The effectiveness of an interactive audio‐tactile map for the process of cognitive mapping and recall among people with visual impairments

Abstract

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 semi‐structured interviews were conducted to examine their views surrounding the study and the product. Results The experimental condition had significantly better overall recall than the control group and higher average scores in all four areas examined by the questions. The interviews suggested that the interactive component offered individuals the freedom to learn the map in several ways and did not restrict them to a sequential and linear approach to learning. Conclusion Assistive technology can reduce challenges faced by people with visual impairments, and the flexible learning approach offered by the audio‐tactile map may be of particular value. Future researchers and assistive technology developers may wish to explore this further.

The Effectiveness of an Interactive Digital Map for Visually Impaired People

“…This study refers to the research of [8], by reviewing the effectiveness of an existing interactive digital map for people with visual impairment while learning a new environment or surroundings [11]. This study consisted of an experimental group that followed a series of tests related to understanding spatial literacy.…”

Assessment of the Circulation Impact of Furniture in Industrial Buildings through Space Syntax

“…It involves recognizing shapes, distances, directions, remembering spatial layouts, manipulating mental images, and finding routes to different locations (Emelin & Tkhostov, 2018). This cognitive ability is essential for tasks like reading maps, routing, and solving spatial problems (Griffin et al, 2020), and it holds particular significance in fields such as architecture, engineering, urban planning, and transportation (Ma, 2022). Awareness of spatial cognition allows architects and engineers to optimize spatial layouts for utilization, workflow, and safety (Hajji, 2019).…”
