A core set of five mouse trajectory prototypes including the 'straight' trajectory, the mildly curved trajectory, the continuous change-of-mind trajectory, the discrete change-of-mind trajectory, and the double discrete change-of-mind trajectory.
An object of class
array of dimension 5 x 100 x 2.
Mouse- and hand-trajectories often occur in types. In such cases, movement
trajectory data should be analyzed in terms of discrete type assignments
(Wulff et al., 2021). To this end mt_map can be used to map mouse- or
hand-trajectory to the closest of several predefined prototypes.
mt_prototypes provides a core set of prototypes that has been shown to
represent well a large fraction of empirical movement trajectories (Wulff et
To tailor the set of prototypes to a given study,
mt_prototypes can be
extended using mt_add_trajectory.
