Frequently Asked Questions

RealEye studies are proven to be around 110 px accurate. This allows analyzing users interaction on a website with precision reaching the size of a single button.
We predict the gaze point with frequency up to 60 Hz.

For in-depth analysis of webcam eye-tracking accuracy check the following articles:

Webcam eye-tracking is an innovative method that predicts a person's gaze point.
We use the computing power of regular PC/laptop to run AI (Deep neural network) that analyzes images coming from a webcam. The AI detects panelist's face, pupils and predicts a gaze point.
All of this is performed entirely in a web browser in real-time. Thanks to this, panelists do not have to worry about their privacy. We do not send any image or sound to our servers. We only store the gaze point predictions from our AI, in the form of basic text data similar to "Timestamp: 10, GazePointX: 200, GazePointY: 330".

You can read more about eye-tracking here .

Either your own participants or RealEye testers. You can invite your users or panel and share the study with them using a participation link. All they need to have is a laptop/PC with a webcam.

We also have a network of panelists from all around the world - mainly from the UK and the US. Randomly picked users can be assigned to your task. They are called RealEye testers. We will not show them your stimuli before the test starts, so their interaction will be natural.

Your own participant is any person that you’ll invite using a participation link to your study. RealEye tester is a randomly picked person from our network of panelists from all around the world - mainly from the UK and the US. They can be hired to participate in the eye-tracking study, but not to participate in any external tool (eg. survey).

You can get additional participants at any time you need it. This will increase your limit in the current billing period only. Each additional slot for a tester (any tester) costs $1. Hiring Realeye testers is only $5 each.

When you order RealEye panelists, we make sure to provide the highest quality results. All recordings are checked by us to make sure that you get results with an accuracy of fewer than 175 pixels and at least a 20 Hz sampling rate. Assuring high-quality results usually requires us to pay for and check more panelists than you've requested, but we take that cost on us - so you pay only for the best results.

RealEye is tested and works with the following hardware and software setup:
  • Google Chrome or Edge (10) web browser,
  • PC/Laptop with Microsoft Windows 10 or Mac (Macbook, iMac) with MacOS,
  • a laptop integrated webcam or USB webcam,
  • RealEye DOES NOT allow running eye-tracking test on a mobile device (smartphone),
  • required screen resolution is 1024x968 pixels or more. Only horizontal screen orientations are supported.

To connect external tool (eg. survey) and test results with a tester you will need to modify your test recruitment link to pass in the variables you want to track. The panel provider must add the variables (different for every panelist) to the RealEye URL dynamically.

You can add custom variables to your recruitment link using a ? (question mark) and join multiple variables using an & (ampersand).

For example, if the study link is
then you need to add parameters like this:

In this example 2 variables wad added: user and company ID. This allows you to track who completed your test and match it with your survey while exporting data.

HINT: If you pass a variable called "Id" (starting with a capital letter) - the value of this variable will be visible on heatmaps dashboards next to tester demographic data.

Yes, you can download the data collected during the study as a CSV file. For more details please refer to

Also, you can download each AOI CVS file.

If there’s any data that you would like the CSV file to include, please contact us and we’ll provide any additional data.

Yes, Since version 6.10 RealEye can also collect and store basic information about Facial Coding. You can check the entertainment level in time for each of the participants and in the aggregated way. This is very useful for testing video advertisements.
Our tool doesn’t generate reports. As a result you’ll receive gaze and mouse recordings, heatmaps with an AOI tool and CSV files (including the AOI data). You can download all the data you need: heatmaps as a PNG file, recordings as an MP4 file and the CSV file, easily translated into an excel file.
There are only monthly payments, so there’s no possibility to pay per study. But keep in mind, that you can cancel your subscription any time (even in the same month) - you’ll keep the account access until the end of the billing period.
You can easily integrate the RealEye tool with external tools (eg. surveys), but also compare the results obtained from other tools using our CSV file (i.e. by the timestamp).
Yes, you can test live websites with no need to include any scripts or code on the tested websites.
