Palimpsest: A layered language for exploratory image processing ?
This paper presents a novel purely-visual programming paradigm for image manipulation with constraint semantics. The design rationale demonstrates a user-oriented approach to transition from direct manipulation to programming. The feasibility of the paradigm is illustrated with a description of system implementation and evaluation. The text-free constraint paradigm is well-suited to coming generations of visual touch interfaces.
