Physiological measurement systems
水果视频app官网Noldus offers several data acquisition systems that work in conjunction with The Observer® XT. You can benefit from synchronous recordings of physiological data, video, and behavior.
Take advantage of a fully integrated set-up
- Synchronize physiological responses with behavioral coding
- Measure the internal state of your test participant
- Collect ECG, EEG, skin conductance, respiration, and more
Record all your data in sync with just one push of a button
While you are collecting observational data, you can simultaneously acquire physiological data, such as EEG, ECG, EMG, blood pressure, or skin conductance, with an external data acquisition system.
Although you can add your own system, Noldus also offers several data acquisition systems that work in conjunction with The Observer® XT. You can benefit from synchronous recordings of physiological data, video, and behavior.
Improved FaceReader integration
Emotion analysis is often included in a lab set-up. FaceReader videos can now automatically be linked to a live observation in The Observer XT and synchronized with the events. Also, multiple FaceReader instances can be controlled with one instance of The Observer XT.
In addition to this, FaceReader allows you to import analyses of multiple persons into one observation in The Observer XT. This is useful if you are interested in the interaction between test participants.
BIOPAC AcqKnowledge integration
Control of physiological data acquisition with a BIOPAC system has improved. Communication between BIOPAC AcqKnowledge and The Observer XT now makes use of the Noldus network communication protocol N-Linx. This simplifies start and stop of physiological data acquisition and synchronization with the Event Log in The Observer XT.
Tobii Pro Studio integration
Next to physiology, researchers often also collect eye tracking data. Communication between Tobii Pro Studio and The Observer XT now also makes use of the 0204jp.netmunication protocol N-Linx. This simplifies start and stop of the eye tracking recording and synchronization with the Event Log in The Observer XT.
The Observer XT and E-Prime
水果视频app官网E-Prime from Psychology Software Tools is a stimulus presentation program widely used in psychological research. The combination of The Observer XT and E-Prime provides insight in the relationship between behavior and presented stimulus. If you want to use The Observer XT in combination with for example FaceReader, an eye tracker, E-Prime and physiological data, this integrated solution is perfect for you! After the experiment the data from E-prime is automatically transferred to the Observer XT and all actions are synchronized on one time-line in The Observer XT.
E-Prime Studio 3.0 support
水果视频app官网A new version of the E-Prime client and server are released with The Observer XT, so that it supports E-Prime Studio 3.0.
Prof. Julien Mercier: "Data integration is really where everything begins and ends"
水果视频app官网Prof. Julien Mercier from L'Université du Québec à Montréal (UQAM) is studying educational research. His lab is looking at refined brain information over time, involving the cognition and the affect of the learner.

Physiology and multimodal research
水果视频app官网Although your test participant may appear to be calm, he or she may be concealing a considerable amount of stress. To reveal this level of stress, you can combine behavioral coding with physiological measurements acquired with a data acquisition system. For example, skin conductance is a method of measuring the electrical conductance of the skin which is used as an indication of psychological or physiological arousal.
A combination of physiological and behavioral data can provide you with essential information that will help you to further understand and explain your participants’ behaviors. Noldus can support you in measuring:
- heart rate
- skin resistance
- skin temperature
- muscle tension (EMG)
- neuronal activity (EEG)
- and more
Data acquisition systems enable you to study almost any research topic involving emotions, or mental and physical load. We help you build the right solution, consisting of a data acquisition system and The Observer XT, the ideal platform for multimodal research.
