IS&T CONFERENCE ON HUMAN VISION AND ELECTRONIC IMAGING-- The International Conference on Perception, Cognition and Electronic Media

I founded HVEI in order to build a multidisciplinary community of scientists and technologists working at the intersection between perception, cognition, and emerging electronic technologies.  Working with my co-chairs, Jan Allebach, Thrasos Pappas, Mike Brill, Scott Daly and Huib de Ridder, the topics have evolved over the years, including early-vision models, digital coding, image quality, attention, visualization, multisensory interfaces, brain imaging, art and design. 


Color in Visualization and UI Design-- why perception matters

The same data with two different color maps.  The rainbow colormap (left) obfuscates the features in this visualization of Florida; the perceptual colormap (right) provides a more faithful representation of the data.  Rogowitz and Treinsh, 1998.

In the Higgs-Boson experiment, two specially-constructed
beams of particles were set to collide in front of a particle detector.  All four panels show the mass (GeV/C2) of  hundreds of trillions of collisions.  The hypothesized Higgs-Boson was predicted to have a mass of 125-127 Giga Electron Volts.   The top left panel uses a rainbow colormap to represent the  mass across the detector.  The data were log transformed (bottom left), then a colormap with monotonic luminance was used (bottom right), and, in the top right, the mass was redundantly mapped onto a height, producing a visualization that clearly shows the mass signature of the Higgs BosonRogowitz and Couet, CERN 2013

Interactive Visualization - the Visualization and Visual Analysis  (ViVA) Workbench
At IBM Research, my group developed an interactive visualization and analysis package, which we licensed to SPSS and used in IBM offerings, such as FAMS.  ViVA offers over 20 linked visualizations, with color brushing, plus a library of over 250 mathematical functions.  Download it free from Source Forge!

Finding Patterns across Multiple Data Types

Working with Johns Hopkins University, we developed a method for linking a 3-D model of the heart with 2-D visualizations of parameters of an underlying finite element model.  A 3-d model of a heart is shown in the top left panel.  For every point in the heart, there are values of a finite element model, which are visualized in the scatterplot and histogram.  In this example, the analyst has marked two regions in the histogram, corresponding to two different ranges of the variable 'Calcium in the Subspace of the Heart Organelle' and can immediately see which areas of the 3-D heart have these values.

Although scientific software often provides complementary functions, it is difficult to create an application that supports interactive exploration across applications.  To address this problem, Naim Matasci and I have just published a paper on an architecture for sharing data between components, which we call  the Metadata mapper.  In this system, the user can identify metadata in one component (e.g., a region of interest) and corresponding regions can be highlighted in another.  Rules guide the data mapping, and the choices the user makes are constrained by the capabilities of the target component and guidance on human perception and cognition.  For example, the analyst may select a geographic region, in one application, and have all the species living in that region highlighted on a phylogenetic tree.  If the tree component can support the representation of continuous variables, then the user may select a color map to represent the number of represented species in a particular branch (clade) of the tree.  Which colormap are offered to the analyst depend on the data type and principles of magnitude and color perception.  Although this work was done in the context of bioinformatics data analysis, the principles are generalizable to any component architecture.

   (February 10, 2011)

The 2011 Conference on Human Vision and Electronic Imaging was fabulous.  I especially enjoyed the keynotes: Georges Grinstein on visualization and visual analysis opportunities, Anton Koning on 3-D medical environments, Jan Koenderink on the visual "priors" we bring to any visual experience, and Nao Tsuchiya on new research in attention and consciousness.  We'll be posting their presentations on the HVEI website.  I really enjoyed our special sessions Attention, and Perceptual challenges for bioinformatics data visualization.  The joint sessions on Stereo and Image Quality brought several communities together.  I'll be posting the charts from my short course soon.  And, thanks again to iPlant and RIT for sponsoring social events for us.

I'm working for the University of Texas, Austin's Center for Advanced Computing (TACC) on an NSF grant called iPlant.  My contribution is at the interface between plant and computer science, providing discovery tools and methods that will enable new scientific insights.  I'm participating in two working groups, one on Visualization and Visual Analysis for genome to phenome (G2P) data analysis and one on visualizing a 500,000 species tree of life.  I'm eager to hear about relevant work you are doing in these areas.
