Lie detector glasses tell you if someone is telling the truth

'The use of this technology in criminal investigations is astounding,' said Winscher, who has over 31 years of law enforcement experience, including 25 years teaching interrogation and using the polygraph and other voice analysis technologies. 'Not only can you analyse 'live' conversations, but you can do a deep analysis of the interview, or do off-line analysis of recorded conversations. This enables law enforcement to focus on areas that require further investigation, saving a great deal of time.'

V's Gatekeeper Security product, GK-1, uses LVA technology to provide an easy-to-use way of clearing people through security checkpoints in less than 30 seconds.

Gatekeeper uses the responses to five 'yes or no' pre-scripted questions to provide real-time analysis and signal 'Green' for cleared, or 'Red' for the need for further questioning. The use of LVA technology in V's Gatekeeper Security product is significant because it provides objective risk assessment.

In an airport or other security setting, LVA provides an accurate and unbiased means of quantifying risk, avoiding both profiling and the wasted resources involved in random searches.
