Deconstructing CHI

When we make reference to ``CHI'' (Computer Human Interaction) we call attention to the boundary between humans and computers --- CHI becomes a self-fulfilling prophecy, emphasizing this boundary. A goal of `existential computing' is to eliminate this artificial (unnecessary) boundary by ``becoming'' the computer, rather than merely interfacing to it.

An example of an existential user interface is the author's `finger mouse'[7] (based on `WearCam' as in input device). (See Fig 1),

(c) What wearer sees through the glasses: outline of the object that denotes path of moving finger around in the space between the camera (taking the role of eye) and the object.
