Advanced API Signals
Tobii Ocumen provides you with advanced eye tracking signals and data for scientific-grade analysis and applications. In-depth analysis enables new use cases, particularly in health-related applications and advanced research in academia or industry.
The following advanced eye tracking signals and data are included:
Left and Right Gaze Rays
In addition to the combined direction signal, you get access to each eye’s separate direction and origin. An example use case of this is detecting and treating strabismus or lazy eye.
The user’s pupil size, which changes according to light intensity, emotion, and other factors. This could for example be used in conjunction with other biometrics to measure a person’s emotional response to a stimulus. Most eye trackers cannot compensate for the magnification caused by a pair of eye glasses, so consider monitoring the relative changes of pupil diameter rather than absolute values.
This signal tells you if the headset is in a good position relative to the user’s eyes, which is useful to guide users to adjust their headset into the optimal position for rendering and eye comfort. This can also be used to detect if users adjust the headset during a recording or session.
System and Device Timestamps
The device timestamp is used to synchronize the eye tracker clock with the host system clock in order to correlate eye tracking data with events happening on the host system. On the Pico Neo 2 Eye, system timestamps have been synchronized to the host system clock and can be used directly.
Metadata about the connected eye tracker, containing information about the model, serial number, runtime version and output frequency. Useful for debugging purposes or when describing the eye tracking hardware in a study design.
See Advanced API for full details.
Tobii Ocumen provides you with access to pre-made eye movement filters for classifying eye behaviors such as fixations and saccades among others, as well as the ability to customize them. The eye movement classifiers and processors (which are listed in the Filter Documentation) are applied via a flexible filter pipeline.
The Configuration package allows you to add a calibration and position guide into your application, customize them to suit your needs as well as evaluate the calibration quality.
The calibration can be embedded in your application, meaning users will not need to open a different app to calibrate. The calibration can also be customized with different animations, calibration point sequences and lengths, colors and more.
See the Configuration Overview page for more info.
Evaluate the quality of the user calibration to get an estimate of expected gaze performance for different stimuli and angles directly accessible from an API. The accompanying calibration quality sample visualizes the gaze performance.
See the Calibration Quality page for more info.
Tobii Ocumen Studio & the Recorder Components
The recorder components allow you to create your own
.ocumen files which you can either playback or stream live directly to Tobii Ocumen Studio.
