TOBII PRO 1.200 Hz EYETRACKING EQUIPMENT

Description:

This equipment is located in the eye recording room at the Experimental Linguistics Unit of the Institute of Applied Linguistics of the University of Cadiz, second floor of the Multipurpose Building, at the Cadiz campus. It consists of Tobii Spectrum 1,200 Hz hardware and Tobii Pro Lab Full Edition software.

Characteristics of the Tobii Pro Spectrum eye tracker system:

1. Collects precise and accurate gaze data.
2. Integrated processing unit.
2.2. The system meets the most stringent demands of studies requiring a high sampling rate; e.g. the need to study eye movements such as microsaccades, saccades, correction saccades, fixations, changes in pupil size and blinks. The high stability of the sampling rate (<0.3% variability) allows precise synchronization of gaze data with data from other sources, e.g. EEG systems (hardware synchronization: the system can send or receive stimuli). The sampling rate is used to detect subtle eye movements, such as microsaccades.

Unique features of the Tobii Pro Lab analysis software package:

The Pro Lab software, suitable for conducting experiments with the Tobii Pro Spectrum eye tracker, has 3 modules for Design, Recording and Analysis of the data obtained and includes, among others, the following unique features:

– Feedback from the researcher to the participant in real time (gaze position available on the secondary monitor) through live viewing functionality.
– Automatic calibration validation for more accurate estimates of data quality after eye tracker calibration
– Dynamic areas of interest (AOIs) tool
– Segment-based analysis for the video stimulus
– Instant access to collected data through visualization tools (e.g., heat maps, gaze streams, etc.) and comprehensive statistics (time to first fixation, fixation duration, etc.)
– Set of saccadic metrics available for exporting saccadic eye movement measurements, such as amplitude, peak velocity, and direction
– Speed and ease of experiment design, analysis and communication of large volumes of data
– Tobii I-VT fixation filter with customizable thresholds and filtering methods
– Noise reduction filter using moving median
– GSR compatibility (Shimmer already integrated)
