Sound and User Camera
When collecting eye tracking data, it is often desirable to also record user sound, and sometimes even the user’s facial expres-
sions. To be able to record facial expressions you must attach an additional webcam to your computer running Tobii Studio.
Most webcams can serve as a user camera. However, we do not recommended using the same camera type for both scene
camera and user camera, as this might cause conflicts in the software.
To record user sound:
1.
Make sure you have configured the scene camera.
2.
In the Global Settings dialog box in Tobii Studio (Tools>Settings), select the Screen and Video Capture tab.
3.
Select the Audio checkbox.
4.
In the Audio Source dropdown menu, select “Microphone HD Pro Webcam”.
5.
Click OK to close the dialog.
To record user camera:
1.
Make sure you have connected and installed the extra web camera that you want to use as user camera.
2.
In the Global Settings dialog box in Tobii Studio (Tools>Settings), select the Screen and Video Capture tab.
3.
Select the Record User Camera checkbox.
4.
In the Source dropdown menu, select the camera that you intend to use as user camera.
5.
Change camera and video settings according to your specifications. Use a resolution of max 640x480 to minimize the
load on the computer. Use Microsoft Video 1 codec if you can for the user camera video.
6.
Click OK to save the settings and close the dialog.
