pymovements.gaze.GazeDataFrame.pos2vel

GazeDataFrame.pos2vel(method: str = 'fivepoint', **kwargs: int | float | str) → None

Compute gaze velocity 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: fivepoint. (default: ‘fivepoint’)

• **kwargs (int | float | str) – 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.
