1.

PREPARE DEVICES READY

 

Start ErgoLink. Connect MCell and a smartphone with ErgoMobile app to a PC using USB port. Allow the PC to access the phone's memory by confirming the message on phone's window (see picture). It is recommended to use an external hard drive for the data storage.

​

​

​

​

​

​

2.

DEFAULT SETTINGS AND NAVIGATION IN ERGOLINK

​

Set the right folder path, where the data will be located

Enable automatic logging to ErgoCloud for regular use

3.

CREATE PROJECT AND PARTICIPANT IN ERGOLINK 

On ErgoLink's page 'Project management' create a 'Project' for the data. Select the Project and create a 'Participant' with the participant's information collected in the Participant Questionnaire. Obligatory items are marked with stars (*).  

Or select existing measurement file click open (or double-click the measurement) 

 

4.

SELECT ALL RELEVANT PARTICIPANT DATA FROM THE MEASUREMENT SESSION

 

Select the Participant and head to the page 'Download Measurement'. Make sure the MCell device and the phone is visible on the Download page. You must download all data from all devices at the same time in order to have synchronized video, EMG, and angle data.

 

Under MCell device, select the correct starting time of the measurement to the dropdown box.

 

In ErgoMobile, the IMU dots data is stored in DOCUMENTS and videos are stored in PICTURES under the folder MYONTEC. For the phone, to the upper box, select the measurement file ('start_time.csv') from the phone's memory. It is stored at: 
[Phone root]\Internal shared storage\Android\data\com.myontec.mbody_ergo\files\ErgoAnalysis\[Measurement start time]

Next, for the bottom box, select all video files, captured during the measurement. The path is:

[Phone root]\Pictures\Myontec\Ergo Analysis\[Start Time]\

​

When all is selected, check that all seems OK and click 'Transfer Files'.

5.

DATA IS READY

 

The data should now appear as a file under the selected participant. Open the file by double-clicking it. You will see the synchronized data in ErgoLink participant page.
