A system, comprising: a head worn display configured to display symbology of an operating environment; a tracking camera; a tracking processing unit communicatively coupled to the tracking camera configured to: determine a position and orientation of the head worn display, transmit a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value; a controller communicatively coupled to the head worn display and the tracking camera comprising: one or more processors; and a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to: display the symbology on the head worn display; determine a quality-of-service value based on at least the signal quality value; characterised by modifying at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if the quality-of-service value changes from a high-quality value to a low-quality value. a head worn display configured to display symbology of an operating environment; a tracking camera; a tracking processing unit communicatively coupled to the tracking camera configured to: determine a position and orientation of the head worn display, transmit a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value; a controller communicatively coupled to the head worn display and the tracking camera comprising: one or more processors; and a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to: display the symbology on the head worn display; determine a quality-of-service value based on at least the signal quality value; characterised by modifying at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if the quality-of-service value changes from a high-quality value to a low-quality value. determine a position and orientation of the head worn display, transmit a position and orientation signal to a controller, wherein the position and orientation signal includes a signal quality value; a controller communicatively coupled to the head worn display and the tracking camera comprising: one or more processors; and a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to: display the symbology on the head worn display; determine a quality-of-service value based on at least the signal quality value; characterised by modifying at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if the quality-of-service value changes from a high-quality value to a low-quality value. one or more processors; and a memory with instructions stored upon, that when executed by the one or more processors, cause the one or more processors to: display the symbology on the head worn display; determine a quality-of-service value based on at least the signal quality value; characterised by modifying at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if the quality-of-service value changes from a high-quality value to a low-quality value. display the symbology on the head worn display; determine a quality-of-service value based on at least the signal quality value; characterised by modifying at least one symbol of the symbology based on the quality-of-service value from a default symbol to a degraded symbol if the quality-of-service value changes from a high-quality value to a low-quality value.
