User Interfaces for Juvenile Justice Information Systems

August 1994 - December 1996


There are two video demonstrations of this research project that are part of the 1995 Video Reports.

Sample screenshots are also available.
We have been working with the Maryland Department of Juvenile Services to design advanced user interfaces for an information system used by 600 employees. DJS is responsible for handling juvenile case referral for the entire state of Maryland. Our first step was to observe users, inteview users and managers, and survey 300 users with the Questionnaire for User Interface Satisfaction. We have refined and applied our user interface re-engineering methods to provide guidance for short-term improvements to the current system and are now turning to longer range recommendations. Our proposed interfaces use dynamic queries and starfield displays to the reveal trends and anomalies in case statistics. We are developing new techniques to visualize youth records and personal histories by showing multiple time lines with selectable markers to retrieve detailed information. For managers, we are proposing an organizational visualization tool that will allow effective navigation of large human services databases.
