Tobii Ocumen - XR
Tobii Ocumen

Powering advanced VR applications

Tobii Ocumen is an advanced toolkit for observing user behavior in VR. It provides developers with a framework to record, organize, and analyze biometrics as well as rapidly build and deploy scientific-grade VR products in specialized industries such as healthcare and medical assessment.


We designed this toolkit for researchers and developers to provide access to new kinds of data, gain insight into cognitive processes, and develop scientific-grade applications in domains such as health assessment, therapeutics, training, and simulation. Tobii Ocumen is compatible with enterprise VR headsets integrated with our eye tracking — PICO Neo 3 Pro Eye and HP Reverb G2 Omnicept Edition.

Use in health assessment

By providing biometrics such as gaze vector and pupil diameter for each eye individually, Tobii Ocumen can expedite the research and development of innovative detection and assessment solutions in areas like neurology, vision impairment, and cognitive load assessment.

Use in therapeutics

The accurate eye movement and pupil-size measurements Tobii Ocumen delivers make it possible to identify microscopic changes in user behavior — the kind of insight essential for the research and development of new therapeutic solutions.

Use in training and simulation

An application can combine robust pupil dilation data delivered by Tobii Ocumen with additional sensor data (GSR and EEG) to generate drowsiness, distraction, and cognitive load signals — which in turn provide a deep understanding of performance and skill.


Tobii Ocumen features

Record and replay any data

Tobii Ocumen combines comprehensive access to data, including advanced eye tracking signals, controller events, 3D object movements, and user view video — all in a unified format. Ready-made recorders integrate easily with Unity projects, and Tobii Ocumen Studio provides instant visual inspection of recorded data. Samples provide ready-to-use templates for typical study paradigms.

High-quality data

We have optimized the data structure for speed and file size to uphold data integrity. To support data conversion, data collection from multiple sources and ensure data remains accessible irrespective of programming language, we have designed Tobii Ocumen with an open I/O interface. Ensuring your research remains robust and product architecture flexible.

Hassle-free setup

Out of the box, Tobii Ocumen delivers all the necessary infrastructure for data collection — database formats, file size optimizations, and data I/O layers — with convenient visualizations and filter libraries to analyze eye movement data.

Lab and field telemetry

Tobii Ocumen provides a fast and lightweight framework for automating the collection of attention data in lab and field scenarios.

Data collection your way

We have designed Tobii Ocumen to integrate with other analysis tools, programming languages, and platforms. The sans-IO database ensures that you can access your data from Unity as from Python, Rust, or MATLAB.

Rapid development

Tobii Ocumen combines high performance data formats with powerful filtering libraries and provides broad support for various programming languages. Helping you cut development time and iterate ideas rapidly with short time-to-market.

Customer testimonials

  • Tobii Ocumen makes it easier for us to run our software and do our analysis. Everything is being filtered for us. All the high frequency gaze data are captured, processed, and filtered — a step we hadn't previously been able to utilize. When the data gets to us, it's ready for our implementation. It's a tremendous time-saver, and it puts the raw data into a consumable format.
