This article demonstrates how to use the Vuforia HoloLens Sample project to author a Vuforia Engine scene for HoloLens and customize event handling to implement unique app behaviors. The sample project contains pre-configured Unity scenes and project settings that act as a starting point and reference for your own apps. It also demonstrates how to use Microsoft’s Mixed Reality Toolkit (MRTK) in Vuforia applications e.g. to work with hand gestures on the HoloLens 2. For additional background information on working with HoloLens, refer to the Developing Vuforia Apps for HoloLens article.
