In investigations, the question of whether a person recognizes a crime scene, a weapon, a victim, or a co-conspirator is crucial. Investigators need a faster, more objective way to triage suspects, prioritize leads, and support decisions.
EyeTrek works alongside existing investigative workflows, not as a replacement for them.
EyeTrek presents the subject with structured visual and text-based stimuli — images of people, locations, objects, or documents — and measures their involuntary gaze response. A person who recognizes something they claim not to know will respond differently than someone with no prior knowledge. That difference is measurable and difficult to suppress.
As a result, investigators can detect recognition of crime scenes, weapons, victims, or co-conspirators, reveal familiarity during lineups, complement existing interview workflows and help prioritize suspects.
In addition to concealed knowledge detection, EyeTrek can evaluate responses to direct screening questions such as “have you ever?”.
