-The Neon module features two eye cameras, one for each eye. They are located at the tip of the small arms of the module. The sensors record IR video at 200 Hz with a resolution of 192x192px. The two sensors are synced in hardware, such that they record images at the exact same time. The resulting images a concatenated in a single video stream of 384x192px resolution.

 An IR LED is located just above each camera, which guarantees good illumination of the eye in dark environments.

-The achieved framerate can vary based on what Companion device is used and environmental conditions. On the OnePlus 10 and Motorola Edge 40 Pro, the full 200 Hz can generally be achieved outside of especially hot environments. On the OnePlus 8, the framerate typically drops to ~120 Hz within a few minutes of starting a recording. Other apps running simultaneously on the phone may decrease the framerate.

-The Neon Companion app can provide  3D eye states data in real-time at up to 200 Hz. The 3D eye states are a time series of each eye's position and orientation in 3D space, given by the location of the eyeball center and the optical axis of each eye. The units are milimeters.

 ## Pupil Diameters
 
 <Badge>Real-time</Badge><Badge>Pupil Cloud</Badge>
-The Neon Companion app can provide pupil diameter data in real-time at up to 200 Hz. Separately for the left and right eye. The computed pupil diameters correspond to the physical pupil size in mm, rather than the apparent pupil size in pixels as observed in the eye videos. You can find a high-level description as well as a thorough evaluation of the accuracy and robustness of Neon’s pupil-size measurements in our [white paper](https://zenodo.org/records/10057185).

 Similar to the 3D eye states, the accuracy of the pupil diameter measurements improves when supplying the wearer's IED in the wearer profile before making a recording.
