Abstract
A system (2000) comprising a head-mounted device (2010); at least one position sensor coupled to the head-mounted device; at least one light-filtering shield (2012) coupled to the at least one position sensor; at least one light detector (2019); and at least one computing device (2017) configured to receive, from the light detector, an indication that an intensity of light detected by the light detector exceeds an exposure threshold; determine, from the at least one position sensor, that the light-filtering shield is not positioned at the face of a worker to filter light with the intensity that exceeds the exposure threshold; and generate, in response to the determination that the light-filtering shield is not positioned at the face of a worker wearing the head-mounted device to filter light with the intensity that exceeds the exposure threshold, an indication for output.
