The SENSACTION-AAL project aimed to assist older adults in maintaining independent mobility and reducing fall injuries through physical activity interventions using wearable sensors. It developed three main applications: a virtual trainer for home rehabilitation exercises providing audio feedback, a smart monitor for tracking daily mobility, and a remote assistant for detecting falls and alerting caregivers. An initial clinical trial with 18 older adults found the system feasible and that it increased adherence to exercises, awareness, and reduced falls. However, further validation is still needed including improved methods for simulating falls versus detecting real falls.

5. 3 Application Scenarios Local (e.g. home rehabilitation and training, QoL assessment for user-awareness, short-term , real-time , etc.) Remote (e.g. providing awereness of patient state after treatment to caregivers, long term analysis of behaviour, off-line ) Local and Remote (fast reactive detection of dangerous events, alarm dispatching to user and caregivers)

12. 3-Fall documentation 25 reported falls  19 verified falls in 6 subjects Clear differences emerge between real and simulated falls!

13. Management of falls SensAction-AAL Tele-Care Scenario : Accelerometer data are real-time processed by PDA application. An alarm is sent from PDA to the web server in case of fall to advise caregiver (SMS, e-mail) for starting appropriate actions .
