Visual languages mediate human and computer interaction. Advances in commodity hardware and software, including touch-sensitive surfaces and vision processing systems, are enabling fundamental enhancements to this mediation through sketch and gesture recognition. More formal visual languages allow experts to accurately specify complex systems, such as software architecture or chemical molecules. A visual language can also encompass complex human-computer interaction such as navigating a set of semantically linked videos. Combining aspects of art, engineering, and science, visual computing involves the design and engineering of visual interactions and the analysis of these interactions in terms of semantics, efficiency, aesthetics, pleasure, emotion, engagement, immersion, collaboration, and culture. For this year's special theme we request high-quality submissions on visual languages and visual computing techniques that enhance digital modeling and fabrication and leverage 3D printing innovations. In addition to the special theme, we continue to solicit papers on all aspects and approaches to visual languages and computing, including interactive visual computing, computer-empowered visual computing, human-empowered visual computing, transformation algorithms for visual computing, and visual languages for visual computing.
