How University Disability Services Professionals Write Image Descriptions for HCI Figures Using Generative AI
TL;DR
Findings show that alt text written solely by DSO professionals has lower quality than alt text written with AI assistance, while AI assistance also helped DSO professionals write alt text more quickly and with greater confidence; however, they reported inefficacy in interactions with the AI.
Abstract
Disability Services Office (DSO) professionals at higher education institutions write alt text for visual content. However, due to the complexity of visual content, such as HCI figures in research publications, DSO professionals can struggle to write high-quality alt text if they lack subject expertise. Generative AI has shown potential for understanding figures and writing descriptions, yet its support for DSO professionals remains underexplored, and few studies evaluate the quality of AI-assisted alt text. In this work, we conducted two studies: first, we investigated generative AI support for writing alt text for HCI figures with 12 DSO professionals. Second, we recruited 11 HCI experts to evaluate the alt text written by DSO professionals. Findings show that alt text written solely by DSO professionals has lower quality than alt text written with AI assistance. AI assistance also helped DSO professionals write alt text more quickly and with greater confidence; however, they reported inefficacy in interactions with the AI. Our work contributes to research on AI support for non-subject-expert accessibility professionals.
