'I Hear the Pattern' Interactive Sonification of Geographical Data Patterns (2004)
(2005)
In this paper we describe our investigation of using interactive sonification (non-speech sound) to present the geographical distribution pattern of statistical data to vision impaired users. We first discuss the design ...
Extending the Utility of Treemaps with Flexible Hierarchy (2004)
(2005)
Treemaps is a visualization technique for presenting hierarchical information on two dimensional displays. Prior implementations limit the visualization to pre-defined static hierarchies. Flexible hierarchy, a new capability ...
Broadening Access to Large Online Databases by Generalizing Query Previews (2000)
(2005)
Companies, government agencies, and other types of organizations are making their large databases available to the world over the Internet. Current database front-ends do not give users information about the distribution ...
Interactive Pattern Search in Time Series (2004)
(2005)
The need for pattern discovery in long time series data led researchers to develop algorithms for similarity search. Most of the literature about time series focuses on algorithms that index time series and bring the data ...
Improving Accessibility and Usability of Geo-referenced Statistical Data (2003)
(2005)
Several technology breakthroughs are needed to achieve the goals of universal accessibility and usability. These goals are especially challenging in the case of geo-referenced statistical data that many U.S. government ...
An Information Architecture to Support the Visualization of Personal Histories
(1997)
This paper proposes an information architecture for personal history data and describes how the data model can be extended to a runtime model for an intuitive visualization using graphical timelines. Our information ...
Immediate Usability: Kiosk design principles from the CHI 2001 Photo Library (2001)
(2005)
This paper describes a novel set of design principles and guidelines for ensuring the immediate usability of public access systems. These principles and guidelines were formulated while developing PhotoFinder Kiosk, a ...
Immediate Usability: A Case Study of Public Access Design for a Community Photo Library (2003)
(2005)
This paper describes a novel instantiation of a digital photo library in a public access system. It demonstrates how designers can utilize characteristics of a target user community (social constraints, trust, and a lack ...
New Approaches to Help Users Get Started with Visual Interfaces: Multi-Layered Interfaces and Integrated Initial Guidance (2003)
(2005)
We are investigating new ways to help users learn to use public access interactive tools, in particular for the visual exploration of government statistics. Our work led to a series of interfaces using multi-layered design ...
Interface and Data Architecture for Query Preview in Network Information Systems
(1997)
There are numerous problems associated with formulating queries on networked information systems. These include data diversity, data complexity, network growth, varied user base, and slow network access. This paper proposes ...
