London: Now, you can easily spot if someone
is lying to you, with the help of a computer, say scientists.
A team at the University of Buffalo has developed a new
software that focuses solely on the subject`s eyes, monitoring
the movements of the pupils, which determines if someone is
telling you the truth or lying.
For their study, the scientists recorded a series
conversations in which a number of lies were told. And having
tested their program against a trained human interrogator,
they found that the software had a higher success rate.
While the specially trained examiner correctly identify
65 per cent of false statements, the computer recorded an
impressive 82.5 per cent reading.
"What we wanted to understand was whether there are
signal changes emitted by people when they are lying, and can
machines detect them?" a newspaper quoted Prof Ifeoma
Nwogu as saying.
In fact, the study centred around conversations in which
subjects could chose whether or not to steal a cheque, before
later being questioned on their decision.
A wide range of individuals were selected, with varying
skin colours, age and height with someone even wearing glasses
in an attempt to conceal their lies.
Despite most of those interviewed being caught out, there
were a select number who managed to keep their eye movements
to a bare minimum, which consequently resulted in the wrong
Now, the scientists plan to carry out additional studies
on a larger scale with a long-term view to developing a system
that could work alongside human interrogators.
