Tosupport designer exploration of alternatives, Scout introduces high-level constraints based on design concepts (e.g.,~semantic structure, emphasis, order) and formalizes them into low-level spatial constraints that a solver uses to generate potential layouts. Prior constraint-based layout systems use low-level spatial constraints and generally produce a single design. We present Scout, a system that helps designers rapidly explore alternatives through mixed-initiative interaction with high-level constraints and design feedback. All these features permit GUI developers to focus more on the overall UI design.Īlthough exploring alternatives is fundamental to creating better interface designs, current processes for creating alternatives are generally manual, limiting the alternatives a designer can explore. This displays the layout at its minimum and in an enlarged size, which allows visualizing potential resize issues directly. Finally, to aid designers in creating layouts with good resize behavior, we propose a novel automatic layout preview.

Furthermore, we discuss how our innovations can be combined with manual constraint editing in a sound way. To achieve that, we present a new algorithm that automatically generates the constraints necessary to keep a layout non-overlapping. ALE guarantees that all edit operations lead to sound specifications, ensuring solvable and non-overlapping layouts. We give a detailed description of ALE's edit operations, which do not require direct constraint editing. We present a new GUI builderthe Auckland Layout Editor (ALE)that addresses these challenges by enabling GUI designers to specify constraint-based layouts using simple, mouse-based operations. This poses challenges for GUI builder tools, which ideally should address these issues automatically.
However, they are also more complex and their layouts are prone to problems such as over-constrained specifications and widget overlap. Constraint-based layout managers are among the most powerful. Layout managers are used to control the placement of widgets in graphical user interfaces (GUIs).
