Trace is a mark or line left by something that has passed or sign of evidence that something has passed. The more detailed meaning of the word “trace” can be extracted from Danielle Goldman’s article Ghoastcatching: An Intersection of Technology, Labor, and Race. The trace could be an impression left through the physical labor of the body. Consequently, when the work produced by the body is modified through digitalization, this special mark of the body disappears: “Nevertheless, there is very little trace, if any at all, of his labor, his improvisational exhaustion, once Ghostcatching becomes fully realized as a public work.” (Goldman 75) Thus, it becomes difficult to “trace” it back to its origins, as the digitalized, publicized image of the body loses its characteristic identity.
