“…As Reising (1999) has pointed out, there is an important difference between a full work domain analysis and the kind of AH analyses we used to generate sensorannotated AHs for Pasteurizer II. A work domain analysis for pasteurization would model the economic as well as engineering context of use of a pasteurization plant (Rasmussen et al, 1994).…”

In this paper we use sensor-annotated abstraction hierarchies (Reising & Sanderson, 1996, 2002a to show that unless appropriately instrumented, configural displays designed according to the principles of ecological interface design (EID) might be vulnerable to misinterpretation when sensors become unreliable or are unavailable. Building on foundations established in Reising and Sanderson (2002a) we use a pasteurization process control example to show how sensor-annotated AHs help the analyst determine the impact of different instrumentation engineering policies on a configural display that is part of an ecological interface. Our analyses suggest that configural displays showing higher-order properties of a system are especially vulnerable under some conservative instrumentation configurations. However, sensor-annotated AHs can be used to indicate where corrective instrumentation might be placed. We argue that if EID is to be effectively employed in the design of displays for complex systems, then the information needs of the human operator need to be considered while instrumentation requirements are being formulated. Rasmussen's abstraction hierarchy}and particularly its extension to the analysis of information captured by sensors and derived from sensors}may therefore be a useful adjunct to up-stream instrumentation design. #

In this paper we establish a foundation for understanding the instrumentation needs of complex dynamic systems if ecological interface design (EID)-based interfaces are to be robust in the face of instrumentation failures. EID-based interfaces often include configural displays which reveal the higher-order properties of complex systems. However, concerns have been expressed that such displays might be misleading when instrumentation is unreliable or unavailable. Rasmussen's abstraction hierarchy (AH) formalism can be extended to include representations of sensors near the functions or properties about which they provide information, resulting in what we call a ''sensorannotated abstraction hierarchy''. Sensor-annotated AHs help the analyst determine the impact of different instrumentation engineering policies on higher-order system information by showing how the data provided from individual sensors propagates within and across levels of abstraction in the AH. The use of sensor-annotated AHs with a configural display is illustrated with a simple water reservoir example. We argue that if EID is to be effectively employed in the design of interfaces for complex systems, then the information needs of the human operator need to be considered at the earliest stages of system development while instrumentation requirements are being formulated. In this way, Rasmussen's AH promotes a formative approach to instrumentation engineering.# 2002 Elsevier Science Ltd.

This limiting feature is not always given the emphasis it deserves. [. . .] A measuring instrument which indicated directly and accurately its position relative to the earth's surface would render obsolete the entire science of navigation as we know it. This illustrates clearly the limits imposed on navigation systems by lack of a sensing instrument. The whole system of celestial and radio fixes, the use of compass information, inertial and other ''dead reckoning'' systems, are all substitutes for what we would like to sense directly and display but do not yet have the sensing means for. The initial step in considering the design of the displays for a particular manual control system is to analyze the information the operator would really like to have and to consider the sensing instruments available to obtain it for him. Too often this analysis is not carried out, and it is assumed that the operator requires information that, for instance, has been displayed on similar systems in the past . . .
