Discover the Invisible Through Tool-Supported Scientific Observation

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. It requires a well-thought-out method based on scientific knowledge and hypothesis. It further requires appropriate software tools to create reliable data and new findings with significant validity in a reasonable time

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.

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.

INTERACT Video Import


Easy to Use

During over 30 years of continued development of INTERACT, we always focused on intuitive usability and maximum flexibility.

The almost magic video technology in INTERACT allows for using any common video format in your studies. It can handle videos from digital camcorders, IP-cameras, streaming videos, action-cams, web-cams, smartphone videos etc. - just give it a try if you already have INTERACT, or ask us in case we should test one of your videos for you.

Also, using videos from different camera types simultaneously is easily possible - such as a video from an action-cam, another one from an Android mobile phone and another one from an iPhone.

INTERACT offers unlimited coding and transcription possibilities for beginners and professionals.

Unlimited coding and transcription possibilities

With INTERACT, complex coding/category systems can be used without restrictions
An unrestricted transcription is also possible at any time.

From the requirements of various projects in over 30 years, essential functions have been developed in INTERACT, which are easy to use and allow hundreds of variations of coding methods. From simple coding at the push of a button to structured post-coding and the coding process where several event streams are recorded in parallel.

INTERACT offers every user the right possibilities, from beginners to professionals.
