It seems to me that HMI "metaphors" can take the form of arrows, needles, and/or moving tapes pointing in an intuitive directions (that one might expect in other real-world situations) and auditory cues that come from the right direction. Also the order in which information is provided to the operator can ³metaphorically² represent the operatorıs cognitive model of how pipes are arranged or valves are located in a processing plant for example.
