Dialogue-Assisted Visual Environment for Geoinformation (DAVE_G)
Current computing systems restrict human-computer interaction to one mode at a time and are designed with an assumption that use will be by individuals (rather than groups), directing (rather than interacting with) the system. To support the ways in which humans work and interact, a new paradigm for computing is required that is multimodal, rather than unimodal, collaborative, rather than personal, and dialogue-enabled, rather than unidirectional. We outline a conceptual approach toward natural, multimodal, multiuser dialogue-enabled interfaces to geographic information systems (DAVE_G) that make use of large-screen displays and virtual environment technology. Watch a demonstration of DAVE_G and a Multimodal Tablet GIS demonstration
Building ESTAT in GeoVISTA Studio:
Building ESTAT in GeoVISTA Studio
(.avi video clip - if you have trouble, try downloading this)
Description: This clip illustrates the steps taken to build ESTAT in GeoVISTA Studio. The process starts by adding 6 Java Beans to the Studio design box: one bivariate map, one scatterplot, two parallel coordinate plots (one used as a PCP and the other used as a time-series graph), one data loader, and one coordinator. Then, beans are wired together so that all of the graphic components support coordinated user action and one of the PCPs works as a time series plot (by being linked to the data loader's time series import hook, rather than directly to the coordinator).
Using ESTAT to Explore Cancer Data
- This clip focuses on exploration of bivariate data relationships using the bivariate map and scatterplot tools. The clip begins by illustrating mouse-over ID of places in the scatterplot, then illustrates linked brushing from the scatterplot to the map and PCP, then from the map to the other components. Then, the excentric labeling component is illustrated (this is a free component obtained from http://www.cs.umd.edu/hcil/excentric/). Finally, a fisheye lens applied to the map is demonstrated. This component is from an open source toolkit by Jean-Daniel Fekete called The InfoVis Toolkit, available from: http://www.lri.fr/~fekete/ (trouble viewing? try this)
- This clip emphasizes the use of brushing on the PCP. The variables depicted are mercury and benzene emissions, stomach cancer, and per capita income. The first scene shows that Los Angeles county has the highest benzene emissions (and third highest mercury emissions). The interaction demonstrated shows a two step selection. First, those counties with benzene emission above the interquartile range are brushed. Then, all the remaining counties with stomach cancer mortality rates within or below the interquartile range are removed from the display. The counties that remain are those that are both high in stomach cancer mortality and high in bezine emission. The map illustrates that these counties are concentrated in the northeast industrial belt and in the west. The preponderance of dark gray counties indicates that the counties are also high in mercury emissions. (trouble viewing? try this)
- This clip is also focused on the PCP. The initial scene shows that the county with highest male stomach cancer mortality for the time period is Petroleum, MN. The rest of the video clip illustrates the use of box plots, summary lines (one for each state), and axis focusing and rescaling. The tools are used to identify states in the U.S. having stomach cancer mortality rates for men that are (a) lower than the interquartile range as depicted on the box plot for stomach cancer (mostly in the southeast) and (b) above the interquartile range (mostly in the northeast and upper mid-west/great plains). The map and scatterplot depict the relation between stomach cancer mortality and mercury emissions aggregated by county. When the PCP is focused in on the high stomach cancer mortality counties, the bivariate map illustrates that those in the northeast are also high in mercury emission (indicated by the dark gray that represents high values on both variables) while the mid-west/great plains counties do not exhibit this relationship.

- This video demonstration illustrates the visual analysis of a multivariate dataset using ESTAT. The dataset explored here is made up of lung cancer mortality counts and rates and a variety of socioeconomic, environmental, and educational variables, all aggregated to the county level across the continental United States. The demonstration shows how visualization and linked tools in ESTAT can be used to quickly and broadly to investigate the dataset for geographic variations in any of the variables. It then uses, as an example, differences in mortality by gender to illustrate a deeper multivariate analysis of the data. The analysis reveals some interesting associations between male lung cancer mortality and other variables that generate deeper questions and warrant further analysis with ESTAT, and with traditional epidemiological studies.
