US Patent 9836652 Showing danger areas associated with objects using augmented-reality display techniques

A mechanism is provided for indicating an area of an object that is considered dangerous to a user via a head mounted display (HMD) system. The object being used by the user and one or more areas of the object that are considered dangerous are identified. Responsive to identifying one or more areas of the object that are considered dangerous, an overlay for each of the one or more areas of the object that are considered dangerous is generated. The overlay for each one or more areas of the object that are considered dangerous is displayed via a display layer of the HMD system so that the one or more areas of the object that are considered dangerous are identified as an overlay to the object that is being seen by the user through the HMD system.
