A headset, a trace, and software that says which part of it is strange.
A brain-computer interface built with my school’s biotech academy. It reads brainwaves off a consumer headset, records a session, and flags the windows where activity runs unusually high or low.
The hard part was not the signal. It was deciding what counts as unusual, and then showing the operator the exact window the software is pointing at, so the judgement stays with the person.
