Abstract: Abstract Online whiteboards leverage our spatial thinking abilities to support rich, collaborative, and interactive design. However, these tools are often exclusionary to people who are blind. We ran a series of user studies with university students to better understand the accessibility of current tools and evaluated several existing audio and haptic approaches to inform design guidelines and future directions. We observed how current interfaces do not provide access to the graph generation process, provide incomplete access connections and spatial relationships, and can lead to users feeling uncertain or misinterpreting information in the graph. By exploring existing solutions, we identify and discuss the importance of reflecting the diagram structure within the navigation scheme and provide a spatial overview whereby users can reference their exploration. We summarize a series of recommendations to inform the investigation of future interactions to improve the accessibility of online whiteboards.
