Catching The Right Bus - Improvement Of Vehicle Communication With Bluetooth Low Energy For Visually Impaired And Blind People

Visually impaired and blind people have major difficulties in locating and communicating with public transport vehicles due to their restriction of vision. They must rely on other people's help or technical supports. In this paper we show how direct communication with the bus driver via Bluetooth Low Energy (BLE) is possible. A person with visual restriction is able to send and receive messages via an accessible smart-phone app directly to the bus driver. With the help of the suggested system traveling with public transport gets easier and the person's independent mobility is improved.
