Multi-Respondent View is more than just a pop-up or pop-out window. Multi-Respondent View allows you to easily compare individuals in focus groups. This gives you all the options you have in the iMotions Replay window for two or more respondents.

What is Replay in iMotions Lab?
In iMotions Lab, Replay is the analysis window that shows individual respondents’ physiological signals, annotations, markers, respondent recordings, study stimuli, eye-tracking gaze, and more.
What can I use Multi-Respondent View for?
- Compare Study Participants: Multi-respondent view is helpful for simulator studies in which you test multiple drivers or pilots and you want to compare their attention, emotional expression, or cognitive load during particular events. This is also ideal for psychology and communications research with dyad studies!
- Track Individual Progress: Multi-respondent view is useful for looking at an individual’s progression. If a respondent was in a study before a clinical treatment or specific sports training and then in the same study again afterwards, you can use these views to closely examine their development.
- Create Data Visualizations: Sometimes you want to show an example of a participant that represents one group next to a study participant that represents another group, so that people are clear on the differences between the groups. Multi-respondent view makes it easier to visualize individual data, side-by-side (see video below).
Synchronize your playback with Sync Markers
In iMotions, you can include various types of data analysis markers in your analysis. They fall under three main types: event markers, analysis markers, and manual markers. With multi-respondent view, data analysis markers can be used to align signals and playback across respondent replay windows.
- Event markers: Data Analysis markers related to the stimulus or data collection. Examples of events include the start and end of a video or recording, activation of certain hardware, or triggered events in the study.
- Analysis Markers: Data analysis Markers based on the data from the biosensors or events related to data analysis. This could be signal peaks for something like EMG or AOI activation for AutoAOIs.
- Manual Markers: Data Analysis Markers that researchers add after data collection, for example, while doing behavioral scoring. The video below is an example of manual markers added to denote scenes in a screen recording.
In iMotions Lab, markers are data analysis tools that occur at a specific point in time. Annotations are similar, but cover a range of time. Want to see more iMotions data analysis tools like markers and annotations in action?
Video: Synchronize Multiple Respondents in Replay
In the video above, you can see the Replay video for two different respondents. The top is the screen recording from playing a video game. Below this, you can see signals for engagement (mustard yellow) and blinks (teal). The very bottom shows two manual markers, one for the start of choosing a character and one for the start of choosing a vehicle.
Because respondents can go through the video game at their own pace, each will select a character at a different time. Using the manual marker, we can align their videos to see the participants choose their characters simultaneously. They spend a different amount of time choosing a character, and then choose a vehicle. Again, we align on vehicle choice marker. Here we can easily compare respondents and see that we can one player is spending more time looking at the vehicle specifications than the other.
