Smart-city projects promise to enhance the quality of life for the visually impaired, with Poland's Virtual Warsaw initiative a case in point. The city has established a network of beacon sensors to help visually impaired with independent navigation, fitted to edifices and transmitting data in real time to users' phones through Bluetooth.
Meanwhile, Dubai last year conducted the pilot of an iPhone app that can convert written information in metro stations as audio instructions, helping users go from entrance to ticket machine, gate, platform, and railway car.
Smart cities also can help arriving travelers navigate public spaces, and implementing better connectivity for smartphones is a solid beginning. More innovative technologies could include automated data points, with tactile maps or audio systems describing surroundings, enhanced by camera-directed image recognition that enables object identification/description.
