Time Traveler: An interactive 3-D media system will be a fundamental means of resource interpretation. The system, configured as a multimedia workstation built into a small, hemispherical "media" room, will provide a user controlled 3-D travel experience through an electronically simulated cultural environment. Through 3-D video and holographic projections in free space, the computer information base will permit the user to view and participate in the dramatization of selected historic scenes. A range of the sensory experiences associated with each historic scene will also be available to system users. The virtual reality created by the surrogate time traveler will communicate sensory impressions about tactile, visual, olfactory, and audio characteristics as appropriate to the particular experience. To convey a sense of the socioeconomic context of the site and historic time, the 3-D system will display the human activities of the daily routine, interpreting the community events and historic values associated with each simulated scene. The building technology and construction process for each structure will be accessible for viewing, and the mechanics of industrial exhibit will be demonstrated in the animated 3-D presentation. The system will depict natural and man induced changes to the buildings and sites portrayed in the scenes. The system will also display the processes of building restoration to demonstrate contemporary rehabilitation techniques and uses of substitute materials. Users will be able to tailor the information presented according to their own sensitivity, interest, and need. User selections will be specified by eye contact with objects in the display, and by spoken responses to voice queries presented in simulated dialogue with characters portrayed in the historic scene. Choices as to the issue path (natural, social, economic, folk, scientific, design, technological) that the user wishes to follow through the information base will be presented at each nodal segment in the unfolding of the cultural scene. As progressive selections are made, the system's information "filter" will recognize preference patterns, and will progressively offer information choices more relevant to the taste of the user.
