Interactive Tactile Maps for Blind People using Smartphones Integrated Cameras
- Tactile maps may support blind persons in orientation and understanding geographical relations, but their availability is still very limited. However, recent technologies such as 3D printers allow to autonomously print individual tactile maps which can be linked with interactive applications. Besides geographical depictions, textual annotation of maps is crucial. However, this often adds much complexity to tactile maps. To limit tactile complexity, interactive approaches may help to complement maps by the auditive modality. The presented approach integrates barcodes into tactile maps to allow their detection by standard smartphones' cameras. Automatically, more detailed map data is obtained to auditively support the exploration of the tactile map. Our experimental implementation shows the principal feasibility and provides the basis of ongoing comprehensive user studies.
