This document discusses the potential for sensors and big data in health and well-being. It highlights Google Flu Trends, which was found to be wrong in its predictions 100 times out of 108 weeks. It also discusses the challenges of big data in health, including issues with data variety, veracity (accuracy of sensors, manual entries, and missing data), and privacy concerns. The document promotes tracking health metrics like exercise, weight, and calorie intake but notes the ecosystem is still facing challenges to realize its full potential.

Hinweis der Redaktion
- Animation of predicted flu occurrences by State Predication based on 45 Google search terms
- Google results published in Nature in 2008 Study by Northeastern and Havard Universities (published in Science) Prediction too high, sometimes double Previous week’s occurrences more accurate Google tweak their algorithms – increases uncertainty Accuracy far greater before autocomplete introduced in 2009
- Deriving value from the data
- We are what we eat…and do Eating Exercise Weight
- What about other exercise? Weights, pilates, circuits …
- Incentive: Gameification/competition
- All different!
- Manual entry: Fine for foods Provenance of data, what sensor generated the data?
- Who can see my data? How is my data used?
- As much about educating the public Public relations
