VR-centred-I-DT-algorithm
In I-DT_alg_VR_centred.py can be found a Python code that defines the I-DT algorithm for a VR centred system. The input of the algorithm is a Dataframe with seven columns: One is the time; three are the position of the gaze; three are the position of the subject's head. The algorithm returns the same Dataframe with an additional binary column named "class_disp". If it is a zero the frame belongs to a fixation; if it is a one the frame belongs to a saccade.
This algorithm is part of a publication.
