Eye signals are simple to obtain, respond quickly to stress and cognitive load (lying), and cannot be controlled or manipulated. Therefore, they could be a great lie and deception indicator.

Eye-Minder's technology was developed based on these solid scientific findings by a multidisciplinary expert team with a proven track record.


Eye signals are complex signals. Thus, extracting and using the required information from them is a significant challenge. We managed to crack this challenge based on an innovative approach and years of experience.
