I've been watching Peter König's research on this topic for some time. I was notified via email this morning that they are working to finally productize it:
"This is Susan Wache writing to you from the feelSpace project.
I received your e-mail from Prof. Peter König because you were interested in our experiments with tactile belts and to participate as a subject.
Our project has developed further. Apart from scientific research with the compass belt, we are now also well on our way to provide a commercial version of the tactile belt, including compass functionalities and navigation functionality, effectively guiding you via vibrations directly to any location you want to go to.
A lot of positive feedback from our subjects, blind and non-blind, but also my own enthusiasm after wearing the belt for over 6 months lead to the next step: In November 2015, my two colleagues Silke Kaercher, Jessika Schwandt and I founded a startup: the feelSpace GmbH.
We are close to a first product version of our tactile belt, targeting especially but not exclusively blind people, and thus are running a crowdfunding campaign on indiegogo:
