting paths where the user walks using spatial anchors (via SpatialAnchor). Start by launching the starter solution for this chapter; this can be found in the directory Chapter3/Starter from the repository https://github.com/PacktPublishing/Microsoft-HoloLens-By-Example. Launch the Visual Studio solution by either double-clicking on the solution file AssistantItemFinder.sln or by loading from within Visual Studio by navigating via File | Open | Project | Solution and selecting the AssistantItemFinder.sln file. The starter solution is more or less the standard Visual C# holographic...
