All digital systems that interact with the environment, the assisted person and all those around him pose at least three types of problems that need addressing: Acceptability, Ethics, Security.
Ethics and security are are besides treated, we shall thus focus on what the acceptability imposes on the interactions between the man and the machine. The acceptability in the long term can only be done if the assisted person is at least in the system: reliability, usefulness, affordance, plasticity interfaces, multi-modality. The need for reliability and usefulness is obvious, against other dimensions justify a small development.
This dimension aims at the integration of technical features required in operational computer equipment. This research is based on the design and evaluation of prototypes. Indeed, the mechanisms designed to fulfill the needs of a given population are systematically entrusted to persons (real "samples" of the target population) who are experiencing life-size the deployed service.
The support of the dependent people can be largely improved thanks to technical helps. Among these, the environmental control allows the housing to provide support services to the user by exploiting the multi-source measures (home automation, multimedia, electrical signatures, etc.) from sensors placed in the environment and detect the activity of the inhabitants. A data mining process can identify behavioral patterns such services frequently, regularly or rarely used. The identification of uses scenarios will improve the quality of service and human security.
Other research themes emerged during the various HAAL seminars:
