Use this marker for each of the Insight Series apps.
Print the Insight Marker and place it on the floor in the space you are working.
Note that QR anchoring of your virtual scene operates differently in Insight apps (Insight Heart, Insight Lung, etc) than in the GigXR apps (HoloPatient, etc.) In Insight apps you will put the marker on the floor and look down at it with your HoloLens during the calibration step.
There is also a "tap to place" option which can be used with the Insight apps on HoloLens.
