The Observer XT


Two modules to extend the Base version

The Base version of The Observer XT allows for study setup, coding scheme design, live coding, offline editing, general analysis, reliability & lag sequential analysis, and presentation of behavioral data. Depending on your research needs, you can extend this basic system with two modules:

Media Module
For synchronized playback of multiple video files during the observation, and offline scoring of digital media files. All visualized on one timeline.

External Data Module
Combine external data (collected with data acquisition systems) on one timeline in The Observer XT. Then analyze external data and behavioral data all together.

uLog: the tool for user-system interaction

uLog automatically records user-system interactions, such as: 

  • Keystrokes, special keys (e.g. space bar), key combinations 
  • Characters, text strings
  • Mouse clicks, double clicks, mouse wheel turns 
  • Windows activated, message box activated
  • Applications started or ended

To avoid misuse, uLog shows an icon to inform the user that keyboard logging is active. Starting and stopping of event logging is automatically synchronized with other observational data, and the event log is imported into your The Observer XT project.


uASQ: the questionnaire tool 

uASQ 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. 

In The Observer XT you can easily select data for analysis: for example filter by choosing only test participants who agreed with a certain statement. Both Likert Scale questions and Multiple Choice questions can be analyzed quickly. 

  • Combine video and event data with a participant survey
  • Collect quantitative and qualitative data
  • Analyze data quickly and easily in The Observer XT

Stimulus presentation tool E-Prime

To present stimuli to your test participants, you can use E-Prime in combination with The Observer XT. E-Prime is the stimulus presentation program widely used in psychological research. 

E-Prime sends the collected data to The Observer XT immediately after the session. The collected data is then visualized as behaviors and modifiers in The Observer XT; including the time at which the stimulus was given, which stimulus it was, and how the participant responded to the stimulus. 

If you want to use The Observer XT in combination with for example FaceReader, an eye tracker, E-Prime and physiological data, this new solution is perfect for you!
