Text-Guided Image-to-Image Translation for Converting RGB Maps to Tactile Images
Tactile graphics provide blind and visually impaired individuals access to visual information through touch, aiding navigation, education, and social interaction. However, manual tactile design is costly, time-intensive, and difficult to scale. This thesis proposes a novel approach to generate …

Indoor wayfinding in children with visual impairments: How the use of a coding robot impacted route familiarization and spatial planning
… the route multiple times, verbal directions, and tactile maps—work well for many, but not all. When one student struggled to learn a route in his high school using traditional methods, coding a robot to replicate the pattern of his route was the teaching method that finally worked for him. …
