Telefónica Móviles and ONCE (the Spanish Organisation for Blind People) have just launched a mobile phone for blind people. The device, that has no display, sends audio warning about the presence of messages, incoming or lost calls. It also gives information about the battery, time, network, etc.
The general outlay as well as the keybord were designed to be used also by people who have limited hand mobility.
