The objective of Caalyx-MV is to widely validate an innovative and efficient ICT-based solution focused on improving the quality of life of the elderly. This is to be achieved through prolonging the time they can safely remain autonomous and independent at home through monitoring and controlling their social and health status and by providing them with tools and services to support their daily home activities in terms of comfort, security, energy efficiency and communication. The CAALYX-MV system consists in a wearable light device able to measure specific vital signs of the elder, as well as to detect falls and to communicate autonomously in real time with his/her caregiver in case of an emergency, wherever they are. The emergency information can be directed to the personal caretaker and/or to the 112 Emergency Service. The emergency information will provide the geographic position and health information of the elder in a sensible way for the caretaker or emergency service. The incorporation of largely non-intrusive sensors for fall detection and geo-positioning is expected to address many of the concerns of the elderly about adopting technology. The system will be tested and validated in three pilot sites (in Spain, Italy and the Netherlands), and will obtain reliable assessment by gathering real end users' feedback. Finally, the pilots will demonstrate that CAALYX-MV can be easily integrated into the existing technological infrastructure of most European network operators - as well as into up and coming New Generation Networks - and of any home. The system will thus be ready for launch at pan-European level as soon as the project has been successfully validated.
