The main objective of this proposal is the development and integration of innovative technologies for the detection of abnormal events (such as falls) or unexpected behaviours that may be related to a health problem in elderly people.With the proposed approach, the elderly will gain confidence and independence. CONFIDENCE will be a cost effective, non-intrusive and reliable system that will increase the quality of life and security of the elderly and, thus, prolong their personal autonomy and participation in society. Hence, CONFIDENCE directly addresses the objective ICT-2007.7.1. ICT and Ageing. Not only will the elderly profit from the system, but also their families and caregivers, since the burden on them will be substantially reduced. CONFIDENCE will decrease the need of institutionalisation of the elderly and, thus, there will be a significant cut down in healthcare expenditure.The fear or result of fall accounts for 40% of the nursing home admissions. Moreover, the fear of falling decreases quality of life and increases the decline in the ability to perform daily activities. These effects are measured using the Fall Efficacy Scale (FES).The project aims to achieve a value above 50 in the FES, which represents a fair confidence level in daily activities.CONFIDENCE will work both outdoors and indoors. The user will wear a few tags, whose positions are determined using radio technology. The tags' coordinates will be used to reconstruct the user's posture. This information, together with some environment information, will be analysed to decide whether to trigger an alarm. The system will be easy to setup and to use and will not constrain the user's daily life.The result of this multidisciplinary research will be a working prototype. The end-user will be involved in the RTD activities by co-defining the specifications, monitoring and testing the project. Psychological, ethical and legal surveillance activities will be carried out throughout the project.
