GSI 2017 - International Symposium Glyphs: Shapes, Icons, Text and Imagery in Visualization

Point markers such as text labels, icons, pictographs, thumbnail images and shapes are small independent visual objects that depict data discretely placed in space that utilize elements of visual channels to convey information. Each of these markers have different conventions and constraints which can enable different kinds of benefits in visualizations ranging from infographics (e.g. USA Today style charts), to statistical graphics (e.g. Isotype) to rich multi-dimensional markers (e.g. icons on scatterplots, imagery on nodes in graphs, text labels with multiple font attributes on maps, Chernoff faces, etc.), to groups of glyphs or compound glyphs with associated grammars to convey more complex information (e.g. pictograph on a triangular background shape typically indicates a warning for the associated pictograph when used for road signs). Glyph-based approaches to encoding data pre-exist information visualization extending back to early language, early cartography, early typography and early information graphics.
The increasing potential value of glyphs to convey data in information visualization is driven by a confluence of factors, including:
1) Much higher pixel resolutions in the newest devices, enabling much more fine detail in markers,
2) The potential to embed many dimensions of data in glyphs to create for more effective representations or higher densities of complex information
3) The potential for novel representations and new applications.
The use of glyphs within information visualization open a number of research questions such as:
What are the visual channels that can be used to encode information in glyphs, how can they be combined.
What visualization opportunities exist beyond icons and pictographs, such as shapes, fonts, text, imagery, video, etc.
How can fonts and text be utilized to convey more information than as labels
Use of optical channels such as blur, motion, shadow in glyph design
What kinds of placements and interactions are uniquely applicable to glyphs
How should glyphs be designed, what criteria should be used to evaluate glyphs
How can glyphs be combined or sequenced together in information visualization
What compelling applications for glyph-based visualization exist
How can pictographic glyphs, abstract glyphs and text glyphs be used together
