Products / ETVision

The leader in 3D eye tracking,
on your head.

Our core product. Both eyes at 180 Hz, wearable anywhere, with three add-ons that extend it: ET3Space, AI object detection, and the Stationary Scene Camera.

ETVision wearable eye tracker

What sets it apart

Two capabilities define ETVision: true 3D gaze and Live AI MOT (Multiple Object Tracking). Together they specify attention precisely, with respect to real objects, in real time, and in real space.

3D ★

True 3D gaze

Real vergence data (vergence angle and gaze convergence point) in three dimensions are solved from both eyes as exact geometry.

AI ★

Live AI MOT

A standard 80-object AI model ships with every system. Train custom AI models on your own objects. And ETVision names what the wearer looks at, live on the platform.

VERIFY

180 fps eye video

Record both eye videos at 180 fps. Replay frame by frame, or recalibrate after the fact. Not a black box.

SPATIAL

Digital Twin of Real World

With the ET3Space add-on, ETVision turns eye tracking into true spatial computing signals.

SMART

Semantic recognition

Output real-time ("Live") Bar Plots of object-grounded human attention distribution.

0.5°

Accuracy that holds up

Tight enough to tell one instrument from the next, in cockpits, control rooms, and operating rooms.

SAFETY

Data stays with you

Processing runs on your local system. No public cloud in the path.

FRIENDLY

Use your own glasses

The optics fit right over the wearer's prescription eyewear. No special lenses, no hidden cost.

LAOI

Live areas of interest

Track the outline of an object in real time and report Gaze Position with respect to a monitor, a phone, or any defined object.

SYNC

EEG and beyond

TTL sync pulses precisely line up ETVision data with data from EEG and other instruments.

PHONE

ETPhone

Run calibration, view live video, and control recording from an iOS or Android phone. No cable needed.

WILD

SD card recording

Eye tracking for athletes skiing, cycling, or other activities in the wild.

Features

  • Precise binocular measurement at 180 Hz, with automatic vergence correction for accuracy at any distance.
  • Pupil diameter and eyelid position measurement, with real-time blink detection.
  • Worn over the participant's own prescription glasses. No special lenses.
  • High-definition scene image with support for real-time object tracking.
  • Fast setup: auto feature detection with single-point calibration.
  • Left eye, right eye, and scene images in the GUI, with live point-of-gaze and recognition feedback.
  • Two-way audio between investigator and participant during the task.
  • Synchronous recording from an external Stationary Scene Camera.
  • Integrates with motion capture for ET3Space 3D gaze in real-world frame.
  • Real-time network communication with external devices.

Eye tracking data, live and recorded

At 180 Hz: point of gaze on the scene image, gaze direction, fixations, blinks, eye locations, gaze vergence, pupil diameter from an ellipse fit, eyelid position, and gaze engagement with AI-detected objects or live areas of interest. All of it streams over the network and records to file. Recording can be triggered from an external device.

Used in defense and aerospace, flight and rail simulation, surgical robotics, medicine and radiology, neuroscience and pharmaceutical research, control rooms, automotive and driver monitoring, sports performance, and robotics research. See applications.
