COLLECT SENSOR DATA IN THE BACKGROUND

Both the Apple and Android ilumivu apps provide you with the option to passively collect data from the phone or tablet’s internal sensors including:

  • Geographical location from GPS coordinates taken each time the participant completes a survey. We are currently adding the ability to take periodic GPS samples in the background and trigger surveys based on proximity to specified locations.
  • Accelerometer data – either raw, 3-axis accelerometer data or a rolled-up “significant movement” measure
  • Screen on/off time
  • Screen locked / unlocked time
  • Proximity (phones only), i.e. if the phone is being held close to another object.
  • Light levels
  • Sound levels
  • Voice detection
