Figure 4. Visual Representation of the Industrial AR solution
JSON Configuration Storage: Each machine-role UI configuration is encapsulated as a JSON file. These files are dynamically generated based on user preferences and are centrally stored on the Unity server, ensuring data consistency and easy accessibility.
AR Client Interface: The AR glasses operate as clients, pulling the latest UI configurations based on the detected machine and the pre-configured user role. These glasses utilize the Snapdragon Spaces framework, facilitating accurate machine recognition, seamless hand tracking, and intuitive XR interactions.
Dynamic UI Customization: When accessing the Unity server via a browser, users are presented with a dynamic UI customization toolkit. This toolkit fetches available UI themes, a diverse set of UI elements (ranging from pie charts to text labels), and real-time data parameters, all retrieved in real-time from the server. This ensures that users always have the most up-to-date tools and data at their fingertips.
In a typical use scenario, a user, upon logging into the web interface, selects a machine type and role, and then crafts a custom UI using the provided toolkit. Once saved, a JSON configuration is generated and stored. When the AR glasses are activated in the vicinity of the specified machine, they query the server via the RESTful API, download the pertinent JSON configuration, and render the custom UI, offering the user a tailored AR experience.
This architecture, with its emphasis on modularity, real-time data flow, and user-centric design, positions the system at the forefront of industrial AR solutions, bridging the gap between complex data and actionable insights.
