The Mobile Sensing framework addresses the following tasks:

• Read our various sensors
• Manage and control the recording of the sensors
• Write sensor data to local disk
• Sync data to a server system

Requirements

• Extentiability of mobile application for Activity recognition
• Flexible sensor management:
  • change rates while recording
  • control chunk size
• Rights management
• Energy efficience

Data Export and Exchange Format

• As easy/human readable as possible
• Dividable into smaller chunks (for transfer)
• Memory efficient

Implementation Details

Sharing large datasets between services Google

• via Intents
• via singleton Objects / Static Methods
• via Application Object
