摘要:
Deception can be evaluated by presenting a set of sentences or words to a testee, including some sentences or words that are expected to evoke significant pupil dilation in a testee who is lying and other sentences or words that are not expected to evoke significant pupil dilation in the testee. Changes in the testee's pupil size are compared to ascertain whether a pupil-dilation response to certain sentences or words is larger than for other sentences or words, and an indication of deceptiveness or non-deceptiveness is output based on the results of the ascertaining.

Systems and methods for detecting deceptive intent of a subject include observing eye movements of the subject and correlating the observed movements to known baseline neurophysiological indicators of deception. A detection system may record eye movement data from the subject, compare the eye movement data to a data model comprising threshold eye movement data samples, and from the comparison make a determination whether or not the subject is lying. The detection system may create an alert if deception is detected. The eye movements detected include saccadic and intersaccadic parameters such as intersaccadic drift velocity. Measurements may be collected in situ with a field testing device, such as a non-invasive, non-contact device attached to the subject's computing device and configured to non-obtrusively record the eye movement data.

An infrasonic stethoscope for monitoring physiological processes of a patient includes a microphone capable of detecting acoustic signals in the audible frequency bandwidth and in the infrasonic bandwidth (0.03 to 1000 Hertz), a body coupler attached to the body at a first opening in the microphone, a flexible tube attached to the body at a second opening in the microphone, and an earpiece attached to the flexible tube. The body coupler is capable of engagement with a patient to transmit sounds from the person, to the microphone and then to the earpiece.

This disclosure describes various systems for collecting thermal measurements of regions of a user's face. Each of the systems includes a frame configured to be worn on the user's head, and one or more lightweight thermal cameras that are coupled to the frame and configured to take thermal measurements of a region of interest on the user's face. Due to their coupling to the frame, the thermal cameras remain pointed at their respective regions of interest event when the user's head performs angular movements. The thermal measurements collected by some embodiments of the systems described herein may be utilized for a variety of applications that involve detecting different types of physiological responses or medical disorders.

The present invention provides a system and a method for eliciting information to sensitive questions and reliably detecting whether one is being deceptive, concealing information, or experiencing a heightened emotional response to the question. In particular, the system and the method of the invention are based on analyzing the user behavioral biometric of using one or more input device(s).
摘要:
This invention is a validation process for ipsative assessments. Respondents are connected to an Electroencephalograph (EEG) and some or all of the ipsative assessment questions are asked again while connected to the EEG. The EEG measuring frontal lobe responses in terms of gamma waves is compared with the assessment questions. Positive responses provide one frontal lobe response in terms of gamma waves, negative or false answers provide a different gamma response and neutral questions provide a neutral gamma response. Reading the responses then tells whether the respondent initially responded with integrity, if so the assessment is validated.
摘要:
Computer program product for processing GSR (galvanic skin response) signals, which when run on a computer controls the computer to estimate a level of arousal, or at least a change in the level of arousal, of a user, provided with an algorithm that is configured to control a computer to calculate a third or higher central moment of a recorded GSR signal and to derive an estimation of the level of arousal from said third or higher central moment.
摘要:
A computerized veracity testing system including a subject observation subsystem operative to provide an output representing at least one characteristic of a subject, the subject observation subsystem including a hand engagement unit including at least one physiological parameter sensor and having a selectable immobilizer for selectably immobilizing at least a portion of a hand of the subject and an automatically operable computerized analysis subsystem responsive to the output of the subject observation subsystem for providing an indication relevant to veracity of the subject.
