“…Geometric constraints, particularly over-and underconstrained configurations, can be difficult to solve and the results can be difficult to anticipate. Wybrow et al [30] compared one-way and multi-way constraints for diagram editing. One-way constraints are easy to understand but are limited.…”

“…Instead, our beautification interface focuses on automatic inference of geometric constraints, and thus only very few edits on constraints (after roughly placing elements) are needed to achieve a desired layout. Note that our current system performs onceoff alignment only and does not maintain inferred constraints during subsequent editing [31]. Recently Zeidler et al [32] introduce a novel layout preview but focus on the resizing behavior of a constraint-based layout during the design phase.…”

Automatic global beautification methods have been proposed for sketch-based interfaces, but they can lead to undesired results due to ambiguity in the user's input. To facilitate ambiguity resolution in layout beautification, we present a novel user interface for visualizing and editing inferred relationships. First, our interface provides a preview of the beautified layout with inferred constraints, without directly modifying the input layout. In this way, the user can easily keep refining beautification results by interactively repositioning and/or resizing elements in the input layout. Second, we present a gestural interface for editing automatically inferred constraints by directly interacting with the visualized constraints via simple gestures. Our efficient implementation of the beautification system provides the user instant feedback. Our user studies validate that our tool is capable of creating, editing and refining layouts of graphic elements and is significantly faster than the standard snap-dragging and command-based alignment tools.

“…More recent active projects that support (one-way) data-flow constraints include the OpenLaszlo framework [22] for developing rich Internet applications. Constraints in these systems are mainly used for layout where the simpler one-way constraints are rather standard, e.g., in many diagram drawing tools [33]. Based on extensive experience with the Amulet system, its authors conclude that it is unlikely that constraint systems will ever be used for much other than layout [36].…”

User interfaces for modern applications must support a rich set of interactive features. It is commonplace to find applications with dependencies between values manipulated by user interface elements, conditionally enabled controls, and script record-ability and playback against different documents. A significant fraction of the application programming effort is devoted to implementing such functionality, and the resulting code is typically not reusable.This paper extends our "property models" approach to programming user interfaces. Property models allow a large part of the functionality of a user interface to be implemented in reusable libraries, reducing application specific code to a set of declarative rules. We describe how, as a by-product of computations that maintain the values of user interface elements, property models obtain accurate information of the currently active dependencies among those elements. This information enables further expanding the class of user interface functionality that we can encode as generic algorithms. In particular, we describe automating the decisions for the enablement of user interface widgets and activation of command widgets. Failing to disable or deactivate widgets correctly is a common source of user-interface defects, which our approach largely removes.We report on the increased reuse, reduced defect rates, and improved user interface design turnarounds in a commercial software development effort as a result of adopting our approach.
