Questions people actually ask

The eye tracker is a high-definition infrared camera mounted with the testing station. It records involuntary ocular-motor signals—such as pupil changes, blink patterns, gaze fixations, and related reading/response behaviors—while you answer true/false (or yes/no) questions on the computer. Those measurements, along with your responses, are analyzed by Converus software to produce a credibility score. The tracker is non-contact: nothing is placed on or in your eyes.

No. The eye tracker uses infrared optical sensing designed for nonintrusive monitoring. It does not shine harmful lasers into the eyes, does not require drops, and does not touch your eyes. Most people describe the process as simply sitting at a computer and answering questions. If you have an acute eye injury, recent eye surgery, or a condition that makes screen use difficult, tell us before the appointment so we can advise on suitability.

The laptop (or station computer) is the heart of the EyeDetect Station. It presents the standardized test questions, records your answers, receives data from the eye tracker (and, for EyeDetect+, from physiological sensors), and runs the automated analysis that produces your credibility outcome. Using a computer ensures every examinee receives the same fair protocol and that scoring is objective and consistent.

Traditional polygraph and EyeDetect measure different signals and excel in different situations. Peer-reviewed and manufacturer-reported research shows EyeDetect is highly competitive with polygraph for many screening and investigative uses, and it is often faster, more standardized, and less invasive. EyeDetect+ combines ocular-motor data with physiological channels similar to polygraph in an automated workflow. In some programs, EyeDetect is used as a first-stage screen and polygraph for deeper follow-up; when methods agree, confidence in the outcome can be substantially higher. We help you choose the right tool for your question.

Feeling nervous before a credibility test is normal—and expected. Protocols are designed around patterns associated with deception-related cognitive load, not ordinary anxiety alone. Being calm helps you read and respond clearly, but nervousness by itself is not the same as a “fail.” We walk you through the process, answer questions beforehand, and create a professional, low-pressure environment. If you have a diagnosed anxiety condition or panic history, mention it when you schedule so we can prepare appropriately.

A major advantage of EyeDetect and EyeDetect+ is computer-administered testing and algorithmic scoring. The examiner’s personal feelings do not “grade” your eye data the way a purely subjective interview might. Everyone receives the same standardized question presentation and scoring model. Our role is to set up the station correctly, ensure you understand instructions, maintain a professional environment, and deliver results with integrity—regardless of gender, background, or who requested the exam.

Many people with common vision conditions (including astigmatism) can still complete ocular-motor testing successfully, especially if they can see the screen well enough to read and respond. Glasses can sometimes interfere with infrared tracking because of reflections; contacts are often preferred if you normally use them. Significant eye disease, recent surgery, or conditions that prevent reliable tracking may require evaluation or an alternative protocol. Disclose vision issues when booking—we will advise honestly if EyeDetect is appropriate or if another approach is better.

In most cases you should continue prescribed medications as directed by your physician—do not stop medication without medical advice just for a test. However, substances that strongly affect reaction time, eye movement, or pupil response can influence data quality. Please provide a list of medications (and any recent recreational drug or heavy alcohol use) when you schedule. We follow Converus guidance and will tell you if anything is likely to compromise the exam. Do not use pupil-dilating or constricting eye drops as a “trick”—abnormal pupil behavior is detectable and can invalidate a test.

Understanding the questions is essential for a valid exam. Deception Detection can administer tests in over 40 languages. Tell us your preferred language when you book. If you become confused during pretest instruction, say so immediately—we will clarify or reschedule with the correct language support rather than push forward on a test you cannot fairly understand.

We only share results with parties who are authorized for that exam. In private fidelity matters, authorization and release terms are set at intake—often the person who scheduled and paid, or as both parties agree in writing. We will not casually disclose your results to a spouse, partner, employer, or anyone else without the proper authorization. If you are the examinee, ask us to explain exactly who will receive the report before you begin.

Instructions and practice/orientation happen before the scored portion so you know what to expect. Once the automated test is running, interrupting can affect data quality. If something urgent happens (equipment issue, illness, inability to see the screen), alert the proctor immediately using the procedure we explain at the start. Non-urgent questions are best asked before the scored sequence begins or after it ends.

Please use the restroom before the scored exam begins. Mid-test interruptions are discouraged because continuous, standardized data collection matters for validity. If you have a medical need that may require a break, tell us during scheduling or pretest so we can plan the session appropriately.

EyeDetect protocols present questions in a timed, computer-controlled format so everyone is tested consistently. The system is built around response patterns under that standard timing—not an open-ended essay. During pretest we make sure you understand how to answer (typically true/false or yes/no with the mouse). If reading speed, language, or vision makes the format unfair for you, tell us before scoring starts; we may adjust language, discuss suitability, or recommend a different protocol rather than force a poor-fit exam.

Traditional polygraph remains a core second-stage tool. After a multi-issue screen (or an EyeDetect screen), examiners may administer a single-issue / event-specific polygraph on the topic that needs resolution. That second hurdle uses the classic instrument channels—heart/blood-pressure related signals, respiration, and electrodermal activity—under validated question formats. Industry pre-employment guidance has long described multi-issue screen → specific-issue polygraph as proper successive-hurdles practice when time and budget allow.

Successive hurdles works best when stages are independent—they measure different things. Polygraph targets autonomic physiology; EyeDetect targets ocular-motor and reading/response patterns linked to cognitive load. Converus notes that independence is why EyeDetect + polygraph can be modeled for higher combined outcome confidence (often discussed in the mid-to-high 90% range when both agree), whereas two successive polygraphs do not create the same independence argument. We can design either classic polygraph-only hurdles or EyeDetect-then-polygraph programs for your case.
