¿µ¹®³»¿ë¿ä¾à This standard proposes the 5W1H-based metadata schema that supports expandability and context-aware feature for AR visualization, and suggests acutal details of the metadata. Finally, as a case of application, augmented reality standard model is presented that supports generality and context-aware feature to provide personalized experience to the users.
The 5W1H-based metadata schema is constructed as PoI-AR Anchor-AR contents relation that reflects the characteristic of AR that is mixture of the real and virtual world. Moreover, 5W1H representation supports the feature of the intuitional context-awareness and expandability. Based on the 5W1H-based metadata schema, details of the actual metadata structure are established according to the feature of the module. Therefore, the metadata structures consists of the PoI, AR Anchor, and AR Contents class and lower classes of them such as recognition data for PoI, specific types(video, sound, image and so on) for AR contents are also designed.
For this standard, cultural heritage domain is selected for deploying implementation. However, these metadata are devised to be independent with certain domains. Proposed the AR reference model is devised for context-aware AR service in cultural heritage domain, and the model is composed of user, real world, and whole structure for augmented reality system, and contains compositions related to context-aware service.
