Swire

Sketches and real-world user interface examples are frequently used in multiple stages of the user interface design process. Unfortunately, finding relevant user interface examples, especially in large-scale datasets, is a highly challenging task because user interfaces have aesthetic and functional properties that are only indirectly reflected by their corresponding pixel data and meta-data. This paper introduces Swire, a sketch-based neural-network-driven technique for retrieving user interfaces. We collect the first large-scale user interface sketch dataset from the development of Swire that researchers can use to develop new sketch-based data-driven design interfaces and applications. Swire achieves high performance for querying user interfaces: for a known validation task it retrieves the most relevant example as within the top-10 results for over 60% of queries. With this technique, for the first time designers can accurately retrieve relevant user interface examples with free-form sketches natural to their design workflows. We demonstrate several novel applications driven by Swire that could greatly augment the user interface design process.
