1. A method comprising:
acquiring a first anchor pose of an anchoring device;
determining a first content pose, in relation to the first anchor pose, the first content pose being a pose of a piece of virtual content;
determining that a user device needs to determine a content pose of the piece of virtual content;
acquiring a pose uncertainty indicator;
determining a second content pose of the piece of virtual content; and
rendering the piece of virtual content using the second content pose, wherein
determining the second content pose of the piece of virtual content comprises:
i) determining the second content pose based on the first content pose and a second anchor pose in case the uncertainty indicator is less than a threshold value, or
ii) determining the second content pose based on visual features in case the uncertainty indicator is greater than the threshold value.
