Abstract: Augmented reality (AR) devices, systems and methods are provided to argument captured images of objects of interest. Image data can be obtained for an object of interest by an imaging device of an ear-worn device worn by a user. Augmenting information is generated to augment onto an image of the object. The augmented image is adjusted based on the detection on whether the object is in a field of view (FOV) of the imaging device.

Abstract: The disclosure describes systems (2) of navigating a hazardous environment (8). The system includes personal protective equipment (PPE) (13) and computing device(s) (32) configured to process sensor data from the PPE (13), generate pose data of an agent (10) based on the processed sensor data, and track the pose data as the agent (10) moves through the hazardous environment (8). The PPE (13) may include an inertial measurement device to generate inertial data and a radar device to generate radar data for detecting a presence or arrangement of objects in a visually obscured environment (8). The PPE (13) may include a thermal image capture device to generate thermal image data for detecting and classifying thermal features of the hazardous environment (8). The PPE (13) may include one or more sensors to detect a fiducial marker (21) in a visually obscured environment (8) for identifying features in the visually obscured environment (8).
