“…This led to research on heuristics to resolve this, both, during design time [Che95, CH95, CCH96] and during re‐evaluation (under changed parameter values) [Kri95, AMP00]. Robustness in design has been explored using geometric constraints [BH11], and explicit user input [Gir01, PPG96]. These works successfully provide persistent and unique names to geometric entities (termed the ‘naming problem').…”

Parametric computer‐aided design (CAD) enables description of a family of objects, wherein each valid combination of parameter values results in a different final form. Although Graphical User Interface (GUI)‐based CAD tools are significantly more popular, GUI operations do not carry a semantic description, and are therefore brittle with respect to changes in parameter values. Programmatic interfaces, on the other hand, are more robust due to an exact specification of how the operations are applied. However, programming is unintuitive and has a steep learning curve. In this work, we link the interactivity of GUI with the robustness of programming. Inspired by programme synthesis by example, our technique synthesizes code representative of selections made by users in a GUI interface. Through experiments, we demonstrate that our technique can synthesize relevant and robust sub‐programmes in a reasonable amount of time. A user study reveals that our interface offers significant improvements over a programming‐only interface.

“…Features of new elements can be defined in terms of the parameters of existing elements. When the user changes a parameter, all commands in the script that depend on it are automatically re-run -for example, if the user resizes the main cylinder of a screw, the screw head defined to be 1.5x wider will automatically be resized as well [14]. Grouping and simple repetition are also generally supported, and the EBP system [29] additionally implemented programming by demonstration interactions to specify loops and conditionals.…”

Direct manipulation interfaces provide intuitive and interactive features to a broad range of users, but they often exhibit two limitations: the built-in features cannot possibly cover all use cases, and the internal representation of the content is not readily exposed. We believe that if direct manipulation interfaces were to (a) use general-purpose programs as the representation format, and (b) expose those programs to the user, then experts could customize these systems in powerful new ways and non-experts could enjoy some of the benefits of programmable systems.In recent work, we presented a prototype SVG editor called SKETCH-N-SKETCH that offered a step towards this vision. In that system, the user wrote a program in a general-purpose lambda-calculus to generate a graphic design and could then directly manipulate the output to indirectly change design parameters (i.e. constant literals) in the program in real-time during the manipulation. Unfortunately, the burden of programming the desired relationships rested entirely on the user.In this paper, we design and implement new features for SKETCH-N-SKETCH that assist in the programming process itself. Like typical direct manipulation systems, our extended SKETCH-N-SKETCH now provides GUI-based tools for drawing shapes, relating shapes to each other, and grouping shapes together. Unlike typical systems, however, each tool carries out the user's intention by transforming their general-purpose program. This novel, semi-automated programming workflow allows the user to rapidly create highlevel, reusable abstractions in the program while at the same time retaining direct manipulation capabilities. In future work, our approach may be extended with more graphic design features or realized for other application domains.

Abstract:A promising approach to Computer-Aided Design of User Interfaces (CADUI) is Programming by Example, where an interface designer demonstrates the behavior of an interface by presenting concrete examples and demonstrating how the system should behave on those examples. It lets the user interface designer "play end-user", simulating what an end-user would see and do. A software agent records the steps of the user interface and generalizes a program that can be used in analogous situations in the future. The popular genre of so-called Interface Builders can be seen as a "poor-man's" Programming by Example. It is now time to extend such systems so that behavior as well as appearance can be specified by example.
