Brain–computer interfaces: read the loop, not the headline
Understand BCI research through its measurement, decoding, feedback, and user-control loop—not a promise of mind reading.

BCI Wearable Neuro Browser
A careful guide to evaluating wearable signal claims, consent, measurement context, and the difference between sensing and a usable interface.
TOPIC GUIDE / 06 · READ, QUESTION, EXPLORE
Name the signal and the output
Ask what a wearable measures and how that measurement becomes the claimed output. Do not assume that a device using the word neuro is a brain–computer interface or a clinical assessment tool. Record the actual task, validation evidence, and limits described by the provider or study. Avoid interpreting a proprietary score as a direct measure of a person’s thoughts or abilities.
Include the person in the review
Consider setup, comfort, consent, the ability to stop, and the handling of recorded signals. A laboratory demonstration may involve support that a casual description leaves out. Before considering a device for health-related use, seek appropriately qualified advice. This website does not sell, ship, pair with, or endorse BCI wearables.
Three questions to take with you
01What does the sensor actually measure?
02How was the claimed output evaluated?
03Can the person stop recording and control reuse?
