Summary¶

Representation design concerns how displays and interfaces present information so that operators can perceive and act on the meaning of a work domain, not merely its surface features (Flach et al., 2021). The chapter situates this within cognitive systems engineering (CSE), which shifts the focus from human-computer interaction to human-work interaction and from information processing to meaning processing. It organises design around different types of constraint — process, agency, and surface constraints — that shape human experience and performance.

Body¶

Context¶

Flach et al. (2021), in their handbook chapter on representation design, examine how displays and interfaces should present information so that operators perceive and act on the meaning of a work domain rather than its surface features. They situate this within cognitive systems engineering (CSE), which shifts the focus from human-computer interaction to human-work interaction and from information processing to meaning processing, and organise design around different types of constraint. Within this knowledge base the article is the meaning-centred counterpart to the cognitive-foundations work in Information Processing and Sensation And Perception: where those treat the operator's internal limits, representation design treats the display surface that those limits act on, and it connects to Situation Awareness (which the chapter cites as a target for representation) and to the broader design-and-evaluation strand in Usability And User Experience.

Key Points¶

Representation design builds on a foundational insight about error and design. Flach et al. open with Fitts and Jones's (1947) evaluation of aircraft displays and controls, which concluded that many errors attributed to human operators were actually the result of poor design and could have been anticipated had human performance been considered more carefully. More than seven decades later that conclusion is beyond doubt, but technology and how people interact with it have changed dramatically, moving beyond the mechanical displays and perceptual-motor concerns of Fitts and Jones's era (PDF pp. 1–2, orig. pp. 947–948).

The chapter advances a shift from information processing to meaning processing. In studying the problem solving required for supervisory control and fault diagnosis, researchers moved attention from the information-processing limitations of people to the meaning-processing capabilities of experts. CSE accordingly shifted the focus from human-computer to human-work interaction, and from task analysis to a broader construct of the work domain. The most significant change was recognising the need to tune operators' situation awareness and mental models to the deep structure of the processes being controlled (Flach & Voorhorst, 2020, cited in Flach et al., 2021) (PDF p. 2, orig. p. 948).

Constraints are the organising concept for design. Flach et al. frame representation design around constraints that affect human experience: process constraints in the work domain itself, agency constraints relating to the actors, and surface constraints relating to the interface. Good representation design makes the relevant work-domain constraints perceptible at the interface surface, so that meaning is available to perception rather than requiring effortful inference (PDF pp. 6–7, orig. pp. 952–953).

The chapter integrates several design traditions — human factors, user interface design, cognitive systems engineering, and user experience design — as related conversations about the constraints that shape performance (PDF p. 2, orig. p. 948). Abstraction hierarchy analysis and ecological interface design appear as methods for surfacing work-domain structure in the representation (PDF pp. 7–8, orig. pp. 953–954).

Conclusion¶

Flach et al. (2021) conclude that representation design is a meaning-centred complement to information-processing accounts of perception and cognition: by making work-domain constraints perceptible at the surface, displays let operators act on what a situation means rather than infer it, extending Fitts and Jones's original lesson that good design anticipates human performance.

Open Questions¶

How can abstraction hierarchy analysis be applied to interfaces for highly automated and AI-mediated work domains?
When does designing for meaning processing conflict with designing for information-processing efficiency?
