  12. 12. Lumpur Smart environments – Ambient Intelligence  An AmI system requires the use of distributed sensors and actuators to create a pervasive technological layer, able to interact transparently with a user, either passively by observing and trying to interpret what the user actions and intentions are, but also actively, by learning the preferences of the user and adapting the system parameters to improve the quality of life and work of the occupant (Remagnino et al, 2005)

  17. 17. Lumpur Ambient Assisted Living  Application of the AmI paradigm to promote and prolong independent living for older and disabled people, and their families “There is no reason for older people in Europe to miss out on the benefits of new technologies. The solutions and services resulting from this programme will help them to remain active in society as well as staying socially connected and independent for a longer time” Viviane Reding, former EU Commissioner for the Information Society and Media

  54. 54. Current work
  55. 55. Lumpur Monitoring people at home  Activities that can be detected:  Recognition of activities of daily living (ADL): wake-up, going to the toilet, sleeping…  Activity level: light, moderate, intensive  Location and tracking of the person inside the home  Risky situations: fall detection, dangerous objects; fire, flood, gas alarms…  Social activity: leaving home, receiving visits, use of telephone…  Detection of basic and advanced activities: cooking, watching TV…  Person-environment interaction
  56. 56. Lumpur Monitoring people at home  These systems are composed of multi-sensor networks to extract knowledge in order to:  Detect anomalous behaviours  Launch alarms to caregivers (professionals or informal carers)  Current ambient assisted spaces make use of a collection of simpler sensors that try to get information from the environment  However, this information is incomprehensible to a caregiver
  57. 57. Lumpur Monitoring people at home  Computer vision is essential for surveillance and safety tasks  Visual information is commonly the most natural way of describing an event, a person, an object, actions and interactions  But, not only for the detection of activities. Also to give the possibility of watching the assisted person at their home in order to ensure that they are alright and whether or not they need help
  58. 58. Lumpur Privacy preservation  Appropriate measures need to be considered to preserve dignity and maintain privacy and confidentiality  We are working with different types of cameras: omni-directional, stereo, infrared, kinect  Establishing a compromise between activity to be recognised and privacy required
