From the concepts of "Universal Design" and "Wayfinding" it is conceived the proposal of the present work, which focuses on people with visual impairment and their way of communicating with the world. A common method of special communication for the visually impaired is the Braille alphabet, but it is known that it is possible to introduce proposals for tactile and auditory adaptation of visual contents to this audience according to the intended application. In order to facilitate the production of more technologically advanced objects and products for this
public, we have the tool of Digital fabrication.

This research was developed using as a reference projects already built that adopted this concept, and studies of pioneering research in this area. The objective was to investigate tactile map / model symbologies for the spatial orientation of visually impaired people using digital fabrication tools. It is expected that this research may contribute to the dissemination of the importance that the development of new reading instruments and tools for spatial orientation for visually impaired individuals.

Having the theoretical part already founded, and some practical methods already established, this work went ahead by proposing the elaboration of a tactile flowcharts, prototyped in 3D printer and lasercutter, then to try it as a methodology of participatory architectural design.
