Ensuring fair treatment and equal opportunity for all groups when applying technology.

A state characterized by reduced cognitive efficiency, attention, and alertness, often resulting from prolonged activity or attention.

Signals to user or system indicating excess cognitive load, fatigue, or reduced attention, which may require rest.

Using extracted features to classify or decode the user's intent. It is typically the next step after feature extraction, using algorithms to categorize features into meaningful classes for BCI applications.

The process of identifying and isolating relevant signals from brain activity data, transforming raw signals into a reduced set of features of interest.

Automatic extraction of distinctive patterns from complex neural data.

Choosing the most informative signal features to enhance classifier performance.

A distributed learning approach that allows collaborative training without sharing raw brain data.

Continuous comparison of the output from performing a task with its desired output

A signal processing tool used to enhance the quality of the recorded brain signals. Filters work by allowing certain frequencies to pass through while reducing or eliminating others.

Application of digital or analog filters to remove unwanted components or noise from brain signals.

A mathematical measure used to describe the complexity or self-similarity of EEG or physiological signals.

Transforming time-domain signals into the frequency domain to analyse the signals' characteristics at different frequencies.

Features based on the power or distribution of the signal across different frequency bands.

Statistical dependencies (e.g., PLV, coherence) between brain regions.

Technique using electrical pulses to stimulate muscles, often controlled by BCI for rehabilitation tasks.

A magnetic resonance imaging technique on the brain that registers blood flow to functioning areas of the brain, based on the principle that active areas consume more oxygen.

An optical brain monitoring technique that uses near-infrared light for the purpose of functional neuroimaging, by measuring hemoglobin concentration changes associated with neural activity.

Assurance that the BCI systems and its associated procedures function correctly, reliably, and predictably.

Ultrasound-based technique to map brain activity via cerebral blood volume changes with high spatiotemporal resolution.
