Brain Computer Interface-based Multimedia Controller

Music is a way of expressing our feelings and emotions in daily life. Suitable music can affect people in a positive way. However, current multimedia control methods, such as manual selection or automatic random mechanism which is now applied broadly in MP3 and CD player, cannot adaptively select suitable music according to the user´s state. In this study, we proposed a novel brain computer interface (BCI)-based multimedia controller to help people to select suitable music according their cognitive states. In our system, a multimedia control MIDlet program built in the mobile phone was developed to recognize the user´s cognitive state and select suitable music according his/her cognitive state. A wireless multi-channel electroencephalograph (EEG) acquisition module was also designed for monitoring the user´s EEG. By the property of selecting suitable music type according to the user´s cognitive state, our BCI-based mobile multimedia controller provides a novel prototype of multimedia controller.
