Title

How calibration is used in MirageXR

Learning in the real world is most effective when the activities are responsive to points of interest and events in the real world. MirageXR uses a single calibration marker to tie the digital augmentations to points of interest in the physical environment of the user. 

Where locations do not matter, the calibration marker can be hung somewhere where enough open space is provided to place the holograms. 

Where locations matter, like, for example, when instructing in a maker’s lab on how to handle a 3D printer, the activity will either include instruction on where to place the calibration marker directly or a hand-out will show students or teachers how to. 

Calibration is run simply by gazing at the calibration marker. An overlay animation will appear, with a circle completing segment by segment. A ‘click’ sound indicates when the calibration is concluded, and the overlay disappears. 

During calibration, all positions of task stations and their attached augmentations are repositioned relative to the marker center.

Orientation of the marker is not relevant, so it does not matter whether the marker is hung on a wall or lying on a table.
