CoolTool Eye Tracking user manual
If you are going to use eye tracking device, your PC/laptop must be equipped with:
- USB 3.0 port (blue one, SuperSpeed)
* Please note that the ASMedia XHCI controller is not supported for the Eye Tracker Pro
- Intel CPU starting from Core i3 or newer (i5/i7)
- Windows 8 / 10 operating system
- InternetExplorer 11 and stable Internet connection
CoolTool software requires .NET Framework 4.5 or later. These prerequisites can be installed for you. Simply accept them, when asked by the installer.
Before using the eye tracking device:
- Unpack carefully and connect your eye tracking device to computer via USB 3.0 port*. Verify if the system recognized the device and the drivers were installed properly**.
* Remark: Please note that the ASMedia XHCI controller is not supported for the Eye Tracker Pro.
** Remark: This notification is shown in the lower-right corner of the screen (horizontal Quick Access Panel). If you haven’t noticed the notification, find the eye tracking device in the list of devices (Control Panel –> Device Manager) and check if it works properly.
- The eye tracking device should be placed in front of the screen (note, that for correct work of the device your CRT size must not exceed 24 inches), so that respondent’s eyes are approximately at 45-75 cm distance from the screen. Here is the illustration of how the eye tracking device can be placed:
Besides, you can order an exclusive mounting kit for laptops and tablets
- Launch the CoolTool Eye Tracking application.
In order to see how the eye tracking device works you can run a test survey by entering the following code into survey upload field: y3cp72v
When the calibration starts, the respondent should sit straight against the device, so that the white points (which track the position of respondent’s eyes) were within the green circle. Then he/she has to follow the blinking dots (without moving their head) until the notification about successful calibration appears on the screen. After calibration is completed visuals can be shown to the respondent.
Important! When viewing images/photos, the respondent must sit exactly in the same position as during the calibration and must not move his/her head, lean back/forward/sidewise, move the chair, etc.. When respondent has switched to text questions he/she can feel free to move.

Five-star calibration ratings meaning:
|Perfect||This is an optimal calibration result. No recalibration is needed. (error < 0.5°).|
|Good||This calibration result is well-suited for eye tracking (error < 0.7°).|
|Moderate||This calibration result is acceptable but you should try to improve your result with a re-calibration (error < 1°).|
|Poor||This is not an optimal calibration result. You should try to improve your result by re-calibrating (error < 1.5°).|
|Re Calibrate||Your current calibration result is no good for eye tracking. Re-calibrate after verifying that you have good tracking.|
