||Using the familiar metaphor of timelines, LifeLines takes advantage of our ability to visually analyze information-abundant displays, and facilitates access to the details in the medical patient record. A Java user interface presents a one-screen overview. Problems, diagnoses, test results, or medications can be represented as dots or horizontal lines. Zooming provides more details; line color and thickness illustrate relationships or significance. The visual display acts as a giant menu, giving direct access to the details.
