Sensor assisted head mounted displays for welding are disclosed. Disclosed example head mounted devices include an optical sensor, an augmented reality controller, a graphics processing unit, and a semi-transparent display. The optical sensor collects an image of a weld environment. The augmented reality controller determines a simulated object to be presented in a field of view, a position in the field of view, and a perspective of the simulated object in the field of view. The graphics processing unit renders the simulated object based on the perspective to represent the simulated object being present in the field of view and in the weld environment. The display presents the rendered simulated object within the field of view based on the position. At least a portion of the weld environment is observable through the display and the lens when the display is presenting the rendered simulated object.

System has an optical sensor (1), an aperture with the optical element (2) with the changeable permeability and an activation light (3) emitting radiation, which is detected by the optical sensor (1). The activation light is connected with the switch (4) and it is placed within the reach of the optical sensor (1). Within a device which realizes the technological process with the luminous manifestation the instruction for the beginning of a given technological process is detected and on the basis of this instruction the activation light (3) lights up. This activates the optical sensor (1) by means of the activation light (3) before the optical sensor (1) detects the luminous manifestation of the technological process itself. The activation light (3) can be a simple infrared LED diode. The advantage lies in the fact that the protective device itself does not have to be modified in any way and its reaction time can be shortened to zero, or negative reaction time can be achieved since we use time passing during the initiation of the technological process before the appearance of the luminous manifestation for the darkening.
