The Use of Smart Glasses for Lecture Comprehension by Deaf and Hard of Hearing Students AbstractDeaf and hard of hearing students must constantly switch between several visual sources to gather all necessary information during a classroom lecture (e.g., instructor, slides, sign language interpreter or captioning). Using smart glasses, this research tested a potential means to reduce the effects of visual field switches, proposing that consolidating sources into a single display may improve lecture comprehension. Results showed no statistically significant comprehension improvements with the glasses, but interviews indicated that participants found it easier to follow the lecture with glasses and saw the potential for them in the classroom. Future work highlights priorities for smart glasses consideration and new research directions.

Teachers of the visually impaired (TVIs) regularly present tactile materials (tactile graphics, 3D models, and real objects) to students with vision impairments. Researchers have been increasingly interested in designing tools to support the use of tactile materials, but we still lack an in-depth understanding of how tactile materials are created and used in practice today. To address this gap, we conducted interviews with 21 TVIs and a 3-week diary study with eight of them. We found that tactile materials were regularly used for academic as well as non-academic concepts like tactile literacy, motor ability, and spatial awareness. Real objects and 3D models served as “stepping stones” to tactile graphics and our participants preferred to teach with 3D models, despite finding them difficult to create, obtain, and modify. Use of certain materials also carried social implications; participants selected materials that fostered student independence and allow classroom inclusion. We contribute design considerations, encouraging future work on tactile materials to enable student and TVI co-creation, facilitate rapid prototyping, and promote movement and spatial awareness. To support future research in this area, our paper provides a fundamental understanding of current practices. We bridge these practices to established pedagogical approaches and highlight opportunities for growth regarding this important genre of educational materials.
