  • Publication number: 20040143170
    Abstract: A psychophysiological signal processing system uses mental and physical activity to determine the intent of an examinee to conceal information or deceive an examiner or trained observer. Brainwaves; eye, heart, muscle, and/or speech activity; skin conductance, resistance, and/or impedance; body temperature, position, posture, expression, and/or gestured motion; blood flow and volume; and stress-indicating measures like respiration, blood pressure, heart rate, and/or other such phenomena that can be sensed from the body may be utilized. A computer-adaptive system analyzing one or more of these psychometric data may be used in combination with a virtual reality system presenting stimuli to the examinee to enhance existing polygraph methods used for individual screening, debriefing, identification and/or certification of information, interrogation, and/or the detection of deception.

  • Patent number: 6708051
    Abstract: An apparatus for monitoring an electrophysiological signal within a magnetically sensitive apparatus comprises a stretchable elastic cap having a plurality of electrode holders designed to be filled with a conductive electrolyte. Electrodes are disposed within the electrode holders and leads extend from the electrodes. The electrodes and the leads are made of a non-ferromagnetic conductive material.

  • Publication number: 20020077534
    Abstract: A hands-free human-machine interface uses body position, limb motion, speech signals, and/or changes in the operator's level of cognition and/or stress to control the user interface of an interactive system. Signals are acquired from mental and/or physical processes, such as brainwaves, eye, heart, and muscle activities, larynx activity, body position and motion changes, and stress indicating measures. The signals are measured and processed to replace a hand-operated mouse, keypad, joystick, video game, or other controls with a motion-based gestural interface that works, optionally in conjunction with a larynx activated speech processor. For disabled individuals without sufficient dexterity and speech capacity, multimodal neuroanalysis will reveal intended movements and these will be used to operate an imagined mouse or keypad.
