The ROI circle (Region of Interest): when the breathing switch is turned on, a blue circle appears on the screen and the user can move the circle with their finger to the baby's chest and abdomen.
At this point, the breathing detection changes from global monitoring to local monitoring and more accurate measurement of breathing values can be obtained.
When the ROI circle function is turned on, the face tracking function is disabled and the pan and tilt function is disabled.
When the user manually closes the ROI or the ROI function is automatically closed, the other functions are restored by default.
You can freely drag, zoom in and out the ROI circle, covering the baby's chest and abdomen, which can greatly improve the accuracy of breathing monitoring and obtain more accurate breathing values.
