Attention, in three dimensions.

Not a dot on a video. ET3Space is a spatial computing platform for human attention: which real object a person is attending to, where it sits in the room, and how that attention evolves.

ETVision with head-tracking reflector array, the ET3Space wearable

Attention as a spatial signal

ET3Space turns eye tracking into a true spatial computing signal. It combines gaze from ETVision with 6DoF head position from an integrated motion-capture device, then computes the line of sight and where it meets real surfaces in the room.

The result moves past 2D gaze analysis into real spatial perception analytics: measure, analyze, and model human attention directly inside a physical environment.

ET3Space

Core Spatial Computing Architecture

A real-time, human-in-the-loop spatial computing system in six layers.

Core architecture

EYE

Eye tracking layer

Captures gaze direction relative to the head.

HEAD

Head tracking layer

Motion capture provides head position and orientation in a global coordinate system.

MAP

Spatial mapping engine

Computes the line-of-sight vector and its intersection with real-world surfaces.

TWIN

Environment model

A digital twin of real-world Environment (surfaces, displays, controls) in a structured 3D space.

ATTN

Human attention model

Tracks attention on surfaces of interest and shows change live with bar plots.

VIEW

Global monitor

Shows point of gaze on surfaces from a stationary scene camera in the room.

Live human attention

ET3Space decodes attention patterns on surfaces of interest in a real environment and displays them with real-time bar plots.

  • Total time, number of fixations, average fixation duration
  • Total fixation time, time to first fixation
  • Average left and right pupil diameter
Real-time attention bar plots by surface

Real-time spatial analytics

A continuous, time-synchronized stream of spatial data:

  • 3D gaze vector, and eye position with vergence
  • Head position and orientation (6DoF)
  • Surface identification and intersection coordinates
  • Attention bar plots, pupil diameter, and physiological signals

A digital twin of environment and attention

ET3Space builds a lightweight digital twin of both the environment (surfaces, displays, controls) and the user's attention (gaze mapped into space).

Easy to set up

Surfaces are defined with a couple of clicks on the scene image, for rapid deployment in complex environments.

Aligns with spatial computing ecosystems

Bridges physical and virtual worlds, supports attention-aware interfaces and human-centered digital twins.

Provides ground truth for AI

Provides ground truth for AI perception models, and integrates with simulation environments (flight, driving, control rooms) and physical AI systems.

Multi-surface, multi-object awareness

Track many spatial targets at once:

  • Instrument panels
  • Monitors and displays
  • Physical controls and keyboards
  • Walls, floors, and environmental structures

Head-tracking systems we support

Choose the motion-capture technology that fits your environment. Our engineers help you match it. An array of reflectors on the ETVision frames lets optical systems measure head position and orientation.
