i compiled and deployed the Hololens Vuforia example.
The marker as suggested has extended tracking on.
Unfortunately it does not register smaller marker movements, therefore making it really difficult to use it for fine alignment.
Notice though that because of extended tracking the object can persist even after the marker is removed.
Can we fine tune somehow the extended tracking to perceive also these small movements?
Can there be a metric to switch extended tracking on off for small movement calibration?
Here is a video which shows what I am saying.
