Tower of Hanoi Active Task Export Format

The Tower of Hanoi Active Task is based on the ResearchKit Tower of Hanoi task.

When your project uses the CSV export format for Survey Results, data for Active Tasks is exported in the file SurveyTowerOfHanoiResults.csv. When your project uses the JSON export format, Active Task data is included in the file SurveyResults.json.

For a typical survey using this task, you'll expect to see:

  • One survey result each time the participant completes the survey.
  • Detailed information on each action taken during the survey.
