Lie detector glasses tell you if someone is telling the truth

While the traditional polygraph is based on subjective analysis and uses physiological responses to determine if a person is telling the truth, LVA employs objective means and uses psychological responses. 'LVA far surpasses existing voice stress analysis technology by identifying the "why" behind a response,' said Richard Parton, CEO of V.

'It's not what you say, but how you say it. This is crucial, for example, in an airport setting where factors such as fear of flying, or concern about missing a plane may result in high stress levels without any improper intent.'

LVA is the main investigative focus tool designed for law enforcement, homeland security, intelligence, and armed forces professionals. This product operates in online, offline, and interrogation modes so users can focus their investigations sooner and don't waste time or resources chasing the wrong leads or the wrong suspect.

Online mode works spontaneously'without a predefined script, purpose, or pre-planned questions. The feedback indicates the cause of each 'problem' response'stress, excitement, confusion, inaccuracy, etc.'enabling investigators to tailor questions and follow leads as they develop.

Offline mode gives investigators a more efficient, accurate way to analyze pre-recorded (.wav) files, conversations, interviews or interrogations. Offline uses more vocal patterns to provide a much deeper analysis. LVA then generates a complete profile and report summarizing the overall emotional behaviour of the subject during the session.

Interrogation mode, developed with aid of internationally accredited polygraph experts, is designed to use the same sentence structures of questioning and psychological environment as a polygraph exam.

Polygraph operators can use this mode to screen a wide range of suspects and narrow the field down to a few for further evaluation. It also provides clear results necessary for use in employment screenings, suspect questioning, or verifying facts in a yes/no manner.

Already in use by some American law enforcement agencies, the new software is being met with approval. Waupun Wisconsin Police Chief Tom Winscher is using V's LVA technology.
