SemAssist : assistance and assessment tools for semantic memory rehabilitation
Résumé
Semantic memory, which is responsible for the acquisition and maintenance of knowledge, plays an essential role in most cognitive functions and thus in activities of daily living (ADL). One rehabilitation approach, with patients presenting semantic memory deficits, is to help them maintain their residual knowledge or relearn lost knowledge through the execution and repetition of ADLs. During a therapy session, a caregiver supervises and assists a patient performing a predefined ADL. But this rehabilitation process is difficult to put into practice outside therapy sessions and data are lacking to assess patient progress with respect to everyday routine. SemAssist is a cognitive assistance system implemented to fill this gap. On the one hand, SemAssist guides the patient through the steps of a predefined ADL at home, providing semantic information about objects involved in this ADL. SemAssist records interactions with the patient, providing ecological data on the rehabilitation process
