Just sharing a project done with Vuforia to read a card and generate Augmented Reality Characters with music.
Testing and Real-World Use
This could be tested by repeatedly losing and reacquiring a printed target while checking that animation and audio start, pause and resume consistently. The event-handling pattern is useful for interactive exhibits and learning cards, without treating the demonstration as a benchmark of tracking accuracy.
