RESEARCH AND SCHOLARLY INTERESTS
Recent activities are an extension of earlier efforts in developing computer aided instructional packages using audio narrations or text annotations of dissection images or atlas pictures. Current activities involve two major thrusts: exploring productive uses of the world wide web in teaching, and use of three-dimensional computer models in the illustration of anatomy. A collection of three-dimensional (3-D) models derived from the photographic, CT or MRI data of the Visible Human Project is being developed in collaboration with Dr. John Stewart. Manipulatable virtual reality modeling language (VRML) presentations with or without annotations will be posted via WWW allowing appreciation of views from many different perspectives, together with relationships of surrounding structures. Impact on learning of manipulability and 3-D viewing will be evaluated.
A second interest is in medical informatics. We are participating in the evaluation of Cornelius Rosse's Digital Anatomist Foundational Model, and the Foundational Knowledge Builder being developed at the University of Washington, and we are exploring conditions of classification and storage of 2-D and 3-D images to enhance knowledge-based retrieval.
