Using a webcam video recording during an OpenSesame experiment

Anaïs95

Hello,

Is it possible to sync a Webcam with an OpenSesame experience to record a participant's video while performing the experiment? Is it possible to have video recordings play during the presentation of certain visual or auditory stimuli?

In advance a big thank you for your help!

Sincerely,

Hi Anaïs,

You're mentioning a few things. All of them are possible in principle, but depending on what you want to do this may require some programming skills.

Is it possible to sync a Webcam with an OpenSesame experience to record a participant's video while performing the experiment?

The easiest solution would be to record the webcam with another program, and then afterwards sync the recording with the experiment data. To make syncing easier, you could record audio along with the video feed, and have the experiment play a beep sound every once in a while. This will give you some auditory markers in the recording.

Alternatively, you can use opencv to programmatically record video, but that may be more trouble than it's worth.

It is tricky to combine presentation of other stimuli (especially visual) with video playback. A pragmatic solution would be to edit the videos and add the stimuli to the videos themselves. In that case, all you need to do is play the videos.

Cheers!
