Abstract: A method of limiting noise damage to an individual includes receiving, by an ototoxicity application stored in a non-transitory memory and executed on a processor, a first individual exposure level to a first ototoxic condition in an area, correlating the first individual exposure level to an ototoxic effect, determining a noise level threshold based on the correlating, receiving a noise level exposure in the area, comparing the noise level threshold with the noise level exposure, and sending an alert when the noise level exposure exceeds the noise level threshold. The noise level threshold is below a standard noise level threshold.

Abstract: A computer system displays a representation of a field of view of one or more cameras that is updated with changes in the field of view. In response to a request to add an annotation, the representation of the field of view of the camera(s) is replaced with a still image of the field of view of the camera(s). An annotation is received on a portion of the still image that corresponds to a portion of a physical environment captured in the still image. The still image is replaced with the representation of the field of view of the camera(s). An indication of a current spatial relationship of the camera(s) relative to the portion of the physical environment is displayed or not displayed based on a determination of whether the portion of the physical environment captured in the still image is currently within the field of view of the camera(s).
