Working with experiment DataLoggers

A DataLoggers handles logging experiment data to a 'csv' file. The default GameMaster already logs data automatically from all active sensors.

Creating logger

• Create data logger: DataStreamLogger motionLogger = new DataStreamLogger("Motion");
• Add to ExperimentSystem to automatically configure: ExperimentSystem.AddExperimentLogger(motionLogger);

Initialising log:

• A new log file needs to be added whenever a log wants to be used.
• Add new file: motionLogger.AddNewLogFile(session, iterationNumber, motionDataFormat);

Adding data to log:

• Example of sensor reading and logging:

            // Gather data while experiment is in progress
            string logData = taskTime.ToString();
            // Read from all experiment sensors
            foreach (ISensor sensor in ExperimentSystem.GetActiveSensors())
            {
                float[] sensorData = sensor.GetAllProcessedData();
                foreach (float element in sensorData)
                    logData += "," + element.ToString();
            }
  
            // Update data and append
            taskTime += Time.fixedDeltaTime;
  
            // Log current data
            motionLogger.AppendData(logData);
  

Closing log:

• To be called when finished using a log. motionLogger.CloseLog();
