Toward a Real-Time Index of Pupillary Activity as an Indicator of Cognitive Load

The Low/High Index of Pupillary Activity (LHIPA), an eye-tracked measure pupil diameter oscillation, is redesigned and implemented to function in real-time. novel Real-time IPA (RIPA) shown discriminate cognitive load re-streamed data from earlier experiments. Rationale for the RIPA tied functioning human autonomic nervous system yielding a hybrid based on ratio frequencies oscillation. paper's contribution drawn provision documentation calculation RIPA. As with LHIPA, it possible researchers apply this metric their own experiments where interest.
