As with the guide-post reference frame, this reference frame also involves an external secondary reference object. In this type of reference frame, the secondary reference object is an animate entity, whose location serves as a frame of reference in locating the relevant part of the primary reference object enabling the figure to be located. For instance, in the following example: The grocery store is to the right of the office building, the speaker 'projects' his or her bodily horizontal asymmetry (left/right axis) onto the primary reference object (the office building) in order to locate the figure (the grocery store). It is because the speaker projects axial properties onto the reference object in this way that this reference frame is referred to as projector-based.
