Import FaceReader Videos Only

Aim

To import the videos of the test participants' faces into the observation in The Observer XT after you carried out the analysis.

Prerequisite

One of the following is true:

• You observe offline in The Observer XT.
• You control FaceReader with The Observer XT 14.0 or lower.
• You do not import FaceReader analyses as .odx files manually. When you import the .odx output of FaceReader analyses into The Observer XT, the FaceReader videos are also imported, so you can skip this topic.

Procedure

1. Open your observation in The Observer XT.
2. Click the Import video button on the toolbar.
3. Select your video file and click OK.
4. Synchronize the video file with the observation and imported FaceReader data. See Carry out an observation/Synchronize data sets in The Observer XT Help.

Import Multiple FaceReader Analyses Into The Same Observation

Aim

To import analyses of different test participants from the same experiment into the same observation of The Observer XT. You are, for example, interested in the interaction between a doctor and a patient. You want to import the analysis results of both the doctor and the patient into the same observation in The Observer XT.

Prerequisites

• You are interested in the interaction between two or more test participants. For example, a doctor and a patient, a teacher and a pupil, or a parent and a child. You want to import their analyses together into the same observation of The Observer XT.
• You exported the FaceReader data as .odx files.

  See Export analysis results

Procedure

To be able to import multiple analyses into the same observation of The Observer XT, the exported FaceReader data must be converted. Conversion adds a Subject to the data. Conversion is done with the Subject labeler.

To Install The Subject Labeler

1. Download the installation file from the Drivers & Tools section of the MyNoldus portal (my.noldus.com).
2. Double-click the file Subject Labeler Setup.exe.
3. Choose Standard as installation type and choose Next.
4. Accept the terms in the End-user license agreement and click Install.

To Convert The Export Files

1. Open the Subject Labeler.
2. Browse to the folder that contains the FaceReader export files. The .odx files found in this folder are listed in the ODX files field. The Subject column shows whether a Subject is present in the export file or not.
3. Select the files to add the first Subject to. For example, the analyses of the doctors.
4. In the Subject name field, enter a name to add as Subject to the files, for example Doctor.
5. Click Label. This adds the Subject name to the .odx file and the file name.
6. Repeat all steps for the other Subject, for example the analyses of the Patients.

To Import The Converted File Into The Observer XT

1. Open the observation.
2. Click the Import data button on the toolbar and choose Import Observational Data.
3. Browse to the converted file and select it. Then click Open.
4. If the question appears Do you want to import new coding scheme elements, click Yes, import new coding scheme elements.
5. A message appears that import is successful. Click Close.

Notes

• If an ODX file contains Subjects, it cannot be converted. FaceReader export files do not contain Subjects. However, The Observer XT export files may have Subjects.
• After conversion, the file appears in the ODX files field of the ODX converter. The Status column shows that this file contains a Subject and cannot be converted anymore.
• Importing multiple analyses into the same observation adds each FaceReader independent variable as a separate variable to the Independent Variables list of The Observer XT. Although the coding scheme contains Subjects, the independent variables have scope Observation.
• See Set up your project/ Create Coding Scheme/ Subjects in The Observer XT Help for more information on Subjects.
