1.1.1 Overview
This document describes the features and functionality of the Tobii X2 – 60 Eye Tracker. The X2 Eye Tracker is a stand-alone eye
tracker that can be used in various setups by attaching it to monitors, laptops or for performing eye tracking on physical objects.
The eye tracker requires some assembly before first time use and after transport.
The Tobii X2 Eye Tracker is an unobtrusive eye tracker for detailed research of natural behavior. Its large freedom of head move-
ment allows the participant to move during recording while maintaining accuracy and precision. The Tobii X2 Eye Trackers offer
maximum flexibility with numerous software and stimuli setup options.
The Tobii X2 – 60 is a small eye trackers measuring only 184 mm (7.2 ’’ ) in length. It enables your portable eye tracking lab and
studies that require an eye tracker to track even large objects at close distances (up to 36° gaze angle). Use the eye trackers to
conduct studies on:
• Laptops
• PC monitors up to app. 25 ʺ (16:9)
• Mobile devices
• Real-world interfaces
• Projections, simulators
• TV screens
1.1.2 Basic Operating Principles
During tracking, Tobii Eye Trackers use infrared illuminators to generate reflection patterns on the corneas of the participant ’ s
eyes. These reflection patterns, together with other visual data about the participant, are collected by image sensors. Sophisti-
cated image processing algorithms identify relevant features, including the eyes and the corneal reflection patterns. Complex
mathematics is used to calculate the 3D position of each eyeball, and finally the gaze point; in other words, where the participant
is looking.
Tobii Eye Trackers are designed for use in indoor office environments.
