Patent Images

1. A welding interface device, comprising:

  • an optical sensor to collect an image of a weld environment comprising;

    an illuminator to output a radiation at a first wavelength outside of an arc radiation spectrum;

    a time-of-flight sensor to collect the image of the weld environment at the first wavelength; and

    a bandpass filter to mitigate light at wavelengths other than the first wavelength;

    an augmented reality controller to, based on the image of the weld environment and first instructions that correspond to a weld operation in the weld environment, determine a simulated object to be presented in a field of view, a position of the simulated object in the field of view, and a perspective of the simulated object in the field of view;

    a graphics processing unit to render the simulated object as a three-dimensional stereographic image based on the perspective to represent the simulated object being present in the field of view and in the weld environment;

    a semi-transparent near-eye display to present the rendered simulated object within the field of view based on the position determined by the augmented reality controller, at least a portion of the weld environment being observable through the semi-transparent display when the display is presenting the rendered simulated object; and

    a body, the optical sensor, the graphics processing unit, and the display being attached to the body, the body dimensioned to, when worn by a wearer, enable the wearer to further wear a welding helmet over the body, the welding helmet having a viewing port;

    wherein the augmented reality controller is to;

    based on additional images collected by the optical sensor, determine an interaction by a wearer of the welding user interface device with the simulated object; and

    determine a response to the interaction with the simulated object by the wearer.
