A Microservice Approach for Near Real-time Collaborative 3D Object Annotation on the Web

  1. 1. http://Learning-Layers.eu ICWL 2015 5-8 November, 2015 Guangzhou, China
  2. 2. http://Learning-Layers.eu • Motivation • Handling 3D objects in Web Browsers • Near real-time collaborative manipulations of 3D objects • Evaluation • Conclusion & future work 2
  3. 3. http://Learning-Layers.eu • Emerging 3D technologies (3D scanners, printers..) – Web-based access and manipulation – Access to hard accessible/expensive resources – High quality digital representations of physical artifacts • Support learning at scale – One to many, many to many (peer), one to one learning – Mix of personal and collaborative systems – Mix of informal and formal learning 3 annotations
  4. 4. http://Learning-Layers.eu • X3D – ISO (ISO/IEC IS 19775-1:2013) standard for 3D graphics handling – Emerged from Virtual Reality Modeling Language (VRML) • x3dom – Native support of X3D in Web browser 4 System Platform Domain Annotation Open Source [Settapat et al., 2014] MVC Framework Virtual Worlds Modern Pedagogy no no [Landro et al., 2014] Web portal Academic communities no no SmithsonianX3D Web-based Cultural Heritage yes no 3DSA Web-based Museums yes no ToBoA-3D Web-based Dedicated Virtual Environments yes no • Web-based annotation systems available • Open source libraries for 3D Web objects available • BUT not together 
  5. 5. http://Learning-Layers.eu • Developed in EU projects (ROLE, Metis, Layers) • Applied in Exploratory Teaching Space (ETS) at RWTH Aachen University together with hospital • Anatomy 2.0 Web Platform for tutors and learners – 3D object store – Near real-time collaborative manipulation of 3D objects in the Web browser – Lightweight persistent annotation of 3D objects • Personal Learning Environments (PLE) Renzel, D., Klamma, R., Kravcik, M., Nussbaumer, A.: ”Tracing Self-Regulated Learning in Responsive Open Learning Environments” – Designed for personalization, customization & adaptation – Awareness among participants 5
  6. 6. http://Learning-Layers.eu • Dedicated Website • Course creation and visualization • 3D object upload • Link to a Personal Learning Environment 6
  7. 7. http://Learning-Layers.eu 7 Community Space Members Widgets Chat HTLM5 Content Space
  8. 8. http://Learning-Layers.eu 8 • Widgets: 3D object store and 3D viewer widget • Annotation & shared handling supported in viewer • NRT collaboration enabled using XMPP protocol
  9. 9. http://Learning-Layers.eu 9 • Meso-level annotations (3D object level) [Cao et al. 2015] • Knowledge exploitation – Highlight the non-obvious information – Disambiguate meaning – Reflection (collaborative scenario) • Customizable and lightweight format
  10. 10. http://Learning-Layers.eu 10 • Microservice-based & widgetized • Graph-based annotation storage • Open source & standard-based
  11. 11. http://Learning-Layers.eu 11 • Early results obtained from ETS blended learning project – Two study sessions – 24 medicinal student participants • Target – Performance of annotations service – Usability of browser-based 3D objects
  12. 12. http://Learning-Layers.eu • Lightweight approach for collaborative manipulation of 3D objects on the Web – Open source development – Textual annotation and near real-time mechanisms – Evaluated using anatomical objects with good results • Know-how on fast prototyping of scalable technical solutions that can be succesfully used for learning • Challenges – New ROLE SDK release to allow flexibility and easy deployment/configuration in various learning settings – Integrate analytics using community monitoring and success measuring – Commsonomy usage for learning purpose 12
