The Software for Video-Based Research

Qualitative and Quantitative Video Coding Software

Mangold INTERACT Software

Mangold INTERACT software on MacOS

INTERACT is the software for synchronized viewing and analysis of video and audio files in observational research.

Enabling content coding and event logging, it delivers valuable qualitative and quantitative results. Based on three decades of proven technology, it draws on the knowledge of thousands of researchers worldwide.

The INTERACT Video Coding and Analysis Software is used by more than 80% of all Top-100 Universities worldwide.

„Working with the Mangold team has revolutionized the way we run studies and analyze data ...

We've always been interested in the inter-relations between physiological systems, behavior and emotion in dyadic contexts. However, in the past we were largely estimating these relations over long periods of time. 

Using the INTERACT software system has allowed us to efficiently characterize the precise time course of behaviors and emotions, their inter-relations within an individual child and between children during dyadic interactions. We continually receive personalized customer support and know that the Mangold team will help us generate solutions to complex problems.“

Prof. Dr. Heather Henderson, University of Waterloo, Department of Psychology, Social Development Lab, Waterloo, ON, Canada

Unlimited Coding Options

Use individual coding systems of almost unlimited size and hierarchical complexity in INTERACT.

In INTERACT you can use and combine all common observation methods: Event sampling, Pinpoint sampling, Time sampling, Ad libitum sampling, Continuous sampling, Instantaneous sampling, Scan sampling, One-zero sampling - and variants.


The State-Space-Grid (Lewis, Lamey & Douglas, 1999) creates a graphical landscape of dyadic interactions that is important for measuring and understanding synchrony and flexibility in dynamic systems in activities or interpersonal relationships. 

Originally used for research on socio-emotional outcomes (acting, feeling, and thinking), the state-space grid in Mangold INTERACT software also has great value for analyzing any type of process, e.g., in teaching research (understanding teacher-student interactions or state changes in whole classrooms), ergonomics or usability research (understanding processes and workflows and measuring their efficiency), or similar applications.

The Mangold INTERACT State-Space-Grid implementation allows to render the collected codes in a time-dynamic diagram. This is very helpful to understand state changes and thus whole processes.

See how INTERACT Works

No matter how you call it - "video coding", "video evaluation", "tagging", "setting markers", "event logging", "content analysis", "content coding" "qualitative analysis", "quantitative analysis", "video rating" ... Mangold INTERACT does it all.

  • Method-Independent
    Use your own individual observation methods and coding systems with INTERACT
  • Unlimited
    Work with an almost unlimited number of videos simultaneously* in INTERACT and collect an unlimited amount of data.
  • Result-Oriented
    INTERACT can unveil hidden information in your observational data. Things that would take very long to find out without such a powerful software tool. 

See how easy INTERACT can be used in behavior research studies

* The program is only limited by the used computer's overall power and the typical limitations of its operating system.

A Best Practice Guide to Video-Supported Behavior Observation

Abstract: Observation appears to be a simple skill. It is assumed to be something everyone does every day since early childhood, and thus, it seems to be an easy and well-trained skill. However, observation of behavior with a scientific outcome is far from easy

The significant difference between everyday observation and scientific observation and the enormous chances specific software tools can create in this field will be discussed in this document.
