Fuzzy Evaluation Method of DPDFS for Unity Game Based Brain Training toward Prevention of AD

The proportion of Alzheimer's disease (AD) has been increasing fast in recent years, and game based brain training is helpful to prevent Alzheimer's disease and early treatment. But it is hard to evaluate the result of brain training. Therefore, the research group designed a brain health exercise game based on Unity, and proposed a fuzzy scoring of evaluation method based on difference value of progress degree corresponding to different steps, named DPDFS. The model was tested through the scores of 30 consecutive games of 120 participants aged from 22 to 29. The results show that the model is very suitable for new hand in games, and it also verifies the effectiveness of games on brain training.
