A multisensory augmented reality chemistry system is introduced that delivers auditory feedback alongside visual augmentations of laboratory experiments. The system uses a video see-through AR display to overlay virtual chemical substances and reactions onto a real physical environment, including a tangible lab vessel analog. The physical vessel analog is outfitted with a sound output device (such as a small speaker or transducer) that is controlled by the AR system's processor. A unique marker on the vessel allows the system to identify the vessel and load specific audio-visual profiles from memory. As the user performs virtual experiments—pouring a liquid, mixing solutions, or witnessing a reaction—the system generates corresponding audio cues (e.g. the sound of liquid pouring, gentle boiling, or a reactive fizz) from the vessel's sound output device in sync with the on-screen virtual visuals.

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.
