FAQs head mounted solution

“What are the performance rates and specs of your device?”

Based on our thorough tests, the angular accuracy is approximately 1.7 degrees (mean) / 1.2 degrees (median). Precision is 0.09 degrees [Hooge et al. 2022]. Sampling frequency is 50 Hz. The resolution of the scene image is VGA (640×480).


“How do I retrieve the data from the device?”

The SeeTrue software includes a GUI-client which allows calibration of the user, displays the scene images with overlaid gaze points, and records the data streams. The user can also develop their own client application using our API documentation. In addition, the system provides the data through the LSL protocol.


“What data does the system provide”

The output data contains the standard gaze tracking parameters: timestamp, frame count, gaze point in the scene camera coordinates, pupil size, pupil area (in pixels and mm2), score values, eye events, and optionally the gaze point mapped into various markers (up to four); the scene video is also outputted.


“Does the SeeTrue software provide any analysis tools?”

The software comes with a post-processing tool which renders a video of all the recorded scene images, superimposed with the gaze points. The synchronized data contains the eye events (saccades, blinks, and fixations with their durations and coordinates) that can be used for analysis. SeeTrue output data is compatible with commercially available analysis tools.


“Does your system work with eyeglasses?”

Based on our experiments, our system works pretty well with eyeglasses. Very thick eyeglasses may result in an occasionally unsatisfactory performance. Contact lenses are generally fine to use.


“Does your device work outside?”

Extreme sunlight can be a problem for any gaze tracking systems, but our solution is very robust. A cap or a hat is suggested nevertheless.


“When should I expect to receive my device?”
The delivery time is two months or faster.


“Do you have online documentation?”
Yes, we have exhaustive documents for User guide and the Client API. The latter comes with example codes. In addition, we have lots of videos to serve as teaching material.
