GazePoint GP3 HD Eye Tracker 150 Hz

GazePoint GP3 ​​HD Eye Tracker 150 Hz

GazePoint GP3 ​​HD is a stationary, research-grade eye tracker designed to record the user's gaze while interacting with a screen. The device utilizes a machine vision camera [an industrial camera designed for computer vision] and offers a sampling rate of up to 150 Hz, allowing for a maximum of 150 gaze position measurements per second.

This model is primarily aimed at research institutions, universities, UX [User Experience] laboratories, and developers creating their own applications using gaze direction data.

The device can be used for, among other things, the following:

Website and application usability testing,
User behavior analysis,
Psychological and cognitive research,
Academic research,
Neuromarketing,
Creating gaze-controlled applications,
Integrating eye tracking with custom research software.
