Smart Glasses for CVI: Co-Designing Extended Reality Solutions to Support Environmental Perception by People with Cerebral Visual Impairment. Kane S, Shinohara K. Assets 2025 Proceedings of the 27th International ACM Sigaccess Conference on Computers and Accessibility. New York, United States. Association for Computing Machinery.979-8-4007-0676-9https://mro.massey.ac.nz/handle/10179/74010Cerebral Visual Impairment (CVI) is the set to be the leading cause of vision impairment, yet remains underrepresented in assistive technology research. Unlike ocular conditions, CVI affects higher-order visual processing - impacting object recognition, facial perception, and attention in complex environments. This paper presents a co-design study with two adults with CVI investigating how smart glasses, i.e. head-mounted extended reality displays, can support understanding and interaction with the immediate environment. Guided by the Double Diamond design framework, we conducted a two-week diary study, two ideation workshops, and ten iterative development sessions using the Apple Vision Pro. Our findings demonstrate that smart glasses can meaningfully address key challenges in locating objects, reading text, recognising people, engaging in conversations, and managing sensory stress. With the rapid advancement of smart glasses and increasing recognition of CVI as a distinct form of vision impairment, this research addresses a timely and under-explored intersection of technology and need.CC BY 4.0(c) 2025 The Author/shttps://creativecommons.org/licenses/by/4.0/cerebral visual impairmentassistive technologyco-design, double diamondextended realityaugmented realityapple vision proconference10.1145/3663547.3746383c-conference-paper-in-proceedings
