AcqKnowledge 3.8.2 and above for Windows allows you to synchronize video files with physiological data. This allows you to jump to specific points in either the video or data file, and the corresponding data or video will jump to the correct time point. If you use a visual presentation system such as SuperLab, you can jump to the event markers in the data file and view the corresponding video.
Use an OUT103 LED cable to synchronize the video camera to the MP System. OUT103 connects to one of the analog output connectors on the bottom front UIM100C or the digital connectors on the back (for an MP150 system, the UIM will have to be separated at the MP150 side of the device to allow access to the heads of the screw terminals). To use OUT103 with an MP36R unit, add a BSLCBL6 interface cable and OUT3 adapter. In the software menu, under MP1XX>Setup Stimulator (in AcqKnowledge 4.4, choose “Stimulator” in the pane on the left after selecting “MP150 > Set Up Data Acquisition…”), use the stimulator settings to turn on the LED when the MP system starts recording data. Make sure that the video camera is recording and place the LED somewhere in view of the camera so that when you start recording you will see the LED turn on. When you review the video, you will see the LED turn on and that marks the start of the data acquisition. Use the timing measurements in AcqKnowledge to synchronize the video and data files.
The ETVision (ETV) wearable unit resembles an eyeglasses frame that can be worn by itself or over the participant’s prescription eyeglasses. It contains miniature “eye cameras” that view each eye and a “scene camera” that views the scene in front of the participant, and a microphone. An optional visor can be mounted to the front […]
BIOPAC provides software and hardware that allows research teams to study stimulus presentation data. Here are a few notable studies using BIOPAC equipment for research on stimuli’s effects using ECG and SCL data. Your Face Scares Me This study addressed the impact of individual differences in social anxiety by examining the effects of perceptual load and stimulus valence when […]
