1. A computing system for facilitating communication with one or more hearing-impaired viewer, the computing system comprising: at least one hardware processor; and one or more hardware storage device having stored computer-executable instructions that are executable by the at least one hardware processor, and that configure the system to facilitate communications to one or more user, including computer-executable instructions that configure the computer system to perform at least the following: obtain detected focus information associated with a head-mounted device to identify one or more particular items that are viewable by a viewer wearing the head-mounted device; obtain video of sign language being signed by a signer, the sign language corresponding to the one or more particular items viewable by the viewer; visually enhance the obtained video of sign language with one or more modification in such a manner that a subsequent rendering of the obtained video of sign language will be rendered as a modified video presentation having the one or more modification; and transfer the modified video presentation to one or more display system on the head-mounted device, the display system configured to display the modified video presentation on a display portion of the head-mounted device using optical properties of a transparent material incorporated into the display system, the display system displaying the modified video presentation to a viewer on the display portion simultaneously while the viewer is viewing the one or more particular items corresponding to the sign language of the obtained video, the sign language being displayed concurrently while the one or more particular items are viewable by the viewer through the head-mounted device, so as to enable the viewer to view the sign language from the modified video presentation and the one or more particular items concurrently, wherein positioning of the modified video presentation on the display portion of the head-mounted device is at least partially based on the detected focus information.
2. The computing system of claim 1 , wherein the modified video presentation is rendered simultaneously with a different video presentation that includes the one or more items, the modified video presentation and the different video presentation being rendered together as a single blended presentation.
