What is Fitting and Rehabilitation

This chapter focuses on the framework of non-deterministic Brain Computer Interfaces within the context of Human Computer Interaction. A very special subgroup of these interfaces, emerging from the world of hearing loss, comprises the Cochlear Implants that affirmatively expose direct manipulation techniques. Short and long memory experiments with musical exploitation can prove shortcomings in inner-knowledge handling and provide understanding of how the language mechanism provides steady, un-biased speech. A model and a protocol for parameterizing sustainable aural communication skills are presented.
