  Optional columns: Columns which can be automatically preprocessed if need be

  • position_z: For 3D positional data

  • position_(name)_(axis): Position columns can be automatically preprocessed and have distances etc. calculated if they follow given naming structure e.g. positions_vrhead_x

  • rotation_(name)_(axis): Rotation columns can be automatically preprocessed if then follow given naming structure

  Computed columns: These columns are computed automatically and ovewrite any existing columns of given names. Please don't namme your custom columns with these names

  • time_since_start

  • time_diff

  • distance

  • distance_total

  • speed

  • rotation_(name)_(axis)_diff

  Additional columns: the data fame can have unlimited number of additional columns, if they don't interfere with naming of the mandatory and optional (e.g. you shouldn't have a column named rotation_controller if you don't want it preprocessed by the package). Typical examples of additional columns can be "fps", "input" etc.
