Foreword

The field of sketch-based interfaces and modeling (SBIM) has had a long history. Since the early 1960s, which saw the birth of interactive computer graphics through Ivan Sutherland’s Sketchpad and Jacks’ DAC-1 system at General Motors, we have seen researchers developing methods and techniques to let users interact with a computer through sketching, a simple, yet highly expressive medium. Initially, SBIM was not a field in and of itself, but a set of distinct areas where researchers from different backgrounds worked in isolation, without a real community to share ideas. Areas within SBIM included sketch-based modeling, where the goal was to easily create 3D models, and sketch-based interfaces, where the goal was to develop systems for recognizing, for example, hand-writing, command gestures, 2D diagrams, and mathematics. Today, SBIM has emerged as a subfield of computer science that blends concepts from computer graphics, human-computer interaction, artificial intelligence, and machine learning and has brought the two areas of sketching—interface and model specification—together. This synergy was spearheaded by Joaquim Jorge and John Hughes, who started the first SBIM conference in 2004. Over the years, SBIM has had some great successes (e.g., ha
