Visually impaired persons (VIPs) often rely heavily on the use of assistive as well as mainstream technologies for accomplishing everyday tasks. The latter, especially when featuring artificial intelligence (AI), offer new possibilities for VIPs. This chapter explores how VIPs, via accounts, ascriptions, and engaging in category-bound activities, accept and reject membership of inference-rich categories, make relevant their level of vision and construct locally relevant identities as competent tech-users in the face of tech-related troubles when setting up or using mainstream AI technologies. In this way, the chapter contributes both to EM/CA research in how VIPs approach mainstream technology and how excuses are produced, including how certain membership categories are used by participants as a resource for exoneration from responsibility, and to the growing body of EM/CA studies of Human Computer Interaction.
