SOMA Aware · SOMAREALITY — Cognitive load and attention from eye tracking data

SOMAREALITY software for analysing eye tracking recordings. It estimates indicators of cognitive load, conscious perception, attention type and fatigue. Brightness compensation helps reduce the effect of lighting changes on cognitive-load estimates. Results depend on data quality, calibration and recording conditions.

How it works

The pupil responds to mental effort and light

Pupil diameter responds to both cognitive processes and lighting. SOMA Aware uses a pupillary light reflex model to reduce the influence of brightness and estimate cognitive load. Estimates depend on the recording, calibration and study conditions. The illustration below explains this principle.

  1. The eye tracker provides pupil dataAnalysis requires access to raw pupil diameter. Device and data-format compatibility should be confirmed before the study.
  2. Scene video helps estimate brightnessA pupillary light reflex (PLR) model uses image brightness to estimate its influence on pupil diameter.
  3. The model estimates cognitive loadThe adjusted signal supports an estimate of load and its confidence. Calibration helps adapt the model to the person and recording setup; results need to be interpreted in the context of the task.
Lighting and cognitive processes

Pupil changes have multiple causes. Model-based brightness compensation reduces one influence; it does not mean that all confounding effects are removed.

SOMAREALITY technology and requirements

Digital biomarkers

From gaze data to estimates of cognitive load and attention

SOMAREALITY describes its indicators as digital biomarkers. The models use pupil and gaze-behaviour data to estimate selected aspects of cognitive processing. Available modules depend on the selected licence.

CL · Cognitive Load

How much effort a task takes

Cognitive load describes the demands a task places on cognitive resources. SOMA Aware complements gaze direction with an estimated load indicator that can be compared with the task timeline.

  • task and interface complexity — which steps are hardest
  • comparing load during training or between groups, with the study protocol taken into account
  • analysing changes in the indicator after an event
  • analysing increased load in demanding or stressful tasks

CPI · Conscious Perception Index

Estimating conscious perception

Not everything the eyes land on reaches awareness. CPI combines fixation and saccade metrics, gaze distribution and cognitive load with knowledge from cognitive psychology, and estimates the probability that what the participant is looking at was processed consciously.

  • analysing the probability that an operator consciously processed a warning
  • UX and packaging: comparing elements by estimated conscious perception
  • education: analysing perception indicators during learning

ATC · Attention Type Classification

How the participant's attention works

The algorithm classifies every frame of the recording and reports the probability of three attention types:

  • sustained — long focus on one task, e.g. reading or monitoring a radar screen
  • selective — choosing one stimulus despite distractions, like a conversation in a noisy café
  • switched — moving quickly between tasks, e.g. email and a phone call

Applications: workstation ergonomics, training, systems that adapt to the user's state — also in VR.

CF · Cognitive Fatigue

When the mind starts to tire

Cognitive Fatigue is a cognitive-fatigue indicator described by the manufacturer. It can support analysis of changes during a prolonged task. Live analysis requires a compatible data stream and an appropriate eye tracker integration.

  • studying changes in the indicator during long tasks and breaks
  • analysing fatigue in studies of drivers, pilots and operators
  • comparing indicators with training outcomes across session phases

SOMA Aware analyses scene-camera video together with a compatible eye tracking data file. Before purchase, the export format, required fields and software versions should be confirmed for the selected setup. Biomarker results can be viewed on a timeline with statistics and charts. The manufacturer describes current processing as local (on-premise).

Why SOMA Aware from Interlab

More than pupil diameter from an export

Raw pupil diameter and a model-based load indicator are different quantities. This comparison explains the role of compensation and interpretation; it does not compare every eye tracker feature or analysis method.

What biomarker results mean

SOMAREALITY publishes technology descriptions and research materials. Model output is an indicator to analyse under defined conditions; it is not a direct reading of thoughts or a standalone determination of a person's state.

Frequently asked questions

Does SOMA Aware replace an eye tracker?

No. It is analysis software — the data is collected by an eye tracker, e.g. Tobii Pro Glasses 3 or Tobii Glasses X. SOMA Aware computes cognitive biomarkers from it. If you don't have glasses yet, we will prepare a quote for the complete setup.

Does analysis work under changing lighting?

The SOMAREALITY model accounts for scene brightness to reduce its influence on load estimates. It does not remove all confounding effects. Data quality, camera exposure, calibration and recording conditions affect interpretation.

Can I analyse recordings I already have?

You need scene-camera video and a compatible eye tracking data file containing the required pupil and gaze data. Confirm the export format, required fields and software versions before purchase; a TSV file alone does not replace scene video.

Can analysis run live?

The manufacturer describes both live and recorded-data analysis. Live mode requires a compatible data stream and the appropriate eye tracker integration; confirm these for the specific setup.

Does participant data go to the cloud?

The manufacturer describes the current version as local (on-premise), with a cloud option announced. Confirm processing arrangements and system requirements for the selected version and configuration.

Does SOMA work with VR headsets?

The manufacturer offers its algorithms for selected VR headsets with eye tracking, but this requires project-based integration. Describe your hardware and study — we will pass on the request and get back to you.

Can I try SOMA Aware before purchase?

Ask about presentation options and availability of a limited-term licence for your project. Contact Interlab.
