Combine wireless sensor network and multimedia technologies for cognitive function assessment

The purpose of this study is to use wireless sensing technologies to develop a cognitive function analysis system based on Montreal Cognitive Assessment (MoCA). The system consists of three parts: (1) Data acquisition: We have designed seven kinds of games to assess five-oriented capabilities including naming, attention, abstraction, delayed recall and orientation. System collects automatically all operation steps, error count and finish time when tester plays the game. (2) Data analysis: try to analyze the collected data and calculate the quantitative results of mental indicators. (3) Feedback system: to screen the high-risk group of degradation of cognitive function to start the care plan earlier. This system can not only assist long-term care institutions to create new social activities for elder person, but also train their cognitive abilities and reduce the risk of dementia.
