The base for the WalkersGuide project was the diploma thesis with the title " "Navigationssystem für blinde Fußgänger und ÖPNV-Nutzer" ("Navigation system for blind walkers and public transportation users"). It was completed at the TU Dresden, faculty of computer science in march 2014.
The thesis starts with a state of the art chapter, which lists current navigation aids for the blind and also covers some related research projects. After that follows a list of user requirements. The main part contains a concept for such a navigation system, based on the priorly defined user requirements. One of the concept's key components is the integration of the public transportation system into the route calculation process. After a chapter about the prototypal implementation follows an evaluation of the created navigation system.
