Gathering data

The Observer XT allows you to collect meaningful data. Code behaviors accurately, record one or multiple videos, integrate data modalities, and explore your results.

Record all your data in sync with just one push of a button.

Code behaviors accurately 

The Observer XT is designed to reduce the amount of work and simplify behavioral coding. You can record subjects, behaviors, and modifiers by typing shortcut key codes, allowing you to keep your eyes on the scene, while coding at great speed. The time of each code is recorded automatically and errors are prevented by an on-line check. Up to 1024 characters per event can be used to comment on behaviors or write down notes. Text is presented in the event log and in a separate window.

Work with video and audio

The use of video adds great flexibility to behavioral studies. It allows you to make detailed observations and frame accurate descriptions of fast moving phenomena. Audio signals are visualized providing another great visual aid when observing behavior. Use the playback functions to easily position the video, play it back at different speeds, play it frame by frame, and play multiple videos at the same time. All data play in sync: when moving through the data, the video and audio follow and vice versa. You can set a loop in the video and audio files to code this episode in great detail, or use the quick review button to take a small step back in the video. After the observation, you can easily create a video highlights clip by using the improved episode selection.

With The Observer XT, you can combine data from different sources in your observation. The Observer XT is compatible with Viso and Media Recorder: software tools for recording video and audio. Viso is the multi-room video recording suite and Media Recorder is ideal when you want to combine up to 8 different video and audio signals from a wide range of different cameras and microphones. Videos can be stored separately or combined into one video stream. Of course the audio can be recorded in sync with the video.

"The Observer XT has helped me capture children's natural behaviors in an unobtrusive manner and this has added value to the behavioral interpretations I could draw. This tool is best suited for observational research where subjects can be observed without their awareness, which adds to the authenticity of findings. It is easy to use and gives data that can well be statistically analyzed” [Prof. Mayuri, India]

Questionnaire tool - uASQ

uASQ is a questionnaire tool which enhances The Observer XT with direct feedback from your test participant during a live observation. It enables you to ask your test participant three different types of questions: open ended, multiple choice, and Likert scale.

  • Combine video and event data with a participant survey.
  • Collect quantitative and qualitative data.
  • Find answers quickly by using the find functionality in The Observer XT.
  • Analyze data in The Observer XT.

User-system interaction - uLog

uLog™, an add-on module of the The Observer XT, is a tool for monitoring user-system interaction. 

  • Record user-system interaction automatically. 
  • Increase the consistency of user experience observations. 
  • Log Windows applications accurately and in great detail. 
  • Combine uLog and The Observer XT for optimal control, visualization, and analysis options. uLog is an add-on module of The Observer XT.
  • Select data of your choice using the advanced filter function in The Observer XT.

Mobile and multi-user solutions

Next to coding with The Observer XT, it is also possible to code on-the-go or work together on a research project. 

  • Code on-the-go using Pocket Observer. It combines the power of The Observer XT with the portability of a handheld computer, Android phone or tablet.
  • Coder Licenses will allow you to work together efficiently on a research project. They limit the use of The Observer XT to coding and visualization only.


"Related events can be identified quickly if the data has been coded using a  programme like The Observer, where codes/event logs are time-stamped and linked to the relevant video files. Systematic observation software is a powerful tool for archiving and managing large data sets.

Integrate data modalities

In The Observer XT overt behavior and physiological responses can be studied together. Synchronization is guaranteed by a continuous sync signal sent from The Observer XT, making the system immune to clock differences, drift, and missing samples. Sections of the physiological data correlating with interesting behaviors can be exported for further analysis. Read more about The Observer XT - the ideal integration platform.
