Diverse augmented reality exhibitions for differential users based upon private quick response code

The marker-based augmented reality (AR) system can produce 3D virtual object to satisfy the user interaction in the real-world. The marker is a tag/pattern and used to help the AR system to locate the corresponding virtual object on the scene. The marker, however, needs to be designed firstly and the recognition capability is limited. The exhibited virtual object and the marker, unfortunately, are linked in the AR system. Hence, such conventional AR system treats all users as the same role. In this article, we proposed a diversity AR system that can provide the differential virtual objects exhibitions for specific users, such as the joint member and different degree person. The new schemes exploited the error correction capability of QR barcode to conceal the individual secret stream of users into a QR marker. Consequently, the general user can only observe the normal 3D virtual object on the marked QR tag. The assigned members can further reveal the various virtual objects from the same QR tag. The proposed diverse AR system can distinguish different users from same QR marker and thereby exhibit the corresponding virtual objects. The new system is practical and can be widely applied in specific customer AR applications.
