Workshop Learning Outcomes
• Understand nuts & bolts of informal learning
• Understand how outcomes of collaborative work at workplace can be used to scaffold informal learning
• Apply adaptive video strategies to support learning
• Apply your own ideas for personalization

Motivation
Discussions with stakeholders revealed requirements that
can be solved by using multimedia in workplace scenarios
How to support informal learning at the workplace by video
annotation and video adaptation techniques?
Challenge: select scenes relevant in a particular context and
present them accordingly

Workplace Learning
Workplace learning is mostly informal
– No set objective in terms of learning outcomes
– Not intentional from the learner’s standpoint
It maintains important principles of education
– Authenticity, Engagement, Demonstration
Domain knowledge of experts is often ill-structured
– Content complexity
– Irregularity of application contexts
Cognitive Flexibility Theory (Spiro & Jehng, 1990)
– ability to spontaneously restructure one's knowledge, in many ways,
in adaptive response to radically changing situational demandsSpiro, R. J., & Jehng, J. C. (1990). Cognitive flexibility and hypertext: Theory and technology for the nonlinear and multidimensional traversal of complex subject
matter. Cognition, education, and multimedia: Exploring ideas in high technology, 205.

EU FP7 Learning Layers Project
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) http://learning-layers.eu/

Use-Case
Adaptive Video Presentation
A Web-based video adaptation tool
– Informal learning support
– Adaptive video presentation based on
– User profile (preferences)
– Collaboratively created video annotations
Objective
– Choose relevant segments from different videos to form
an adaptive video, personalized for a particular user

Adaptive Video Presentation
Aim: adapt annotated videos according to the current
demands & meta-data on Content, User, Context
FOSP Method to specify adaptation strategies
– Filter: take only relevant components (segments)
– Order: order them accordingly
– Select: choose from alternative representations
– Present: responsive design

Task: Adaptation Strategies
Team up
Choose a scenario for applying video adaptation– E.g. Construction, Healthcare
– Keep in mind the learning objective
Specify a video adaptation strategy for learning– Situational context
– User information needed – How to acquire the information
– What users should specify (explicit info)
– What can automatically collected (implicit info)
– Video presentation – How to filter & prioritize information
– How to present (any important UI concerns)

Relevant Information
User profile information => User Metadata
Video annotations (type, content) => Video Metadata
Contextual information (location, weather) => Context
Adaptation strategies => Adaptive Presentation
– Filter: select relevant segments
– Order: rank information according to different criteria
– Select: choose most suitable representation (media,
perspective)
– Present: responsive design (parallel vs. sequential)
