Tobii Pro Glasses 3 combines advanced eye tracking hardware with a lightweight wearable design to deliver high-quality gaze data in dynamic research environments.

Eye Tracking Specifications:

• Eye tracking method: Binocular eye tracking

• Technology: Tobii's infrared corneal reflection technology

• Eye model: Patented 3D eye model

• Sampling rates: 50 Hz and 100 Hz

• Typical gaze accuracy: 0.6°

• Automatic parallax compensation

• 3D slippage compensation

These features improve measurement quality during natural movement while allowing researchers to select the sampling rate appropriate for their study.

Eye Tracking Technology:

Tobii's unique 3D eye model and infrared corneal reflection technologies enable Tobii Pro Glasses 3 to track both eyes concurrently with exceptional robustness over a broad range of participants and experimental settings.

Scene Camera:

The integrated scene camera records synchronized first-person video to capture the participant's visual environment.

Camera Specifications:

• Resolution: 1920 × 1080 (Full HD)

• Frame rate: 25 frames per second

• Video compression: H.264

• Field of view:

  • 106° diagonal

  • 95° horizontal

  • 63° vertical

The wide field of view allows researchers to capture a broad representation of the participant's surroundings without significantly obstructing natural vision.

Audio Recording:

An integrated microphone simultaneously records - 16-bit mono audio. This provides additional contextual information during behavioural observations and participant interviews.

Wearable Design:

The head unit is designed for comfortable use during prolonged research sessions.

Hardware Specifications:

• Weight: 76.5 grams (including connecting cable)

• Four dedicated eye tracking sensors

  • Two sensors per eye

Motion Tracking Sensors:

Integrated inertial measurement sensors include:

• Gyroscope

• Accelerometer

• Magnetometer

These sensors are particularly valuable for analysing head movements alongside eye movements during activities such as walking, driving, sports, or industrial tasks.

Connectivity & Synchronization:

The recording unit includes:

• Ethernet

• Micro USB

• Dedicated 3.5 mm TTL synchronization port

These interfaces enable precise synchronization with external research equipment such as EEG, EMG, fNIRS, physiological acquisition systems, and motion capture platforms.

Recording Unit:

The portable recording unit stores data on standard SDHC or SDXC memory cards.

Recording Specifications:

• Storage: SDHC / SDXC memory cards

• Continuous recording: Approximately 105 minutes

• Battery: Rechargeable 3400 mAh lithium-ion battery

Calibration:

Calibration is designed to be quick and efficient with support for:

• One-point calibration

• Automatic calibration

This reduces setup time while maintaining high tracking accuracy.

Summary:

Together, these specifications make Tobii Pro Glasses 3 suitable for demanding scientific research where reliable eye tracking, portability, and multimodal integration are essential.
