Abstract: A system and method for inferring operator intent by detecting operator focus incorporates cameras positioned within a cockpit or control space of a vehicle and oriented at an operator of the vehicle. The cameras capture images of the operator in a control seat; the images are analyzed (either individually or sequentially) to determine a gaze and/or body pose of the operator (including, e.g., a position and orientation of the torso and limbs). By comparing the determined gaze and/or body pose to the positions and orientations of potential focus targets within the control space (e.g., windows, display units, and/or control panels that the operator may engage with visually and/or physically), the system predicts the most likely future focus target or targets: what the operator is most likely to visually and/or physically engage with next. Operator intent may be further analyzed to identify potentially abnormal or anomalous behavior.

Abstract: Systems and techniques are described for extended reality (XR) operations. An XR system displays virtual content using a display according to display settings. The display settings can identify, for instance, a position, orientation, and/or size of the virtual content as displayed. The environment can be viewable using the display as the virtual content is displayed by the display, for example using a see-through display or a pass-through display. The imaging system can determine, based on one or more attributes of one or both eyes of the user of the imaging system, an extent of perception of the virtual content that is displayed using the display by the user. The attributes can identify, for instance, eye position, eye movement, pupil dilation, saccades, fixations, blinking, and/or squinting. The XR system can determine, based on the extent of perception of the virtual content by the user, a modification to the display settings.
