title: [Basis for information transmission with biosignals for development of technical communication aids for handicapped patients].
abstract: For the design of communication aids controlled by biosignals for the handicapped, an analysis of the aspects of the significance of information is mandatory. The definition of information in its five aspects statistics, syntax, semantics, pragmatics and apobetics, enables us to conclude that the transmission of information is possible only with voluntarily influenceable biosignal components. The voluntary influencing of the biosignal may be interpreted as a modulation of the amplitude density of the Fourier integral. By calculating the highest possible statistical information content of a biosignal, it is possible to estimate the technical complexity of a biosignal-based communication system. The construction of efficient communication aids is possible when many biosignal components that can be readily and rapidly controlled voluntarily are to be found.
