A conceptual update of affordance theory that introduces the mechanisms and conditions framework, providing a vocabulary and critical perspective. Technological affordances mediate between the features of a technology and the outcomes of engagement with that technology. The concept of affordances, which migrated from psychology to design with Donald Norman''s influential 1988 book, The mechanisms and conditions framework shifts the question from Putting the framework into action, Davis identifies existing methodological approaches that complement it, including critical technocultural discourse analysis (CTDA), app feature analysis, and adversarial design. In today''s rapidly changing sociotechnical landscape, the stakes of affordance analyses are high. Davis''s mechanisms and conditions framework offers a timely theoretical reboot, providing tools for the crucial tasks of both analysis and design.
