Edlund, Carl, Hume, Sam and Lewis, Michael (1995): Ecological Design for a Network Scheduling Interface. In: Proceedings of the Human Factors and Ergonomics Society 39th Annual Meeting 1995. pp. 501-505.

“A motivation in the design of Ecological Interfaces for process control is to augment the strengths of the human operator with the strengths of the automation in the computer system. This is especially important when building interfaces for managing the use of Wide Area Networks (WANs) in enterprise computing. This domain requires network operators to be able to control the allocation of resources and to monitor the occurrence of structural and functional failures. The relationship between the network architecture, infrastructure, traffic characteristics, and pricing scheme is dynamic and highly inter-related. A "Tetris-like", bin-packing interface is designed based on principles drawn from an ecological user model and a situation theoretic representation of the problem space and the user's task. The effectiveness of this display is based on a number of ecological features whose design is automatically generated through the determination and selection of the interface context.”

Edlund, Carl and Lewis, Michael (1994): Comparing Ecologically Constrained and Conventional Displays in Control of a Simple Steam Plant. In: Proceedings of the Human Factors and Ergonomics Society 38th Annual Meeting 1994. pp. 486-490.

“Graphical User Interfaces (GUIs) are becoming increasingly common for application software in process control. Conventional interfaces display the states of a system without conveying the constraints which drastically reduce the evolutions which must be considered. Our model resolves this difficulty by presenting system parameters in the context of ecological constraints mirroring those of the underlying process. A simulation of a simple steam plant with five different GUIs was used. The displays were a conventional Dials display, a Mimic display, an Object display, a Seesaw analogue, and a Fluid-tank analogue. Poor over-all performance in maintaining specified values was found for the Seesaw and the Object displays. The Dials and the Mimic displays performed similarly but with greater accuracy. The best control was observed in the experimental Fluid-Tanks display. These Findings are consistent with our hypotheses.”
