Abstract
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.
