---- PROTOTYPE --------- PURPOSE: To design a prototype of an electronic refreshable map of the urban environment for individuals who are blind or have low vision. A German designer has developed plan.b, a digital street map projected onto a refreshable tactile display to provide a tactile representation of surroundings to the visually impaired to aid a person to navigate safely. It also offers additional audio information by pressing the displayed structures as well. The plan.b provides important information on proportions of architecture and distances, facilitating independent movement regardless of whether the user is familiar with the locality.
