Enviromatics meet Future Internet

Future Internet• Networking technology• Infrastructure as a Service• Internet of Things, Content,

People

INSPIRE, GMES, SISE• Geospatial• Environmental Observations• Model Web, Sensor Web, • Data Fusion, Uncertainty

ENVIROFI

FI-PPP Environmental Usage Area

• FI Requirements• Specific Enablers• Envirofied cross-area Applications

Page 4: Microlearning in crowdsourcing and crowdtasking applicaitons

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

Three learning strategies

Copyright © 2013 Denis Havlik, AIT Austrian Institute of Technology GmbH. 12

Classical: large information intake, well in-advance to use

Learning by doing: trial and error method

Illustration from: The Black Cat Diaries

Learning while doing: just in time intake of information in small portions

Biodiversity Personal environmental Information

Which species are common in my area?

What is my current and cumulative exposure?

What species is this? Am I allergic to pollen? Sensitive to weather changes? Ozone? …

Is it dangerous? Is any of the factors I’m sensitive to likely to occur tomorrow?

Is it edible?

Will it fall and ruin my car?

Support „learning while doing“

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

Other ideas?

Question: Which of these photos show maple leafs?

(known, maple) (known, oak) (unknown)

1. System mixes known and unknown samples 2. User can choose yes/no/can‘t say for each photo3. Correlate all answers to: (1) correlate known and unknown samples;

and (2) determine users level of knowledge4. Add feedback for training purposes
