From alarm systems to smart houses

The percentage of senior citizens in the Netherlands will rise in coming years. The expected percentage for the year 2010 of persons over age 65 in the total population is 15%. More persons over age 65 than ever before will continue to live in their own environment. Emergency response systems (ERS) can support independent living. The most common type of organization distributing ERS is a small, partly subsidized local alarm organization run by a social welfare office for the elderly. Government subsidy has been reduced in recent years which has motivated small organizations to join together into larger regional organizations in order to get a more solid financial base. On the other hand new semi-commercial and commercial organizations have come into being. These developments are part of the growing importance of home care, leading to more medical applications of ERS. User satisfaction with ERS is high. Portable triggers can enhance the effectiveness of the system. However, many users do not wear the portable trigger when feeling well. Future technical developments will result in multifunctionality of ERS-devices. In the long term the hardware of today will be integrated in a multimedia home terminal replacing the telephone. The portable trigger will remain the only specific hardware at home for ERS.
