Designers Need End-User Software Engineering

This position paper for the End-User Software Engineering workshop outlines three systems that employ end user programming for designers: a constraint-based design environment; a sketch recognition interface for knowledge based systems, and a physical programming environment for building modular robots

Research in constraint-based layout, visualization, CAD, and related topics : a bibliographical survey

The present work compiles numerous papers in the area of computer-aided design, graphics, layout configuration, and user interfaces in general. There is nearly no conference on graphics, multimedia, and user interfaces that does not include a section on constraint-based graphics; on the other hand most conferences on constraint processing favour applications in graphics. This work of bibliographical pointers may serve as a basis for a detailed and comprehensive survey of this important and challenging field in the intersection of constraint processing and graphics. In order to reach this ambitious aim, and also to keep this study up-to-date, the authors appreciate any comment and update information

CoDraw “Graphical Constraints in CoDraw”

Constraint based draw programs require users to understand and manage relationships between drawing elements. By establishing constraint relationships among elements the user effectively programs the drawing's behaviour. This programming task requires a more sophisticated visual interface than conventional draw programs provide. Users must have available - in a convenient format - information about the structure of the constraints that determine the drawing's interactive edit behaviour. This format must support editing and debugging. CoDraw is a constraint based drawing program that can be interactively extended by its users. This paper describes the CoDraw program and its programming interface.
