Work With FaceReader

Setup

1. Dependent on your license, do one of the following:
   • If you have a software license key, start FaceReader and activate your license. You can choose between a Floating or a Computer-locked activation.
     • Floating License - Online Connection Required: Choose Floating if you want to be flexible on which computer you use FaceReader. Your computer needs to be connected to the Internet every time when starting up the software.
     • Computer-Locked License - Online Activation: A Fixed activation is linked to one computer. Your computer must have an Internet connection to activate/deactivate a fixed license. After you have activated the license you can use FaceReader without an Internet connection.
     • Computer-Locked License - Offline Activation: Use this option if your computer does not have an Internet connection. You need to use a smartphone with Internet instead.
   • If you have a hardware key, insert it into the computer and open FaceReader.
2. Create a new Project (File > New > Project). Give the project a name and select a location to store it, or accept the default location.
3. Choose Participant > Add Participant. Enter a name or identification code for the participant. You can also automatically add participants by selecting a video with multiple faces on the Multi-Subject Sources tab.
4. The gender and age of your participants are added as independent variables and are automatically estimated by FaceReader. To select the age and gender manually, double-click the participant name. Click on the pencil button next to the independent variable to enter the values.
5. Add one or more analyses for each participant and choose to analyze from video, live from your camera or from images. To do so, select the participant for which you want to add an analysis in the Project Explorer. Click on the Video, Camera or Image button on the toolbar to add the appropriate analysis. It is not possible to mix image analyses with camera or video analyses.

The Multi-Subject Sources tab is only available if you have the Advanced Research Module. On this tab click the Add multi-subject icon and select the video that you want to analyze.

6. To carry out a camera analysis, select the option Use as default camera if you always use this camera. To record audio, select your microphone. Optionally, select Record to create a video file of the test participant's face. The video will always be saved at a frame rate of 15 frames per second.

To add multiple video analyses to a participant, right-click the participant's name, select Add Multiple Video Analyses, and select your videos.

Analyze

1. Click on the magnifying glass button next to an analysis to open it.
2. Check the options for this analysis by clicking the Analysis Settings button at the bottom of your screen.

To create default settings for each new analysis, choose File > Settings. Open the tab Default Analysis Settings and make your selection.

The Application Settings panel includes the following sections: General, Default Analysis Settings, Analysis Options, Data Export, Visualization, and Advanced. Under Default Analysis Settings, you can select the Active Face Model. Available face models include General, Baby, and EastAsian. A Continuous calibration option is also available.

See the FaceReader Help for an explanation of the options. Press F1 in the program to open it.

Choose File > Settings > Analysis Options and select Action units, Consumption behavior, Vital signs and/or Voice analysis to activate the Consumption Behavior Module, the Vital Signs Module and/or the Voice Analysis Module.

Important If you select the Baby Face model, Facial expressions are not available as analysis output. You will obtain Action Unit intensities. See Action Unit Module in the FaceReader Help for more information.

3. Click on the Start analysis button at the bottom of your screen to carry out the analysis.
4. Tip To analyze all analyses at once, click on the Start batch analysis button on the toolbar.

Important Bear in mind that carrying out batch analysis on a high number of long videos with a high resolution and frame rate may cause problems.

5. The Model quality bar should cross the dashed line. If this is not the case, improve lighting or reposition your camera.
