  "Description": "A modular and extendable approach to extract\n(micro)saccades from gaze samples via an ensemble of methods.\nAlthough there is an agreement about a general definition of a\nsaccade, the more specific details are harder to agree upon.\nTherefore, there are numerous algorithms that extract saccades\nbased on various heuristics, which differ in the assumptions\nabout velocity, acceleration, etc. The package uses three\nmethods (Engbert and Kliegl (2003)\n<doi:10.1016/S0042-6989(03)00084-1>, Otero-Millan et al.\n(2014)<doi:10.1167/14.2.18>, and Nyström and Holmqvist (2010)\n<doi:10.3758/BRM.42.1.188>) to label individual samples and\nthen applies a majority vote approach to identify saccades. The\npackage includes three methods but can be extended via custom\nfunctions. It also uses a modular approach to compute velocity\nand acceleration from noisy samples. Finally, you can obtain\nmethods votes per gaze sample instead of saccades.",
