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.
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.
Real vergence data (vergence angle and gaze convergence point) in three dimensions are solved from both eyes as exact geometry.
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.
Record both eye videos at 180 fps. Replay frame by frame, or recalibrate after the fact. Not a black box.
With the ET3Space add-on, ETVision turns eye tracking into true spatial computing signals.
Output real-time ("Live") Bar Plots of object-grounded human attention distribution.
Tight enough to tell one instrument from the next, in cockpits, control rooms, and operating rooms.
Processing runs on your local system. No public cloud in the path.
The optics fit right over the wearer's prescription eyewear. No special lenses, no hidden cost.
Track the outline of an object in real time and report Gaze Position with respect to a monitor, a phone, or any defined object.
TTL sync pulses precisely line up ETVision data with data from EEG and other instruments.
Run calibration, view live video, and control recording from an iOS or Android phone. No cable needed.
Eye tracking for athletes skiing, cycling, or other activities in the wild.
The capabilities that matter when a result has to survive review.

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.
