1. A system comprising: a first computing device, the first display device comprising: a first processor; a first camera coupled to or operable by the first processor, the first camera configured to capture a reference image and a current image of a view field; a display configured to display the current image; a depth acquisition module coupled to or operable by the first processor, the depth acquisition module configured to acquire geometry information of the view field; and a first transceiver coupled to or operable by the first processor, the first transceiver configured to: transmit the reference image and the geometry information; and receive annotation information to be displayed on the first display; and a second computing device communicatively connectable with the first computing device, the second computing device comprising: a second processor; a user-operable input device coupled or operable by to the second processor; a second transceiver coupled or operable by to the second processor, the second transceiver configured to receive the reference image and the geometry information from the first computing device; an annotation module coupled to or operable by the second processor to receive input via the input device and determine at least one annotation based at least in part on the input; and a second display coupled to or operable by the second processor, the second display configured to display the reference image and to display the at least one annotation superimposed over the reference image; wherein: the second transceiver is further configured to transmit reference frame data to the first computing device, the reference frame data associated, at least in part, with the reference image, the geometry information, and the at least one annotation; and the first computing device is further configured to display the at least one annotation anchored to the displayed current image based on the received reference frame data.
