Abstract
Interactive evolutionary computation (EC) is
an effective method for reflecting user's favor to creation of media contents. In this research area, user's fatigue by selecting or evaluating contents remains as a problem. Takagi et al. proposed a framework of novel EC technique which uses user's physiological indices as evaluation value instead of subjective evaluation. In our previous study, we constructed EC system that creates musical melody based on evaluation of listener's heartbeat information, however, the system provided only simple melody. In this study, as an advanced system, we constructed an EC system that creates musical piece with code development which was used in Canon by Pachelbel. In the constructed system, user's heartbeat intervals during listening musical pieces were used for evaluation value in Genetic Algorithm. To investigate the effectiveness of the constructed system, subjects participated to two listening experiments; roulette selection and elitism strategy vs. random selection. Furthermore, some musical melodies were shown and compared.
