Debriefing via the Web App
The Affect-tag RX Web App includes new features to help you verify, edit, and finalize your fieldwork.
After all data has been uploaded from all mobile devices, navigate to the Debriefing section of your project on the web application.
Uploading Media
Upload and associate any media to corresponding participant data sets.
The upload and association of media must be done at this stage and cannot be done after the project is marked as "Complete"
For more information on how to upload and associate media, see these articles:
Verifying Key Moments
A summary of Key Moments tagged for each participant is included in the third section of the Debriefing page, titled "3. Key Moments".
Clicking on the Participant ID opens a section that shows the names of all tags included in the data set for that participant by Phases, Snaps, and Standalone Tags. The Key Moments are listed in order of appearance and indicates the Experience to which it is attributed. Standalone Tags are not analyzed and therefore do not have an associated Experience.
This page is helpful for verifying that all Key Moments have been tagged properly. If this is not the case, or if any other changes need to be made, the Key Moment editor can be used.
Editing Key Moments
The Key Moment editor is a tool for editing fieldwork. With this tool, you can:
- Edit names of Key Moments
- Delete Key Moments
- Move Key Moments
- Edit colors of Key Moments (for appearance in the Individual Impact graphs)
- Add new Key Moments using the associated media (if applicable)
To edit Key Moments, click on the pencil icon in the row of the particpant data you want to edit to enter the editor. Phases are shown in the top portion of the timeline and Snaps are shown on the bottom.
Making changes to existing Key Moments
Click on the Phase or the Snap to edit the Name, Color, Time, or Date.
There is no "Undo" button. Once a change is confirmed the action cannot be undone.
Adding new Key Moments
If a media is associated with the data set, Key Moments can be added using the media as a reference.
Play the media and pause it at the instant the new Key Moment occurs. Choose the Experience and whether it is a Snap or a Phase.
- If it is a new Snap, click "Add Snap" and the new Snap will appear on the timeline.
- If it is a new Phase, click "Start" and play the media until the close of the Phase. Click "End" to close the Phase and the new Phase will appear on the timeline.
You can zoom into different portions of the timeline by clicking and dragging on the timeline window or by using the scroll bar underneath the timeline. Reset the zoom by clicking "Reset Zoom" in the upper right hand corner.
Click "Done" to save all changes.
Quality Control
The Quality Control section gives a summary of Fieldwork precision and Data Acquisition Quality by showing the number of samples registered. Samples are the pieces of data that have been cut up into Key Moments for each participant. The expected number of samples for a study is
Total Samples = Number of Experiences * Number of Key Moments * Number of Participants
Fieldwork Quality
In the Fieldwork Quality section, Experiences are listed as rows and Key Moments are listed as columns. Verify that the expected number of samples appears for each Key Moment and Experience.
If you don't see the expected number of samples, return to section 3 and verify that all Key Moments have been accurately tagged for each participant.
The bubbles that appear under the number of samples for each Key Moment is a Reliability Score. The Reliability is the ability of the results to be generalized for the tested population and it is based on the number of samples recorded. To understand how to increase the reliability score, see How do I increase my Reliability score?
Data Acquisition Quality
The Data Acqusition Quality section shows the number and percentage of samples with clean data. Choose the severity of the Signal Quality algorithm from Adequate, Superior, or Rigorous to manage the level of acceptable precision of the data. "Adequate" accepts sample withs slightly more noise, resulting in more samples analyzed while "Rigorous" uses only the cleanest data.
Launch the algorithm by clicking on the button in the top left corner of the box. If the severity is changed, you must relaunch the algorithm by clicking on the button again. For more information on the Signal Quality Index algorithm, see What is the Signal Quality Index?
The numbers shown are the final number of samples that will be analyzed along with the percentage of total samples for each Key Moment.
To view the final Reliability score for your chosen level of acceptable Signal Quality, toggle "Show Final Reliability".
