ErgoAnalysis

This page shows how to download the data, analyze it, and make the pdf results for each work phase.

 

Downloading Data to ErgoLink

1.

PREPARE DEVICES READY

 

Start ErgoLink. Connect all the MCells and the ErgoMobile to the PC using USB-hub. Allow the PC to enter 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.

CREATE PROJECT AND PARTICIPANT TO ERGOLINK

 

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

3.

SELECT ALL RELEVANT PARTICIPANT DATA FROM THE MEASUREMENT SESSION

 

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

4.

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

 

In ErgoMobile, the heart Rate 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*\Documents
\Myontec\Ergo Analysis\*Start Time*\

Next, for the bottom box, select any and all video files, captured during the measurement. They are at path:
*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.

 

Preparing and Analyzing

the Data for Reporting

 

1.

CHECK DATA QUALITY

After opening the data, check that there are data sources from heart rate, emg, angles and video. The X-axis of chart represents time and duration of the measurement.

2.

SET MVC VALUES

To set the individual muscle maximum voluntary contraction EMG reference values, select 'Add MVC' using the cursor at the start- and endpoint of the desired area.
When successful, the MVC area will be highlighted with red color and values are shown.

By default MVC value is calculated using a 1-second moving average over the EMG signal. For each channel the MVC value is the maximum 1 sec average. If you wish to change the reference values, they can now be edited manually.

3.

SET ANGLE OFFSET REFERENCE  VALUES FOR ARMS AND TRUNK

Move the blue cursor to a point where the volunteer is keeping the arms and trunk steady, arms horizontally in 90 degree position. Click 'Set angles to zero' to enter to offset angles to correct position (left arm 90 degrees, trunk 0 degrees, right arm 90 degrees). When successful, the area will be shown in highlighted  blue vertical area in the data.

4.

SYNCHRONIZE THE VIDEO, EMG, AND ANGLE DATA IN LONG MEASUREMENTS

In long measurements (> 2 hrs) there may be appr. 5-15 seconds discrepancy in video, EMG,  and angle data. Correct the discrepancy in comparing the video and angle data by using the arm and trunk offset calibration movement data in the end of the measurement session. The amount of seconds in need to be  corrected can be calculated from the x-axis. Set the second values in data settings.

5.

ANALYZE WORK PHASES

Move the cursor to a desired area start, click 'Add AOI'. Move the cursor to the area end and click the button again. The selected area is highlighted with green hue and added to the AOI list. Assign any created task name to the AOI. Create as many number of tasks as necessary. Tasks may also be overlapping each other. Remember to save the data every now and then. 

Creating Project and Report to ErgoCloud

ErgoCloud enables easy sharing and a storage for the reports for each project.

 

1.

CREATE PROJECT TO THE ERGOCLOUD

 

At the project management page, choose the project from which you want to see the results as Quick Report. Click 'Create Project to Cloud'. The project should now be created under your ErgoCloud account. Project's name turns green.

2.

CREATE A QUICK REPORT TO ERGOCLOUD

 

Move to the page 'Create Quick Reports and Files to Cloud'. The reports page should list all the created tasks for the project. Select oneOn the right, select any or all measurement you wish to include to the report. Click the 'Upload Quick Report to Cloud'. You may give an additional description to the report. 

 

If everything was successful, you are done! Next log in to the ergo.myontec.com with your browser to view the Project and Quick Reports.

Working with ErgoCloud

1.

VIEW AND SHARE THE QUICK REPORTS

 

Log in to ErgoCloud to view your projects. You can view and share your selected Quick Reports with clients or partners. 

2.

USE THE ERGOCLOUD AS A STORAGE FOR PROJECT FILES, SHARED WITH YOUR CLIENT

You may download your own files (e.g. ppt, pdf, videos) to ErgoCloud and share them on the ErgoCloud with your network.
