The Observer XT Sample Projects with FaceReader Data

On the MyNoldus portal of the Noldus website (my.noldus.com) under The Observer XT > Downloads > Sample projects, you can find two sample projects with FaceReader data for The Observer XT.

Child FaceReader

In this sample project the facial expressions of a child playing an online game are recorded in a media file and analyzed with FaceReader. Simultaneously, the Noldus screen capture device is used to create a media file of the monitor. With an Event marker the time intervals during which the child looks away were marked in FaceReader. FaceReader data, with Action Units, Stimuli and Event markers, and video files were imported into The Observer XT.

FaceReader & The Observer

In this sample project two test participants test the taste of three fruit juices. The time periods after the test participants drank each fruit juice were marked with Event markers. Each participant has been videotaped with two cameras, a webcam (for analysis in FaceReader) and a camcorder (to see what cup the participant takes). The FaceReader log files (Observer log and Detailed log), with Action Units, Stimuli and Event markers, have been imported into The Observer XT. The test participants' behavior has been manually scored.

In the Data profile Intervals by fruit juices, the time intervals after the participants drank each fruit juice were separated using the imported FaceReader Event markers Fruit juice 1, Fruit juice 2 and Fruit juice 3, respectively.

Under Behavior Analysis, you can find the archived Behavior Analysis State Expression Values per fruit juice, with an accompanying chart. For this Behavior analysis the data profile 'Intervals by fruit juices' was used.
