Once the sensors were placed on the Pasteurizer II sensor AH, whether in the minimally or maximally adequate sensor configuration, the sensor AH indicated the information to be collected and the derivations to be performed in order to build the ecological interface. The sensor AH also showed how the effects of failures would propagate.
Chi-square statistics could not be performed on these data because of the nonindependence of observations across cells, but the results suggest that EID.max participants made greater use (14 mentions) of the configural displays included in the ecological interface than did EID.min participants (7 mentions).
Overall, the ecological interface combined more- and less-successful properties (see Reising & Sanderson, 2002a, for further details).
Fourth, we have tested our hypotheses with just one ecological interface and one general class of instrumentation inadequacy.
In trying to move design--and ecological interface design in particular--from art to engineering practice, we are trying to reduce the amount of sheer invention involved in favor of either adapting proven existing designs or even borrowing proven existing designs from a compendium of solutions.
Not all variables will be shown on the eventual mimic display in the ecological interface, however; many are reserved for other configural displays within the ecological interface.
In the following sections we describe the development of the various displays in the Pasteurizer II ecological interface. We have provided most details for the energy display because it was pivotal to the ecological interface and because its development entrained the structure and detail of the other displays.
Figure 4 is a depiction of the final ecological interface. At top left is the goals display, which represented functional purpose.
