Abstract

A display system for displaying information to a vehicle operator comprises one or more projectors positioned in an operator cab of a vehicle. The projector is configured to project a heads up display of a plurality of data sets on a windscreen of the vehicle. Projected data sets are positioned in the heads up display and/or moved within the heads up display based on assessed relative priority levels of the data sets. Thus, for example, a data set with a higher assessed relative priority level may be positioned in a location of greater operator viewing prominence. If the priority level drops, the data set may be moved to a position of lower operator prominence. Respective heads up displays may be projected on more than two separate windscreens of the vehicle, either simultaneously or at alternate times, and possibly depending on an operational mode of the vehicle.
