ENVIROFI Scenarios
1. Bringing Biodiversity into the Future Internet• Enabled biodiversity surveys with advanced ontologies• Analysis, quality assurance and dissemination of biodiversity data
2. Personal Information System for Air Pollutants, allergens and meteorological conditions
• Enhance human to environment interaction• Atmospheric conditions and pollution in “the palm of your hand”
3. Collaborative Usage of Marine Data Assets• Assess needs of key marine user communities• Selection of representative marine use cases for further trial:
leisure and tourism, ocean energy devices, aquaculture, oil spill alert

Microlearning helps!
Copyright © 2013 Denis Havlik, AIT Austrian Institute of Technology GmbH. 9
Objective Possible approach
How to use the application? Tooltips or popup messages on first use (implemented)
Training to recognise objects
Scavenger hunt for known and tagged objects
Learn to avoid misidentifications
control questions & feedback
A-posteriori feedback Notify user when more info on the object is available (implemented)
Classify data & assess users knowledge
Generalized re-capcha principle
Microlearning in a sense of „learning while doing“ is crucial for quality of information but still not sufficiently taken into account. On TODO list.

Challenges: tracking of users?
Work with „Areas of Interest“: •defined by users•Could be automatically generated when user significantly moves
Why AOIs?1.pre-fetching of data => allows offline use2.Server-side filtering of events
No tracking!Current users position is taken into account by the Mobile app logic!

data (e.g. health-related) on the backend
server?

Ultimate challenge: industrialization
We are transforming the ENVIROFI experiments into a
reliable and scalable FOSS product.

Ultimate challenge: industrialization
First public presentation of “UBICITY” by Jan von Oort is
tomorrow! (11:20-11:40 - during coffee break)

1. The ideas presented today were developed and partially realized as Mobile Data Acquisition System (MDAF) in the scope of the European Community's Seventh Framework Programme (FP7/2007-2013) under Grant Agreement Number 284898 (ENVIROFI)
2. The importance of microlearning really became clear to me very recently, thanks to Dr. Christian Voigt and the microlearning 7.0 conference.
3. MDAF contributors: Eun Yu, Clemens Bernhard Geyer, Peter Kutschera, Markus Falgenhauer, Markus Cizek, Ralf Vamosi, Maria Egly, Hermann Huber and most recently Jan von Oort.• Currently active developers are underlined.
