Abstract

A communication system for patients with severe verbal and motor disorders and total paralysis is described. Patients first learn voluntary control of an intact muscle or an electric brain response in an operant "biofeedback" learning procedure. Secondly, they select by using the learned response letters from a Language Support Program (LSP) which are presented in a hierarchical structure of a decision tree starting with selection of groups of letters and narrowing it down to the selection of one single letter. Dependent upon the precision of the execution of the learned response and the signal threshold for that motor or electrocortical response, two types of errors are possible: missing the correct symbol (Type I) or choosing the wrong one (Type II). The description of a spelling interface LSP, symbol structures, criteria for the evaluation of LSP and optimal LSP types are illustrated with simulated data and data from a typical patient.
