Projects
| NetVis | (Fall 2007 - Present) |
|
|
Designed and implemented network visualization components to support visual analytics in Business Intelligence such as market basket analysis. (written in Flex2/ActionScript3) |
| C-Group | (Spring 2007 - Present) |
|
|
Designed and implemented C-Group, A visual analytic tool for pairwise analysis of dynamic group membership in temporal social network. C-Group provides users with a flexible interface for defining groups interactively, and supports two novel visual representations of the evolving group memberships. This flexibility gives users alternate views that are appropriate for different network sizes and provides users with different insights into the grouping behavior. (written in C#) |
| GeoDDupe | (Spring 2007 - Fall 2007) |
|
|
Designed and implemented GeoDDupe, an interactive tool which effectively combines automatic data mining algorithms for geospatial entity resolution with a novel network visualization supporting users' resolution analysis and decisions. |
| D-Dupe | (Fall 2006 - Present) |
|
|
Designed and implemented D-Dupe2.0, an interactive tool for entity resolution in social networks. D-Dupe is an interactive tool that combines data mining algorithms for entity resolution with a task-specific network visualization. Users cope with complexity of cleaning large networks by focusing on a small subnetwork containing a potential duplicate pair. The subnetwork highlights relationships in the social network, making the common relationships easy to visually identify. (written in C#) |
| NetLens | (Spring 2005 - Fall 2006) |
|
|
Designed and implemented NetLens, an interactive network visualization system that enables users to explore data incrementally and refine their queries iteratively using the Content-Actor network data based interface. NetLens offers rich support for real tasks that are typically composed of a sequence of low level tasks, which are hard to be handled in traditional node-link diagram visualizations. NetLens is general and scalable in analyzing various kinds of network data such as email archives, photo collections, digital libraries, and even case law.

| IDFinder | (Spring 2004 - Spring 2005) |
|
|
Designed and implemented IDFinder, a prototype information visualization tool to facilitate microdata re-identification process. The main goal of this project is to help users (researchers working on disclosure avoidance research) visually identify any microdata records that are at risk of disclosure so that they can be masked before released to the public. (Written in C#) |
| NeoPhotoMesa | (Spring 2004 - Present) |
|
|
Designed and implemented NeoPhotoMesa, a commercial tool (http://www.windsoninterfaces.com) for managing personal digital photo library by combining PhotoFinder (http://www.cs.umd.edu/hcil/photolib) with PhotoMesa (http://www.photomesa.com). PhotoMesa is a program that lets users browse, annotate, and search their digital images. It allows users to view multiple directories of images at once, and uses simple navigation commands to smoothly zoom in and out using zoomable user interface. PhotoMesa also supports more advanced and innovative mechanism for organizing, annotating, and searching photos. (Written in C#) |
| MediaFinder | (Spring 2002 - 2003) |
|
|
MediaFinder,
a prototype interactive tool built to investigate the use of Semantic Regions for exploring and managing personal media data. Semantic Regions is an innovative way for users to construct display representations of their conceptual models by drawing regions on 2D space and specifying the semantics for each region. Then users can apply personal categorizations to personal media data using the fling-and-flock metaphor. This allows personal media to be dragged to the spatially-organized display and automatically grouped according to time, geography, family trees, groups of friends, or other spatially-organized display representations of conceptual models. (Written in Visual Basic.NET) |
| Integrated Initial Guidance | (Summer 2002 - 2003) |
|
|
Designed and implemented a new way to help users learn to use public access visual data mining tool dynamap as a part of NSF digital government project. Integrated Initial Guidance provides help within the working interface, right at the start of the application. Using the metaphor of "sticky notes" overlaid on top of the functional interface it locates the main widgets and demonstrates their manipulation and explains the resulting actions using preset activations of the interface. (Written in Visual Basic 6.0) |
| Multimedia Bulletin Board | (Summer 2001) |
|
|
Designed and implemented Multimedia Bulletin Board as a prototype of an asynchronous communication system that enables rich communication and collaboration among users of multimedia objects (Written in Visual Basic 6.0) |
| PhotoFinder Kiosk | (Fall 2000 - Spring 2001) |
|
|
Designed and implemented a PhotoFinder Kiosk version with network support and group annotation for demonstration at the ACM CHI 2001 conference in Seattle (Apr.2 - Apr.5, 2001) (Written in Visual Basic 6.0, connected to MS SQL Server) |
| PhotoFinder | (Fall 1999 - Fall 2000) |
|
|
Designed and implemented the PhotoFinder prototypes as part of research effort on Personal Photo Libraries with the support of Intel, IBM and Microsoft. Some of the efforts in this project include innovative ways of addressing such tasks as different ways input, cataloging image metadata, searching and browsing for images (Written in Visual Basic 6.0). |
| Zquote | (Spring 1999) |
|
|
Designed and implemented Zquote(Interactive visualization navigation of stock market information) as a prototype of a zommable stock information browser that dynamically navigates, compares and extracts useful information from the stock market. (Written in JAVA) |
| PDA Kiosk (Fall 2000) | Designed and implemented the interface on thePDA that assists visitors in their searches at the Computer Science Department. The client tool was written to match the capabilities of the new Compaq iPAQ H3600 (OS: Windows CE) |
| VIPER (Spring 1993 - Fall 1994) | Engaged in a research project "A Knowledge-based Industrial Visual Inspection System" with the support of Hyundai Electronics Co. and the Ministry of Trade and Industry in Korea. |
