A predictive speller for a Brain-Computer interface (BCI) based on Motor Imagery. The task is to write the sentence "what a wonderful day". BCI control is based on four imagined movements (left hand, right hand, both hands, feet). Imagined movements produce modifications on sensory-motor rhythms over the sensory-motor cortex. These modifications are detected in real time from the EEG signal and translated into commands for the spelling application. For details refer to http://www.slideshare.net/tizyweb/a-p...
