Visual communication through graphical or sign languages has long been conducted among human beings of different backgrounds or cultures, and in recent decades between human and machine. In today's digital world, visual information is typically encoded with various metaphors commonly used in daily life to facilitate rapid comprehension and easy analysis during the communication process. Visual information communication generally encompasses information visualization, graphical user-interfaces, visual analytics, and visual languages. It has been successfully employed in knowledge discovery, end-user programming, modeling, rapid systems prototyping, education, and design activities by people of many disciplines including architects, artists, children, engineers, and scientists. In addition, visual information is increasingly being used to facilitate human-human communication through the Internet and Web technology, and electronic mobile devices. The 6th International Symposium on Visual Information Communication and Interaction (VINCI 2013) provides an international forum for researchers and industrial practitioners to discuss the state of the art in visual communication theories, designs, and applications. VINCI has been previously held in Shanghai (VINCI'2008), Sydney (VINCI'2009), Beijing (VINCI'2010), Hong Kong (VINCI'2011), and Hangzhou (VINCI'2012). VINCI '2013 will be held on 17-18 August in Tianjin, China.
