Performance Specifications

1. Technical parameters of eye tracking core module:

Sampling rate: ≥ 1500Hz when both eyes are collecting simultaneously;

Resolution: ≤ 0.02°；

Accuracy: ≤ 0.5°；

Real time tracking delay: ≤ 2ms；

2. One machine with multiple functions, capable of upgrading to a tower eye tracking system. The eye tracker is located above the subject's head and uses a transparent infrared reflector to track the eyes. It can be used for close range screen stimulation or touch screen. Please provide relevant information about the device;

3. Using Ethernet for data transmission;

4. The infrared light source and high-speed eye tracking camera can be separated, and different wavelengths of infrared light sources can be configured to adapt to different experimental environments;

5. Provide SDK program interfaces that can be used in conjunction with E-Prime and Matlab;

6. Support expanding synchronized records for multiple people.

Instrument Applications

Human information processing largely relies on vision, and the study of eye movement is the most effective means of visual information processing research. Therefore, eye tracking systems have become effective tools for experimental research in education, psychology, linguistics, artificial intelligence, and other fields. The main function of an eye tracking system is to analyze the position and duration of the gaze area, pupil movement, and pupil diameter of the test subject, in order to reflect their attention and cognitive processes towards objects. The system also includes experimental design software, which allows experimenters to design various visual and auditory stimuli at multiple levels through user-friendly visual user pages.
