Background People with visual impairments can experience numerous challenges navigating unfamiliar environments. Systems that operate as prenavigation tools can assist such individuals. This mixed‐methods study examined the effectiveness of an interactive audio‐tactile map tool on the process of cognitive mapping and recall, among people who were blind or had visual impairments. The tool was developed with the involvement of visually impaired individuals who additionally provided further feedback throughout this research. Methods A mixed‐methods experimental design was employed. Fourteen participants were allocated to either an experimental group who were exposed to an audio‐tactile map, or a control group exposed to a verbally annotated tactile map. After five minutes’ exposure, multiple‐choice questions examined participants’ recall of the spatial and navigational content. Subsequent …
