Research Areas
The HCIL has conducted a broad range of research over the years, and continues to pursue several areas in depth. All projects are listed below, and are grouped by area:
Current Projects
Biodiversity Information Visualization (TaxonTree, DoubleTree, EcoLens, LepTree)
Interfaces for online biodiversity and ecological databases, featuring incremental tree and graph browsing, in-context search results, coupled views, and readable labels.
Bioinformatics Visualization
We developed information visualization tools for gene expression data analysis, including mosaics, hierarchical clustering, parallel coordinates, treemaps, and scattergrams.
BIRD Note-taking system
Allows the integration of dynamically captured presentation materials with student notes.
Children as Design Partners (Intergenerational Design Teams)
Children, ages 7-11, work with HCIL faculty/staff/students after school and over the summer to create new technolgies for children.
Classroom of the Future
Mobile and embedded technologies are created in partnership with pre-school children and teachers at the Center for Young Children.
Community Response Grids
The 911.gov system would rely on the Internet and the mobile communication devices to allow citizens to receive and submit information about significant homeland security community problems. Based on lessons from recent natural catastrophes and the terror attacks of 9/11, telephone, radio, and television-based emergency response systems cannot meet all of the emergency response needs of communities. The combination of mobile telecommunications devices and the Internet in 911.gov, however, has the potential to provide higher capacity and more effective service, as well as create interactive communication mechanisms that can reach many more citizens and government officials simultaneously.
Dickinson Electronic Archives
A website devoted to the study of Emily Dickinson, her writing practices, writings directly influencing her work, and critical and creative writings generated by her work.

Dual/Multi Display Electronic Readers
Existing electronic reading devices don't adequately support the different types of reading people perform. We explored interface designs for a two-screen reading device that allow it to improve the reading experience. To perform our exploration we created a series of prototypes, ranging from low-fi paper to a fully-functioning electronic reading device with two detachable, motion-sensitive faces
Electronic Voting Systems
Evaluation of usability, preference, accuracy and confidence in new voting system technologies and verification systems.

children who speak different languages and are from different
cultures to come together using activities related to books in
the ICDL as common ground.
International Children's Digital Library
A library that provides free access to children's books from around the world. By ensuring access to books from many cultures and in diverse languages, we foster a love of reading, a readiness to learn, and a response to the challenges of world illiteracy.
