Identification of variation in mental strain of an agricultural tractor operator in the field during precise fertilizer spreading

The article describes the possibilities of spatial identification of the level of brain activity of the operator of modern agricultural machinery, where control procedures have become largely automated. The operator operates a computerized interface to program the operation of the machine, whose geographical position within the field is monitored by GPS. Using the Muse 2 brain activity measuring armband, the operator's performance was monitored during the execution of control activities by assigning geographic coordinates and the machine's operating status to each event. This made it possible to identify places within the field where the operator's brain activity was high and places where attention levels were low. Linking the level of brain activity to the machine's operating data made it possible to generate maps of the spatial variation of the level of operator attention brain activity in relation to the aforementioned machine data.
