Abstract: An augmented reality system that includes processors and storage devices storing instructions. The instructions configure the processors to perform operations. The operations include identifying a writing object in a video feed being displayed in an augmented reality viewer, identify a tip of the writing object based on a contour of the writing object, and tracking movements of the tip in the augmented reality viewer. The operations may also include generating a virtual file, the virtual file storing the tracked movements and generating a text file by performing an image recognition operation associating the tracked movements stored in the virtual file with one or more characters.

Abstract: An example laser assembly for a laser printer may include a plurality of lasers to emit respective photons; a prism to redirect the respective laser beams emitted from the plurality of lasers toward a collimator lens of the laser printer to generate a photon beam; and one or more processors to: determine a timing schedule for individually activating the plurality of lasers based on a resolution setting of the laser printer, and when printing at a resolution corresponding to the resolution setting, control activation of each of the plurality of lasers to emit the respective photons according to the timing schedule to form the photon beam.
