Physiological-based Dynamic Difficulty Adaptation in a Theragame for Children with Cerebral Palsy

The purpose of this research is to provide a physiological-based Dynamic Difficulty Adaptation (DDA) able to be used in a CVA rehabilitation application, and more especially in the Children Rehabilitation Project (CRP). The CRP is an adaptive modular interface destined to CVA’s rehabilitation, and has for purpose to offer a state-of-the-art rehabilitation platform to improve CVA’s rehabilitation through rehabilitation applications. In the report, we go through all the steps of this research, by going through (1) the state of the art done on DDA and on physiological-based DDA, (2) the approach based on the emotional state, (3) the acquisition of physiological signals, (4) the extraction of the physiological signals’ features and (5) the training of a learning algorithm able to dynamically change the difficulty. While we successfully managed to implement a physiological-based DDA based on Anxiety and Boredom emotional state (in order to be able to use the flow theory) in the CRP, we still need to experiment it on children in CVA’s rehabilitation.
