Cimahi Cyber - It is often said that people who lie can not help but just give instructions through his eyes , the UK Daily Mail wrote in its report .
Now scientists are developing a lie detector that can tell whether someone is telling the truth to monitor the movements of their eyes.
The researchers used eye- movement tracking
technology to pioneer a promising alternative to the traditional polygraph lie detector .
Using eye movements to detect lies, works differently than conventional polygraph test . Instead of measuring one's emotional reaction to lie, eye movement- tracking technology to measure cognitive reaction to someone.
To do so , researchers note the number of measurement while the subjects answered a series of questions with right or wrong answer on the computer. Measurements include pupil dilation , response time , reading and rereading time , and errors.
The researchers stressed that lying requires more effort than telling the truth , so they look for indications that the subjects are working hard.
For example , someone who is not honest will widen the pupils and take some time to read and answer questions.
These reactions often occur and require accurate measurement and modeling to determine statistical significance.
In addition to measuring various types of response, eye- tracking methods to detect lies has several other benefits in addition to polygraph .
" eye tracking method to detect lies has great potential , " Gerald Sanders , one of the venture capitalists who have licensed the technology from the University of Utah .
" It's a matter of national security that our government agencies have the best and most sophisticated method to detect truth from fiction , and we believe we need a license to handle special research conducted at the University of Utah . "
Tracking eye movements to detect deceit become possible in recent years due to the substantial increase in technology. The Utah researchers said that they were the first to develop and evaluate software and methods for applying this test effectively.
Eye- tracking promising substantial cost savings , requiring a fifth of the time required for testing , and available in multiple languages.
