Frequently Asked Questions

What is Mangold INTERACT and what is it used for?

INTERACT is a software for behavioral coding and video analysis in observational research. It enables the coding, transcription and analysis of audio and video recordings with custom coding schemes – supporting event sampling, time sampling and continuous coding across multiple synchronized audio/video files. Researchers in psychology, neuroscience, ethology, UX research, education and similar fields have relied on it for over 35 years.

How does Mangold INTERACT differ from other behavioral coding tools?

INTERACT offers three structural advantages that are unique in this combination: (1) Native macOS and Windows support with 100% data compatibility – one license for mixed Mac/PC teams. (2) Python integration for custom analysis workflows with access to thousands of scientific libraries. (3) GDPR-compliant AI transcription that runs offline on your own computer – no cloud transfer of sensitive research data. Methodologically, INTERACT covers the entire research workflow in a single tool: data acquisition, data management and advanced data analysis – including state-space grids, lag sequential analysis and contingency analysis.

Is INTERACT an alternative to open-source tools?

Yes. INTERACT offers the flexibility of open-source behavioral coding tools, complemented by professional support, AI transcription, multi-data-stream synchronization (sensor data such as EEG, ECG, motion, etc.) and powerful analysis tools. Mangold has been continuously developing INTERACT for 35+ years and additionally provides scientific guidance, training and direct points of contact – added value that is structurally missing from open-source tools. This becomes particularly relevant when complex questions about data acquisition or data analysis arise during a project, or when technical issues occur (typically: Windows / macOS / Python updates) and the software being used suddenly no longer runs smoothly mid-project.

Which video formats does INTERACT support?

INTERACT supports most common video formats, including MP4 and AVI – also recordings from smartphones, action cameras and professional equipment. Multiple video files can be played back and coded in sync, regardless of source or frame rate.

Which data modalities can I synchronize with INTERACT?

Using the DataView add-on module, INTERACT synchronizes video and audio recordings with physiological data streams such as EEG, ECG, GSR, EMG and accelerometry, or any other data stream that contains numerical values and time stamps or a known sampling rate. External data streams can be imported via standard formats such as EDF, BDF and CSV and linked precisely in time with observational data – ideal for multimodal behavioral research, when qualitative content coding is to be combined with quantitative measurement data.

How does the Whisper AI transcription in INTERACT work?

INTERACT Premium uses the Whisper AI model exclusively offline on your local computer. It does not transfer any audio data to external cloud providers, is therefore GDPR-compliant and supports speaker diarization and recognition. This allows audio and video files to be transcribed fully automatically and integrated directly into your coding analysis.

Can I calculate inter-rater reliability with INTERACT?

Yes. INTERACT includes built-in tools for calculating inter-rater reliability (IRR), enabling multiple coders to work independently on the same dataset and then compare results using standardized agreement measures such as Cohen's kappa.

Can I automate analyses in INTERACT?

Yes. INTERACT includes an integrated workflow editor for building reusable analysis routines. For advanced automation, the Python integration allows you to write custom scripts for data manipulation and analysis directly within the INTERACT environment.

Does INTERACT run on Mac?

Yes, Mangold INTERACT runs natively on macOS and Windows and offers 100% cross-platform functionality and data compatibility. A single INTERACT license can be used on both platforms, allowing you to work in a mixed system environment with Windows and macOS devices.

What licensing options are available – including for universities and students?

INTERACT is available in three packages: Basic, Professional and Premium. A free trial version can be requested. Special conditions for educational institutions and students are available on request.
