The WEKIT Deliverable 4.5 “AR-visualization System and AR-based Experience Re- enactment and Learning System” is report of WEKIT Re-enactment (AR-Player) demonstrator/prototype. This deliverable is combined version of deliverables D4.1 “AR-visualization System” and D4.3 “AR-based Experience Re-enactment and Learning System” as these two components cannot separate in demonstrator.
Deliverable 4.5 “AR-visualization System and AR-based Experience Re-enactment and Learning System” describes main features of WEKIT Player which is following the main principles of the IEEE Draft Standard for an Augmented Reality Learning Experience Mode (ARLEM).
Section 1 describes overall architecture of the WEKIT Re-enactment prototype. The architecture includes Microsoft HoloLens side the sensor and tracking environment, GUI and back-end. Also, in the architecture can be found connection to local and cloud-based data repository.
The next Section 2, provides overview to process for developing Presentation layer and detailed description of implemented solution. Presentation layer was updated based on feedback from trials. Updated were done in small steps within three laboratory tests. Laboratory tests were following the main principles of Human Centred Design. Altogether 16 persons (7 male, 9 female) participated in the tests. Between the tests the WEKIT Player was updated based on user feedback and requirements before the final implementations.
Section 3 describes the application layer, which has been described in sub-sections. Workplace and activity manager are parsing information from ARLEM based Activity and Workplace JSONs. Sensor interface, in our case MQTT allows WEKIT Player to get information from user and environment. And processing part, where WEKIT Players system logic exits.
The following section 4, gives summary of the Data layer. From WEKIT player point of view data layer includes all ARLEM based information for work support and training.
Last sections 5 provides an overall conclusion of AR-visualization System and AR-based Experience Re-enactment and Learning System.
