I need to know based on what sort of accuracy does the "EYES_UP" expression work in the RealSense SDK. Say if I have two regions and I want to set the EYES_UP in a way that if I look at the upper region it returns me 100 and if I am looking at the lower region it gives me 0, how should I define my regions?
Also would that support more than two regions?
Any information is really appreciated.
Best regards,
Mona Jalal.

Hey Mona, great question. Eyes up / down / right / left expressions will only return the position of the eyes which is usually not good enough.
The feature you are looking for is gaze detection -> understanding where the user is looking at.
In the next version we will release a new sub-module inside of Face Module called Gaze Module. This module will require some calibration flow from the end-user but will try to solve your exact problem of finding out specific region the user is looking at

Hi Gal,
Thank you for the answer. Can you please show in a simple example how I can define the bounding box that is used for the expressions_eyes_up and how that algorithm exactly work? Is it true if I look above the light in the camera it is considered as up and if I look down the camera light is considered as eyes not up? Also I want to know how do you define the bounding box (like how up, right, left , down we can look)?
Thanks,
Mona Jalal.
