Compute a transparent pupil activity index
Usage
pupil_activity_index(
y,
time_ms = seq_along(y),
sampling_rate_hz = NULL,
method = c("velocity", "frequency_contrast", "ripa_proxy"),
low_band = c(0.05, 0.5),
high_band = c(0.5, 4),
fast_window_ms = 250,
slow_window_ms = 750
)
Arguments
- y
Pupil signal.
- time_ms
Time vector.
- sampling_rate_hz
Sampling rate for frequency methods.
- method
`velocity`, `frequency_contrast`, or `ripa_proxy`.
- low_band, high_band
Frequency bands for frequency contrast.
- fast_window_ms, slow_window_ms
Smoothing windows for the RIPA-style proxy.
Value
A numeric value or vector containing a transparent pupil activity index.
