Aesthetics of computation : unveiling the visual machine

Abstract

This thesis presents a new paradigm for the design of visual programming languages, with the goal of making computation visible and, in turn, more accessible. The Visual Machine Model emphasizes the need for clear visual representations of both machines and materials, and the importance of continuity. Five dynamic visual programming languages were designed and implemented according to the specification of the Visual Machine Model. In addition to individual analysis, a comparative evaluation of all five design experiments is conducted with respect to several ease of use metrics and Visual Machine qualities. While formal user tests have not been conducted, preliminary results from general user experiences indicate that being able to see and interact with computation does enhance the programming process.
