Risk Perception in Ecological Information Systems

Research output: Chapter in Book/Conference proceedings/Edited volumeConference contributionScientificpeer-review


One issue that regularly occurs in the context of ecological information systems is that these systems can invite operators to migrate to the limits of system performance. This could lead to the assumption that ecological systems are thus inherently unsafe. We argue, however, that the source of this issue is tied to a modeling problem of the work domain. That is, the majority of ecological systems predominantly model the physical or causa] structure of the work domain, thereby neglecting the intentional structure. Many complex socio-technica! systems contain a mix of causa] and intentional constraints-rules, procedures, and regulations-that contribute to safe operations of those systems. The work described in this chapter examines how visualizing intentional information in an ecological synthetic vision display affects pilot behavior, decision making, and safety in a terrain avoidance task. An experiment with 16 professional pilots showed that adding an intentional constraint increased the clearance during terrain avoidance and gave them more insight into the terrain avoidance task, which enabled them to make better tradeoffs between safety and performance.
