Computer human interaction for image information systems

Increasingly images are being incorporated into computer-information systems, allowing faster and more reliable access to legal documents, fingerprints, medical images, and so on. But designing viable computer-human interactions (CHI) for image-information systems can be particularly difficult. This article presents an overall approach to developing viable image CHI involving user metaphors for comprehending image data, and methods for locating, accessing, and displaying computer images. Since medical-image applications involve almost all image display problems, a medical-image radiology-workstation application is used as a driving example to present critical image CHI issues.
