An Information Delivery System on Disaster for Hearing-Impaired People Using LED Display – To Extend to Universal Use –
There is a sudden blackout on the big disaster. Under such circumstances, people get information verbally by voice, megaphone, and radio instead of looking at screen on PC smartphone, or TV by their eyes. After the big disasters, people have to find a safe place using voice announcements. However, hearing-impaired people cannot get information from voice announcements. Also, it is difficult to distinguish hearing-impaired people from others by their appearances. Therefore, they have little chance to be supported by others. We have researched and created a system for hearing-impaired people get information on the disaster using an LED display. Also, we found such a system is useful for elders and foreigners, too. People cannot use their smartphones as usual because of a shortage of their battery under disinters. Our system was designed to save battery using Bluetooth Low Energy (BLE) and small CPU. Besides, people will co-operate, looking at the same screen under the disaster situation.
