Eye-tracking data

This dataset contains detailed eye-tracking data recorded by a Dikablis Glasses 3 eye tracker. The column names follow a clear structure, typically in the format of Device_DataType_Source_Eye_SpecificMetric. The data includes timestamps, fundamental pupil information, an index of cognitive activity, and eye movement events (fixations and saccades), with independent measurements provided for the left and right eyes. In analysis, we only care for pupil data.Here is a detailed explanation of each column:General and Time Informationrec_time: Recording Time. This represents a timestamp from the start of the recording, likely in milliseconds or seconds.UTC: Coordinated Universal Time. This provides an absolute time reference for the recording.Gaze DataDikablis Glasses 3_Eye Data_Original_Pupil X: Gaze Point X Coordinate. This likely represents the horizontal position of the gaze point, calculated from a fusion of both eyes, within the scene camera's field of view.Dikablis Glasses 3_Eye Data_Original_Pupil Y: Gaze Point Y Coordinate. This represents the vertical position of the gaze point within the scene camera's field of view.Detailed Left Eye DataPupil Metrics..._Left Eye_Pupil X / ..._Left Eye_Pupil Y: Left eye pupil's center coordinates (X and Y position) within the frame of reference of the eye camera...._Left Eye_Pupil Area: The area of the left pupil. This is a key metric for analyzing cognitive load and emotional arousal...._Left Eye_Pupil Height / ..._Left Eye_Pupil Width: The height and width dimensions of the left pupil.Index of Cognitive Activity..._Left Eye_Index Of Cognitive Activity Average: The averaged Index of Cognitive Activity. This is a metric calculated by the Dikablis software, likely a smoothed or averaged value of the raw index, used to measure cognitive load...._Left Eye_Index Of Cognitive Activity Sample: The sample Index of Cognitive Activity. This represents the raw index value at each individual sampling point.Fixation Data..._Left Eye_Fixations_Fixations: Left eye fixation events. This could be an ID for each fixation or an event marker...._Left Eye_Fixations_Fixations Duration: The duration of each individual fixation event for the left eye.Saccade Data..._Left Eye_Saccades_Saccades: Left eye saccade events. This could be an ID for each saccade or an event marker...._Left Eye_Saccades_Saccades Duration: The duration of each individual saccade event for the left eye...._Left Eye_Saccades_Saccades Angle: The angle or direction of the saccade made by the left eye.Detailed Right Eye DataThe data columns for the right eye mirror those provided for the left eye, offering the same set of comprehensive measurements. This includes:Pupil Metrics: Pupil X, Pupil Y, Pupil Area, Pupil Height, Pupil WidthIndex of Cognitive Activity: Index Of Cognitive Activity Average, Index Of Cognitive Activity SampleFixation Data: Fixations, Fixations DurationSaccade Data: Saccades, Saccades Duration, Saccades Angle
