Tobii Glasses X is engineered to provide a balance between ease of use, portability, and reliable eye tracking performance for commercial, industrial, and applied research environments. Tobii Glasses X uses a calibration-free approach, enabling users to start recording virtually instantly, in contrast to conventional research-focused wearable eye trackers that need participant calibration prior to each recording. This drastically cuts down on setup time and making the system ideal for businesses who perform several research, training sessions, workflow evaluations, or field observations all day long.

Eye Tracking Technology:

Tobii Glasses X uses binocular pupil-center corneal reflection (PCCR) eye tracking with the dark pupil method.

Eye Tracking Specifications:

• Eye tracking method: Binocular pupil-center corneal reflection (PCCR)

• Tracking method: Dark pupil

• Sampling rate: 120 Hz

• Eye tracking accuracy: Approximately 1.5°–2.5°

• Built-in 3D eye tracking model

The built-in 3D eye tracking model automatically compensates for minor movement of the glasses during use, helping maintain reliable gaze estimation without requiring recalibration.

Calibration-Free Workflow:

Tobii Glasses X uses a calibration-free process, in contrast to conventional wearable eye trackers with a research focus.

This allows users to:

• Begin recording almost immediately

• Reduce setup time

The calibration-free workflow makes the system well suited for organizations conducting:

• Multiple studies

• Training sessions

• Workflow assessments

• Field observations

throughout the day.

Scene Camera:

Tobii Glasses X features a 2.5K scene camera that captures the participant's perspective.

Camera Specifications:

• Resolution: 2560 × 1440 (2.5K)

• Frame rate: 30 frames per second

• Field of view:

  • 132° diagonal

  • 118° horizontal

  • 67° vertical

Researchers can see nearly everything in the participant's natural viewing region thanks to the broad field of view.

Audio Recording

Integrated stereo microphones record synchronized audio, enabling:

• Conversations

• Verbal protocols

• Environmental sounds

to be reviewed alongside gaze data.

Wearable Design:

The wearable unit weighs:

• 72 grams (including cable)

This makes it comfortable for prolonged use in:

• Industrial environments

• Retail stores

• Production facilities

• Healthcare settings

• Field studies

Motion Tracking Sensors:

The glasses incorporate:

• Accelerometer

• Gyroscope

• Magnetometer

Researchers can better understand how head movements relate to visual attention during dynamic tasks by using the synchronized motion data that these sensors provide.

Power & Connectivity

Power is supplied directly through:

• USB-C connection

This eliminates the need for an external battery pack and simplifies deployment in enterprise environments.

Summary

When combined, these features offer Tobii Glasses X an easy-to-implement eye tracking solution for businesses looking for quick behavioral insights without the complexities of conventional wearable eye trackers for research.
