EYE TRACKING AND EMOTIONAL RESPONSE ON THE FACE

The equipment for eye tracking and reading emotional responses based on facial expressions allows us to identify which aspects of the stimuli capture the most attention and what emotional reactions they trigger in individuals.

Tobii Pro X-120 - Eye Tracking Device

The Tobii Pro X-120 is an advanced eye tracking system designed for precise analysis of gaze and attention. The device uses eye movement detection technology to measure where and how long an individual looks, as well as to analyze visual responses to various stimuli. It also detects pupil dilation.

Noldus FaceReader

FaceReader is a software system for analyzing facial expressions. It uses a camera and advanced algorithms to detect and interpret emotional states, enabling the recognition of various emotions such as happiness, sadness, anger, surprise, fear, and disgust.

MEASURING PHYSIOLOGICAL RESPONSES

We use BIOPAC hardware and software to track physiological responses to a wide range of stimuli.

System for measuring respiratory rate and cardiac electrical activity (ECG)

The Biopac BioNomadix wireless module captures data on both respiration and electrical activity of the heart (ECG), allowing for simultaneous recording of one or both signals.

Respiratory rate measurement: The device tracks breathing by detecting the expansion and contraction of the abdomen or chest using a stretchable band worn around the respondent’s torso.

Cardiac electrical activity measurement: The device monitors the heart’s electrical activity through disposable electrodes.

System for Measuring Heart Rate and Skin Conductance

The BIOPAC BioNomadix wireless module for photoplethysmography (PPG) and electrodermal activity (EDA/GSR) combines both measurements, as they are typically performed on the same part of the body and are often used simultaneously in various research studies.

Heart rate monitor (PPG): Using optical (plethysmographic) methods, the device measures changes in blood volume in the capillaries and records heart rate data.

Skin conductance monitor (EDA): The device tracks changes in skin conductivity caused by sweat gland activity (sweating), often used to assess emotional arousal or stress.

System for Measuring Electrical Activity of the Peripheral Nervous System and Muscles (EMG)

Electromyography (EMG) is the process of measuring and recording the electrical activity of skeletal muscles. The electromyograph detects electrical signals triggered by muscle cells when nerve impulses activate them. The device can collect data from two channels simultaneously and is often used in studies exploring facial muscle activation.

B-Alert X24: Integrated System for Measuring Brain Electrical Activity - Electroencephalograph (EEG)

The Electroencephalograph (EEG) measures the electrical activity of the brain by detecting and recording the electrical signals generated by neurons. The B-Alert X24 EEG monitors these signals across 20 channels, allowing for precise analysis of the activity in different brain regions. In the SEB Behavioural Laboratory, the B-Alert X24 can be used in combination with other BIOPAC physiological measurement devices.

SLEEP RESEARCH

The equipment used for sleep quality research allows us to collect data in a natural environment, as participants can use it practically anywhere.

Oura Ring

The Oura Ring monitors sleep quality and other bodily signals. It offers a wide range of highly accurate sensors for measuring movement, heart rate, and skin temperature variations. The rings sync with a mobile app, allowing both users and researchers to access the data.

MotionWatch 8

The MotionWatch 8 is a medical-grade wrist monitor designed to track sleep, circadian rhythms, and physical activity. It also includes a light sensor and a button for manually recording events.

Dreem Headband

The Dreem Headband is a dry EEG system that monitors brain activity, breathing, movement, and heart rate during sleep.

EXPERIMENT DESIGN AND EXECUTION

When measuring human responses in the Behavioural Lab, the timing and order of presenting experimental stimuli are crucial. The software dedicated to experiment design and execution allows us to capture data accurately and according to a precise timeline.

E-Prime and Chronos

E-Prime is software designed for planning and executing computer-based experiments, allowing researchers to easily create complex tasks and experiments while ensuring high accuracy in measuring and recording data.
Chronos is a powerful USB-based response and stimulus device that connects with E-Prime, enabling synchronized recording of timing data during experiments.
