This interdisciplinary project integrates expertise from law and ethics into research on the design, regulation, and deployment of systems that ensure perspicuity, thereby enabling effective human oversight and control to mitigate risks. By examining both run-time and inspection-time scenarios, the project analyzes the interplay between technical, legal, and ethical perspectives. The goal is to develop interdisciplinary best-practice guidelines that shape the scientific agenda of the Transregional Collaborative Research Centre 248, Foundations of Perspicuous Software Systems, and to inform future policy-making in the domain of perspicuity.
