Hey, @SalaheddineSTA
There are multiple processes involved here:
- You want to know where exactly the real object is. There is an easy way to determine that, a mid-difficulty and a hard way. The easy way is to ask your user to identify the object. I recommend this approach. The mid-difficulty way is to supply your real object with some kind of marker and use a marker-tracking system like Vuforia to do the job for you. I recommend this approach in certain scenarios. The hard way is to analyze the highly lossy SpatialMapping and trying to recognize a pile of triangles as a car. I do not recommend this approach unless for some simple stuff like floors and walls (see SpatialUnderstanding from the HoloToolkit). Also you can combine all approaches in a very smart way, like markers for initial localization and human for re-calibration.
- Now that you know where the object is you can simply place your hologram there with gaze and gestures.
- Finally, if you wish to persist the location of your holograms during your app's runtime, between the launches or even across devices, you can use WorldAnchor, WorldAnchorStore and WorldAnchorTransferBatch accordingly.
Hope this helps.

The most common ways are:
- Using an image/qr code tracker. You can use vuforia or Microsoft's poster tracker (https://github.com/Microsoft/MixedRealityCompanionKit/tree/master/PosterCalibrationSample) to register key points in your room and setup your scene. Vuforia also has object/shape trackers but it would need to be a simple shape.
- Manually aligning the overlay. You could drag the hologram into the exact location you want before starting the project.
- If it is always going to be in the same room you could map the room and save the world anchors.
