pymovements.gaze.gaze_dataframe.GazeDataFrame.pos2vel#

GazeDataFrame.pos2vel(method: str = 'smooth', **kwargs) → None[source]#

Compute gaze velocites in dva/s 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:

  • method (str) – Computation method. See pos2vel() for details, default: smooth.

  • **kwargs – Additional keyword arguments to be passed to the pos2vel() method.

Raises:

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