1. A system for conveying body movements, the system comprising: an optical capturing unit configured to capture a video feed of an individual, the video feed having a first signal portion and a second signal portion; a library of data mapping body movements to discrete instructions associated with the body movements, wherein the instructions correspond to computing system operations; and a video processing subsystem coupled to the optical capturing unit and configured to: in response to the optical capturing unit capturing the first portion of the video feed: determine, in the first portion of the video feed, a first position of a particular body part of the individual, in response to the optical capturing unit capturing the second portion of the video feed: determine, in the second portion of the video feed, a second position of the particular body part of the individual, and ascertain, based on the determined first position and the determined second position, a movement of the particular body part between the first and second positions; and identify a discrete instruction associated with the ascertained body movement from the data in the library at least in part by comparing the ascertained body movement to data in the library.
