Iran builds URL device for blind people

Iranian researchers designed a URL device to be placed in public places, including subways to help blind people find their ways.
The URL device is made up of two hardware and software parts. Its hardware, used by blind people, has been established and the software is installed on blind people's cell phone, the Iranian students' news agency reported.
The hardware and cell phone are attached via Bluetooth. When the blind user activates the software in his cell phone he is informed via an alarm when he is 50 meters of the device. The user then presses Select Button and hears the name of the place through his cell phone.
Then he presses Option Button in his cell phone and a light music is played in the intended site, helping the blind person find the place without getting help from others.
The URL device is to be utilized in certain subway stations in Tehran.
