In South Korea more 1.38 million senior citizens live alone and few social workers are taking care of them (1 social worker for almost 27 senior). A survey shows that a majority of elderly living alone have a TV set. The first thing they do when they get up in the morning is turn on their TV. Thinking something can be done using TV, KT has developed a new service named “Life saving TV project”. Linked with the TV set, as soon as the TV is not active more than 24 hours, a sms is sent to the social worker to inform and alert and then the social worker call the senior to check everything is ok.
