Digital map to guide for blinds

Modern cities surrounded by mega structures have become so complex where even normal visitors feel estranged and get lost in the maddening lanes, and not to talk about visitors with low or no vision. Providing a solution, German designer Rob has come up with a digital street map named the “plan.b” that provides a tactile representation of surroundings to the visually impaired, navigating them safely in puzzling lanes.
The digital map not only let the user feel the surface to sense the information of the surroundings, but offers additional audio information by pressing the displayed structures as well. Providing all important information on proportions of architecture and distances, the plan.b enables the visually impaired move independently, freely and safely, no matter if he or she is familiar with the locality or not.
