Introducing the Gazepoint GP3 HD
We are very happy to announce the release of our newest eye tracking system, the GP3 HD. The GP3 HD system maintains all the great features of the GP3, it’s very easy to setup, quick to calibrate, interfaces with all existing hardware accessories (Laptop & VESA screen mounts) and software (Gazepoint Analysis & Remote Viewer). And it’s still the most affordable high performance research system on the market.
As the names suggests the GP3 HD has an upgraded imaging system which uses a larger HD image sensor and a USB3 interface to allow for a larger field of view. The GP3 HD will also be offered in either 60Hz or 150Hz variants. The GP3 HD is a significant upgrade with the following benefits:
Increased allowable head movement: The larger sensor allows for a larger field of view which lets users sit and move more casually and naturally in front of the system. Even when a participant slouches or shifts around in their seat, the system will be able to continue to see and track their eyes. This means less data loss due to movement of the participants and a more comfortable experience for the users.
Increased tracking performance (150Hz): The higher sampling rate of 150Hz reduces the chance of a loss of tracking due to fast head movements. The amount of movement that can occur between image frames is reduced from 16.6ms on a 60Hz system to 6.6ms on the 150Hz GP3 HD system. While loss of tracking is much reduced, blinks still result in a loss of tracking, however at the 150Hz update rate, the GP3 HD can re-acquire tracking up to 2.5 times faster than the GP3. The increased update rate further reduces potential data loss due to blink re-acquisition times and participant movement.
Increased sampling rate (150Hz): In addition to the more robust tracking performance, the higher update rate results in a higher sampling rate which allows more detailed investigation into eye and point-of-gaze movements.
