Visualizing Personal Histories A Workshop,July 21-22, 1997 Ben Shneiderman Overview and Workshop Summary Personal history records are central to decision-making in medicine, hiring, personnel reviews, life insurance, and educational admissions. These records are increasingly computerized bur onscreen presentations are often more difficult to traverse than paper records. Physicians often fail to review online patient histories and bank officials reject loan applicants rather than digging into an electronic financial history. Visual overviews may enable dramatic improvements in decision-making, much as graphical user interfaces have contributed to desktop publishing, directory browsing, and air traffic control. Visual presentations o f personal histories and biographies offer new research challenges in: ¢ temporal visualization and graphical presentation ¢ information coding by color, size, position, etc. ¢ user interface controls ¢ overview+detail view or focus+context design ¢ temporal search and browsing ¢ data structures and algorithms ¢ importing and exporting o f data ¢ integration of image, audio, and video data ¢ privacy protection and data validation. T h e University o f Maryland H u m a n Computer Interaction Laboratory (HCIL) has been working on this t o p i c for three years.
