Data collection with NoldusHub
NoldusHub is an all-in-one platform for multi-modal research, designed to save time and easily achieve trustworthy high-quality measurements and direct insights.
Which data can be collected using NoldusHub?
Combining multiple types of measurements can be quite challenging, especially when you use several acquisition tools that have to be calibrated and started. NoldusHub simplifies this process.
NoldusHub is at the heart of your data collection. The platform collects data from a webcam, eye-tracking device and several physiological devices. With these, you can measure a variety of signals and behavioral input.
Basic expressions can be analyzed, such as happy, sad, angry, and surprised, as well as a neutral state. In addition, the mental states interest, boredom, and confusion can be measured.
Gaze overlay and fixation
Stationary eye tracker
Observe the test participant’s gaze on a computer screen to get rich, quantitative, and reliable data for attention, mental load, and arousal.
Heart rate (HR) and Interbeat interval (IBI)
Electrocardiogram (ECG) and Photoplethysmography (PPG)
Detect changes in physiological measures and find out whether a test participant is active, or excited or scared. Choose ECG or the less invasive PPG, depending on your research needs.
Skin conductance peak rate
Electro dermal activity (EDA)
By measuring skin conductance peak rate, a physiological response not under conscious control of the participant, you get an indication of psychological arousal. For instance, whether a person is anxious or startled by a trigger.
Audio & video
Postures, movements, nonverbal and verbal behavior - all can be observed to get a complete insight into the participants behavior, responses, and motivations.
Screen capture software
See which images, video, or website the participant is watching during a test.
Research leader station
You can mark events of interest during or after the recordings, using a self-created markerlist.
