An apparatus and a method for automatically determining the present will of a human subject. The characteristic values of the subject are detected and output signals corresponding to the detected characteristic values are produced, amplified and digitized. A set of state variables for each selected frequency sub-band of a selected frequency band for each of the output signals is determined. Sets of reference weights and sets of reference biases for a neural network from sets of state reference variables corresponding to known wills are formed. Each of the sets of state variables, the sets of reference weights and the sets of reference biases are applied to the neural network to determine present will of the subject. The present will of the subject can be displayed or used to control an external device, such as a robot.

1. Apparatus for automatically determining a present will of a human subject, comprising:a plurality of sensors which detect at least one member of the group consisting of scalp potential at a plurality of points on a scalp of said subject, muscle potential at a plurality of points on a body of said subject, heart rate of said subject, eye movements of said subject, and eye blinks of said subject, and produce output signals for detecting characteristic values of said subject when affixed to a body of said subject; amplifiers for amplifying said output signals; and a processor for: digitizing said output signals, determining a set of state variables for each of a plurality of selected frequency sub-bands of a selected frequency band for each of said output signals, storing sets of reference weights and sets of reference biases for a neural network, wherein each of said sets of reference weights and each of said sets of reference biases is formed from a set of state reference variables corresponding to a known will, and applying each of said sets of state variables, said sets of reference weights and said sets of reference biases to said neural network to determine said present will of said subject.
