Motivation
• Wearables fit WELL to informal learning ideas
– Industry 4.0
– Smart workforces
• Example: EU funded project Learning LAYERS
• High demand for information about new tools,
new construction materials, new methods
• Brick and mortar construction sector
turns into high-tech knowledge industry
– Changing workplace situation demands new integrated concepts
for teaching and learning with wearables
• Gained understanding of the use cases and technologies
needs to be persisted in open standards, open source
support libraries and public documentation

Pedagogical
•Creating
understanding of how
new tools, materials &
procedures work
•Reaching many
people & spread
knowledge rapidly
•Support sustaining
community of practice
Technological
•Service discovery:
what is available?
•Experience building:
what can apps do?
•Entrepreneurial
context
•Rapid prototyping
•Scaffolding
•Attracting non-
technical context
•Exploitation
Implementation
•Experience building
•Rapid prototyping
•DevOps

Learning Case: Permanent
Construction Exhibition
• Center for Sustainable Construction in Northern Germany
• Building with straw & clay
– Renaissance of a superseded technology
– Multi-story house as demonstrator and proof of concept
• Informing private companies, house builders, architects,
construction workers about how to build with straw and clay

Open Source Strategy
12
https://github.com/learning-layers/
• Success Factors
– Street credibility (takes time & commitment)
– Permissive Open Source License
– Talking about it, e.g. FOSDEM, Mindtrek
– Using state-of-the-art technology & workflows
• DevOps

13. http://Learning-Layers-eu
Agile Development Method
DevOps Life Cycle
• Rapid release cycle
• Strong feedback loop
• Dev and Ops working
hand in hand
But where are the
designers and users?

14. http://Learning-Layers-eu
Conclusion
• Industry 4.0 with a myriad of new learning
cases and scenarios
• Understanding of pedagogical, technological
and implementation challenges needed
• Exhibition as learning case for interacting with
physical items
• Open source software and documentation for
experience building
14

15. http://Learning-Layers-eu
Open Challenges
• Context Adaptation
– How to design apps that are aware of the learner’s
surroundings?
• Continuous Innovation
– How to invite end users, designers and developers
to discuss new ideas and solutions?
• Scenario Extension
– How to include things like gamification and
sensors?
