Prerequisites

• Your FaceReader license includes the Project Analysis Module.
• You have a video or camera analysis.
• You defined Event markers.

Procedure

To Score During An Analysis

1. Press the trigger key that is associated with your Event marker. If you have the Timeline window open, a bar appears in the line Event markers.
2. Press the same trigger key to stop the Event, or press another key to start another event.

To Score After An Analysis

1. Open the Timeline Window and scroll the video to the position where the event starts.
2. Press the Event marker trigger key. A question appears whether you want to score the Event marker at that point. Choose Yes.
3. Scroll the video to the position where the Event marker should stop.
4. Press the same trigger key to stop the event, or press another key to stop the event and start another event.

Notes

• Scored Event markers appear as dots below the analysis in the project explorer.
• To edit a scored Event marker, unfold the analysis and double-click Scored Event Markers. In the window that opens, edit the markers by dragging them to the correct position.
• To copy a scored Event marker to other participants or analyses, unfold the analysis and double-click Scored Event Markers. Click the Event marker you want to copy. Click Scored Event Markers at the top of the window, and choose one of the options under Copy To.

Independent Variables

Independent variables are factors that can vary but are constant per participant and can, potentially, affect the analysis results. Examples are the nationality of the participant, or the previous experience with a product or commercial. Independent Variables can be used to compare participant groups, for example to compare groups of males and females, or to make groups with and without previous experience with the product.

By default, each project contains the independent variables Age and Gender of the participant. These cannot be deleted. Their values can be estimated by FaceReader, from the analyzed images. Alternatively, you can enter the values manually.

Independent Variables must be scored for each participant. Participants for which one or more Independent Variables have not been scored are left out of the analysis.
