Eye Tracking Data
The eye tracking data is divided into three distinct parts: 'Left,' 'Right,' and 'Center.' 'Left' tracks the participant's left eye movements, 'Right' tracks the participant's right eye movements and 'Center' represents the mean of the 'Left' and 'Right' eye data, estimating global participant eye movements.
Each eye (Left, Right, and Center) tracks the same data points and has the same data columns. This means you will always find three columns corresponding to each data point in the outputted data table. For example, the table will always include Eye_Center_Origin_X, Eye_Left_Origin_X, and Eye_Right_Origin_X or Eye_Center_HitTexture, Eye_Left_HitTexture, Eye_Right_HitTexture etc. To avoid redundancy in the data explanation table below, we have created a generalized format using a placeholder ([eye]) instead of writing out each eye (Left, Right, and Center).
The data in the outputted CSV file is organized as follows: the 'Center' eye appears first, followed by the 'Left' eye and then the 'Right' eye.ParticipantEyesData.csv, making it easier to understand what each column is tracking. Explore the table below for detailed information on each column's data type and format, as well as an example data and a short description.
