Abstract: Various implementations disclosed herein use user input received approximately around the time of food consumption to confirm and/or revise food predictions, e.g., regarding type of food, volume, etc. One or more food characteristics determinations may be associated with uncertainty. User input is implicitly or explicitly requested to resolve at least some of such ambiguities and uncertainties approximately around the time of food consumption. The user feedback experience may be configured to be easy and unobtrusive by presenting limited options in limited circumstances and using easy and intuitive input mechanisms. As examples, such feedback may involve a user using gaze input, a voice command, or a hand gesture to quickly identify whether an uncertain item is of one type or another type, e.g., mashed potatoes or ice-cream. In some implementations, the obtrusiveness/burden of requiring live input for every food determination is avoided or reduced by only asking about some items.

Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. To determine whether the light emitter has caused these artifacts, a display light sensor under the display may measure backside light leakage from the display. Based on the measured backside light leakage, the display light sensor or control circuitry may determine whether artifacts in the display exceed a predetermined acceptable artifact range. If the artifacts exceed this range, the artifacts may be mitigated. To mitigate the artifacts, the light emitter and/or the display may be adjusted. For example, the timing and/or dosage of the light emitter, the acceptable artifact range, and/or the timing of display content may be adjusted. In this way, the display light sensor may be used to form a closed-loop system to determine whether artifacts are present in the display and to mitigate those artifacts.
