pymovements.gaze.GazeDataFrame.pos2acc#

GazeDataFrame.pos2acc(*, degree: int = 2, window_length: int = 7, padding: str | float | int | None = 'nearest') → None#

Compute gaze acceleration in dva/s^2 from dva position coordinates.

This method requires a properly initialized experiment attribute.

After success, the gaze dataframe is extended by the resulting velocity columns.

Parameters:

degree (int) – The degree of the polynomial to use. (default: 2)
window_length (int) – The window size to use. (default: 7)
padding (str | float | int | None) – The padding method to use. See savitzky_golay for details. (default: ‘nearest’)

Raises:

AttributeError – If gaze is None or there are no gaze dataframes present in the gaze attribute, or if experiment is None.
