2. About
Phone as a sensor model.
• Smart phones as an ideal platform for collecting
and processing context-related data.
• Computational social science, crowdsensing
• An an attempt to describe and categorize existing
open source libraries for mobile sensing,
• Describe architecture and design patterns
• Discover directions for the future development.

Conclusion

4. Introduction
• Rich sensing capabilities for smart phones
• Collecting data about people’s social behavior
(computational social science – e.g., Reality
Mining)
• Crowd-sensing for business-related tasks (e.g.
OpenSignal)
• Balance between energy efficiency, data
collection, storage, and transmission procedures

5. Challenges
• Batteries as a major challenge in achieving
social sensing
• Sensors power consumption: GPS vs.
accelerometer
• Context-aware data collecting. E.g. reuse
location for phone on the table, SD card vs.
cloud storage, etc.
• High level of diversification in mobile sensors

6. External collections

7. Open Source Frameworks
• AWARE framework: client + server

8. Open Source Frameworks
• FUNF framework

9. Open Source Frameworks
• Open Data Kit

10. Challenges for Open Source
Frameworks.
• Context-aware data collecting. How to
reduce measurements and data
transmission
• A flexible data management. SD-card vs.
Cloud
• Portable (common) data formats
• Built-in data processing

11. API vs. DPI
• Traditionally: mobile OS presents API for
built-in sensors
• APIs used by mobile applications
• The standard approach for crowd-sensing
is to split data collecting and data
processing
• So, we have to switch to DPI – Data
Programming Interfaces

12. Conclusion
• A survey of the Open Source tools
for mobile sensing.
• Existing projects
• Directions for the future research
• The prediction: we will see mobile sensing as a part
of mobile OS
• An existing example: iBeacons в iOS
