Using Device Tracking with Object Targets
The Device Tracker improves tracking robustness by using features of the environment surrounding the target. It enables you to use smaller targets and allows for tracking targets farther away from the camera. It additionally, enables Extended Tracking where your target can be tracked even when the Object Target is no longer in the camera view.
NOTE: That Object Targets work best with Device Tracking when the object is stationary during the user experience.

Using Multiple Object Targets Simultaneously
For your specific scenarios and better use cases, Vuforia offers simultaneous tracking of targets and different target types. You can also manage the number of tracked targets to limit the performance strain on the devices. Let up to two Object Targets be tracked simultaneously in your scenario and go even further and combine and track other Vuforia target types alongside them for eye-catching experiences.
Visit Detect and Track Multiple Targets Simultaneously for more information.
Object Target API Overview
The ObjectTarget is tracked by the ObjectTracker. The corresponding TrackableResult (in this case an ObjectTargetResult) returns the tracking data of the Object Target.
Please, refer to the ObjectTracker API Overview for more information.
Immerse your users with occluding your digital content behind and underneath your Object Target. Use either a bounding box or a detailed digital model of your object to create a masking effect on your Object Target.
Follow the guide How to Use the Occlusion Model in Unity.
