The Preliminary Lie Detector Glasses (PLDG) will be an innovative way to determine, at a most basic essence, whether a conversational partner is lying. Produced in the form of an inconspicuous pair of glasses, two high-tech cameras will be concealed within both the nose bridge and right hinge of the glasses.

Each camera will speedily analyze the other person’s eyes. It is known that when lying, pupils typically dilate and eyes look to the left. The cameras, with their enhanced automatic zooming feature, will send visual input to a mini computer contained within the glasses’ right temple to calculate these factors using an advanced algorithm. Additionally, the number of times the other person’s eyes deviate from their subject (break eye contact) will be quantified and compared to data from their pupil and eye movement. These calculations will take only a few seconds, depending on positioning between the conversationalists.

Overall, the algorithm will determine whether the person appears to be lying, and if so, a small red light will appear on the inside of the frame, visible only to the wearer. From there, the wearer will be informed of possible untruths, and will be able to pay more attention to the words of the person they are conversing with. The information provided by the PLDG is not intended to incriminate anyone, and cannot be used as evidence against others. The results, are, as stated, preliminary, implying that the assumption of lying is to be used to alert the wearer to observe the person they are conversing with more closely. The wearer of the PLDG can dismiss the information collected and given by pressing a small button on the left temple of the glasses.

With this technology, people can become more aware of the people they speak with, enhancing business deals and relationships.
