Gaze Mode
You can configure Neon to generate binocular or monocular gaze data by changing the Gaze Mode in the Neon Companion app settings.
In Binocular mode, gaze data is generated using images from both the left and right eyes. This is the default setting and is recommended for most users.
Some specialist applications, like ophthalmic testing, require gaze data to be generated from just one eye. This can be achieved by switching to a Monocular gaze mode. Monocular Left generates gaze data using only images of the left eye, while Monocular Right uses only images of the right eye.
Changing Gaze Modes
You can switch between gaze modes in the Neon Companion app settings.
INFO
After selecting a new gaze mode, be sure to unplug and re-plug the Neon device.
Considerations When Switching to Monocular Gaze
If a monocular gaze mode is selected, no binocular gaze signal will be generated. This means all downstream data, including fixations and enrichment data, will be based on monocular gaze data.
Eye State and Pupillometry are unaffected by the gaze mode configuration and will always be generated using images from both eyes.
If a monocular gaze mode is selected, Pupil Cloud will not re-process a recording to obtain a 200 Hz signal. Instead, Pupil Cloud will use the real-time signal, which may be lower than 200 Hz depending on which Companion device was used, and which gaze rate was selected in the Neon Companion app settings.
