Abstract
Disclosed are techniques for displaying AR elements on a display system of a construction machine. A position of the construction machine in a world reference frame is detected. An orientation of the construction machine is detected. A position of an operator of the construction machine in a machine reference frame is detected. A position of the operator in the world reference frame is determined based on the position of the operator in the machine reference frame, the position of the construction machine in the world reference frame, and the orientation of the construction machine. The AR elements are generated based on the position of the operator in the world reference frame and a position of the display system in the world reference frame. The AR elements are then displayed on the display system.
