I studied electrical engineering. After getting blind I quickly noticed there are some sort of tactile graphics, but their use is very limited. I thought especially there should be a way to use tactile graphics for schematics and diagrams at work.
I found some devices and got them funded via the German work agency. But a lot of stuff is missing. Tactile Graphics libraries, Software to easily generate tactile graphics as a blind person, … I created a lot of things and some software you can buy on this website.
