Small towns in Italy are building electronic navigation systems to help blind people or out-of-town tourists know where they are.
Since the fall of 2007, the EU Citizens Rescue and Protection Center (ISPC) in Ispra, Italy, began to implant 1,260 electronic tags on the sidewalks of Laveno Mombello in northern Italy and connect them to the SESAMONET network.
An antenna on the top of the blind cane activates it to pass through an RFID chip, which transmits a unique tag number to the smartphone he carries with him via radio frequency signals. The smartphone is equipped with a database of navigation information that maps the tag’s number to its current location. Through the Bluetooth headset on the mobile phone, the blind person will receive specific information about the location and the surrounding environment.
The road, filled with RFID chips, is 2 kilometers long. As the network continues to expand, residents can also be prompted with alternative roads and even lead them to prescribed destinations. Since the map stored in the smartphone needs to be updated from a central database, the operator can send information that changes at any time to identify unexpected obstacles such as a building.
The EU IPSC initially decided to launch the pilot to find a way to recycle RFID tags used in EU slaughtered livestock. With the success of the pilot, IPSC will expand the network to commercial buildings, providing services and room location information.
