Abstract

An event-based bio-signal capturing system is disclosed. At least one bio-signal capturing device captures a bio-signal measured from biological beings; and at least one event capturing device captures an event and generates a corresponding event marker. A data recording device acquires the bio-signal and the event marker, wherein the bio-signal and the event marker are acquired with corresponding time reference for subsequent event-based data analysis.
