HaptOSM
• HaptOSM ⇒ Haptic Open Street Map• Command-line Java Software• Converting OSM-data into G-Code• Takes several map-based parameters (Center, Scale,etc.)
• Modified CNC-Router embosses Braille paper

Detailed feedback
• Test persons confirm high usability• Expect significant personal advantage• Preference to writing film due to stronger embossing• Although would prefer Braille paper → more naturalfeel
• Missing shops and public authorities• Map best readable when put on flat surface
