The foundation 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.

The document is only available in German and can be downloaded here: PDF and BibTeX.

New features:

Additional changes

The structure of the app has also changed. The “Favorites” tab has been replaced by the “Overview” tab. Your existing favorites were transferred to a collection and can now be found in the overview tab under the pinned profiles section.

The tab bar at the bottom of the screen is now permanently visible, allowing for easier switching between the main views of the app.

Some tabs now have their own tab bar. If available, this is located in the top area of the screen. For example, the “Overview” tab has two sub-tabs called “Pin” and “Track”. The newly named “Routes” tab, next to it, is divided into the sub-tabs “Navigate” and “Record”.

You can also quickly access all sub-tabs from other parts of the app. To do this, focus on the corresponding tab at the bottom of the screen and perform a long click or swipe through the Talkback actions.
