Motivation

• Why? – Supporting ubiquituos informal learning by tagging the non‐obvious in digital video

• What?– Near‐real time collaborative multimedia annotation– Multi‐device & multi‐purpose

• How?– Cloud‐based Community Information System (CIS)– Seamless user interaction across platforms and devices– Community reflection and analytics using CIS success measures

EU FP7 Learning Layers Project

4

• How can we scale up video tagging to support informal learning at the work place?

• Objectives– Mobile creation of videos with learning 

materials (physical‐digital world)– Tag the non‐obvious for informal 

learning in communities (social media layer)

– Scaffold meaningful learning by exploiting (semantic) tagging information (social semantic layer)

• Two regional clusters– Construction (Germany)– Healthcare (UK)

Conclusions & Future Work

• Scaling up informal learning– Support communities, clusters and regional networks– Web services for scaling up– Open source development and cloud deployment– (Distributed) Web widgets and mobile interfaces

• Web engineering solutions & challenges– Strong and scalable service infrastructure– WebRTC and peer‐2‐peer– OpenID Connect (OIDC) for security and privacy
