Abstract: A method of permitting an individual to virtually try on a piece of jewelry using augmented reality comprises generating image data associated with the individual and a trial implement. The trial implement is positioned about a portion of the individual. The image data can be generated using one or more image sensors. The method further comprises analyzing the image data to identify the trial implement. The method further comprises causing an electronic display device to display a real-time video of a virtual version of the individual and a virtual version of the piece of jewelry on the individual. The virtual version of the piece of jewelry is positioned relative to the virtual version of the individual based at least in part on the identified trial implement.

Abstract: A motion tracking element for an oral hygiene element such as a toothbrush. The motion tracking element may be detachably coupled to the oral hygiene element. The motion tracking element may include a body having an outer surface, a portion of the outer surface having a pattern that includes a plurality of indicators with a non-circular shape. The indicators may be flush with and form part of the outer surface. A plurality of visual markers may be located on the outer surface, each of the visual markers having a circular shape. The plurality of visual markers may be formed integrally with the body. A method for estimating a pose of an oral hygiene device may be achieved using the motion tracking element.

Abstract: A method for estimating a pose of an oral hygiene device including a pattern and a plurality of groups of visual markers relative to a location includes (i) receiving image data reproducible as an image of at least a portion of the oral hygiene device; (ii) analyzing the image data to identify a region of interest within the image; (iii) identifying, using at least one of the one or more processors, all candidate visual markers within the region of interest; (iv) obtaining a first proposed three-dimensional pose of the oral hygiene device; (v) validating the first proposed three-dimensional pose of the oral hygiene device; and (vi) obtaining a second proposed three-dimensional pose of the oral hygiene device based on the validated first proposed three-dimensional pose.
