Tobii Pro X3-120

Hardware Specifications

Tobii Pro X3-120 eye tracker provides exceptional flexibility and accommodates a wide array of human behavior studies. The ultra-slim, light design makes for a compact solution. The system shows exactly where people are looking and, with a sampling rate of 120 Hz, it is designed for detailed research into the timing and duration of fixations. The Pro X3-120 is perfect for both qualitative and quantitative research, e.g. calculation of different eye tracking metrics.

Unfortunately, this hardware is no longer manufactured. Please see Tobii Pro Fusion as an equivalent alternative.

The iMotions Eye Tracking – Screen-Based Module

Main features

With the iMotions Screen-based Eye Tracking Module, you can collect and analyze data in controlled lab environments using world leading, research grade trackers from hardware providers such as Tobii, EyeTech, Smart Eye, SMI, and Gazepoint. The Module allows for advanced analysis using tools such as heatmaps, gaze replays, and areas of interest (AOI) output metrics like time to first fixation & time spent. iMotions also provides automated gaze-mapping technology, in which gaze from dynamic environments is converted to static scenes for simpler aggregation and analysis.
