Abstract
In some examples, a system includes a head-mounted device, a visor that includes a reflective object that is substantially transparent in a visible light spectrum and embodied at a physical surface of the visor, at least one visor attachment assembly that couples the visor to the head-mounted device; at least one optical sensor; and at least one computing device communicatively coupled to the at least one optical sensor, the at least one computing device comprising a memory and one or more computer processors that: receive, from the optical sensor, an indication of light outside of a visible light spectrum that is reflected from the reflective object; determine, based at least in part on the light outside of a visible light spectrum that is reflected from the reflective object, a position of the visor; and perform, based at least in part on the position of the visor, at least one operation.
