Abstract

Responses of a human subject may be by voice, hand or foot movement, or bodily secretions, as examples. A hiatus of such responses may be termed a lapse in the continuity of the response, including a hesitation pause in the voice, a movement of hand or foot on a monitored control of a motor vehicle or vehicle simulator, or pulsatile bodily secretions on a monitored control of an implantable insulin pump. In a voice response, the hesitation pause may be more than about one second in the voice of a subject during a dialogue or monologue. The hiatus rate of such responses is indicated by the present apparatus, as is the average hiatus duration for two or more hiatus rates. The dominant hiatus rate is also determined and indicated. A microprocessor is utilized in such determination. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.
