This video gives a quick overview of Mangold INTERACT

With INTERACT, videos can be content-coded or rated and many statistical evaluations can be carried out. INTERACT is the perfect software for behavior observation and research studies in the field of human and animal behavior.

With INTERACT you can open and evaluate as many videos as you wish. All videos remain synchronized. This is very important if, for example, you are filming a scene with several cameras and then evaluating these videos together.

Of course, you can play the videos at any time at any speed, from quite fast to very slow. They can even go back and forth in single images.

You can also view the soundtrack for each video. This is very handy when the audio information is an essential part of your study. In autism studies, for example, it may be that an hour nothing is spoken. Suddenly the subject speaks a few words. With the audio presentation, you can immediately see this place and jump directly there instead of watching and listening to the whole video.

To code the content of the video you simply define a coding or aka category system. This can consist of any number of codes describing the events or contents that you want to evaluate in the video.

INTERACT allows you to use arbitrarily large category systems, which can also have any number of branches and hierarchy levels. This allows you to make very detailed speech analyzes, for example, by describing what you are observing very closely with various codes (for example: who says what to whom, why, with which intention, what tonality, what sentence structure etc.).

Of course, this goes with any content. For example, with the Facial Action Coding System (FACS), which describes the expression of each muscle in the face. Due to the intelligent structure of coding systems in INTERACT, the entire Facial Action Coding System needs, for example, only 3 levels to be fully usable.

Once the coding-system is defined, the actual coding process can begin. To do this, the videos are now viewed and the coder captures what she sees in the videos using keyboard shortcuts or mouse clicks. This can, as already mentioned, take place at any speed. Even if the video is paused, data can be recorded. INTERACT stores the data in so-called events. Each event always has a start time, an end time, and any number of codes

Of course, you can also carry out extensive transcriptions with INTERACT. You can add as much text to each event as you like

But that's not all. If you have additional data sources that you want to assign to a section of the video, such as PDF files, text documents, or spreadsheets, simply drag and drop them onto the text field of the event. With one click these can be called up again at any time.

As you can see in this example, events in INTERACT are always recorded in groups and sets. This is very useful, since you can already structure your data during the event logging. For example, use the data sets for the different subjects or the different test situations in your studies

You can even add independent variables to the data sets. You can define these completely freely. This allows you to select e.g. all female subjects or subjects at a certain age or situation with a few mouse clicks for post analysis.

Often it is necessary to code a video in several turns with a focus on different aspects. In INTERACT this is easily possible. Just set the video to the beginning, open a different coding system and capture your data as usual. Mangold INTERACT automatically ensures that all data are properly recorded.

You can also add new codes at any time to your coding system. And you can make manual corrections to your data at any time as well.

If the videos are coded, interesting statistics can be created with just a few mouse clicks. Simply click on the evaluation button. Here you can see again your entire coding system. Then you can select the data sets that you want to evaluate.

In the so-called time-line chart, INTERACT now displays all logged events on a horizontal timeline. With a click in the timeline, all the videos immediately jump to the appropriate location. When the video is playing, you can also see a line running through the chart that shows the current location of the video

Clicking on the evaluation button displays a series of statistical values. For example, the frequency, duration, and percentage of time of each code.

Everything you've seen so far is pure base functionality of INTERACT. All this was important to have any data that could be used for further evaluations.

The actual value of Mangold INTERACT is however not in the collection of the data, which of course is a very powerful range of functions of INTERACT. The value is now to draw information from these data, which cannot be detected by pure observation.

This is firstly the search for simultaneous events, or co-occurrent codes. If a research question is "how often is behavior A and B occurring at the same time", it would not be easy use this co-occurrence as a code for your observations. Simply because it is very difficult to capture several things at the same time cognitively.

The coding of A and B independently is probably much faster and more accurate, because you only need to concentrate on one thing and, maybe, can run the video even faster when you log events.

If you have recorded behavior A and B independently of one another, INTERACT will tell you in a few mouse clicks exactly where these behaviors occur at the same time. This data is again saved as events that you can evaluate statistically.

Similarly, you can examine contingencies or sequences of behaviors in your data, thus generating more and more information.

With this way of information mining, you get more and more complex results about the whole process from original simple codes. This is exactly what makes Mangold INTERACT so valuable.

Of course, you can also display and examine this data in any other way. Here is an example of the State Space Grid (SSG), which offers interesting possibilities and insights into your data.

And sure, INTERACT also provides methods to test the reliability of your coders. This is, for example, the Cohen's Kappa or the Intra Class Correlation Coefficient (ICC). These functions provide information on the quality of your data with just a few mouse clicks.

Finally, the integrated programming language of Mangold INTERACT must be pointed out. This allows you to extend INTERACT to meet your specific requirements. Write your own data import, export and evaluation functions, which can then be called directly from the INTERACT menu bar by your entire team.

This was just a brief outline of the thousand possibilities of INTERACT. Hopefully you have enjoyed the impressive overview of INTERACT in that video.
