Eye-tracking company Gazepoint Research Inc. has launched the GP3 HD eye tracker, which the company considers to be the most affordable high-performance gaze tracker on the market. The GP3 HD device incorporates a high-resolution image sensor, allowing for a larger field of view as well as a higher update rate. The GP3 HD gaze tracker will provide novice and expert eye-tracking professionals alike a more natural, precise and reliable eye-tracking experience for a wide range of applications, such as usability (UI) and user experience (UX) analysis, market research, and academic investigations.
As with its predecessor, the GP3, the GP3 HD eye tracker features an intuitive and easy-to-learn user interface, with set-up requiring less than five minutes, from unboxing to data collection. The GP3 HD device also benefits from a rapid calibration process and easily interfaces with all existing hardware. The GP3 HD eye tracker builds on these strengths and also features the following upgrades:
Larger range of allowable head movement. The high-resolution image sensor provides a larger field of view than a traditional sensor, which allows users to sit and move more casually and naturally in front of the system. Even when users shift around in their seat, the system continues to capture and track their eyes. This key advantage translates into more accurate data and a more comfortable, natural eye-tracking experience for users.
Increased tracking performance. The GP3 HD device features a high sampling rate of 150 Hz— up to 2.5 times faster than the 60 Hz systems on the market. The high frame rate allows for fast head movements without loss of tracking, as no hardware region of interest is used to transmit the image from camera to computer. Every image frame is transmitted in full, capturing every minute movement of the scene every 6.6 ms. Another distinct advantage of a faster sampling rate is the rapid re-acquisition of tracking after blinks. The GP3 HD device’s 150Hz sampling rate also allows for more detailed investigations of eye and point-of-gaze movements.
Taken together, these benefits result in greater reliability and robust performance for all eye-tracking applications.
The GP3 HD is available now.
