Keywords :

Human activity measurement, IoT-Internet of Things, information fusion, false positive management, uncertainty management

Application fields

  • Home care for people in vulnerable situations

    • home measurement of modalities related to the inhabitant fragility
    • Referal system for
      • the person itself
      • the family
      • caregivers
      • medical and welfare professionals
  • Technology parts :
    • Indoor location by non-supported and non-intrusive devices
    • Actimetry
    • Measurement of habits and change of habits


  • Integration of expert knowledge
  • Multi-modal, multi-source information fusion by IoT
  • Management of imperfect information: imprecise, uncertain, incomplete, contradictory
  • Decision support integrating the development of dashboards adapted to each user profile
  • Experimental validation
  • Privacy and health data regulation where applicable

Know-how involved in the project

  • Techniques for the identification of situations based on habitat measurements :
    • Information fusion and associated theories : possibility theory, probability theory, evidence theory .
    • Learning, representation, and use of high-level information
    • Uncertainty management, data incompleteness
  • Mastery of the main Machine Learning techniques of Artificial Intelligence and ability to select the one adapted to the application.
    • deep learning
    • data mining
    • supervised and unsupervised classification (FCM, KNN, Random Forest, SVM)
  • Rapid prototyping of sensitive objects embedding sensors and communicating objects. Mastery of embedded tools like nanocomputers and microcontrollers.
  • Rapid prototyping of applications for connected and intelligent objects.

Scientific problematics

  • Measurement of human activity (actimetry) from sensors preferably non-supported and non-intrusive.
  • Modeling and identification of human situations and activities, management of related imperfect information
  • Explicability : how to bring semantics and meaning to the measurement.


This project resulted in the production of an abstract habitat representation model that allows automatic identification of situations. This approach is being applied in the creation of an intelligent showroom.
